continues to expand! Thanks to some recent travels by our former ISA Representative/Director, Terry Flanagan, our newsletter was shared with two ISA colleagues from very distant parts of the globe!

Even more importantly, at least to your Editor, this has resulted in two unsolicited contributions to the current issue.

Mark Roberts, of Dunedin, New Zealand, contacted me with the idea of periodically submitting articles for me to consider for publication. Mark writes a regular column for his local Chapter’s newsletter and serves on the Editorial Board for ISA’s Arborist News. His fi rst article for us appears on page 5.

Don Cox, who resides in Chiang Mai, Thailand, received a copy of our Spring 2010 issue and was impressed enough by Gareth Tudor-Jones’s Safety First! article (on behaviors that lead to accidents) to sit down and write a response. This article is on page 14.

This issue also includes the usual submissions ...

the Tree Profi le from Jim • BarborinasCertifi cation Corner from Phil • Grahamthe TREE Fund Update by Wendy • Robinsonthe Book Review from Julian • Dunstera Climbers’ Tip submitted by • Robert Bundy (at the request of Rupert Evans)

As you can see, I don’t do this alone, and I probably don’t say often enough how much I appreciate the ongoing support I receive from these regular contributors, as well as Patty and Dana in the Chapter offi ce, all my fellow Board members, and of course, our advertisers. I thought it appropriate as we approach our Annual Training Conference and AGM to say it now.

So: thank you, one and all. I look forward to seeing you in Tacoma!

Directors if the new Bylaws changes are adopted at the Annual General Meeting in Tacoma. I am OK with this, not because I want off the Board, but because after 7 years as a director and offi cer, it may be better to get some new blood into the system.

Our Board historically has been composed of nurturing souls serving for 10, 12, even 14 years. The continuity and experience these individuals bring to the Board is very valuable, but we risk staying in a groove and continuing to do the same things year after year.

We have made some good strides in the past few years, but we could have done so much more. We may have been stuck in the groove, or perhaps we were limited by the size of our staff. It certainly wasn’t for the lack of some good ideas.

Despite the downturn in the economy and lighter attendance at some workshops and conferences, our Chapter is still fi nancially strong. With the right additions to our staff, and the creativity and hard work of our Regional Education Coordinators, we will be able to continue to expand the workshop offerings and services to our members.

Whether with me as Past President or with a new 5th Director, I encourage the Board to keep moving forward to provide educational opportunities to our members and outreach to the general public, work with our allied professionals at more venues, and provide new services to our members.

We must continue to provide high quality programs at the Annual Training Conference and encourage new members and climbers through our tree climbing competitions and workshops. The Tacoma ATC promises a great program at a great facility – no one should miss this meeting.

Down the road, I hope to see our Chapter do more outreach to the folks who use the services of our tree care companies and the consultants, along with the many public sector folks who manage or are decision makers that affect so many of our urban forests.

Beyond providing services to our members, the public needs to get information on a regular basis about the PNW-ISA and proper tree care. It should come from us – we are the professional society for tree care in the PNW. We are supposed to be the go-to organization.

With that said – the Bylaws change to eliminate the Past President offi ce should be good. A 5th Director should allow us to channel new blood through the Board.

Come to the Annual General Meeting in Tacoma and vote on the Bylaws changes. If you think the change to the 5th Director is the way to go, support the change. If you would like to see the 5th Director position be focused on something other than Governance, express yourself to the Board with an email or in person, and/or offer an amendment at the AGM.

It has been an honor to serve the Pacifi c Northwest Chapter of ISA for 7 years. Now let’s get on with improving the quality of tree care in the Inland and PNW. Our kids, grand-kids, and generations to come deserve our best efforts. Like I said in the past, go out and plant a heritage tree today. If we don’t plant it, it won’t be there in a hundred years.

FROM THE EXECUTIVE DIRECTOR’S DESK

BY THE TIME THIS newsletter reaches you,

Patty WilliamsExecutive Director

"He that plants trees loves others beside

himself."

~ Thomas Fuller

you should have already received a draft copy of amendments to the PNW-ISA Chapter Bylaws, our governing documents. In February 2010, a committee was formed by the Board of Directors to review the Bylaws.

