EDITOR’S BLOGA well-dressed stranger stopped by
the yard the other day and asked:
“Now that you’ve logged off that land,
want to sell it?” I winced as I imagined
him thinking that we were high-grading
the woods and cashing out.

2 Northern Woodlands / Summer 2013
Recently, I have been hiking with my infant son. It’s hard to know what, if
anything, he takes from these forays. At two months, it’s a safe bet he’s not
counting the chickadees, but he seems to enjoy being outdoors.
As for me, I find this time together deeply satisfying. As a typical self-
referential human, I cherish the landscape around my home not just for its
own sake, but as a place made special by personal associations. Walking old
trails with my still astonishingly new child, I have the sense of re-reading a
favorite story and finding fresh meaning tucked in the pages.
There is a bald patch in the old sheep pasture above our house where each summer the
turkey hens de-bug their feathers by rinsing in plumes of dust. On this same spot, our daugh-
ter embarked on her very first sled ride and, four years ago, a bobcat thrilled us all by posing
for a moment before slipping back into the tree line. Now the site has taken on yet another
distinction, as the place where I first saw my son smile.
Northern Woodlands is also a home territory of sorts. Since this spring, I’ve made a proj-
ect of reading our full magazine archive, starting all the way back with the first issue in 1994.
Then, as now, there were articles focused on tracking tips, habitat enhancements, timber
harvests. Also consistently across the years, each issue offered new learning and unexpected
perspectives.
In all of our educational efforts, the Center for Northern Woodlands Education encour-
ages people to find “new ways of looking at the forest,” and in doing so, to deepen their own
intimacy with the land. Through this sense of belonging comes an understanding of our
shared responsibility for the future of the Northeast’s wooded landscapes.
We could not do this work without your help. Subscriptions do not cover the cost of this
magazine, nor do they pay for materials we provide to schools and other educational groups.
As you read this, our nonprofit is just rounding the corner into the last quarter of our fiscal
year. If you haven’t supported us yet, would you please consider a donation?
Now is a great time to contribute. Thanks to a generous supporter, between now and June
30th, donors will have a chance to win a Helios2 Orvis Fly Rod Outfit. You can also buy
extra tickets on our website (see page 47 for details), a great way to start the summer while
helping a good cause.

A Look at the Season’s Main Events
JuneEastern tent caterpillars are feeding on
pin cherry leaves / Gray treefrogs return
to the woods after breeding to hide in
knotholes and tree cavities for the rest
of the year. Listen near vernal pools for a
cross between a loud trill and an air raid
siren / Young cattail shoots can be peeled
and sautéed. Adding a little soy sauce and
ginger doesn’t hurt / The eight-spotted
forester is a moth that flies in the day and
is as pretty as a butterfly
June 21: The summer solstice, when the
sun is at its northernmost position in the
sky, directly over the Tropic of Cancer at
23.44°N. It’s the first day of summer in
the northern hemisphere and the first day
of winter in the other half / In years past,
whippoorwills were heard on warm June
nights, but this is not so common anymore
/ The male black-throated blue warbler also
has a black face and black sides. He sings
a lot, continuing late into the summer
Mashed up jewelweed plants applied
to poison ivy and other rashes will relieve
the inflammation and itching / Ruffed
grouse chicks are eating more vegetable
matter and fewer invertebrates. High-
protein insect food is the norm only
during their first few weeks of life /
Groups of whirligig beetles often swim in
circles on the surface of the water. Each of
their two eyes is divided in two: one half
looks up, and the other looks down, below
the waterline
White pines are releasing a lot of pollen,
often visible in the air and on cars /
Female hummingbirds are each laying
two oval, pea-sized eggs. Busy chasing
other males and females, the males take
no part in caring for the nestlings / The
snapping turtles now laying eggs have
been around for 200 million years. They
pre-date dinosaurs, plenty long enough to
develop a crusty disposition / Poison ivy
flowers are producing abundant nectar. It
makes good honey
Loon chicks – either one or two – leave the
nest within a few hours of hatching and
head for water. They nestle into the feathers
on the back of a parent to rest and keep
warm / Young great blue herons are large,
walking around on branches, and appear
very near fledging / Serviceberry, aka
juneberry, provides summer fruits for wood-
peckers, eastern kingbirds, thrushes, wax-
wings, orioles, grosbeaks, red-eyed vireos,
and cardinals / Wild leeks are blooming
Canada lilies are in flower; these glorious
tall plants are found in rich, moist field
edges and marshes / Harvester butterfly
larvae rely on alder blight aphids for food.
The orange and brown caterpillars are now
gobbling up aphids – they’re the only truly
carnivorous butterfly in the country / The
full complement of summery flowers is
blooming: daisy, black-eyed Susan, sweet
white clover, and red clover are a few that
seem to go especially well together
August 12 & 13: Perseids meteor shower.
A good year, because the crescent moon
will set just as the shower is gearing
up / Monarch adults are not only found
on milkweed. They will visit red clover,
thistles, and sunflowers, too / Red-backed
salamander eggs hatch over the next
couple of months. They are entirely ter-
restrial and the larval stage is completed
within the egg / Green frogs stay near
water and will jump in with a splash and a
yelp if startled
The sulfur shelf mushroom (Polyporous
sulphureus), a choice edible, grows on dead
wood and is found from July to October.
It is bright orange on top and a rich sulfur
yellow on the underside / Periodical cicadas
are out and calling. They lay eggs in slits in
tree bark. After hatching, the larvae fall and
burrow into the ground. They’ll spend 13-17
years feeding on roots, before emerging as
adults / Joe Pye weed is blooming, a large
plant of wet meadows
Piles of night crawler castings stand
out on closely clipped lawns. Flashlight
beams on warm, rainy nights indicate
that the neighborhood kids noticed, too /
Trout prefer feeding when the water
temperature is low, primarily at night or
early in the morning / Look for anglewings.
Most of these butterflies, in the genus
Polygonia, live in the forest and look
like dead leaves / Tiny spring peepers,
recently metamorphosed, are leaving their
nursery pools
Woodcock chicks have been foraging with
their mothers for about a month, but now
that they can fly, they’ll leave the family
unit / The most important summer bear
foods are wild lettuce (three species),
jack-in-the-pulpit, and jewelweed / The
nectarless flowers of jack-in-the-pulpit
smell like fungus and are pollinated by
fungus gnats / The white, root-eating
grubs of Japanese beetles can make
lawns look ratty. Adults are emerging and
heading for the roses
The active little winter wren will search
for food by turning over leaves and pieces
of debris, probing under loose bark, and
unearthing food items from root wads /
Listen for the dull whistle-like call of the
snowy tree cricket. Count the number of
“throbs” in 13 seconds, add 40, and you
will have the temperature within a few
degrees (F) / A fringe of stiff hairs on the
hind feet of northern water shrews allows
them to run across the water’s surface
The appeal of wasp larvae is stronger than
a bear’s dislike of being stung. They’ll use
their teeth to tear apart logs in search of
wasp nests / Woodchucks are fattening up
and will consume up to one and a half
pounds of green vegetation a day / Whitetail
bucks are tearing away the velvet on their
antlers and polishing them by thrashing
them against branches / Now ravens are
eating corn, blackberries, and other fruits.
In winter, they eat mostly carrion

EDITOR’S note
On the first 70 degree day of the year we took a UTV ride up to the top of the ridge behind
camp, G and I. She’s originally from Wyoming, so she sees the forests around here with fresh
eyes. Fresh wonder at the hepatica growing amidst the exposed roots of a monarch red oak,
at a sentinel barred owl on a trail-side snag watching somberly as we drove by. We stopped
when we could drive no farther and made the final ascent on foot – about a quarter mile
up the last knob to the top. The shelves beneath the summit were a mixture of beech and
yellow birch – this is southwestern Vermont so the whole mountain is hardwood and white
pine – but at the very top there was a smattering of mature red spruce; we could probably count the spruce
trees on our 20 fingers. From the valley floor the towering trees look like a little spruce fez perched atop the
mountain’s head.
“Where did they come from?” she asked, running her fingers along the fissured bark. “On the wind?
Birds?” We hadn’t seen another spruce all day. And while I didn’t really know the answer to her question,
having recently read Drew, Alan, and Charlie’s story on forest paleoecology (page 40), and Meghan Oliver’s
piece on Alpine Plants (page 32), I ventured a guess that maybe they’d always been there. That after the last
glacier retreated, and the land warmed, it was the spruce that first colonized the mountain, and that all the
other trees were the interlopers that had spent the last 10,000 years chipping away at their turf.
Whatever the real answer, this idea of seeing a forest as a logical system, and not just a collection of
random, individual trees, is the foundation of contemporary ecological thinking and pretty much everything
we write about. And it’s not just plants – it’s all of nature. You can look at the New England cottontail as a
relic of the past in the same way you look at a copse of conifers on a mountaintop. Three hundred years ago,
the settlers set the stage for New England cottontail proliferation by cutting down the forest; 100 years ago,
they abandoned their farms and the resulting perfect habitat caused rabbit populations to explode. Trees
grew back, habitat declined, the rabbits disappeared. As you’ll read in Charles Fergus’s story on New England
cottontails on page 20, it’s quite a bit more complicated than this, but this notion of cause and effect, the sweep
of history, and an element of impermanence is at the root of everything we see out there.
I’m pointing out the obvious to this audience. Everything we do in our woods this summer – the trees we
cut (or don’t) for firewood or sawlogs; the trout we keep for dinner (or release) – will be done with a system
in mind. But this is not so obvious to people outside our tribe. Hence the protectionist philosophies that focus
on the individual rights of a trout or a tree versus the population as a whole; or the nursery tag on a Norway
Maple pointing out the tree’s individual strengths (shade tolerant!), oblivious to the fact that it has no place
in our native forest.
Because many people don’t see the systems in nature, because it’s easier to see individuals, making the
New England cottontail the face of young forest habitat is a brilliant PR move. It’s not unprecedented
– Audubon’s doing a similar thing with their Birder’s Dozen campaign, which links declining young forest
habitat to recognizable songbirds – but it’s another good example of how the conservation community has
begun to anticipate epistemological, as well as ecological, realities. If you propose an overstory removal as
part of an early successional habitat improvement project, you’re speaking to no one but wonks. If you say
nothing and just show up with a feller-buncher to do the angels’ work, you’re leaving yourself open to all kinds
of misinterpretation. But if you say, Let’s go save this rabbit, well now you’re getting somewhere. Now you’re
opening the door wide enough for others to fit in.
Some will point out that putting energy into reviving a practically extinct rabbit species that’ll probably
never have ideal habitat again is a misallocation of resources, akin to the hard reality that in the big picture
a chervil-picking party is not going to fix a town’s invasive plant problems. And this is probably true. But it
overlooks an even bigger picture: that it’s crucial to engage as many people as possible in conservation efforts.
Recognizing how humans organize their thoughts and motivations, how they learn and interact with the
world around them. That’s a system, too. NW

letters to the EDITORS
At Your ServiceTo the Editors:
As I have stated many times in previous letters,
I always enjoy and learn from Virginia Barlow’s
regular column, The Overstory, which spotlights a
tree or shrub species. Her last one on serviceberry
with its many common names was another of
these gems. I often have some additional informa-
tion or, hopefully, illuminating remark to send in
response, and this time is no exception.
As Barlow wrote, Amalenchier has several
common names. Serviceberry is an apt one that
I have heard (and believe) is based on the story
that pioneer women/homemakers welcomed the
June fruiting of this tree/shrub because it was
the first fruit they could obtain for jams, jellies,
and pies. While the fruit was smallish, and not
as tasty as other edible fruit, it would “serve.”
Another story (that I do not give much credence
to) was that it flowered at the time the frost was
out of the ground, and so bodies of those who
had died during the winter and stored in the ice-
house could then be formally interred. Bouquets of
serviceberry were part of the funeral “service.”
Larry Hamilton, Charlotte, VT
The Neighborly Beaver To the Editors:
I loved Robert Kimber’s article about co-existing
with beavers. We are active tree farmers and relish
our life on Moose Mountain, where there is a huge
old mill pond on our land. We have lived here for
38 years. There have been three beaver colonies
since we have lived here, with the last one having
been more or less successful for nine years. I think
they will be moving on this spring. They have really
eaten just about everything they can find within a
reasonable range from the pond.
Over the years some of them have become
quite tame. I have never hand fed them, but I bring
them apples, and in the past few years poplar
branches that I have gleaned from all over the
Upper Valley. I often fear arrest for my pilfering.
I know that when they move on they will be in
extreme danger from cars, people who don’t want
them around, and the many predators that exist
here. But we are encroaching on them, not the
other way around. Our pond will diminish and the
moose and deer will return for the lush grasses
that will grow as the moist, fertile soil dries out.
Last spring, the adolescent beavers left earlier
than usual. We had two parents and two kits
during the summer. There are five ponds and six
dams – they wintered in the lowest pond. The main
pond was too shallow for them and they didn’t repair
that dam. It is fascinating watching them make these
major decisions. They are currently living in a hastily
built bank dam with a meager food supply. The water
level has not been consistent this winter. In the past
few days, I have seen fresh tracks and cutting of the
few beech trees that are left. I’m sure it’s not a first
choice for food. I was able to make it to a new poplar
supply in the deep snow yesterday and brought them
back a pile of treats. I have thousands of pictures of
them and am enclosing a few from last March.
Kay Shumway, Etna, NH
Stay SharpTo the Editors:
As an arborist of some 35 years, I’d like to add a few
tips of my own to Carl Demrow’s Tricks of the Trade
column on sharpening chainsaws (Spring 2013).
As you can imagine, I am frequently asked (usually
by a homeowner) about sharpening saw chains.
The first thing I tell them is, “It’s not rocket science.”
Carl’s assertion that if your file is off by even a
hundredth of an inch you will decrease the effec-
tiveness of your chain may be true, but not enough
that you would notice in the field. When we get into
dirty wood or a buried piece of barbed wire, we’re
more concerned about getting the job done than we
are about that hundredth of an inch. As long as the
angles are reasonably close and the leading edge of
the tooth is sharp, the chain should cut well enough.
The height of the rakers (depth gauges) is probably
more crucial than those angles. Even new chains
don’t cut as well as they should.
How can you tell if a chain needs to be sharp-
ened? Look at the leading edge of the teeth. If
the edge is dull, the tooth is sharp. If the edge is
shiny, the tooth is dull. But you’ve got to look sharp
because the shine can be subtle. File until the edge
is dull and now it’s sharp. Got it?
As for those new chains, I always find that the
rakers are too high. Filing rakers to the proper
height can be tricky, so use a gauge.
The best talk I ever went to for chainsaw safety
and maintenance was given by Dan Tilton of Tilton
Equipment in Rye, New Hampshire. It should be
required of anyone buying a chainsaw for the first
time.

Photographer John Timmis captured this
image on Wilson Pond in Greenville, Maine.
“She would disappear underwater going
after aquatic vegetation,” he remembered,
“causing the flies to leave her body – but
they would be circling around waiting for
her to rise back up. Seeing all of those flies
on and around the moose (and the leeches
attached to her legs) gave me a new
appreciation for the things animals have to
endure in their daily quest for survival.”

No Clear-Cut AnswerTo the Editors:
Recently, I’ve seen a number of photos and refer-
ences to clearcutting and even-aged management
in the magazine. Lately there have been increasing
reports of heavy cutting (clearcutting?) coming
from the Adirondacks, all since the change of
timberland ownership a few years ago. Foresters,
hunters, loggers, and fishermen have expressed
concern to me, especially regarding impacts on
wildlife. We know what happens to the deer
herd when yarding areas are clearcut, but there
are negative consequences for other wildlife,
too. Those hollow trees are shelter or nesting
areas for fishers, raccoons, owls, squirrels,
bears, wood ducks, and honey bees, to name
just a few. In a fire one time, I saw 12 flying
squirrels sail out of a burning yellow birch. The
wildlife is in there, you just don’t see it. In a clear-
cut those hollow trees are on the ground. Even-
aged management results in the regeneration
of thousands of seedlings and sprouts per acre,
which eventually grow into a dense stand blocking
the sun and inhibiting the growth of vegetation on
the ground that wildlife use as food and cover. The
extreme example would be a pine plantation with
nothing on the ground but pine needles. Wildlife
avoid such places like the plague. Adirondack
hunters are still dealing with such conditions on
some New York State Forest Preserve lands that
were clearcut years ago. And what happens to
I didn’t realize how much she was picking up
until she handed me her poem. I’m not sure if
it’s just the bias of a proud grampy, but I thought
the poem was really good for someone her age.
Sap
I love sap it comes from trees!
I feel the breeze.
I feel like I can fly,
I can see the sky.
I hear the sap pop,
It goes drip drop.
It is fun!
I can feel the sun!
I feel like I have a crown.
The sun goes down,
I don’t hear a sound.
I feel surrounded by trees.

