One-flowered cancer-root (Orobanche uniflora) P H O T O B Y M I C H A E L F E D D E R

Visit us online at:www.njpalisades.org/greenbrook.htm

HAVING RECENTLY CELEBRATED THE 200TH BIRTHDAY of our “Lincoln Tree”, ourmembers became acquainted with some of Greenbrook’s oldest trees. We know

this because two scientists from Lamont Doherty Tree Ring Laboratory, GordonJacoby and Neil Pederson, determined the ages of several trees in the mid 1980’s andagain in 2003. Having just celebrated these elder residents, we became concernedwhen our oldest American elm started showing signs of disease. After locating all ofthe elms in the Sanctuary it became apparent that a disease was spreading quickly.Most of the elms are located in the southern portion of the sanctuary, but a few can befound in the northern section. Four trees growing near each other died within threeyears. From all accounts it appeared to be the result of Dutch elm disease, a fungusintroduced in a shipment of diseased wood which quickly devastated American elmsin the 1930’s. I brought the issue to our Flora and Fauna Committee and we decidedto consult with three local arborists for confirmation of the disease and treatmentoptions.

The diagnosis was confirmed and a treatment plan was put into place.Timing of the treatment was critical since the first phase had to done before the treebuds leafed out and the bark beetles became active. First we had to remove all thedead trees to minimize the spread of the fungus. For this we turned to the PalisadesInterstate Park for help. A crew was dispatched to the sanctuary in early April underthe direction of Crew Supervisors Frank Donahue and Mo Siano. Using a 60 footbucket truck and chain saws, they cut and removed the four dead elms around the pic-nic area. We would like to thank Chris Szeglin, Assistant Superintendent of the NJPalisades Interstate Park for his organizational help with this part of the project. Thenext phase of the project involved pruning the live trees and removing the dead woodfrom the canopy layer. This work was done in late April by the arborists from Sav ATree in Wycoff, NJ, who offered to donate their services to inoculate the oldest elm.The next phase of the treatment will happen in early summer when the tree is fullyleafed. The largest trees will be inoculated using a macro-infusion process that will beinjected into the base of the tree, to kill the disease and fight off future infection.

Living in a sanctuary does not protect our trees from the resurgence of diseasesand the introduction of new ones. Although we keep a watchful eye on our forest community, clearly it is not possible for us to “treat” every tree that gets sick. Our oldest elm seemed like a good candidate for treatment considering it survived the firstround of Dutch elm disease almost 80 years ago. After receiving the proposal from theFlora and Fauna Committee, the Palisades Nature Association Board of Directorsvoted to designate funds for this project, earmarking financial support for one of ourelder residents in trouble. In this case support came from many sources, including ahelping hand from a sympathetic arborist and Greenbrook member, Brice Dorwart ofSav A Tree.

Notes from the Naturalist

OUR FIRST EVENING WALK WAS WELL TIMED THIS SPRING, with breeding activity ofour earliest amphibians at peak. Members were able to see and hear (in the case

of frogs) the courtship behavior of both wood frogs and spotted salamanders in lateMarch. The results of our amphibian egg count revealed that spotted salamander num-bers seem to have stabilized in the bog and vernal pond, while wood frog numbers con-tinue to decline. Despite our best efforts to deepen and seal these ponds, our wood frogs continue to be diminished in number. This may be the result of increased predation by bull frogs, whose numbers appear to be increasing. As we continue tomonitor the progress of our wood frogs in our small nature preserve, their decline mirrors what is being observed on a global scale. See page 2 for the numbers.

The wet, cool spring was a boom for wildflowers, extending some bloomdates more than a week. Despite the rainy conditions on May 3, 40 people showed upto hike the Shore Trail in search of wildflowers. Michael Fedder had attended the wildflower hike the previous year and had good news about the rediscovery of a plantthat I thought had been lost. A small population of one-flowered cancerroot growingnear Women’s Federation Monument was recently eradicated by a beautification project. I was heartened to learn that a second population was discovered last year onthe Torrey Botanical walk along the Shore Trail. Although not an endangered species itis a rare and unusual plant of the NJ Palisades.