The committee submitted recommended changes to the full Board of Directors in May and again in July for fi nal approval. The Board of Directors will now present these proposed changes to you, the PNW-ISA membership, at the Annual General Meeting in Tacoma, September 29, 2010.

Some changes were made to punctuation and grammar throughout the document for clarity and consistency. Three (3) changes, however, impact membership dues and continued Chapter leadership.

Last year, ISA provided an option for two-year memberships. While chapters were not afforded the option before the ISA change, the PNW-ISA Board of Directors agreed that our

governing documents should mirror ISA in this regard. As of this writing, it is unclear whether the Chapter’s two-year option will be available in 2011 or 2012. Regardless, the change in Bylaws would allow the option. One-year memberships would still be available as well.

Two substantial changes to the Bylaws have an immediate impact on board leadership roles and opportunities. The amended Bylaws would 1) eliminate the position of Past President from the Board of Directors and 2) add a Governance Director as an elected position with term limits.

The Past President position was originally intended to be a mentor to the incoming President. Since the incoming President will have been on the board for at least two years prior as President-Elect and often as many as six years given other board positions, the need for mentoring has been greatly reduced. Changing technologies and demographics have also shown board volunteers requesting shorter time commitments.

Eliminating the mandatory two-year Past President term is expected to generate increased interest in board service. The new Governance Director position is intended to help compile and manage policies and procedures related to consistency and best management practices.

Of Note: The Summer 2010 newsletter contained several articles and columns on plans to address the Chapter’s future staffi ng needs. At the July 2010 board meeting, the Board of Directors agreed that the recommendations I made in May 2010 were somewhat premature and require a more concerted effort time-wise to ensure the Chapter’s long-term organizational health. Due to time constraints and the pending conference, plans are to revisit the staffi ng issue after the Annual Training Conference.

THIS TIME LAST YEAR, THERE STOOD a beautiful oak tree in our local Botanic Garden. It was a commemorative oak with a plaque and a listing on the notable tree register. It was a grand tree, but now it is not. There now stands some sort of sculpture created by Spiderman – if Spiderman were to do sculpture. A twisted and broken tree interconnected by a web of synthetic cables.

The tree had been cabled; old school wire and eyebolts once connected all the main limbs. And at some stage over the past 12 months, the tree was pruned, the old cables were removed, and the tree failed (and then what was left was then re-cabled). There is, of course, more to it than that but that’s another story.

Without the old cables the tree simply collapsed under its own weight – it just didn’t know how heavy it was. In fact, it didn’t know anything; it is just a tree, it doesn’t think. Trees (plants) just respond to what is happening to them or around them. In this particular instance, because the fi rst set of cables supported the weight of the limbs, there was no need for it to set down any supporting tissue. The response was not to respond. When the cables were removed it responded by collapsing.

Without the initial set of cables the tree would have produced adaptive growth in the form of reaction wood to support the limbs, or lost them (all or part thereof). Reaction wood forms when part of a tree [woody plant] is subjected to mechanical stress. It is set down at a specifi c point in direct response to loading at that point. The process is exact and the tree will not invest more growth than it needs to strengthen that point. Trees and woody plants do this – so the theory goes – to create and maintain uniform stress.

There are a couple of weighty concepts more common to other disciplines tied up in that paragraph [adaptive growth; medicine and bones, uniform stress; engineering and design] but keeping with trees, it’s the production of reaction wood that I wish to draw out.

Reaction wood can be divided into compression and tension wood. Angiosperms (hardwoods) produce tension wood on the upper side of the stressed area, effectively applying a pulling force to support the limb. Gymnosperms (conifers) produce compression wood on the under side of the stressed area, effectively applying a pushing or holding force to support the limb.

The placement of reaction wood is very exact, and if the point of mechanical stress remained equally as exact then strengthening that point should be simple. But the external forces that create mechanical stress can be varied and compounded; also, as a limb grows in weight and shape the [mechanical] stresses also move by default. Because of this, the production of reaction wood needs to be thought of as a constant – a work in progress if you like.

When we reduce the weight of a limb, for whatever reason, we change how and where that limb is loaded – we change the position or positions of mechanical stress. The majority of the time, but not always (assuming the right sort of cuts are made in the right place), the redistribution of loading or the effective loading is moved to a point down the limb that is suffi ciently strong.