Floor ItTo the Editors:
The story From Forest to Floor (Spring 2013)
about the use of local woods to build a gym floor
by the community reminds me of a similar effort
in Berlin, Vermont. The dance floor installed in
1953 in the Capital City Grange Hall #469 had
finally worn out. It was replaced with a beautiful
new floor made of Vermont maple – harvested,
milled, and installed by local craftspeople. The old
floor was removed by community volunteers and
recyled/upcycled into other floors, a mandolin,
frames, pens, jewelry, and, of course, stove wood.
Check it all out at capitalcitygrange.org.
Merry “Flora” Kay Shernock, Northfield, VT
To the Editors:
From Forest to Floor (Spring 2013) was an
enjoyable article, but could be misleading. If a
sawmill does not have a metal detector, it most
likely would require a logger to cut off the butt log
above where any metal taps or nails to support
the cover might be grown over. This would mean
cutting off about five feet from the base of a
butt log. A landowner planning on selling tapped
sugar maples should check with the sawmill to
determine the mill’s policy regarding acceptance
of tapped sugar maple butt logs.

call her. Ellie and her younger brother have been
helping me with my little maple syrup operation
(25 taps and growing) since they were big enough
to ride in the sled I use to haul my old milk cans
for collecting sap. I am trying to expose them
to the wonders of my woodlot in the hope that
one day one or both of them will take it over and
continue to work if for syrup, firewood, lumber,
and wildlife habitat. Ellie has been a good helper,

Sex and the Single Bird
Story and photo by Bryan Pfeiffer
Blackbirds do it. Chickadees do it. Even
educated emus do it.
Some birds are cheaters. Their trysts,
dalliances, one-morning stands, and
other infidelities would constitute a racy
script for a wildlife soap opera.
But first, the faithful: In the vast
majority of bird species, one male and
one female unite for the purpose of
raising young. In this classic form of
monogamy, or “single marriage,” the pair
stays together either for a single breeding
season (the case among most songbirds)
or for as long as they both shall live (in
geese, gulls, and swans, for example).
Among the rest (or the restless, as the
case may be), polygamy, or “many mar-
riages,” ranges from casual to calculating.
A male red-winged blackbird mates
with a number of females, and each tends her own nest. This
most common form of infidelity is called polygyny, “many
women.” The general hypothesis is that females prefer to mate
with the male that can defend the best territory (size and quality
matters) or exhibits some other evidence of having better genes.
The superior redwing’s harem averages five females, but he may
mate with as many as 15.
It might seem that a female and her hungry young would suffer
if the male in her life was preoccupied with a dozen or more
partners. But polygyny sometimes occurs with conditions favor-
able to a neglected mother: an abundance of food, for example,
or precocial young more able to fend for themselves, which is
the case for the occasionally polygynous ruffed grouse.
The point here is that polygyny doesn’t only benefit males.
Out in the marsh, as male redwings call honk-a-REE, the female
is calculating. She figures that joining the harem of a male with
upscale territory is better than monogamy on inferior turf. Her
offspring prosper if she chooses a king’s palace over a loser’s
hovel.
But in matters of avian romance, turnabout is fair play.
Spotted sandpipers display classic polyandry, or “many men”
– a single female mating with multiple males. Oh, sure, she finds
a mate. She might even help him incubate eggs and raise their
young. But while the male does most of the parenting, she’s on
the prowl.
A female spotted sandpiper often leaves her first mate to
breed with a second. She might help rear young from both nests
at the same time (simultaneous polyandry). But sometimes she
abandons her first family and devotes her parental energies only
to her second (serial polyandry).
BIRDS in focus
Paternal care of young is rare in birds, but those devoted dads
may have been customary earlier in avian evolution. One pale-
ontologist studying fossilized dinosaurs positioned over eggs
concluded that incubating adults were predominantly male.
And the eggs in their care seemed too numerous for the lone
adult, suggesting that dad was tending to a collection of eggs
from more than one female.
We still have dinosaurs exhibiting this behavior: the emu and
some other ground-dwelling birds. (Remember, only non-avian dinosaurs went extinct.) A male emu is often the lone parent
to an oversized brood from several females. Also noteworthy is
that the emu is among our most primitive birds, relatively close
in lineage to its therapod dinosaur ancestors.
Much further along from emu evolution is the cheating
chickadee. Male and female black-capped chickadees usually
pair up as their winter flocks begin to disperse in early spring.
They are monogamous. Well, almost.
Even as she’s laying eggs fertilized by her mate, a female
chickadee sometimes sneaks off for copulations with another
male, only to return to her nest to lay extramarital eggs. So, in
our inventory of mating strategies – monogamy, polygamy, poly-
andry – it turns out that chickadees are simply promiscuous.
In all these examples of feathered infidelity, the research
varies, and I advise readers to be wary of complete or conve-
nient explanations. Avian affairs are no different than our own.
In other words, when it comes to relationships, as you might
expect, “it’s complicated.”

Northern Woodlands / Summer 2013 11
By Michael Snyder
Jackie Lyman, NH
When two tree branches or stems grow in close proximity to each
other, it is possible that they’ll eventually grow large enough to
touch. If the bark becomes abraded, say through rubbing caused
by swaying in the breeze, it is possible for them to become
physiologically – or functionally – connected. This is the basis
for grafting.
People have been grafting plants for thousands of years, most
commonly to propagate desirable traits such as flower color,
fruiting, size, or shape by intentionally joining together two
different plants. But both shoot and root grafting occur naturally
in trees, without human assistance. In fact, some scholars have
suggested that horticultural grafting practices first emerged
as early humans attempted to mimic the natural grafting they
observed in the wild.
The result of grafting, either natural or horticultural, is a
genetically composite organism functioning as one plant. That
is, grafting results in the creation of a compound genetic system
by uniting two or more distinct genotypes, each of which main-
tains its own genetic identity throughout the life of the grafted
plant. This is why, for example, a branch of a red-flowering rose
grafted onto a white rose stock will continue to produce red
roses rather than white or pink hybrid roses.
Here’s how grafting works. Just under the bark of all woody
plants is a layer of living cells called the cambium. These cells
divide and multiply to create bark tissues to the outside of the
cambium, and wood tissues to the inside. This is how tree roots,
stems, and branches grow larger in girth. And it is the most
recently created of these cells on each side of the cambium that
perform the vital functions of transporting water and minerals
gathered by the roots from the soil up into the tree, and the
carbohydrates made in the leaves down into the rest of the tree.
Think of the cambium layer as the tree’s plumbing.
When the plumbing system of one tree successfully fuses
with that of another, a graft union is formed. But this can only
happen under specific conditions. First, the tree parts have to
be biologically compatible. That’s why such fusions are more
common among the branches, stems, or roots of one tree or
between two individual trees of the same species. But it can
happen between two trees of closely related species. The more
different the species are taxonomically, the less likely a graft can
occur between their parts. Indeed, no such grafts have ever been
documented between tree species in differing families.
This tree seems to have had a branch or a second tree growing from it, then it died, but then it seemed to have grafted itself back. Would appreciate learning more about this.
Other requirements for this amazing bit of tree magic are
that the tree parts be in direct, prolonged contact; be under
pressure; have sufficient moisture and protection from the
elements, insects, and pathogens; and have those cambial cells
properly aligned. Okay, it’s biology and not actually magic – but
it might as well be considering how many things have to go right
for it to work. Among northeastern tree species, natural shoot
grafting is known to occur in sugar maple, black cherry, red
and white oak, sycamore, willows, beech, eastern hemlock, and
white pine (as pictured).
It should be noted that there are many occurrences of
branches or stems growing very closely together, even touching
in what would appear to be a graft union, but that turn out to
be separated by layers of bark. These are not true graft unions,
because they lack physiological connectivity. The one in question
here would appear to be a true graft because the lower portion
of the one stem appears dead, while its upper part appears to
be alive and well, suggesting a physiological reconnection has
occurred. Ah, the near-magic of tree biology.

The Intriguing Woodchuck
Consider the ubiquitous woodchuck (also known as the ground-
hog); an animal found from Labrador to Alabama; through-
out all of the eastern U.S., west to Kansas, Nebraska, and the
northern tip of Idaho; from eastern Alaska all the way across
the southern half of Canada.
We’ve all heard that Punxsutawney Phil will emerge from
hibernation on February 2, look for his shadow, and predict
the weather for the next six weeks. While this is legend, of
course, male woodchucks will interrupt their hibernation
in late winter and make forays across the snow to search
for female burrows or to establish breeding territories. Such
activity elevates the body temperature to a level necessary for
spermatogenesis to occur, guaranteeing that
males will be ready when it’s time to mate.
While the males are working on their sper-
matogenesis, prospective female mates are sleeping
in. This saves vital energy for the rigors of repro-
duction and raising the family. Woodchucks
breed immediately after the females emerge in
March, and, following a month-long gestation,
their young are born just in time for the green-up
of succulent vegetation.
Everyone knows about the woodchuck’s
penchant for peas, carrots, young corn, and
other vegetable garden and farm crops, but the
incredible diversity of foods that woodchucks
consume can still come as a surprise. I remember being dumb-
founded as I watched an odd beaver-like animal swimming
to shore with a pond lily stem in its mouth. Upon landing, its
identification was clear. I watched in fascination as the ground-
hog sat upright, grasped the stem in its paws, and consumed it
before reentering the water to do it all over again.
In our region, common foods include sedges, grasses, wild
strawberries, plantain, clover, alfalfa, goldenrod, trout lilies,
dandelions, daisies, vetch, and the fine stems and fruit of apples,
serviceberries, and blackberries. In early spring – before the
green-up of herbaceous plants – the buds, bark, and tender
twigs of sumac, dogwood, and black cherry are also consumed.
Woodchucks eat occasional invertebrates, including crickets,
grasshoppers, snails, and June bugs.
Like most rodents, woodchucks’ hind feet are larger than their
front feet. Five toes will show on hind feet tracks and the stout-
clawed forefeet register only four toes. The pollex (or thumb toe)
does not register in tracks because it is reduced to a small stump
tipped with a tiny blunt nail (see photo). The most distinctive
features to look for in woodchuck tracks are the one-three-one
toe arrangement of the hind feet and the pock-marked appear-
ance of the track impression, which is created by knobby pads
Story and photos by Susan C. Morse
TRACKING tips
that protrude from the fleshy base of the feet. The tiered arrange-
ment of three and two pads on the front feet, and a semi-circle of
four pads behind the long toes of the hind feet, help differentiate
a woodchuck track from that of a raccoon or beaver.
We’ll often see a woodchuck near its burrow. Fresh dirt pushed
out of the entrance reveals that a groundhog is actively using and
retrofitting its subterranean refuge. Fecal matter is rarely found,
because it is deposited within the burrow. When exclusively in
use by a groundhog (and not enlarged to accommodate other
occupants, including foxes, coyotes, and raccoons), burrow
entrances measure between five and six-and-a-half inches in
diameter. Evidence of teeth marks on tree roots near a burrow’s
entrance can sometimes be found.
I once watched a woodchuck gnawing on a root, followed
by cheek-rubbing the fresh bite marks. I am convinced that the
woodchuck was scent-marking, using its saliva and secretions from
sudoriferous (sweat) facial glands to communicate its presence.

Swamp Gold: Edible Cattail PollenIt can be difficult for beginning foragers to make the leap beyond the most familiar wild foods. For those
who want to expand their repertoires beyond ramps, fiddleheads, and blueberries, I cannot think of a
better food than the edible pollen of the common cattail (Typha latifolia). It is unmistakable, fun to gather,
easy to process, and tastes delicious.
The greatest challenge in harvesting this unusual food is catching it during its brief season. During
the late spring and early summer, the cattail’s flowers start to form, looking like two green hot dogs
impaled on a stick, one on top of the other. The one on the bottom is the female flower that will produce
the familiar fuzzy puffs of seeds in the autumn. The one on top is the male flower, which generates
great quantities of wind-blown pollen. The problem is that this pollen disperses quickly once it forms.
(The season for cattail pollen can be as short as a week!) If you have access to a large cattail marsh,
start watching it carefully in mid-June. When a gentle tap to the cattail stalk releases a cloud of yellow
dust, it is time to gather. Do not delay, especially if there is rain or wind in the forecast. They will wash
and blow your harvest away.
To gather the pollen, I prefer to use a clean, dry, milk jug. I bend the pollen-covered spike into the jug
and shake. A fine yellow dust will settle into the container along with fibers from the flower itself. Over
the course of an hour, I have gathered two to three cups of pollen from the small riverside marshes near
my home. Those that live near large lakeside marshes can expect to gather up to a quart per hour in
good conditions. I sift the inevitable mass of fibers, insects, and spiders from the pollen by suspending the
mixture in a jelly bag or cheesecloth in a half-gallon glass jar. This keeps me from losing the fine pollen
dust to the air as I shake it.
The pollen itself is beautiful, and if it didn’t taste so good, I would be tempted to keep it on my kitchen
windowsill. Supposedly, it can keep for quite some time. I wouldn’t know. My family usually scarfs down
all of our cattail pollen baked goods on the day we gather. We use it to replace about 50 percent of the
flour in the goodies we prepare. Try something simple first, like the pancake recipe here. Whatever you
choose, I doubt you’ll be disappointed by the golden color, the mild flavor, or the adventure.

Deaf in the WoodsDo you remember your answer to that youthful
question: if you had to be one or the other, would
you rather be deaf or blind? Most of us believed
we’d never have to be either, though my answer
– blindness – never put me in the majority. To
lose sight felt scarier to most because we rely so
much on our eyes to navigate the world. But to
lose hearing, I believed, was to live in silence, and
that felt terrifying.
Deafness would mean losing music and bird-
song. They go together. One of the earliest musical
instruments is a 4,000-year-old flute made out
of vulture bone, found in southern Germany.
Anthropologists believe that some of the first
human songs were imitations of avian singing.
Composers from Maurice Ravel to Philip Glass
listened to birds. And poets – think Robert Frost’s
evening thrush and Emily Dickinson’s sparrows in
the garden – are avid translators. To lose birdsong
is to lose a woodland language.
As I’ve gotten older, my understanding of what
it means to be deaf has changed and I’ve lost
my fear. I’ve watched deaf friends communicate
with American Sign Language, and read what I
could put my hands on, including When the Mind
Hears, A History of the Deaf, by Harlan Lane. Sign
language is a manual language as expressive as
verbal language, if not more so. It’s metaphorical
speech linked to the physical world and beauti-
fully spare in ways hard to imagine for those who
don’t speak it. To say a deaf person can hear with
their eyes may seem naïve, but it is close to the
truth. The entire body and mind becomes an ear:
music comes through the subtle vibrations of
the air on skin. Perhaps the deaf hear birdsong
through voices in the mind we can’t hear.
I’d been in denial about my own hearing loss
for a few years, but one summer morning in the
White Mountains, my son asked me what bird
was singing. I couldn’t hear it. I got exasperated
and kept asking where the sound was coming
from. “Right there,” he said, pointing at a rock.
The blackpoll warbler was singing about four feet
away. Losing that song sent my head reeling.
It felt like an erasure of a small but important
piece of my experience of that place. Sound is an
unexpectedly large component of the visual world.
What other aural pieces were missing?
Presbycusis – the name for age-related hearing
loss – has the unfortunate ring of a religious
LAN
G ELLIO
TT
disease (Greek presbys for elder and akousis for
hearing). It occurs when stereocilia – hair cells
inside the middle ear that turn fluid pressure
into electrical stimuli – begin to die. Birders are
sensitive to lost hearing because the enterprise
depends on it. Average birdsong frequencies lie in
the 4,000-Hz range. But many go up to 8,000-Hz
(human speech is 3,000 Hz and lower). High-
frequency hearing loss tends to kick in at 3,000
Hz. Song may represent well over 75 percent of
what a bird watcher sees in the woods.
So, it’s a bugaboo. For example, I no longer hear
Louisiana waterthrush, a harbinger of spring on
our brook. At first, I thought they weren’t nesting.
Other birds have fallen out of earshot: winter
wren, brown creeper, golden-crowned kinglet,
and northern parula, to name a few. It’s like losing
friends, only they’re still around.
Fortunately, there are workarounds. Conventional
hearing aids can be modified to amplify sound
at only the higher frequencies, thus avoiding
the problem of sensory overload. SongFinder
by Nature Sound Electronics converts high
frequencies to digital signals, then divides and
lowers them. You hear the lost songs only when
they sound lower – like a record playing at a
slower speed. Another product is a mobile app that
picks up songs via the mic on your smartphone
and converts them to graphic sonograms – the
sheet music of birdsong.
There are behavioral changes that can help
age-related deafness, too. While moving out of
the loud cities we tend to live in is one option,
that’s often impractical. I’m going to try to rely
more on sighting songbirds. I’ll try to learn to pick
up the lower-frequency pieces of lost songs I can
still hear. I’ll focus on learning the call notes of
certain birds. I’m going to spend more time with
ducks and shorebirds. I’m going to learn to lean
into the quiet, too: my small corner of the deaf
world I will relish. That means learning some sign
language and communicating with deaf friends to
learn how their minds hear by translating sounds
from vision, thought, and feeling. Finally, I’m going
to prevail upon my wife, children, and friends to
learn some of these songs, bird along with me,
and tell me what’s coming through.