Birding programs tend to dominate the spring season with a variety of fieldtrips in and outside of Greenbrook . Sandy Bonardi and Ken Habermann led severaltrips to nearby sites such as Doodletown, Overpeck Preserve, Garrett Mountain andTallman State Park where approximately 70 species of birds were observed on eachtrip. Spring bird results will appear in our next newsletter.

Summer tends to be our quietest time at the sanctuary. Be sure to take a look at our almanac and find a program that fits your schedule. Remember our Sunday afternoon nature walks continue every week at 2:00 PM.

One-flowered cancer-root (Orobanche uniflora) P H O T O B Y M I C H A E L F E D D E R

Visit us online at:www.njpalisades.org/greenbrook.htm

HAVING RECENTLY CELEBRATED THE 200TH BIRTHDAY of our “Lincoln Tree”, ourmembers became acquainted with some of Greenbrook’s oldest trees. We know

this because two scientists from Lamont Doherty Tree Ring Laboratory, GordonJacoby and Neil Pederson, determined the ages of several trees in the mid 1980’s andagain in 2003. Having just celebrated these elder residents, we became concernedwhen our oldest American elm started showing signs of disease. After locating all ofthe elms in the Sanctuary it became apparent that a disease was spreading quickly.Most of the elms are located in the southern portion of the sanctuary, but a few can befound in the northern section. Four trees growing near each other died within threeyears. From all accounts it appeared to be the result of Dutch elm disease, a fungusintroduced in a shipment of diseased wood which quickly devastated American elmsin the 1930’s. I brought the issue to our Flora and Fauna Committee and we decidedto consult with three local arborists for confirmation of the disease and treatmentoptions.

The diagnosis was confirmed and a treatment plan was put into place.Timing of the treatment was critical since the first phase had to done before the treebuds leafed out and the bark beetles became active. First we had to remove all thedead trees to minimize the spread of the fungus. For this we turned to the PalisadesInterstate Park for help. A crew was dispatched to the sanctuary in early April underthe direction of Crew Supervisors Frank Donahue and Mo Siano. Using a 60 footbucket truck and chain saws, they cut and removed the four dead elms around the pic-nic area. We would like to thank Chris Szeglin, Assistant Superintendent of the NJPalisades Interstate Park for his organizational help with this part of the project. Thenext phase of the project involved pruning the live trees and removing the dead woodfrom the canopy layer. This work was done in late April by the arborists from Sav ATree in Wycoff, NJ, who offered to donate their services to inoculate the oldest elm.The next phase of the treatment will happen in early summer when the tree is fullyleafed. The largest trees will be inoculated using a macro-infusion process that will beinjected into the base of the tree, to kill the disease and fight off future infection.

Living in a sanctuary does not protect our trees from the resurgence of diseasesand the introduction of new ones. Although we keep a watchful eye on our forest community, clearly it is not possible for us to “treat” every tree that gets sick. Our oldest elm seemed like a good candidate for treatment considering it survived the firstround of Dutch elm disease almost 80 years ago. After receiving the proposal from theFlora and Fauna Committee, the Palisades Nature Association Board of Directorsvoted to designate funds for this project, earmarking financial support for one of ourelder residents in trouble. In this case support came from many sources, including ahelping hand from a sympathetic arborist and Greenbrook member, Brice Dorwart ofSav A Tree.

Notes from the Naturalist

OUR FIRST EVENING WALK WAS WELL TIMED THIS SPRING, with breeding activity ofour earliest amphibians at peak. Members were able to see and hear (in the case

of frogs) the courtship behavior of both wood frogs and spotted salamanders in lateMarch. The results of our amphibian egg count revealed that spotted salamander num-bers seem to have stabilized in the bog and vernal pond, while wood frog numbers con-tinue to decline. Despite our best efforts to deepen and seal these ponds, our wood frogs continue to be diminished in number. This may be the result of increased predation by bull frogs, whose numbers appear to be increasing. As we continue tomonitor the progress of our wood frogs in our small nature preserve, their decline mirrors what is being observed on a global scale. See page 2 for the numbers.