When we support the weight of a limb with a cable, the same thing happens; we change how and where that limb is loaded. But where that load is redistributed is very different.

A proportion of the load will be transferred to the anchor point (anchor loading) and the rest will be distributed elsewhere forwards and backwards along the length of the limb. Assuming the tree is healthy and vigorous, it will respond to these new loads by producing reaction wood where needed. But if it is not, well that’s another story.

Once we start guessing the effects of load distribution and redistribution of supporting (load-bearing) cables we begin to weave a wicked web which only your cable supplier will thank you for. The only thing equally hard to second guess would be load distribution on limbs after the supporting cables have been removed.

So what do you do if you have been asked to re-cable a tree?

Knowing that every tree and every situation is slightly different, there can be no single answer to this question. If you fi nd yourself faced with an old load-bearing cable that needs replacing, then you are going to have to make a call based on your knowledge and experience. My thoughts are that you should think of it as part of the tree more so than some after-market or post-production installation. I’d be tempted to put a new cable in where the old one was, and respond to any new cabling needs or issues separately. If the old cable was under tension then the new cable also needs to be under tension (the same tension).

If you are putting in new cable to serve a new issue, i.e., not replacing an existing or old cable, then set it so the tree can experience stress; controlled stress, but enough so the tree can respond to it.

Update from the TREE FundNEWS FROM CHICAGO

THE 2010 STIHL TOUR DES TREES has come to a close. The Tour des Trees is the largest non-governmental funding source for tree research in America. The 2010 tour has raised over $365,000 to date (donations were accepted until August 15th).

The PNW Chapter had four riders this year: Phil Graham from British Columbia and Terrill, Logan, and Brandon Collier from Oregon. To ride in the tour, a rider must commit to raise $3,500. Congratulations to all of them for doing us proud on the Tour, and thanks to all who sponsored them. As an added bonus, the money raised to support the PNW riders counts towards the year-end fundraising Chapter Challenge. Support tree research, support the PNW Chapter!

The 2010 TREE Fund Gala Auction in Chicago was also a success. There were many great auction items this year. The PNW package, which included a week on the scenic Olympic Peninsula, raised $1,600 for tree research. In all, the event raised nearly $50,000.

CHAPTER AUCTION DONATIONS NEEDED!

THIS YEAR’S PNW CHAPTER Auction will be held in Tacoma on September 28th. If you would like to contribute an item to either the silent or live auction, please contact Wendy Robinson, your TREE Fund Liaison. Send an email to wrobinson@ci.bend.or.us or give her a call at 541-388-5598. Be creative – no item is too big or too small!

PNW Tree Profi le

IT IS NOT SURPRISING THAT ELMS enjoyed immense popularity so many years ago. They literally grow like weeds, and they recover from crown damage exceptionally well. However, the proliferation of Dutch elm disease eventually put a stop to this tree’s popularity, resulting in the physical removal of this species from most streets and recommended street tree lists. Despite the degraded reputation elm trees endured for so many years, recent research and breeding programs have given them new life. The challenge now is to know which elm cultivar to grow, or plant, given the many new varieties that are slowly reaching the market.

We actually began growing Triumph Elm by accident, having received the tree in a shipment of the highly favored Accolade Elm, Ulmus japonica x wilsoniana ‘Morton’, that we had ordered. From our experience, the Triumph Elm is worth a serious look as an addition to your planting list.

The Triumph Elm is a fast growing tree, reaching nearly twice the size of other trees in the same fi eld planted the same year. The form is upright oval to vase shape. The summer foliage is glossy dark green, changing to a bright yellow in the fall, much like

the American Elms some of us may remember from the Midwest, as well as a few still growing around here.

I am most impressed with the ascending limbs and favorable branch attachment on the majority of trees I have seen. The structure is reminiscent of the large old upright elms, with the tall broad canopy that enhances character and adds a sense of longevity to established neighborhoods. The leaves are slightly smaller than the American Elm, but to some, the smaller leaves are actually more desirable.

This is a Dutch elm disease resistant tree, drought tolerant, and resistant to elm yellows and the elm leaf beetle. This tree, like most elms, transplants easily and tolerates severe pruning if needed.