Take a Bike! And Feel the FlowWhile the difference between a deer trail and a
hiking trail may be obvious, what makes a trail
good for feet is not always what makes a trail
great for tires. Whereas hikers (and deer) tend to
be destination oriented, mountain bikers look for
trails that allow them to experience the woods
above, around, and below them.
Hardy Avery of Sustainable Trailworks in
Morrisville, Vermont, has been building mountain
bike trails for much of his life. When hired to
design and build a trail, Avery begins by talking
to the landowner about management plans they
may already have in place. This collaboration is
key to planning and designing a trail that respects
other land users, protects vulnerable ecosystems,
and (when on public land) follows guidelines set
by the Agency of Natural Resources.
The next step is to assess the terrain. During
this stage, Avery gathers information about soil
types, drainage, and slope, and then begins to
conceptualize possible routes. He decides where
and how to bridge wet spots and streams and
how to connect various high spots along the
route. At just about every step, Avery uses a cli-
nometer – the goal is to keep the slope under 10
percent. This information is essential in designing
a trail that flows across the terrain.
As Avery gets to know the woods he’s work-
ing in, he determines where the control points
are, both negative and positive. Negative control
points are things he wants his riders to avoid, like
swamps and cliffs, and positive control points
are the naturally beautiful features – like vistas
or waterfalls – that he wants his riders to see.
GPS coordinates are taken and a map begins to
emerge. At this point, Avery begins to hang flags
at eye level along the envisioned trail corridor,
looking both forward and backward and con-
stantly checking his clinometer. The speed of the
rider is of constant concern. A seasoned mountain
bike rider himself, Avery knows that riders like
rolling terrain and kinesthetic diversity. Once he
rough flags the route, he can estimate the cost
of the proposed trail (on average about $5 a foot).
Once the trail builder and the landowner agree on
the price, wire-pin flags are placed in the ground
and the building can begin.
Trail builders rely on a variety of tools to con-
struct trails, including a McCloud (a flat, square
shaped blade with a cutting edge on one side and
a rake on the other that’s used to remove berm)
and a Pulaski (half axe, half hoe). Trail builders also
use a sledge hammer, wheelbarrow, and basic
landscaping tools like pruners and rock bars. On
larger jobs, Avery uses a 1.5-ton mini-excavator.

Night Vision: How Animals See in the DarkI’ll always remember the time I ran into a wire fence at dusk. I was taking a shortcut through some
woods, and the impact sent me tumbling. Even when I looked carefully, I could barely discern the thin
strands of wire in the gloomy evening light.
All vertebrates share the same basic eye structure: a pupil that dilates or constricts to control how
much light enters the eye, a lens to focus the image onto a light-sensitive retina, and nerves that relay
the information to the brain. Yet humans flounder with the departure of daylight, while many animals
are able to forage and hunt by night.
How do animals see in the dark? For one, they have big eyes. Nocturnal hunters like owls and cats
have pupils that, when open wide, cover the entire front of the eye. So do tree frogs, which have to be
able to jump from branch to branch. In owls, eye size approaches the extreme: their eyes occupy over
half the volume of their skulls.
There are also physiological differences between the eyes of nocturnal and diurnal animals. Owls’
eyes are tubular rather than spherical, with a very large lens positioned close to the retina. This structure
allows a lot of light to register on the retina, but at the expense of flexible focusing. Owls are thought to be
somewhat far-sighted. Tubular eyes cannot rotate in their sockets like the spherical eyes you and I have, so
owls compensate with incredibly flexible necks that allow them to turn their heads 270 degrees.
Many nocturnal animals have a mirror-like layer, called the tapetum, behind the retina, which helps
them make the most of small amounts of light. Light that passes through the retina is reflected off the
tapetum, giving the retinal cells a second chance to sense it. This makes some animals’ eyes shine in
the glare of car headlights. The color you see is the pigment on the inner layer of the retina.
At the heart of all vision is the retina, which contains two types of light-sensing cells: rods and cones.
Cones account for color vision but require bright, focused light, whereas rods can sense very dim,
scattered light, but don’t produce a color image. While each cone has its own brain connection, multiple
rods are wired to a single brain connector. This pools the information collected from the rods and creates
a stronger signal, but the image is less defined.
As you might expect, the retinas of nocturnal animals are packed with rods and have few cones.
However, because their large eyes create a big image that is focused on a big retina, they capture some
detail despite the shortage of cones.
In our eyes, the cones connect to circuits that send either “light” or “dark” signals to the brain, which
increases sensitivity to movement and the edges of objects. Nocturnal animals possess a pathway
through which rods connect to the same “dark” circuits used by cones, which allows them better per-
ception of edges, movement, and silhouettes in dim light.
Even the nuclei of the rod cells are adapted for night vision. In diurnal animals, the chromosomes in
the nucleus are densest around the edges, which means that any absorbed light is scattered around the
edges. In nocturnal animals, the densest material is in the center of the nucleus, effectively focusing all
of the available light in one area.
One can only guess at what nocturnal animals see. It’s likely to be shades of gray, sensitive to movement
but maybe lacking fine detail. Most nocturnal animals also have a highly developed sense of hearing, touch
(e.g., whiskers), or smell to complement their vision. One should not get the impression that an animal’s
night vision is perfect – even nocturnal animals aren’t active in the darkest hours of a moonless night.

There are two hard and fast rules for trail
building: never fill without retaining, and always
channel water off the surface of the trail.
Retaining walls are used to support turning
platforms on switchbacks and to shore up trail
edges. Trail builders prefer to make these walls
with large rocks, as they don’t rot and their
weight provides strength in the wall. The top of a
retaining wall must be lower than the trail tread
so that water will sheet across rather than gather
on the trail. Strategically placed grade reversals,
“nicks” (shaved down sections of a trail that are
canted to the outside) and rolling grade dips all
help to shed water from the trail. Good signage is
essential to keep riders on the trail. If riders cut
corners, they can slowly widen trails and make
them vulnerable to water erosion.
For mountain bikers, flow is everything. A good
trail hangs together as a well-connected whole,
with perfectly placed corners, well balanced
ascents and descents, and an overall unity that
helps to pull the rider along. On a well-built trail,
riders can relax and fully immerse themselves in
the experience of mountain biking. In the end, a
memorable mountain bike trail is a work of art.

“I’ve got some pellets here.”
“Here’s a run!”
he run was a path in the snow made by rabbits –
specifically, rare and imperiled New England cottontails.
The pellets? New Hampshire Fish and Game biologist
Heidi Holman was referring to small, rounded, brownish
rabbit droppings. Those telltale signs of habitation brought
smiles to the faces of Holman, U.S. Fish and Wildlife
Service endangered species biologist Anthony Tur, and Jenna
Bourne, an employee of Stonyfield Yogurt, in Londonderry,
New Hampshire, on whose land the group was walking on a
sunny late-February day.
The searchers tramped through a foot of snow. They picked
their way past clumps of six- and eight-foot-tall alder, aspen,
birch, and maple while judiciously avoiding concertina tangles
of multiflora rose. This was thicket habitat – a blend of shrubs
and young trees that provides the dense cover New England
cottontails need. Three years earlier, a timber harvest had
spurred the growth of that vegetation, and the local cottontails
responded by moving in. Wilderness it wasn’t: the 11-acre patch
wrapped around three sides of Stonyfield’s Yogurt Works, a
low gray building; planes roared overhead, headed for landings
at nearby Manchester Airport; and trucks beeped while backing
up at other light-industry plants nearby.
These days, biologists are happy to confirm the presence of
New England cottontails anywhere they can. Since the 1960s,
the species has lost an estimated 86 percent of its habitat, and its
range has contracted to five subpopulations separated from one
another by miles of mature forests, highways, shopping malls,
and housing developments. Its numbers have fallen so low that
this once-abundant regional rabbit is now being considered for
endangered or threatened status under the federal Endangered
Species Act.
In New Hampshire (where it’s been on the state endangered
list since 2008), as few as three dozen New England cottontails
may remain. Next door in Vermont, New England cottontails
have vanished – conservationists consider them extirpated,
though they once ranged across the state’s southern tier and
north through the Champlain and Connecticut River valleys.
Maine has 250 to 400 rabbits (state endangered since 2007), all
in the coastal southwest. A few New England cottontails may
be left in Rhode Island – or perhaps none. The Massachusetts
population numbers in the hundreds, mainly on Upper Cape Cod
and in the Berkshires. Connecticut may have a couple thousand
New England cottontails in its eastern and northwestern
sections, and a similar number may live in New York state, east
of the Hudson River and in the Taconics.

But wait – aren’t cottontails seen with fair frequency in
southern New England? Yes, but the rabbits hopping across golf
courses and nibbling suburban lawns are not New England’s
own. They’re eastern cottontails, as alien to the region as the
autumn olive, Asian honeysuckle, and multiflora rose that
have quietly taken over much of the shrubland that remains.
In times past, only New England cottontails existed in New
England. Folks called them coneys, brush rabbits, and woods
rabbits. They lived on abandoned farms that were reverting to
forest, and in areas where wildfires, windstorms, beaver dams,
springtime flooding and ice scouring, and heavy logging had
temporarily toppled, killed, or otherwise removed older trees so
that young trees and shrubs could come crowding back in.
All of those factors, except storms, have been blunted. Yester-
year’s farms are now mature woods stitched with stone walls.
Dams by the hundreds limit ice scouring and floods. We humans
have suppressed wildfires and beaver activities to protect lives and
property and have covered much of the land with development.
Heavy logging is almost nonexistent in southern New England,
much of which is cloaked with closed-canopy middle-aged and
older forest – a type of habitat that, although natural and needed
by some kinds of wildlife, does not offer enough low-growing
vegetation for New England cottontails or around 60 other
young-forest-dependent creatures, including woodcock, brown
thrashers, towhees, chestnut-sided and blue-winged warblers,
and box and wood turtles. The populations of all these animals
– identified by the states as “species of greatest conservation need”
– have been falling over the past 50 years as the amount of thicket
and young-forest acreage has steadily dwindled.
Two different rabbits
For the New England cottontail, there’s an extra odd twist:
During the first half of the twentieth century, state wildlife agen-
cies and private hunting clubs released thousands of eastern
cottontails (most of them from Kansas, Missouri, and Texas)
to boost hunting opportunities. Eastern cottontails don’t pop
down holes as readily as New England cottontails do, which let
hunters enjoy longer chases with their rabbit hounds and upped
their chances of bagging a bunny. Those imported eastern cot-
tontails caught on, and today they greatly outnumber the native
rabbits across most of southern New England.
The New England cottontail (Sylvilagus transitionalis) and
the eastern cottontail (S. floridanus) do not interbreed, or if they
do, offspring apparently don’t survive. An adult eastern cotton-
tail is a bit larger than a New England, weighing three pounds
versus about 2.2 pounds. Otherwise they look similar, with a
mottled brown-and-black pelt and a white powder-puff tail.
Most New England cottontails have a small black spot on the
forehead, whereas about half of all easterns have a white spot in
the same place. The New England’s ears are slightly shorter than
the eastern’s and have a thin line of black fur along the outer
edge. Skull shape differs between the species as well.
Most of what we know about cottontails in New England
comes from research conducted by John Litvaitis, a professor
of wildlife at the University of New Hampshire. Beginning in
the 1990s, Litvaitis and his graduate students went looking
for rabbits and their habitat all over southern New England.
Their field work galvanized conservationists and helped put the
New England cottontail on the shortlist for potential federal
endangered status. The researchers also developed a protocol
for extracting DNA from rabbit pellets, revealing whether the
droppings come from New England or eastern cottontails, which
lets biologists chart where the former remain. (For example,
ongoing pellet studies have revealed that all of the cottontails
around the Stonyfield Yogurt plant are New Englands.)
The researchers also studied how the two kinds of cotton-
tails interact. After putting both types of rabbits in a thicket
enclosed by wire fencing, they concluded that the larger eastern
cottontail does not dominate or displace the smaller New England
cottontail from its habitat. “The only detectable difference
between them,” Litvaitis wrote in a 2002 article in New Hampshire Wildlife Journal, “was that eastern cottontails were
often observed in areas with little understory cover.”
The scientists built another pen and installed feeders with
electronic sensors, which allowed them to monitor when a rabbit
was present. They found that eastern cottontails traveled farther
from protective cover to get food. “Our farthest feeder was
about 60 feet from cover,” wrote Litvaitis, “a long distance for

a rabbit trying to avoid a hungry fox or owl.” Although eastern
cottontails would chow down at those feeders, “New England
cottontails were very reluctant to visit [them] unless they started
to lose weight and were clearly very hungry.”
When the researchers sent a life-sized owl decoy gliding along
a wire suspended over caged rabbits, eastern cottontails spotted
the approaching decoy when it was 70 feet away. New England
cottontails didn’t see the owl until it was only 30 feet away.
Why, the scientists wondered, could an eastern cottontail spy
a predator so much farther off than could its Yankee cousin? The
answer turned out to be fairly simple: the eyes of Eastern cotton-
tails are 50 percent larger than those of New England cottontails,
giving them better long-range vision. Likely, this more-acute
vision developed because the eastern cottontail evolved in open
plains habitats, where it needed to detect danger at a distance. In
contrast, the New England cottontail evolved in shrublands, such
as mountain laurel and scrub oak thickets, and in young forests
created by fires, floods, hurricanes, and beaver work; in such dense
settings, a woods rabbit didn’t need to spot far-off predators.
Today, their long-range vision lets eastern cottontails use the
small patches of thicket habitat that remain in southern New
England: an acre of invasive shrubs behind a strip mall, a briar
patch bordering a gravel pit, a hedge in somebody’s backyard.
From such tatters of cover, eastern cottontails creep out to feed
on grasses, clover, plantain, and other low herbaceous plants in
summer, and on woody vegetation in late fall, winter, and early
spring – and are better able to dash back to cover if a predator
threatens. “Because staying close to cover is probably the best
strategy in forest habitats,” Litvaitis concluded, “New England
cottontails suffer disproportionately when cover shrinks.”
In the wild, the fate of almost every rabbit is to be killed
and eaten by a predator. The researchers identified red foxes
and coyotes as the most common causes of death among 75
radio-collared free-ranging New England cottontails that they
monitored in southern New Hampshire. Cottontails are also
preyed on by fishers, mink, weasels, hawks, owls, large snakes,
bobcats, domestic cats and dogs, and humans. Skunks and rac-
coons raid the natal nests – made from grasses and from fur that
the mother-to-be plucks from her own coat. Another Litvaitis
study showed that the variety and number of predators goes up
in fragmented, human-modified landscapes such as those of
southern New England.
Based on years of study, Litvaitis suggested that for New
England cottontails to occupy a given site indefinitely, they need
a minimum of 20 interconnected acres of good-quality thicket.
Winter is a tough time for rabbits: Instead of feeding on (and
staying hidden in) the abundant greenery of summer, they skulk
in thick shrubs or underground burrows by day, then venture
out at night to nibble on the bark, twigs, and buds of woody
plants, food that is much less nourishing than summer fare. In