The wet, cool spring was a boom for wildflowers, extending some bloomdates more than a week. Despite the rainy conditions on May 3, 40 people showed upto hike the Shore Trail in search of wildflowers. Michael Fedder had attended the wildflower hike the previous year and had good news about the rediscovery of a plantthat I thought had been lost. A small population of one-flowered cancerroot growingnear Women’s Federation Monument was recently eradicated by a beautification project. I was heartened to learn that a second population was discovered last year onthe Torrey Botanical walk along the Shore Trail. Although not an endangered species itis a rare and unusual plant of the NJ Palisades.

Birding programs tend to dominate the spring season with a variety of fieldtrips in and outside of Greenbrook . Sandy Bonardi and Ken Habermann led severaltrips to nearby sites such as Doodletown, Overpeck Preserve, Garrett Mountain andTallman State Park where approximately 70 species of birds were observed on eachtrip. Spring bird results will appear in our next newsletter.

Summer tends to be our quietest time at the sanctuary. Be sure to take a look at our almanac and find a program that fits your schedule. Remember our Sunday afternoon nature walks continue every week at 2:00 PM.

One-flowered cancer-root (Orobanche uniflora) P H O T O B Y M I C H A E L F E D D E R

Visit us online at:www.njpalisades.org/greenbrook.htm

HAVING RECENTLY CELEBRATED THE 200TH BIRTHDAY of our “Lincoln Tree”, ourmembers became acquainted with some of Greenbrook’s oldest trees. We know

this because two scientists from Lamont Doherty Tree Ring Laboratory, GordonJacoby and Neil Pederson, determined the ages of several trees in the mid 1980’s andagain in 2003. Having just celebrated these elder residents, we became concernedwhen our oldest American elm started showing signs of disease. After locating all ofthe elms in the Sanctuary it became apparent that a disease was spreading quickly.Most of the elms are located in the southern portion of the sanctuary, but a few can befound in the northern section. Four trees growing near each other died within threeyears. From all accounts it appeared to be the result of Dutch elm disease, a fungusintroduced in a shipment of diseased wood which quickly devastated American elmsin the 1930’s. I brought the issue to our Flora and Fauna Committee and we decidedto consult with three local arborists for confirmation of the disease and treatmentoptions.

The diagnosis was confirmed and a treatment plan was put into place.Timing of the treatment was critical since the first phase had to done before the treebuds leafed out and the bark beetles became active. First we had to remove all thedead trees to minimize the spread of the fungus. For this we turned to the PalisadesInterstate Park for help. A crew was dispatched to the sanctuary in early April underthe direction of Crew Supervisors Frank Donahue and Mo Siano. Using a 60 footbucket truck and chain saws, they cut and removed the four dead elms around the pic-nic area. We would like to thank Chris Szeglin, Assistant Superintendent of the NJPalisades Interstate Park for his organizational help with this part of the project. Thenext phase of the project involved pruning the live trees and removing the dead woodfrom the canopy layer. This work was done in late April by the arborists from Sav ATree in Wycoff, NJ, who offered to donate their services to inoculate the oldest elm.The next phase of the treatment will happen in early summer when the tree is fullyleafed. The largest trees will be inoculated using a macro-infusion process that will beinjected into the base of the tree, to kill the disease and fight off future infection.

Living in a sanctuary does not protect our trees from the resurgence of diseasesand the introduction of new ones. Although we keep a watchful eye on our forest community, clearly it is not possible for us to “treat” every tree that gets sick. Our oldest elm seemed like a good candidate for treatment considering it survived the firstround of Dutch elm disease almost 80 years ago. After receiving the proposal from theFlora and Fauna Committee, the Palisades Nature Association Board of Directorsvoted to designate funds for this project, earmarking financial support for one of ourelder residents in trouble. In this case support came from many sources, including ahelping hand from a sympathetic arborist and Greenbrook member, Brice Dorwart ofSav A Tree.