winter, the protective cover is at its thinnest, and if snow blan-
kets the ground for long periods, the rabbits stand out sharply
against the white background. (Unlike the larger snowshoe
hare, another New England native, neither the New England
cottontail nor the eastern cottontail takes on a protective white
coat in winter.) Litvaitis found that in habitat patches 12 acres
and larger, about 7 out of 10 New England cottontails will make
it through winter. But once a patch gets smaller than about six
acres, winter mortality can soar to 66 percent. And if the habitat
continues to shrink, its resident population will wink out.
Helping nature along
The recently improved habitat patch at Stonyfield Yogurt cov-
ers 11 acres, which implied that the “dozen” rabbits thought to
inhabit the tract might have dwindled to eight by that February
day when Tur, Holman, and their colleagues went looking for
cottontail sign. Those theoretical eight bunnies would likely
repopulate the patch during the year to come. Offsetting the
fact that cottontails are food to so many predators is their great
reproductive capacity: A female can have three to four lit-
ters per year, with an average of three to four young per litter.
Cottontails are born blind, but they develop quickly. A rabbit’s
conception through its birth, weaning, and independence takes
only 60 days. Females born early in the year may produce a litter
of their own that same summer.
The previous autumn, Holman had live-trapped and removed
two New England cottontails from the Stonyfield patch. The
improved habitat had helped boost bunny numbers during the
breeding season, so the biologists felt they could safely take a
couple of individual rabbits without harming the local popu-
lation. The two rabbits went to Roger Williams Park Zoo in
Providence, Rhode Island, to become part of a captive breeding
program that, coupled with habitat-creation efforts gearing up
all over the species’ range, aims to save Sylvilagus transitionalis from extinction.
Since 2010, captive-breeding specialists at the zoo have been
perfecting housing, feeding, and breeding protocols. Their goal
is to produce the maximum number of healthy brush rabbits
that can go back into the wild, both to boost the numbers and
genetic diversity of existing populations and to start new popu-
lations in places where conservationists are making habitat.
As of March 2013, 17 female and 10 male New England cot-
tontails were housed at the zoo, with the year’s breeding just get-
ting underway. So far, 15 captive-bred rabbits have been released
on brush-covered Patience Island, a 210-acre uninhabited island
in Narragansett Bay. This year biologists hope to confirm natu-
ral reproduction there; if the island population thrives, it could
become a source for restocking other areas. Conservationists
have also built two hardening pens, at Ninigret National Wildlife
Refuge in Rhode Island and Great Bay National Wildlife Refuge
in New Hampshire. Young captive-bred rabbits will spend a
month in those one-acre, predator-proof enclosures learning
how to hide in cover and feed on native vegetation; then it’s off

to the real world, red in tooth and claw.
“We’d like to have a hundred or more animals come out of
the zoo in 2013,” Tur said. “The effectiveness of captive breeding
will be measured by whether or not captive-bred individuals can
go back into the wild, reproduce, and bear young.”
Captive breeding will likely be a key aspect of restoring the
New England cottontail. But if there isn’t enough habitat out
there, the overall effort will fail.
Habitat is the key
Making rabbit habitat is the goal of a partnership formed
in 2007 between the five states that still have New England
cottontails, the U.S. Fish and Wildlife Service, and the U.S.
Department of Agriculture’s Natural Resources Conservation
Service (NRCS). A Conservation Strategy for the New England Cottontail, written by Tur and Steven Fuller, a scientist who
coordinates the rangewide New England Cottontail Initiative,
came out in November 2012. (It can be downloaded at www.
newenglandcottontail.org.) Developed with input from state
wildlife biologists, the document maps 47 focus areas where,
between 2012 and 2030, conservationists plan to create more
than 50,000 acres of habitat to support 28,100 New England cot-
tontails – enough, scientists believe, to save the species.
How to make that habitat? Potential management techniques
include even-aged timber harvests (both clearcuts and shelter-
wood cuts); noncommercial timber harvesting (cutting down
trees that are not large enough to provide a financial return);
mowing or mulching old, straggling shrubs; and conducting
controlled burns. All of those methods mimic the kinds of cata-
strophic natural events that once operated freely to make early
-successional habitat. All remove the forest or shrub canopy and
let sunlight reach the ground, which spurs the growth of low,
thick vegetation. Such management practices must be ongoing,
because shrubland and young forest generally remain good rab-
bit habitat for only about 20 years. After that, their leafy crowns
knit back together and exclude sunlight, and groundcover once
again gets sparse.
A major component in a New England cottontail comeback is
the NRCS’s Wildlife Habitat Incentive Program (WHIP). WHIP
funding has helped more than 20 private landowners make over
350 acres of potential cottontail habitat in New Hampshire,
and this year another 10 landowners will begin projects on an
additional 150 to 200 acres. WHIP is also enabling private-land
projects in the other New England cottontail states, particularly
in areas next to habitats, such as scrub wetlands, that support
existing cottontail populations. Recently the NRCS began a
nationwide Working Lands for Wildlife (WLFW) initiative that
features the New England cottontail as one of seven wild ani-
mals for which the agency will help farmers and forest landown-
ers make critically important habitat. In 2012, WLFW issued
contracts pledging to pay 44 landowners $1.5 million to make
New England cottontail habitat on more than 1,300 acres. States,
other federal agencies, and organizations such as the National
Fish and Wildlife Foundation have committed several million
dollars to New England cottontail recovery as well.
Another New Hampshire project illustrates what can be done
on public land – in this case, the 428-acre Bellamy River Wildlife
Management Area near Dover. In 2011, loggers harvested low-
quality white pines and hardwoods with a 30-acre clearcut. The
following spring, saplings began spring-
ing up from the root systems and
stumps of the logged-off hardwoods.
Over the next several growing sea-
sons the clearcut should metamor-
phose into a jungle of dense trees
and shrubs. The clearcut is next
to cover where New England cot-
tontails live, so the rabbits ought to
jump right in. Conservationists
have also been planting
native shrubs such

as dogwood, hazelnut, and arrowwood. “We estimate there are
about 200 acres of potential New England cottontail habitat on
the wildlife management area,” said Jim Oehler, a biologist with
New Hampshire Fish and Game. “Over time, we hope to keep 75
percent of that acreage in suitably dense bunny habitat.”
Other conservation efforts in the Granite State include agree-
ments with utility companies to lessen the frequency with which
they mow power-line and gas-line corridors; the companies
will simply remove trees as they get too big. “The idea is to
continuously maintain thicket cover,” Holman said. Biologists
hope New England cottontails will use the brushy corridors
to disperse from one population to another, occupying habitat
patches as they are renewed or created, and maintaining genetic
flow within the species.
In Connecticut, biologists and foresters with the state’s
Department of Energy and Environmental Protection have cre-
ated sizable habitat patches on four state properties and plan work
on six more state-owned tracts. Clustered around those sites are
projects on private lands, like the one on aptly named Cottontail
Farm near the town of Scotland. There, landowner Tom McAvoy
is improving shrub habitat in five fields by rooting out older
invasive shrubs, such as autumn olive, and replanting with native
shrubs that offer better food and cover. A 10-acre timber harvest
took place in February 2013; soon, regrowing oaks, maples, and
hickories, along with a dense blueberry understory, will add to
the habitat mix. “I look at this as a legacy project, one that my
sons will be part of in the future,” said McAvoy.
In addition to WHIP funding, McAvoy received help through
the U.S. Fish and Wildlife Service’s Partners for Fish and Wildlife
program. Ted Kendziora, a biologist working out of the Service’s
New England field office, supplied planning, technical advice,
and funding, then supervised the private contractors who did
the actual habitat-enhancement work.
Kendziora is helping landowners make habitat in every state
across the New England cottontail’s range. One area with a good
population of New England cottontails is Upper Cape Cod, where
more than 400 acres of fresh rabbit habitat have been created by the
Town of Mashpee, Orenda Wildlife Land Trust, the Wampanoag
Mashpee Native American Tribe, and the Trustees of Reservations,
along with the state of Massachusetts and the U.S. Fish and
Wildlife Service’s Eastern Massachusetts Refuge Complex. Many
of the tracts abut or lie close to each other. And only a mile down
the road is the Massachusetts Military Reserve at Camp Edwards,
where wildlife biologists have conducted controlled burns on
more than 1,500 acres of coastal scrub since the 1990s and where
a robust New England cottontail population remains. The use of
fire in this sandy coastal environment removes dead vegetation
and makes it less likely that large, out-of-control wildfires will flare
up in the future. Prescribed burning also renews scrub oak, a low-
growing, fire-evolved oak that’s more of a shrub than a tree and,
when young and dense, offers great rabbit habitat.
So while the situation looks bleak in some parts of its range,
conservationists are optimistic that they can reverse the popula-
tion drop the New England cottontail has taken over the last
half-century. According to the Conservation Strategy for the New England Cottontail, around 145,000 acres of public land are
highly suitable for turning into woods-rabbit habitat. Focusing
management on public tracts would make for substantial cost
savings compared to creating habitat on private parcels and
would reduce the number of management actions needed, along
with their accompanying planning and oversight. It would also
increase the opportunity to use cost-effective controlled burn-
ing as a management tool, plus generate income – and jobs
– from timber products.
To make the habitat that the New England cottontail needs,
conservationists will have to change the public’s perception
of management activities such as burning brush thickets or
clearcutting generous-sized forest tracts – not an easy task in
heavily wooded southern New England, where many people
shudder at the idea of cutting down even a single tree and
where state and local regulations often severely limit the extent
and siting of logging jobs.
As an endangered species biologist, Anthony Tur works with
many animals, from the American burying beetle to Blanding’s
turtle to the mountaintop-dwelling Bicknell’s thrush. “The New
England cottontail is an important part of the wildlife legacy
and biodiversity of our region,” he said. “All species have an
inherent value, and all of them have a place on the landscape.
If humans are the reason for an animal being in trouble – and
clearly we’re part of the problem the New England cottontail is
facing today – then we have a moral responsibility to work hard
to keep that animal around.
“In particular, the New England cottontail is a good barom-
eter of the health of a certain kind of habitat: dense thicket veg-
etation. When we make habitat for New England cottontails, we
help out many other kinds of wildlife. I think we’ll be successful
in this effort. Cottontails are prolific animals. If we supply the
habitat, the rabbits will do the rest.”

At Work Solving Crimes with Wood Sleuth Richard JagelsIf Richard Jagels had a casebook like Sherlock Holmes, the titles
might be: “The Case of the Twig in the Mirror”, “The Case of the
Killer Ship Mast”, “The Case of the Doubtful Dowels”.
Jagels is a wood forensics consultant – a wood sleuth. He
can take tiny samples of wood, ancient or recently cut, put
them under a microscope, and, using his vast knowledge of
wood anatomy and the resources of his impressive library, tell
you whether the sample is Philippine mahogany or California
madrone, red spruce or red pine, eucalyptus or elm.
Jagels would be the first to tell you his investigations don’t
have the glamour of a CSI episode and that he’s not Sherlock
Holmes. But, like the enduring fictional detective, he still gets a
thrill when the game’s afoot. “I enjoy doing the analysis, trying
to figure out the species,” he said, confessing that, “I don’t enjoy
sitting in court testifying.”
Balding, glasses, mustache, worn jeans … Jagels looks the
picture of a retired forestry professor, which is what he is. He
built a side career as a wood forensics consultant while working
at his full-time job in the University of Maine’s School of Forest
Resources, where for three decades he taught courses in the
functional structure of woody plants, wood identification, and
plant microtechnique (a lab course on the ways to prepare plant
tissue for microscopic analysis). As a scientist, he researched the
biomechanics of tree stems and how trees react to stress, such as
the effects of acid fog on coastal conifers. While he retired from
teaching a couple of years ago, he still does forensics and other
consulting work.
Today, Jagels leans back in the chair in his office, a cozy
upstairs space overlooking the brown and swollen Penobscot
River as it muscles past the historic town of Winterport, Maine.
Two flat-panel computer screens perch on the desk. Another
desk holds a microscope, razor blades, and other paraphernalia
for preparing specimens. Bookshelves cradle seemingly every
book ever written on wood and wood identification. Jagels leans
over and pulls out the bottom drawer of a filing cabinet to reveal
neatly labeled folders, more than 30 years worth of cases.
Jagels grew up in White Plains, New York, and went to
SUNY-ESF Syracuse, where he majored in wood anatomy, pri-
marily, he admits, because “there were more electives available.”
He went on to earn a master’s degree in forest pathology, then a
doctorate in botany from the University of Illinois.
Following school, he bounced around for a while – with
stints at various jobs at the University of Alberta, the University
of Vermont, Dartmouth College, Louisiana State, and the
Winterthur Museum in Delaware, where he worked on wood
identification projects – before landing at UMaine in 1979.
Between the University of Vermont and Dartmouth, he made
ends meet doing construction and some freelance writing. He
dialed up WoodenBoat magazine to pitch an article about an
Adirondack guide boat he was restoring and ended up landing
a gig to write a column on wood technology. He’s been doing
it ever since. And it’s that column that brings him a lot of his
forensic cases.
“It just sort of built itself as a sideline,” Jagels said. “I’ve never
advertised. It’s all been word of mouth. I’ve never pushed it.
After all, I already had a full-time job.” Still, he’s worked for the
Maine State Police, engineering firms, museums, private parties,
and lawyers. About a third of the 100 or so cases he’s worked on
qualified as forensics work. He’s working on one now, but he’s
not at liberty to divulge any details. Still, he can talk about the
finished ones.
To really understand how Jagels does what he does, you’d
probably have to take a course in wood anatomy. The way he

In The Case of the
Doubtful Dowels, Jagels
was contacted by a west-
ern Maine dowel mill
to see if he could fig-
ure out a way to deter-
mine whether dowels
had been sanded. There
was money riding on
the question: Canadian
customs officers claimed
the company’s dowels
were sanded and thus
were a finished product
subject to higher tariffs. After trying various stains and dyes,
Jagels hit upon the perfect method: rubbing a pencil over it.
“After rubbing along the axis of the dowel with a No. 2 pencil, if
darker rings show up that encircle the dowel, this means it has
not been sanded; in other words, you can see the traces of the
cutters used to shape the dowel. Sanded dowels will show only
the pencil marks that run parallel to the grain,” said Jagels. “A
customs officer can do it in a few seconds.”
Not all of Jagels’ forensic work has been in the interest of jus-
tice or commerce. Some of it has been in the interest of science.
About ten years ago, he was one of a team of scientists who
trekked to the Arctic Ocean’s Axel Heiberg Island to examine
the remains of a huge fossilized forest. Many of the trees turned
out to be dawn redwoods (Metasequoia glyptostroboides), an
ancient species that grew when the dinosaurs roamed and was
thought to be extinct until a small grove was found growing in a
remote area in China in the 1940s. The trees in the Axel Heiberg
forest lived 35 to 40 million years ago. Jagels still has the speci-
mens, looking dark and very, very old.
Jagels keeps on with the forensic work, getting a couple of
cases a year, but fewer criminal cases come his way now – DNA
evidence is more definitive these days, he explained.
He sees the entire realm of wood science and wood anatomy
slowly disappearing. These days, most forestry schools don’t
even have wood science programs, he said. Not enough students
want to take it, a result, Jagels believes, of our changing rela-
tionship with wood. Though we continue to use wood – huge
volumes of it – we tend not to use it as lumber. What’s most
furniture made of these days? Composites. Young people aren’t
even interested in antique furniture, he said.
These days, Jagels devotes more of his time and talents to
conservation. He is a founding member and board director
of GreenWood, a nonprofit that trains artisans in developing
countries to make and market wood products and to manage
their forests sustainably.
Joe Rankin is a writer, beekeeper, market gardener, and orchardist. He lives in central
Maine.
explains it, identifying a piece of wood involves looking at
how its cells are organized, understanding how the cell walls
are sculpted, and considering whether there are any inclusions
present. “Occasionally one or a few features define a species,
but more often a combination of features is needed to separate
woods,” he said. For example, if there is spiral thickening of the
longitudinal tracheids, the water-carrying cells that run up and
down through the stem of a tree, it’s probably a Douglas fir.
But it’s a trait shared with the yew family. “Always exceptions,”
said Jagels. “A more complicated scenario would be whether a
conifer has ray tracheids or not, and if so, are the tracheids den-
tate, and if so, are the dentations short or do they extend across
the cell, and if so, what kind of ray crossing pits are present, et
cetera, et cetera,” Jagels added. (Now you see why that course in
wood anatomy might come in handy.)
In a 1988 case, he identified pieces of a twig and leaf material
found in the side-view mirror of a murder suspect’s car as bal-
sam fir and linked the wood to a damaged tree at the site where
the victim’s partially clad body was found, dumped off a tote
road in Hermon. In 1990, he matched a white pine chip found
with a young rape and murder victim’s body to similar chips
found in the car of the prime suspect – a woodworker. Both
suspects were convicted, based partly on his evidence.
Criminal cases involving wood are few and far between.
More often Jagels’ expertise is sought by lawyers in civil cases,
like The Case of the Victory Chimes. The professor was hired
by a firm pursuing a wrongful-death lawsuit against the owner
of the Victory Chimes, the iconic three-masted schooner later
immortalized on the Maine state quarter. A rigger had died
when a mast snapped off. The mast had been deteriorating, but
rather than replacing it, the owners had it repaired using a metal
collar and epoxy, said Jagels. He showed that the repairs made
a serious problem worse by trapping moisture and accelerating
the rot’s movement from the heart of the mast to the outside.

Adaptations for living on the alpine edge
Story by Meghan Oliver / Photos by Doug Weihrauch
nyone who’s made his or her way up a mountain is familiar with the some-
times startling transformation of the landscape, from leafy hardwood
stands to thick and prickly green cathedrals of red spruce and balsam
fir. Above 3,000 feet, the soil thins and the trees – called krummholz
in mountaineering parlance – become noticeably shorter, bent over,
and stunted by endless winds. It’s hard to believe anything can live
in such an unforgiving environment, but if you’re lucky, as you
crest the mountain’s peak, you may observe a low-lying sweep of
colors amid the rocky cover, courtesy of flowering alpine plants.
In the Northeast, alpine plants grow in a specialized habitat of dry and rocky soil,
constant winds, and cold temperatures, explained Doug Weihrauch, staff ecologist for the
Appalachian Mountain Club. Alpine zones only comprise about 35 square kilometers total
in the Northeast, making them just a tiny part of the region’s mountainous landscape.
But despite their relatively small presence, alpine wildflowers and other plants put
on a remarkable (though short-lived) show each spring and summer. “When you’re
hiking above treeline, you’re hiking into New England’s vegetation past,” Weihrauch
said, referring to the tundra vegetation – the lichen, mosses, and low-growing plants
– that were the first to creep in as glaciers receded.
Alpine flowers bloom in waves, with the first flowers occurring as early as May; look
then for blooms of diapensia, alpine azalea, and Lapland rosebay. June brings – among
others – the rare dwarf cinquefoil, the white blooms of moss plant, alpine bluets, and
Labrador tea, the flowers of small cranberry, and the purple alpine marsh violet. In July,
keep your eyes peeled for the Boott’s rattlesnake-root, arnica, alpine speedwell, harebell,
and the miniscule flowers of eyebright. In August, while alpine aster and alpine gold-
enrod are in blossom, look for the fruits of alpine plants in the heath family, including
mountain cranberry, small cranberry, bilberry, bearberry, and others.
We invite readers to give alpine flowers a good look this summer – an appreciative
look. From a distance, diapensia might just look like a few splotches of white around
some gray rocks. But take a closer look at its waxy leaves and miniature size; marvel
at the fact that these delicate-looking blooms can survive in the most punishing wind-
exposed sites. There’s a whole new world of plants awaiting your admiration (and
respect) up in the alpine zone.

Adaptations for Surviving Above the
TimberlineLow to the groundMost alpine plants are only 1 or 2 inches tall, and being low to the
ground has a number of advantages. The plants’ diminutive size
allows them to stay out of the wind, and in winter, being small means
protection under a thick snowpack. In summer, the soil temperature
in alpine areas may be as much as 15 degrees higher than air
temperature just centimeters above the surface.
Cushions and matsSome alpine plants, such as diapensia and alpine azalea, grow into
a cushion or thick mat. A rounded cushion shape allows wind to fly
smoothly over the plants without tussling delicate leaves. A thick mat
will absorb and retain heat.
Evergreen foliage Evergreen leaves help alpine plants get a jumpstart on the growing
season; they can start photosynthesizing as soon as the temperature
rises above freezing.
Red leavesThe leaves of some plants, such as diapensia, turn a deep reddish-
purple in the non-growing season. The color is caused by anthocyanin,
which absorbs ultraviolet rays and converts them into heat energy,
which warms the plant earlier in the growing season.
Thick, waxy leaves Thick foliage helps alpine plants deal with excessively well-drained soil
in summer and the ever-present drying winds. “Plants need to keep
stomates open to allow photosynthesis and respiration, but this also
lets out moisture, especially in windy conditions,” Weihrauch explained.
Thick leaves help in two ways. “They are less likely to be torn or
damaged by high winds, which are frequent above treeline, and [their
thickness] reduces the surface area exposed to desiccating winds.”
Many of the leaves, such as those of mountain cranberry, produce a
waxy cuticle to aid in water retention.
Fuzzy, curled leavesEven for alpine plants that grow in areas with adequate soil moisture,
desiccation can be a battle for at least part of the year. Fuzzy leaves can
help retain moisture by “combing moisture out of clouds,” Weihrauch
said, and retaining that moisture near the leaf surface when the air dries
out. For a plant like Labrador tea, hairs on the undersides of the leaves
protect the stomates, which, when open for gas exchange, lose water.
Moisture loss through the leaves increases under high winds and when
there is a big differential between moisture levels within the leaf and
the surrounding air. A barrier of moist hairs on the underside lessens
that differential. Labrador tea also has leaf margins that curl under as
another way to lessen wind exposure and the moisture loss that would
occur in a more exposed leaf surface.
Slow growthSlow growth keeps these plants from growing unnecessarily high, which
is dangerous in the alpine zone. Extra height means more exposure to
winds and the risk of becoming taller than the snowpack. “In a good year,
they’re lucky to put on a few inches of growth,” Weihrauch said. He noted
that some plants the size of a quarter may be 25-50 years old.

Where to Find Them Lace up your boots and pack an extra layer: it’s time to ascend
the great alpine peaks of the Northeast in search of alpine flora.
Weihrauch noted that any hiker in the alpine zone should stick to
trails or step or skip from rock to rock to avoid walking on the plants,
which can die from being trampled. “They haven’t evolved to have a
bunch of people hiking all over them,” Weihrauch said with a laugh.

The New England
settlement story is
a familiar narrative.
We all know the tale:
farms hacked out
of daunting woods
in the eighteenth
century, rolling
Agricultural lands in
the nineteenth century,
and abandoned fields
reverting to forest in
the twentieth century.
There’s only one
problem: That’s not
what happened
in Maine.
Euro-Americans colonized the Maine
coast in the 1600s and early 1700s, but
much of this occupation was repulsed by
Abenaki tribes. After the Revolutionary
War, a larger wave of settlers pushed inland,
quilting southern and central Maine with
farms and in the process clearing more
than three million acres of forest. But after
the Civil War, immigration into the state
slowed to a trickle, and many people left
their Maine farms for better land in the
Midwest, or the industrializing cities of
the Northeast. As a result, settlers never
reached most of the northern half of the
state, leaving about 14-15 million acres of
forest intact. In short, the business plan to
settle the state never materialized.
There is no state like Maine in the
eastern U.S. where such a large chunk of
contiguous land has remained continu-
ously forested since pre-settlement times.
It’s tempting to look for similarities with
the western U.S., where vast forests were
never cleared. Most of those lands, how-
ever, are managed by the federal govern-
ment. Most of the Maine Woods are pri-
vately owned, and that has led to a very
different kind of relationship between
people and forests. Maine, in other words,
has carried out its own unique, long-term
experiment in land use.This article is adapted from the authors’ 2012 book, The Changing Nature of the Maine Woods, which explores the following topics in greater depth. Sources for the article can be found there.

What are the consequences of this 400-year experiment?
Does today’s forest look like the forest before European settle-
ment? Have the characters in the story – the plants and animals
and other species – changed in any appreciable way?
Uncovering the past
Historical ecologists have spent decades reconstructing what
pre-settlement forests were like in Maine. It’s challenging work,
as we’re talking about ecosystems that existed 200 to 600 years
ago, differed widely across the state, and were never static. No
single approach or type of data will suffice; we must rely on
multiple lines of evidence that operate at different geographic
scales and combine history, biogeography, archaeology, survey-
ing, natural history, and ecology.
Our first clues come from early explorers who wrote about
coastal forests. The earliest of these observations, in the 1500s, are
not especially revelatory, such as this description from Giovanni
da Verrazano in 1524: “nothing extraordinary except vast forests.”
When the early settlers did get specific, their tree naming was
often rudimentary and flexible. The early usage of “fir,” “spruce,” or
“cypress,” for example, could have referred to any conifer.
But by the 1600s, some explorer journals record detailed
observations, such as the following description of the Camden
Hills from the 1605 Waymouth voyage:
passed over very good ground, pleasant and fertile, fit for
pasture, for the space of some three miles having but little
wood, that Oke like stands left in our pastures in England,
good and great, fit timber for any use. Some small birch,
Hazle and Brake . . . Upon the hills grow notable high
timber trees, masts for ships of 400 tun.
A second source of clues comes from land surveys, from
which one can tease data related to topography, water drain-
age, forests, natural disturbance, and specific trees. Surveyors
used witness trees to mark boundaries, and the frequency of
these trees in survey records provides a reliable estimate of the
species composition of the forest at that time. Charles Cogbill
has collated presettlement land survey records and recorded
23,490 witness trees in what is now Maine. This includes some
36 species (or closely related groups of species) in 180 towns.
For example, a 1789 survey by Ephraim Ballard in west-central
Maine noted eastern hemlock, American beech, northern white
cedar, birches, maples, northern red oak, and American bass-
wood. A survey in the far northern tip of Maine in Aroostook
Township in 1845 describes a very different forest: lots of fir and
spruce, some hardwoods, and balm of Gilead (balsam poplar).
But the human record is only part of the story. Paleoecologists
use preserved pollen, macrofossils, charcoal, and insect remains
to reconstruct environments of the past. As the glaciers receded,
Maine was dotted with lakes and ponds onto which all manner
of wind-blown flotsam – pollen, seeds, cones, leaves of plants,
even bits of charcoal from fires – blew and sank to the bot-
tom. Lakes slowly filled with organic matter, some remaining
as bodies of water, others developing into bogs or fens. Low
oxygen levels slowed decomposition in these sediments, and the
embedded detritus was preserved, layer upon layer.
Using radiocarbon dating on these bog cores (see sidebar,
page 43), we’ve been able to reconstruct a pollen chronology
that records more than 14,000 years of forest changes in Maine
– from tundra to spruce-fir to a drier pine-birch-oak forest to
mixed hardwoods and, finally, to the mixed hardwoods and
softwoods the explorers found.
Historical records and 14,000-year-old sediment samples are
intriguing, but we can’t forget to simply go out into the woods
and see what’s there. Presumably, old growth forests resemble
presettlement forests and contain clues about forest composi-
tion, structure, and the roles of various disturbances in shaping
them. Maine has scarcely any old growth remaining – mostly
tiny stands (or stunted vegetation on high mountains) that
have survived because of an idiosyncratic history of ownership,
condition, or location. Fortunately, The Nature Conservancy’s
Big Reed Forest Reserve protects a singular Maine old growth
landscape of 5,000 acres.
By analyzing cores from 6,909 trees (63 dating from before
1750, the oldest prior to 1555), Alan White and his graduate stu-
dents were able to reconstruct a record of how much the Big Reed
forest has been naturally disturbed by fire, wind, ice, and other
natural phenomena. They found that the average stand distur-
bance rate is only about 9 to 12 percent per decade and projected
that a major disturbance (over 50 percent disturbed) would occur
only once every 1,100 years. Big Reed Forest Reserve also provides
a glimpse of the rich species diversity (26 different tree species!)
that the unmanaged presettlement forest would have supported.
No one line of evidence is sufficient to reconstruct the
presettlement Maine Woods, as each has advantages but also
weaknesses: only the witness tree data provide a nearly com-
prehensive geographic view; only the paleoecology studies
reveal changes over relatively long time periods; only Big Reed’s
old-growth landscape offers details about forest dynamics and
allows us to see and measure a forest that resembles those of
presettlement times. Taken together, however, the lines of evi-
dence reveal a picture of what the presettlement forest looked
like, how it operated, and how it varied across the landscape.
Maine forests then and now
So what do we find when we compare the forest of today with
the forest first encountered by settlers in the seventeenth cen-
tury? Remarkably, Maine’s forest area today is about the same
as it was four centuries ago. Maine is 21.3 million acres (19.8
million is land). In 1600, 18.2 million acres were forest; today’s
forest covers 17.7 million acres.
The major forest regions have also been largely stable since
presettlement times. Cogbill’s analysis of witness trees reveals
four major forest zones before European settlement: a south-
western oak-pine district (with some outliers eastward along the
coast); a west-central province of northern hardwood forest, with
beech as the most abundant species; a northern zone of spruces,
fir, northern white cedar, yellow birch, and lesser amounts of
other northern hardwoods; and a coastal area east of Casco Bay,

This graph shows the age-class difference between pre-settlement
forest estimates and data from 1995. The majority of the trees in
the Maine Woods today are between 10 and 75 years old; 400
years ago, most were between 150 and 300 years old, and almost
30 percent were older than 300 years.

largely of spruce and hemlock. These zones are widely recogniz-
able in modern forests and are the basis of most forested land
classifications in the state. Despite considerable change in cli-
mate, land use, and many other environmental factors, the forest
regions and transition zones have been remarkably stable.
This is not to say that the distributions of all species have
been static. The Carolina wren, northern cardinal, Virginia
opossum, and less welcome species such as ticks and invasive
plants have all migrated north over the past century. If we widen
the focus to all of New England, the list of northward traveling
species is large and taxonomically diverse, with frequent new
Past Worlds in a Grain of Pollen
A few years back I found myself standing in the middle of a black spruce bog
on the Phippsburg peninsula with Andrea Nurse, from the University of Maine’s
Climate Change Institute, and three research assistants. We were there to col-
lect a time capsule from the wet earth.
Andrea and student researcher Tommy Hannington stood a long, metal peat
corer on its pointy end, attached a T-bar handle, and began pushing it into the
sediment. The top few inches corresponded to recent decades of secondary
forest; the next few feet brought us through a couple centuries of farmland
now long abandoned, back to the mixed oak and spruce forest at the begin-
ning of European settlement. When we’d filled the borer’s three-foot chamber
we gave it a heave-ho and it rose with a great sucking sound. We emptied
the four-inch-diameter cylinder of organic material, added an extension, and
resumed our process.
Four, five, six feet into the past: hemlock and spruce, then hemlock is gone,
replaced by oak, beech, and birch, then hemlock again before it disappears
for good, replaced by white pine and oak. Twelve feet down it’s just spruce
and tundra plants, at which point the sediment resists. “We’ve hit bottom,”
says Andrea, breathlessly. We extract the borer and lay out this bottom core. It
looks different from previous ones – more solid, with little identifiable organic
matter. At the top is a dark smooth substance, plant matter that has been
transformed by compaction and the downward oozing of humic acid. Below
that is grayish clay, and finally seashells. As we’d expected, Phippsburg was
under the ocean just after the ice melted, but the 14,000-year-old ocean life
is still wondrous to see. — ANDREW BARTON
A peat core sample
reports. Many of these migrations appear to be connected to the
warming climate of the Northeast.
Given that Maine is already a warmer place than it was a
half-century ago, why haven’t tree species responded in some
conspicuous way? Part of the explanation is obvious: they don’t
have feet or wings with which to get up and go; their migration
depends on an annual march of seeds in whatever direction is
favorable. But trees differ from many other types of organisms
in another important way. Once established, trees tend to be
tolerant of all manner of assaults from the environment. They
also live for a long time, and so have an intrinsic inertia that may
well slow their response to climate change.
Despite the similarities in forest cover and geography, the
modern Maine Woods do differ from presettlement forest in
fundamental ways. A visitor from the seventeenth century would
find many familiar organisms, but key species, such as the gray
wolf, mountain lion, and caribou, are missing. The loss of two
top predators has likely profoundly altered food webs in Maine
forests, although the extent of these impacts is poorly known.
Many species of fauna and flora have immigrated to Maine,
and they predominate in some sites. A recent assessment of
Maine’s biodiversity found that about one-third of the 2,107
wild plant species in the state are exotics. Some of these will
be very familiar: purple loosestrife, Japanese knotweed, com-
mon buckthorn, Oriental bittersweet. But others – lupine, black
locust, and apple trees, for example – have become such an inte-
gral part of the Maine landscape that most people would be sur-
prised to learn of their nonnative status. This goes for animals,
as well, especially birds. European starlings, pigeons, and house
sparrows – all abundant in Maine – are European species.
There is circumstantial evidence that some forest-dependent
herbs, mosses, and lichens have become rare as a result of cen-
turies of land clearing and harvesting. Modern Maine forests
also tend to be lacking in large-diameter classes of dead organic
matter, such as snags, cavity trees, and logs, which provide habi-
tat for vertebrates, invertebrates, bryophytes, lichens, and fungi,
and supply nutrients to plants and other organisms. Whether
other presettlement species, especially inconspicuous ones, have
been extirpated by land use changes is an open question. Our
knowledge even of Maine’s current biota is far from complete,
especially for the small, the inconspicuous, the economically
unimportant, and those with too many legs.
Our research shows that the relative abundance of tree species
in Maine has also changed since presettlement times. The largest
declines have been for beech, yellow birch, hemlock, oaks, and
spruces; the largest increases have been for red maple, poplars,
balsam fir, and white pine. These transformations were caused,

albeit through complex and often indirect means, by the people
who settled and have lived in Maine for these last few centuries.
Increased fire incidence during settlement favored birches and
white pine and acted against fire-sensitive species such as red
spruce, hemlock, and beech. Accidentally introduced beech bark
disease has decimated beech. Frequent harvesting has favored
species that respond well to disturbance, such as poplars (aspens),
paper and gray birch, black and pin cherries, and red maple. In the
north, 150 years of spruce harvesting has benefitted balsam fir.
The physical structure of Maine’s forests has changed, too.
Maine never did support giant trees, with the exception of some
white pines, which were not as abundant as one might think
(Table 1). But because of high harvest levels, trees in Maine today
are much smaller and younger than in presettlement times. The
Maine Forest Service’s most recent statewide inventory found
that of trees over 5 inches in diameter, only 7.2 percent are in the
13- to 21-inch diameter range, and only 0.5 percent are larger
than 21 inches. For comparison, of trees in the old growth at Big
Reed Forest Reserve larger than 4 inches in diameter, 20 percent
are greater than 14 inches and 5 percent are greater than 20
inches. Land survey records suggest that about 60 percent of the
presettlement forest of Maine was older than 150 years, a value
that had declined to about 1 percent by 1995. Of the original old-
growth forests, only about 0.05 percent remain today.
After examining the old growth at Big Reed Forest Reserve,
we also suspect that the larger, older trees of the presettlement

forest gave these woods a different texture beyond just diameter
and height, for large specimens of some species simply look
different from the smaller versions we’re used to. The typical
shiny yellow, somewhat stringy bark of yellow birch trees, for
example, is replaced by large, grayish, platy blocks on large
trunks of this species.
The Maine Woods remain a vast territory that supports a wide
range of species. The last four centuries of land use, however, have
altered the original forest, favoring generalist and disturbance-
associated species, reducing tree size and age, and decreasing
structural complexity. The southern Maine forest has changed
from an old-growth mixed-hardwood forest to a network of
suburban and rural forests, much established on formerly cleared
land. The northern forest has changed from a structurally het-
erogeneous spruce-hardwood forest to a more homogeneous,
younger fir-spruce forest. Although vast and complex, the modern
Maine forest is very much a product of human culture.
What might this mean for the future of Maine forests?
Returning to the presettlement forest is not possible, given the
scale of forest and environmental change. On the other hand, we
can support elements of that landscape – mature forest, coarse
organic matter, structural complexity – that are essential for the
maintenance of biological diversity. Past land use matters, as it
clearly constrains what is possible for future forests. But Maine’s
forest history tells us that there are many potential paths within
those ecological boundaries.

Lessons in Planting Tree
f you’ve ever tried to grow a tree from a single seed, and failed, you’ll probably
want to know how the New Hampshire State Forest Nursery manages to grow
about a quarter of a million trees this way each year. The nursery, part of the New
Hampshire Division of Forests and Lands, has been growing seedlings in Boscawen,
just north of Concord, for over 100 years. It is a point of pride that their seedlings are
grown from locally collected seeds in order to be well adapted to New Hampshire’s
climate and soils. All 50 varieties of shrubs and trees leave the nursery when they are
between one and four years old and less than one foot tall.
On the day of my visit, highbush cranberry berries are spinning in a washing-
machine-like drum. As the pulp collects on the edges of the drum, the pink lentil-shaped seeds
are funneled down a chute to a waiting bucket. Scotch pine cones are tumbling and shaking in
antique machines designed to shred the cones and clean the seeds. Bagged conifer seeds wait in
the freezer. I follow Howard (Howie) Lewis, nursery forester at the New Hampshire State Forest
Nursery, past trays of acorns, cones, and hazelnuts to his office, where I begin my education on
growing trees from seed.

Seeds LESSON1You need lots of seeds.
“We don’t collect handfuls, we collect pailfuls,” explained Lewis. “If we can fill
a pickup truck, we do.” Red and silver maple seeds mature in June, and crews
have to be there the day they come down. “If they’re ripening and we know a big
storm is coming, we’ve got to jump in the truck with our tubs and our rakes,” said
Lewis. Some of the best collection locations for maples turn out to be cemeteries.
“They’re clean – and trees growing in the open tend to produce more seed.”
In a good seed year, nursery workers gather three or more bushels of maple
seeds, called samaras. “We try to collect one or two years ahead,” explained seed
specialist Nancy Connors. She is still planting balsam fir seeds collected in 1988,
but some seeds have to be collected every year. (The shelf life of bayberry, for
example, is only six to eight months.) Germination rates vary widely from species
to species and year to year; Nancy Connors’ germination tests on each seed
batch determine the numbers planted and their spacing in the nursery fields.

LESSON 3Good acorns and bad acorns look just the same.
In a good year, you’ll find piles of acorns on the ground by early fall. They all look
perfectly sound, and quite a few people gather acorns beneath their favorite trees
and bring them to the nursery. Lewis is happy to receive these gifts, but he always
tests the acorns for viability. Without fail, the donated acorns float in water, mean-
ing they are no good. Turns out that squirrels, who are such helpful gatherers of
conifer seeds, are no help for oak. Instead of collecting ripe acorns and placing
them in convenient caches, squirrels spirit good acorns away immediately, leav-
ing the bad ones behind.
High winds, heavy rain, or an early hard frost bring the acorns down. “That’s one
you have to watch by the day,” Lewis said. “You keep an eye on the roadsides on
your way to work.” At the first cue, the seed collectors go out and quickly shovel
up newly fallen acorns before the squirrels get them. The nursery might plant
20,000 acorns in a year, but only one out of three acorns will make it.
LESSON 2You can’t grow a pine tree from a pine cone.
“Conifers are a unique thing,” said Lewis, tapping a Scotch pine cone and hand-
ing me a seed. It’s just a wisp in my palm, a weightless black speck attached to
a translucent wing. “Most conifers have a seed that looks like this,” he explained.
“They use the wing to fly away from the mother tree.”
The seeds of most native conifers are released while the cones are still hanging in
the tree. By the time the cones fall, they are fully open and empty of seeds – unless
they’ve been cut and dropped by squirrels. Squirrel stacks are highly convenient
for nursery staff when they go out collecting. Lewis pulls up a few photos on his
computer showing Norway spruce cones in piles in the woods. “That’s a five-
bushel cache. We like those,” he said, explaining that the squirrels collect more
than they need and that generations of squirrels use the same caching locations.
The cones of white pines ripen in August when the weather is still warm and the
sap is sticky. Nursery staff will take a welcome break from weeding fifteen miles
worth of seedling beds to go collecting. Old clothes are a must for this job. After a
few days of collecting white pine cones, your pants stand up by themselves. After
a week, you have to throw them away.
In late October, the crew heads to the top of Mount Kearsarge to harvest red
spruce cones. “They’re all squirrel cuts,” Lewis said. But squirrels won’t cache
red spruce. “They put two or three cones here and two or three cones there. You
can’t tell the difference between this year’s cones and last year’s because both
are brown, but this year’s have pitch on them. We crawl around on our hands and
knees all day and end up with a bushel or two.” At 5,000 cones a bushel, 50 good
seeds per cone, it’s still a good haul.
If timber is being harvested on state lands when the cones are ready for harvest,
Lewis is right there with his crew as soon as the trees come down. “We are
opportunists,” he said, “And we can always use more seeds.” After the cones are
collected, they are air dried for a few weeks until they open. Then the seeds are
extracted using antique machines with names like the squirrel cage (a tumbler),
clipper cleaner, de-winger, and shaker. The resulting handful of clean seed is quite
valuable. “Pure gold,” said Lewis, holding up a one-pound bag of eastern larch
seeds worth close to $400.

LESSON 5Improvise.
Each time the nursery adds a new tree or shrub to the catalog, Nancy Connors
researches methods of seed extraction and germination. At first, winterberry holly
did not germinate well. The seeds foamed like soap lather when she rinsed them
and, through trial and error, she discovered that they had to be rinsed until all the
lather subsides. In other words, “When you are sick of rinsing it, rinse it again.”
This is part of nature’s plan. As Lewis explained, “A lot of fleshy seeds have to
run through a bird’s stomach and have to be super-clean. If they germinate easily,
they would compete with the parent plant.”
When Connors arrived, a slim book from the US Forest Service held all the
instructions she could find. The current edition of The Woody Plant Seed Manual,
weighing nine pounds and covering 1,300 taxa, still does not contain the detail
she needs. This book recommends floating wild rose seeds in water and keeping
those that sink. After none of her wetland rose and Rosa rugosa seeds germi-
nated, she took a look at the floaters and the sinkers under the microscope. “I
was throwing the good ones away,” she confessed with a laugh, noting the logic
that when roses grow near water, their seeds will need to float away to come in
contact with soil.
Lewis compares notes with people at the New York State Nursery, only to find
regional differences. In New York, they have to do root cuttings of red osier dog-
wood; they can’t get it to germinate. In New Hampshire, they just plant the seed.
“The books don’t talk about that,” he said
When the nursery opened in 1910, they sold white pine, red pine, and white
ash, primarily for reforestation. Now seedlings are purchased for songbird and
other wildlife habitat, wetland restoration, stream bank control, and Christmas
tree farms.
“Native shrubs have been a major part of what we’ve added in the past 15
years,” Lewis said. “We are always on the lookout for new species we can add
– for example, wetland shrubs that can fill a niche for songbirds.” Maple-leaf
viburnum will soon be added to the catalog, and they’re working on obtaining
seed for spicebush and summersweet.
By the end of my day at the nursery I’ve heard about ridge tops, treetops, and
squirrel caches that provide bushels and truckloads of cones and seeds. I’ve
seen drying trays of scrub oak, hazelnut, red osier, wild raisin – entire habitats
distilled into their concentrated parts. But one image sticks in my mind – a freezer
packed with half a ton of conifer seeds. With a thousand pine seeds, or a million
white spruce seeds, in each four-pound bag, this translates to thousands and
thousands of acres of forest.
“What we do is unique,” said Lewis. “Here we have what you find in the wild
– New Hampshire grown.”

LESSON 4Guard your seeds.
Lewis is standing by a newly planted stretch of eight thousand hazelnuts.
Stamped neatly across the 300-foot length of black protective fabric are the
muddy tracks of wild turkeys that came running to investigate. “If we didn’t cover
them, they would be gone in one night,” Lewis said. “The next morning, it would
look like a rototiller had gone through here.” As quickly as a walnut is planted, a
squirrel will take it away – unless it’s securely covered.
The nursery grows about 5,000 walnut seedlings each year, planted in the middle
of the field to keep them as far as possible from the mice and squirrels. “They have
a pretty good nose and can sniff them out,” Lewis said. “Someone planting them in
their backyard would have to cover them with a screen because nine times out of
10 the squirrels will find them. Acorns, you have a chance. Walnuts, you don’t.”
As more customers seek plantings that will serve as food for wildlife, the nursery
is growing more varieties of shrubs with persistent fruits. Wildlife are drawn to
the planted seeds, young seedlings, and ripening fruits on hedgerows, and this
becomes a double-edged sword. On the bright side, the nursery and the adjoining
trails of the state forest are a great place for bird watching; on the down side,
seed harvests are diminished and sometimes eaten entirely. Occasional moose
tracks cross the seed beds, and nursery staff go to great lengths to protect young
fir seedlings from becoming the winter browse of deer.

Black Locust Robinia pseudoacacia
You’ll not often find me singing the praises of a nonnative
tree, but there are just too many good things about black
locust for me to want to cut them down and throw
them on the buckthorn pile. It would be like get-
ting rid of apples or honeybees – and they’re both
imported from much farther away, from a different
continent.
Still, some people hate black locust and, indeed,
it is only in the Northeast now because, starting in
early colonial times, farmers carted it in from its
native range in the southern Appalachians and on
the Ozark Plateau. In its defense, however, the species
was found in our area before the last glacier chased it
south. It just failed to find its way back home when the
glacier retreated.
During the winter, full-sized locusts have a wild,
disheveled look: twisted, stark, with deeply ridged black
bark, but still, in my opinion, strikingly beautiful. But
when the blue-green leaves unfurl from their buds the
skeletal structure is hidden and the trees undergo a complete transformation. The large
compound leaves are made up of 7 to 19 little egg-shaped leaflets, and somehow the
crown looks both dense and delicate. When the showy, fragrant, milk-white flowers come
out, locust-lined roadsides are temporarily gorgeous.
And temporary it is; the show lasts only about 10 days. The intense orange-blossom
scent of the flowers brings in droves of insects: a mix of honeybees, wild bees, wasps, flies,
and who-knows-what other insect orders, all fighting to get into the pea-shaped flowers.
Locust honey is famous, both for its flavor and color – well, really, its lack of color, for
pure locust honey is as clear as water and so high in fructose that it can be stored for a
long time without crystallizing. We never get honey like that in the Northeast because
locusts bloom in the second half of May, at the same time that many other species are
also producing nectar.
Farmers brought black locust to the Northeast because the wood makes superb, rot-
resistant fence posts, a product so essential in the pre-pentachlorophenol days that, as
word spread, most every farmyard soon had a grove of locusts used for that purpose.
Flavonoids in the heartwood allow the wood to last over 100 years in soil. Admittedly,
black locust does have some dislike of being fenced in itself and it sends up root sprouts
in every direction; the clonal clumps can walk, step by step, across the land.
This can be a desirable trait in some situations, such as when it is used to reclaim
mining sites or other treeless wastes. Like many other legumes, black locust fixes nitrogen,
an ability that is rare among trees of temperate regions. It tolerates severe frosts, drought,
air pollution, and high light intensities, and grows rapidly under the most adverse
circumstances. On the flip side, it is disliked because of these very same traits: this sun-
lover is capable of spreading into any and all openings and one tree planted in the yard
can quickly send up enough root sprouts to create an impenetrable thicket. Also, the twigs
and bark are poisonous to livestock.
In addition to its decay resistance, the wood neither shrinks nor swells very much.

These traits made it the wood of choice for treenails, known as “trunnels,” the pegs that
were used to attach a ship’s planks to her ribs. This might seem like a trivial application,
but for the wooden boat builders of yore these little things made all the difference.
Metal fasteners corrode, and oak – used before locust was discovered in the New World
– shrinks more and is more susceptible to decay.
Abraham Lincoln is said to have split rails and fence posts from black locust logs in his
early years. When telephone and power lines were stretched across the country a century
later, the species found another niche: it was used to make the wooden pins that held the
insulators to the cross arms.
Black locust is still appreciated in much of the world. First imported to France in
about 1636, it has since been planted widely in many European countries and in China.
Eighteen percent of the forest trees in Hungary are black locusts, mostly in plantations
where they are cultivars, selected for straight (instead of the usual wobbly) stems.
One of these selections, called shipmast locust, was first noticed in Virginia. It
was propagated on Long Island in the 1700s, using sections of the roots that are even
more intent on sprouting than those of normal black locust. Interestingly, this selection
– apparently it’s not different enough to be called a variety – is also more rot resistant
than a normal locust and is less susceptible to the tree’s greatest foe: the locust borer
(Megacyllene robiniae). This borer can wreck the timber potential of black locust,
especially when the trees are grown on substandard sites. Good growing conditions, as
well as good genes, help reduce borer damage.
A much more obvious and widespread pest is the locust leaf miner; these insects
turn lovely locust leaflets to a dingy gray-brown over the course of the summer.
The pretty adult beetles emerge from the leaf litter just as locust leaves begin
to unfurl in the spring, and the female beetles do a little chewing as they lay
eggs in groups of three to five on the undersides of new leaves. It’s the tiny
larvae, imprisoned between the upper and lower layers of a leaf, that do
the real damage. Relentlessly, they chew their way around and around in
a leaf ’s interior until there’s no more green to be found. It’s a tribute to
the locust that it can survive total defoliation, year after year. Most trees
can survive this for only a couple of years.
Here and in several European countries, locally grown black locust
is promoted as a sustainable substitute for decay-resistant tropical
hardwoods and pressure-treated lumber. After the EPA restricted use
of the highly toxic pentachlorophenol to prevent wood decay in the
early 1980s, chromated copper arsenate (CCA) was used in just about
every outdoor application, before people realized that arsenic was
leaching from the wood wherever it was used – especially worrying
in playgrounds. The EPA gave that one a thumbs down in 2003 and
now ACQ, a less toxic (and less effective) mix of copper oxide and a
quaternary ammonia is used just as widely. However, it, too, is corrosive
as well as toxic.
Nowadays, the need for telephone insulator pins, treenails, and fence
posts isn’t what it used to be and black locust has continued to flourish, making
it widely available. Consequently, the timber value is low. Not only is it well
suited for outdoor applications, at present it’s also inexpensive – assuming there’s a local
source or that you can find someone to mill it out for you. The wood, which is stronger
and harder than white cedar, provides a local, safe alternative to the southern yellow pine,
pressure treated with toxic chemicals, that is now so common. If black locust can make
lawn furniture and playground equipment safer, this may diminish its bad reputation.

Butterflies Take Note Before Taking FlightClimate change is affecting a wide range of wildlife, from plants and bees to birds and
trees. A new study led by biologists at
Boston University adds butterflies to the
list, finding that butterflies emerge earlier
in warmer years.
The researchers focused on the flight
periods of 10 species of butterflies in
the elfin and hairstreak families, using
museum records and 23 years of data col-
lected by members of the Massachusetts
Butterfly Club. “We picked those species
because they’re common and relatively
easy to identify by local experts,” said
Caroline Polgar, a postdoctoral research-
er at BU. “They’re also short-lived species
who only fly for two or three weeks. We
felt we would be better able to detect a
shift in emergence times with species that
have a short flight window.”
They found that when average tem-
peratures were higher than normal, the
butterflies came out earlier. Elfins, which
fly in late spring, emerged 4.8 days earlier
for each degree Celsius, while the summer-
flying hairstreaks emerged 2.6 days earlier.
Polgar explained the difference
between the spring and summer species.
“Spring temperature changes are usually
more dramatic, sometimes going from
very cold to warm, whereas in summer
it’s already warm so the temperature dif-
ferences aren’t so dramatic. We see the
same thing with plants. Spring flower-
ing species respond more to temperature
changes than summer flowering species.”
The temperature period the research-
ers examined was the two months before
the butterflies were due to emerge. If it
was warmer than average in March and
April, for instance, the elfins were likely to
emerge early. Polgar said that the change
over time was significant for some species
and less so for others, “but should temper-
atures continue to warm, it is extremely
likely there will be a significant change in
emergence times for all species.”
The good news, she added, is that but-
terflies appear to be responding to tem-
perature at a rate similar to that of plants.
Because of the close relationship between
them, if one responded differently there
could be “a catastrophic timing differ-
ence,” meaning that the leaves or flowers
may not be available when the butterflies
or their larvae need them.
That is a concern the researchers raise
with birds. Studies have shown that bird
arrival times in spring are much less
responsive to local temperatures than
plant and insect populations. Some bird
species, especially those that migrate rela-
tively short distances, have been arriving
earlier in the spring, but others have not
– perhaps because they take cues for their
longer migration routes from photoperiod
(the number of hours of light in a 24-hour
period) as well as temperature. That could
raise the specter of ecological mismatches
as migratory birds arrive after the peak
abundance of their insect food.
A Rugged Pair of Genes
A project to map the genes of spruce and
pine trees has revealed that the genome
of conifers has remained pretty much the
same for more than 100 million years.
This stability explains why today’s coni-
fers look like fossil conifers dating to
before the age of the dinosaurs.
According to Jean Bousquet, a profes-
sor of forestry at the University of Laval
in Quebec, conifers were the first plants
to evolve after ferns, and fossil records
of conifer needles date back 300 mil-
lion years. That’s about when flowering
plants diverged from the conifers. Since
then, the flowering plants have under-
gone major changes, evolving into about
400,000 species, while today there are
just 600 species of conifers. The stability
of the conifer genome goes hand in hand
with its low speciation rate.
“Flowering plants have totally changed
their morphology through the years – they
include the grasses, shrubs, hardwood
trees, vegetables, all kinds of flowers,”
Bousquet said. “It’s evolution at a large
scale, and we see that in their genome.
They have had a lot of reshuffling in
their genome, but the conifer genome has
remained stable.”
Bousquet speculates that one reason
for this stability is that the conifer genome
is very large.

“The spruce genome is 20 times the
size of the human genome,” he said. “We
call it genome obesity. It has become
progressively larger over time, and at the
same time it has experienced genome
paralysis. It is so big that it can’t move
or change very quickly.” He considers
the large size and unchanging nature of
the conifer genome as a sign of genome
aging, just like when people age they slow
down and gain weight. He notes, how-
ever, that genome aging is not a sign that
the trees are likely to die out soon.
Details of the research by Bousquet
and colleagues at the University of Laval
and the Canadian Forest Service were
published in the journal BMC Biology.
The study was conducted by compar-
ing the genome macrostructure for 157
gene families present in both conifers
and flowering plants. While they did find
genetic mutations and other small-scale
modifications in the conifer genome, the
scientists said the macrostructure of the
genome has remained stable.
Bousquet thinks this stability occurred
in part because the conifers adapted to
their environment very early on and
haven’t needed to change much. “They
survived the glaciations, they survived the
dinosaurs, they appear to have achieved a
balance with their environment long ago,”
he said.
“These plants also have a lot of genet-
ic diversity – among the highest of all
plants – which has enabled them to adapt
to changing conditions. That’s why they
have survived for so long . . . In contrast,
flowering plants are under intense evolu-
tionary pressure as they battle for survival
and reproduction.”
Soil: Can It Take the Heat?
Soils throughout the world store more car-
bon, in the form of organic matter, than
all of the vegetation and atmosphere
combined. Microorganisms in the soil –
bacteria, fungi, protozoa, nematodes, and
other organisms – feed on that organic
matter and release large quantities of car-
bon dioxide. Historically, this release of
CO2 has been balanced by the photosyn-
thesis of plants, which absorb about the
same amount of CO2 as the soils release. UNH professor Serita Frey and graduate student George Hamaoui collect soil samples.
59Northern Woodlands / Summer 2013
But according to a study by University of
New Hampshire Professor Serita Frey, as
global temperatures rise, additional car-
bon is released from soils into the atmo-
sphere – at least in the short term.
“While they’re low on the charisma
scale, soil microorganisms are critically
important to the carbon balance of the
atmosphere,” said Frey. “If we warm the
soil due to climate warming, are we going
to fundamentally alter the flux of carbon
into the atmosphere in a way that is going
to feed back to enhance climate change?”
Frey and colleagues at the University
of California-Davis and the Marine
Biological Laboratory simulated the
effects of climate change on the soil by
placing heating cables 10 centimeters
beneath the soil surface at study plots
in the Harvard Forest in Petersham,
Massachusetts, to learn how a warming
world would influence what takes place
in the soil. The study plots, one heated for
two years to simulate short-term warm-
ing and another heated for 18 years, were
warmed to 5°C above ambient tempera-
ture. The project was designed to mea-
sure the efficiency of the soil organisms.
“If an organism takes one molecule
of glucose, for example, as a food source,
some fraction of that goes to cell mainte-
nance and growth, and some portion of
that gets lost to the atmosphere as carbon
dioxide,” she explained. “The more effi-
cient the organism is, the more of that food
source stays in the cell; the less efficient it
is, the more is lost to the atmosphere.”
What they found is that as tempera-
tures in the soil increase, the soil micro-
organisms become less efficient, releasing
more carbon dioxide into the atmosphere.
That effect diminishes over time, how-
ever. The organisms appeared to become
more efficient in the longer term, sug-
gesting that the microbial community
becomes acclimated to the warmer soils
or the community somehow changes.
“The positive feedback response may
not be as strong as we originally pre-
dicted,” Frey said. “It could be that differ-
ent species become more abundant and
others less abundant over time. Perhaps
there’s also a shift in physiology, an evo-
lutionary adaptation to those conditions.
We just don’t know yet.”
The next step will be to conduct a
DNA analysis of all the organisms found
in the soil to identify the species and
see if the community changes as the soil
warms. The researchers also plan to con-
duct laboratory tests of the physiology of
the organisms to learn if their metabo-
lism adapts to the warmer conditions.
“Ultimately, we’d like to know how
climate change is affecting all of these
organisms,” she said.

Building a Lumber Pile
By Carl Demrow
TRICKS of the trade
The demise of the local sawmill has been closely
followed by the rise of the sawyer with a portable
bandsaw mill. Usually the sawyer will come to your
house, set the mill up parallel to your log pile, and cut
custom boards for you, but it’s often up to the client
to furnish a tailer who will stack and sticker the sawn
lumber. If you lack teenaged children, this job may
well fall on you.
Much of your satisfaction – or dissatisfaction
– from a custom milling project will be the result of
how the lumber is treated after it is pulled off the
mill’s bedrails, so proper stacking is critical.
You’ll want to build your lumber pile perpendicular
to the prevailing wind. It’s not a good idea to stack
green lumber inside a closed building, as air movement is
important to wick moisture away. Use cinder blocks for a base, and
level them as best you can. The goal is to have the first boards a foot off the ground.
The stack should be 3 to 4 feet wide, and supported every 2 feet to minimize warping.
Span the cinderblocks with level, seasoned 4x4s (known as dunnage) and leave a gap between boards
to allow air penetration.
For the lumber to dry properly, you’ll need to sticker your pile. Stickering refers to the use of narrow
strips of wood – typically 1”x 1” – between the layers of lumber to allow adequate air flow. For best
results, the stickers should all be the same length (the same as the width of the pile) and rot- and stain-
free (to minimize staining your lumber). In a perfect world, the stickers would be dry, but billions of
feet of wood have been stacked using green stickers created in the board edging process with perfectly
adequate results.
Keep each layer of stickers directly over the dunnage and lined up with the stickers below and keep
the edges of the outside boards plumb. A sticker placed right at the end of a board tends to stop deep
end splits from developing. While 2-foot spacing is adequate for most species, you may want to con-
sider 18 inches or even 1-foot spacing for species that warp excessively, like sycamore or elm.
Build up to a height you are comfortable with, add 6 inches of dry dunnage on top, then cover the
pile with metal roofing, making sure that the roof has a 6-inch overhang and that nothing is sticking
out in the weather.
How long will it take for your lumber to season? Softwood generally seasons faster than hardwood,
but just how long it takes depends on how much moisture the log had in it when it was cut, the time
of year, the thickness of the lumber, how much it is exposed to wind and sun, and how good you are at
stickering your wood. The US Forest Service estimates that it takes between 60 and 200 days to air-dry
green, 1-inch-thick white pine lumber to 20 percent moisture content.
Blue stain is a common problem with sawn pine, though it usually occurs in the log, not in the
boards. To avoid blue stain, have your pine sawn during the winter, then sticker it and cover the top
so the wood seasons prior to warm weather. If you’re using your lumber outside, say for siding that
outbuilding, the blue stain will eventually weather away.
Sticker stain is another common problem in white wood. It’s caused by slow drying at warm tem-
peratures when the lumber is above 40 percent moisture content. The only sure way to avoid sticker
stain is to achieve fast drying, and to do this you might be wise to invest in kiln-dried stickers that have
a diagonal groove cut into the top and bottom flat faces, which allows for optimum air circulation.

None of this should come as a surprise. All of Maine is right
in the middle of the northern temperate zone, but our little
region is even more middling than the rest of the state. We’re
smack-dab on the 45th parallel, midway between the North Pole
and the equator. We’re 60 miles from the Canadian border and
60 miles from the Atlantic coast. We do get occasional inklings
of the Arctic in winter (-39°F) and of the tropics in summer
(101°F), but most of the time we’re a model of moderation, as
middle of the weather road as you can get.
Our location does not, of course, make us immune to weath-
er disasters – witness the hurricane of 1938, the April Fools’
Day flood of 1987 that swallowed houses and bridges in one
gulp, and the ice storm of 1998 that may well hold the record for
property damage statewide. Still, events that devastate coastal
New England with hurricane-force winds and storm surges
often just sideswipe us as they pass by. So it was with Nemo; so
it was with Irene in 2011 and Sandy in 2012.
But getting off light is no cause for full-scale rejoicing if the
homes of your friends only 20 or 50 or 200 miles down the road
are getting torn off their foundations. And when, in a span of
two years, we’ve had two hurricanes, a record-setting blizzard,
and a fluky warm winter visit our region, even the most san-
guine weather observer has to sit up and take notice.
Then, too, the animals have more and more to say about our
weather every year: the northward march of ticks, the squad-
rons of turkey vultures circling in our skies, the tufted titmice
and the red-bellied woodpeckers at our bird feeders, the New
Hampshire bears that have given up hibernating. As a Koyukon
elder once said to anthropologist Richard Nelson, “Every animal
knows way more than you do.”
Robert Kimber has written often for outdoor and environmental magazines. He lives
in Temple, Maine.
Talking about the weather is supposedly the height of dopiness, a
display of intellectual poverty so extreme that it evokes neither
pity nor contempt from those exposed to it, but only embarrass-
ment and a desire to escape. If you can’t think of anything better
to talk about than the weather, the conventional wisdom says,
then hold your peace. Just shut up.
I do not agree. I’ve always loved conversations about the
weather – weather present, weather past, weather future. I’m
particularly fond of our upcountry Maine weather, so I like to
brag about it any chance I get, even though I can’t take the least
bit of credit for it.
What spectacular weather we had, for instance, on February
7, 2013, a brilliant, bracingly cool (12°F) but not bitterly cold
winter day, with the sunlight booming down out of a sky as blue
as a sky can be and fading to a lighter, paler cornflower blue
around the horizon. A couple of fat gray squirrels reveled in the
warmth of the sun as they lunched on sunflower seeds the birds
had let fall from our feeder. In the Temple post office I found
general agreement that this was a nippy day, but one whose
nippiness in no way detracted from its beauty and the sense of
wellbeing it inspired in humans and gray squirrels alike.
But then, Nemo, the Blizzard of 2013, moved in for the next
two days, just as the meteorologists told us it would, giving us
about 72 hours of more blowing than snowing. The official
snowfall, measured right next door to us in Farmington, was
a mere 9.2 inches. Given the wind, however, those 9.2 inches
translated into only 4 in our driveway but 32 right outside our
kitchen door. On Sunday, February 10, we went right back
into another halcyon day as sunny, windstill, and sweet as the
Thursday before.
Now I know that halcyon days – if you chase “halcyon”
back to its origin in Greek mythology – can apply only to
those days in mid-winter when Aeolus, the god in charge of
the winds, reins them in and calms the waves so that his
daughter, Alcyone, whom the gods transformed into a
kingfisher, can safely build her nest and lay her eggs
on the shore. But what I find so remarkable about
our local weather is its ability to produce halcyon
days year round: sunny Indian summer days
when the air is crisp and clean, spring days when
the hills first start greening up, even midsummer
days when the humidity lifts and you think you
could reach up and touch the top of the sky.
Halcyon days – whether they come winter or
summer, spring or fall – are days of calm; days
when we may be busy but are unhurried, content
and carefree; days when all feels right with the
world.

With the Grain: A Craftsman’s Guide to Understanding WoodBy Christian Becksvoort
Lost Art Press, 2013
For cabinetmakers, both professional and ama-
teur, the name Christian Becksvoort will have the
same kind of resonance that Babe Ruth or Mickey
Mantle will have for a baseball fan. Becksvoort
has been building elegant, superbly crafted fur-
niture inspired by Shaker designs for over 40
years, and his list of articles in Fine Woodworkingmagazine, where he is a contributing editor,
is longer than both my arms put together. An
Amazon customer who must have read a library
copy of Becksvoort’s 1983 book In Harmony with Wood and subsequently tried in 2003 to buy a
copy on Amazon, mourned that the book was no
longer in print. He need mourn no longer because
Becksvoort has thoroughly revised In Harmony with Wood and republished it with a new title,
Working with the Grain.
Both those titles and the book’s subtitle, ACraftsman’s Guide to Understanding Wood, accu-
rately reflect Becksvoort’s focus. Understanding
wood and working in harmony with it in every
stage from tree to tabletop is what this book is
all about: how wood grows, how it is sawn and
dried, how it responds to variations in humidity
and temperature, how the orientation of grain, as
well as methods of joinery, combine to produce a
finished piece that will be stable under changing
conditions, as well as pleasing to the eye.
A graduate of the University of Maine’s School of
Forest Resources, Becksvoort draws on his exten-
sive background in forestry and wood technology to
provide in concise, readable form what every furni-
ture builder ought to know about wood. His book’s
five chapters are organized in a progression that
begins with the tree and ends in the woodworking
shop. Chapter One is about the structure of wood
and the properties that determine the workability of
different tree species and the appearance finished
pieces will have. The second chapter, “Wood and
Tree Identification and Characteristics,” delivers
on its title, describing not only the features needed
to identify 30 North American trees, but also the
properties – such as color and luster, density and
specific gravity, grain and figure – that make each
one suitable for particular woodworking purposes.
This chapter is illustrated with clear drawings of
tree profiles, twigs, leaves, nuts, and fruits, as well
as with photographs of bark, grain, and end grain,
the latter enlarged 25 times to show the porosity of
different woods.
Chapter Three, a concise yet comprehensive
account of woodlot management and tree har-
vesting, lays out the elements of a multiple-use
strategy that will protect the wildlife habitat and
recreational potential of the forest while encour-
aging the growth of furniture-grade trees with
thinning and pruning. Chapter Four, on sawing
and drying wood to make it ready for the shop,
is the logical penultimate step in Beckvoort’s
progression toward his final chapter, “Working
with Solid Wood,” which describes in detail strate-
gies he has either learned from past masters or
developed himself to compensate for the shrink-
age and expansion that even optimally dried wood
undergoes in response to the changing seasons.
This whole book is a feast of knowledge, and
its final chapter tops it off with a chance to see a
master craftsman putting his knowledge to work.
I won’t attempt to summarize. Suffice it to say
that for me, whose furniture building has never
advanced much beyond the plant stand I made in
my seventh-grade industrial arts class, Working with the Grain – meticulously researched and
written and generously illustrated with drawings,
photographs, and charts throughout – has been
an eye opener on the kind of craftsmanship that
aspires to, and achieves, the level of art.

Sudden Eden By Verandah Porche
Verdant Books, 2012
Intensely personal poetry only works if readers
can recognize something of themselves, or some
universal truth, or something fun or beautiful in
the prose. If it’s there, the poet and reader achieve
some sort of mental synthesis – sort of like a
grafted white pine.
If you lived through the 1960s and ’70s in the
rural Northeast, you’ll see yourself in Verandah
Porche’s new collection of poetry, Sudden Eden,
at which point my guess is that the graft will
take. Porche, a city girl from Teaneck, New Jersey,
moved to a ramshackle Vermont farm in 1968 and
went on to become a minorly famous figurehead of
the back-to-the-land movement. You’ll recognize
the tension between the play-farmer artists and the
granite locals in these poems. Not surprisingly, the
book’s release has garnered a lot of nostalgic press
in Vermont about that tumultuous time.
But if you didn’t live through that era, there’s
still plenty that’s universal and beautiful in these
poems. I was born seven years after her commune,
which is to say I never knew rural Vermont (I could
be speaking for any rural state here) without a
countercultural influence. Our role models growing
up were sixth-generation dairy farmers who listened
to Paul Harvey and organic hippie farmers who
liked the Grateful Dead – they were all part of the
same place.
For me, and I suspect for many of you, you’ll
find that the poems in Sudden Eden work just fine
as homages to rural life – and Porche is as good
a chronicler of this as anyone I know. We collect
chanterelles with her (“a trill of thrush made
edible”); split and haul bucks, and forests, with
local boys; marvel at the overlapping home ranges
of Arctic Cats and Firebirds. That she can write
poems about the sticks with such authenticity is
not surprising, considering that when other back-
wood LIT

to-the-landers moved back to the city, Verandah
stayed. Forty-four years later she still lives there.
Her life’s work has been to help kids in schools
and factory workers and seniors and people in
crisis centers tell their stories; to help them fall in
love with language. If there’s a touch of affection in
that last line it’s because I was one of those people
– a fourth grader in Shaftsbury Elementary School
enthralled with this strangely named lady and the
wild words that fell off her tongue.
Verandah the writer can be a mad hatter, for
sure, in that distinctly late 1960s Trout Fishing in
America way. In one poem she uses the sound of
every letter in the alphabet to make words (CroK
balls); in another she instructs a reader to fill a black
sky-speckled kettle with a rolling boil. Steam quart
jars. Can light. Seal and cool. But she can also be
simple and spare. “100 Years of Squares and Reels”
evokes a wintertime dance in a hill-town grange
hall, a milk maid in a pretty red dress. The lines in
the poem are as sparkling clean as fresh snow.
In “Blue Seal” she opens with the phrase:
Did you ever fall open
Like a hundred-weight
Of Blue Seal Dairy Ration?
And could have ended the poem right there.
The very best poems in Sudden Eden are
playful, challenging, odd, and disciplined, which I
guess is another way of saying a mixture of the
33-year-old woman pictured on the front cover and
the 68-year-old woman on the back. “Stovepipe,”
which ran in the Autumn 2010 issue of Northern
Woodlands, paints a spare, gothic image of a fire
being laid in an old farmhouse. Dusk (“the light
bent down as if to milk”); young tough country kids
juxtaposed with an ominous image of a stovepipe
thinned to lace. In nine lines she paints an image
full of mystery and magic and foreboding. And
then on the third, or fourth, reading, you notice that
it’s an acrostic – the first letter of each line spells
STOVEPIPE. The mad hatter at work.
In “Trouble Time” we’re shown a woman in bed
lying next to an unfaithful spouse. It’s winter and it’s
late and he’s sleeping. She’s awake and thinking,
heartbreakingly, Let I be she. The poem’s last line:
O soothe, sooth, soot.
Subtract me.
Is soo Verandah. So playful and poignant at the
same time.

Peak Experiences: Danger, Death, and Daring in the Mountains of the Northeast Edited by Carol Stone White
University Press of New England, 2012
There’s something about wilderness rescues and mishaps that seems to bring out the voyeur in
many of us. Are we drawn to the cautionary tale,
fascinated by the raw power of nature and the
arrogance of some people in the face of it? Maybe
we just want to think to ourselves, “I can’t believe
they did that! I would never do something that
stupid!” Or maybe it’s a bit like a train wreck – we
just can’t help but look. Whatever it is, tales of mis-
fortunes in the wilderness have long been popular
in fiction and nonfiction, and those who spend time
in the mountains love to trade in such tales.
So what goes wrong? People go into the
woods, they make decisions (often influenced
by dehydration, hypothermia, bad map reading,
lousy communications, underestimating weather
conditions, overestimating fitness, and fear) and
Mother Nature just does what she always does.
In Peak Experiences, a few of the 54 stories are
recounted in standard accident-report form, but
most are told by the rescued and the folks who
had a close call. Many, like a good fishing tale, are
Yellow

entertaining, funny, and have a message to pass
on to the reader (assuming the reader is a soon-to
-be hapless fellow adventurer).
Peak Experiences is organized around such
topics as weather, rescues, treacherous places,
the dangers of water, and animal and avian
behavior. Each section includes a somewhat
oddball assortment of entertaining tales. Doug
Mayer’s story of getting himself out of the woods
with a broken leg, and Laura Waterman’s tale
of nearly drowning in her sleep in the middle
of winter both stand out, but my favorite was
Donna Brigley’s “Never Underestimate the Power
of Pudding.” Brigley’s story is of a much longer
journey, framed by her time in the mountains
and filled with uncertainty, loss, and searching.
She manages to convey how necessary spending
time in the mountains is to the health of her soul
while contemplating the inherent risks. She writes
about why she needs the woods. She ties it up in
a bow. And I’m a sucker for pudding.
The stories are great, but Peak Experiences is
also a helpful book. Advice and “Cliff Notes” of
backcountry travel wisdom are sprinkled through-
out each chapter. And the appendices include a
list of clubs and organizations that can get you
started in adventures in the outdoors, safety
guidelines, and suggestions for further reading.
All of the stories show the rewards of back-
country travel and the risks involved – risks that
apply to all, no matter how well prepared you are
or how impeccable your decision-making is. Those
who venture into the woods need to be skilled,
prepared, and fit, have good information and
dependable partners, and make sound decisions.
But they also need a bit of luck – for in the end,
it may just be that tiny bit of luck that makes the
difference between a close call and a tragedy.

These prices are for #1 hardwood logs, at least 8 feet long, with
three clear faces and a minimum 12-inch top diameter. In the
timber world, this is a log of average quality, not a prime sawlog
and not a poor one.
Landowners should remember that the dollar amount here
indicates what is being paid for logs that have been felled, limbed,
skidded, bucked, and delivered to a mill or buyer. The costs of log-
ging and trucking need to be subtracted from these figures to arrive
at the price paid to the landowner. Because every job is different,
these costs vary widely.
These data are compiled from interviews with suppliers and buyers
and from the most recent print and online versions of the Sawlog Bulletin, and are used by permission. For more information on the

note that many of these prices were reported three months prior to our
publication date, and current prices could be higher or lower.

Talking Timber
When Northern Woodlands first started reporting sawmill prices in the
summer of 2001, right about the time the .com bubble was bursting in
Silicon Valley, one could be forgiven for feeling a bit smug about the value
of their standing timber. Let the silly urban people invest in pets.com; we’ll
keep our money in tangible, traditional trees. Little did we know that the
1995-2005 peaks in securities markets, housing construction, and wood
products were not normal. In fact, this was its own bubble waiting to burst.
And burst it did for the big three hardwoods – sugar maple, black cherry,
and red oak. This graph shows the cliff face. If you were a forestland owner
But for now we’re left with this snapshot of 12 years, and the lessons we
might tease out of it. It’s interesting how the lower-grade trees held their
value through the fall, how yellow birch has begun to outcompete oak and
even cherry in some areas. Probably an economist would tell you that the
moral is to stay diversified, think total return, don’t try to time the market,
cut lightly and frequently. Probably the more philosophical lesson is that a
timberland investor should take her lessons from the trees. Grow slowly. Be
patient. Weather the drought years and the insects and the Wall Street col-
lapses and the fickle human fashions. People will always need hardwood
and, in the grand scheme of things, 12 years is no big chunk of time.

counting on your maple sawlogs to fund your retirement,
you’re probably still working. And, as one might
imagine, the collapse, coupled with competition from
imports and non wood substitutes, helped drive out the
mills that couldn’t adapt. This industry consolidation
has made collecting reliable data for this page difficult –
to the point where we’re going to discontinue reporting
mill prices in each issue.
It’s not all doom and gloom. Housing markets have
begun to recover and the hardwood markets should,
too. In our fall issue, we’ll be starting a regular profile
series on wood products companies that have perse-
vered and positioned themselves for success in this
new marketplace.

Craig Mooney, Valley Sunset, 48” x 48”, oil on canvas, 2008.
the outdoor PALETTE
Craig Mooney is a master of atmospheric perspective. He manipulates his oil paints to reflect the effect that
weather, atmosphere, and shifting light have on the appearance of a place. Mooney paints with a facility that
is fresh and exciting. Through his deft use of value, hue, and saturation, he is able to convince us of receding
distance and to play with what Leonardo da Vinci called “the perspective of disappearance.”
There is very little site-specific detail in Valley Sunset, and as Mooney explains, this is not a specific
locale; it is more an expression of how a dramatic sky interplays with the landscape in our region. This is a
place born of memory, experience, and a love of the Northeast. Though his landscapes may not be found
on a map, they are familiar and tenaciously rooted in the New England experience. We look at Valley Sunset and are reminded of Lake Champlain pushing north, of the Kennebec River snaking through farmland, or
of the Connecticut River Valley flanked by fertile croplands.
It is important to Mooney that when people look at his work, they are able to find their own experience
of place. Valley Sunset is one moment as the sun breaks through the clouds and lights up a valley. We all
know this moment to be beautiful and fleeting.
Craig Mooney is represented by galleries nationwide. Regionally his work can be seen at West Branch Gallery
in Stowe, Vermont, Jules Place in Boston, Massachusetts, and Gallery North Star in Grafton, Massachusetts.
He will have shows this summer at the Field Gallery in West Tisbury, Massachusetts and Maine Art in
Kennebunkport, Maine. Craig can be reached through his website, craigmooneystudio.com — Adelaide Tyrol

72 Northern Woodlands / Summer 2013
It was called a camp. A summer camp with a woods path leading
up from a sparsely traveled dirt road. We’d arrived by train, an
overnight trip, and we were met at the Brattleboro station by a
family friend, my father’s colleague. They were working on a
book together – the reason we had come to spend the summer
in Vermont. We had no car. It was 1945, the last year of the war.
I was five, my brother two.
As we wound up from the Connecticut River into the forests
near Wilmington, my father exclaimed, “Smell the air!” We
all breathed in air that was so cool and sweet. My father knew
Vermont air. He was born in Vermont. That was the other
reason we were here. My father wanted his children to know
Vermont, too.
The camp was on the lake. There was no telephone. “Your
ice will be brought weekly,” Mr. Barber, the real estate man who
opened the camp said to my mother. “There’s your icebox.” We
saw a shed through the window. A woodstove took up half the
kitchen floor. “Could roast a moose,” Mr. Barber said, patting
the stove’s cast iron flank. My mother blanched. “But you’ll cook
on this.” He gestured to a two-burner oil stove sitting on spidery
legs. “Here’s your oven.” He picked up what looked like a bread
box. “You set it on top.” He demonstrated to show my mother
how easy it would be to prepare meals for her family of four. He
turned a knob at the sink. Water gushed out in a silvery stream.
“It comes from the lake,” he said. “You’ll heat your hot water
on the stove.” “Don’t drink it,” he said, turning the water off.
“The well’s out back. Send the kids for the drinking water.” He
grinned at us. “Make sure you prime the pump, otherwise you’ll
wreck it.” My mother walked into the living area and sat on the
couch in front of the fieldstone fireplace. The couch swung back
and forth. It squeaked. It was a swinging couch on springs. My
mother burst into tears. Our father saw Mr. Barber out.
We spent the next eight summers there.
The camp was in the woods. The air around it smelled of
balsam, fresh and tangy. There were other camps on the road
but we couldn’t see them. The woods across the lake were
undisturbed by man. The camp had a porch across the front,
from which we could look deeply into the surrounding trees
– thick, dark, and green. My brother and I scanned the woods
for movement.
We became fascinated by chipmunks. When our parents
had drinks on the porch with guests, who came because of my
father’s work, my brother and I would strew cocktail peanuts up
the porch steps to entice chipmunks. Chipmunks, shy of adult

talk, remained aloof. But when we came out after dinner to
inspect, the peanuts were gone.
When it was just us kids, a chipmunk would hop up the first
step, grab a nut, and retreat to a nearby rock. We’d be extra still.
The chipmunk would come back, hop up two steps, scarf a pea-
nut, scamper to the same rock, and nibble rapidly, working the
nut between his paws. Our goal was to entice a chipmunk up to
the porch itself. There were six steps. One day this happened.
The chipmunk took the nut from the porch floor, only a few
feet away from where we crouched, motionless as any woodland
creature who doesn’t want to be seen.
One chipmunk became our friend. Not that exactly, but he
became identifiable when he lost his tail. In a battle with another
chipmunk? For several weeks it dragged behind him, until it
fell off. Then he became our Chippy. We were relieved to see
Chippy could climb, scamper, and scurry as well as if he had his
tail. Would Chippy be there, was the question our whole family
asked as we drove up from New Jersey each summer. Chippy
always was, until suddenly he wasn’t. My brother and I roamed
our woods hoping to encounter him. We never did.
In the evenings we walked along the road with our mother.
“That’s Indian paintbrush.” She pointed out the orange tuft on
an upright stalk. “And that’s black-eyed Susan. See the dark disk
of her eye?”
My father found our picnic spots: a field of ferns and steeple-
bush; an old woods road leading to a rushing stream. We’d bring
our bathing suits.
Our parents transplanted from the loamy woods a jack-in-
the-pulpit and a pink lady’s slipper by the porch. “Be careful
around them, children,” they said. We were because they were
so undefended and beautiful. Would they be blooming when we
arrived in June? They always were.
We made balsam pillows under our mother’s direction, clip-
ping the boughs, stripping the needles, sewing little sacks to be
filled. We took them to our winter home and tucked them in our
drawers. On days when school bore down and summer seemed
far away I would open up a drawer and release that tangy balsam
smell. Our Vermont summer would come again. The woods, the
chipmunks, the lake where we learned to swim – it was sleeping
now and waiting.