Surprisingly, some evaluators described this tree as ‘ugly.’ However, I would suggest that, as with many trees, there is regional variation in its performance. While visiting the Morton Arboretum several years ago, I observed several tree varieties that are very impressive in the Pacifi c Northwest, but I found them rather ‘ugly’ in the arboretum. Dr. George Ware, the Elm Tree expert onsite, agreed with this regional variation and emphasized the importance of testing tree performance in many locations. Personally, I have found the Triumph Elm to be a worthy tree to consider planting in the Pacifi c Northwest.

Let me know if you have any experience with this or other elm varieties.

Book Review

THE WORLD OF TREES CAN AT TIMES be remarkably boring when we get wrapped up in the technical trivia of arboriculture and urban forestry. It becomes easy to forget that we are dealing with living plants, each having its own unique character. Cedric Pollet’s new book takes us away from the technical aspects and leads us back to the sheer beauty of seeing trees, and especially the artistic nature of tree bark.

Pollet, C. 2010. Bark: An Intimate Look at the World's Trees. London: Frances Lincoln Limited. pp. 192. ISBN 978-0-7112-3137-5. US $45.00.

Eighty-one trees from around the world are displayed with high quality colour images. Each has a brief description, along with a sense of what attracted the author to them. If you like photography and trees, then this is a book for you. The images are well done and capture the essence of the magic and mystery of trees. An excellent coffee table book, and a good Christmas present!

URBAN TREES RESEARCH CONFERENCE

APRIL 13-14, 2011BIRMINGHAM, UK

CALL FOR PAPERS

URBAN TREES AND WOODLANDS ARE essential elements of our green infrastructure and have a vital role in promoting liveable and sustainable towns and cities. As concern grows about the sustainability of our urban environments, the importance of protecting and expanding our urban forests can only increase.

The main aims of this research conference on urban trees are to identify completed research that remains relevant, research being undertaken currently, and gaps in research where future efforts need to be focused.

Papers are welcomed that address any topic involving trees and the built environment, in both the social and natural sciences.While many papers will focus specifi cally on the UK, the conference will have an international perspective and papers from overseas authors are welcomed.

Authors whose papers are selected will be invited to present their work at the conference. Presentations will last no longer than 30 minutes. It is expected that presented and accepted papers will be peer-reviewed for an edited book.

Authors wishing to respond to this call should send an abstract of not more than 1,000 words to be received by 12 noon GMT on 1 November 2010.

For more information, visit: www.charteredforesters.org/conference/ or contact Dr Mark Johnston, Myerscough College, at mjohnston@myerscough.ac.uk.

Around the Chapter

THE CITY OF VANCOUVER HAS TAKEN on the challenge of becoming the Greenest City in the World by 2020.

As part of the program, city staff have formed 10 working groups to look at new policies that will help them achieve this goal. The city has also started a “Green Conversation” program where staff and the public can suggest policy options and vote on the ones that they like.

We at DeepRoot would like to support this initiative with our own proposal: that Vancouver follow the lead of other cities like Charlotte, NC, Emeryville, CA, Toronto, ON, Langley, BC, Markham, ON, and Winnipeg, MB and introduce mandatory soil volume standards for street trees.

The research is very clear: cities need large, mature trees.

In order to get the benefi t and value of large mature street trees – better air and water quality, higher home and business values, and safer streets (to name just a few) – they need adequate soil volumes to nourish their growth.

Most trees being planted in urban environments have access to only a fraction of the soil they need to grow to maturity, in some cases as little as one-tenth of the required amount. As a result, these trees never grow to make a real ecological or aesthetic impact on their communities.

By setting mandatory soil volumes in the tree planting specifi cation, the City of Vancouver will ensure that we get the maximum ecological, aesthetic, and fi nancial value from our street trees. It will give power and a voice to all the citizens who want to see their built

VANCOUVER, BC – GREENEST CITY IN THE WORLD BY 2020

COLLIER ARBOR CARE HAS BEEN chosen to participate in an international pilot program testing the nation’s rating system for green landscape design, construction, and maintenance.

Collier’s four-acre site on SE Jennifer Street in Clackamas, OR, is one of 175 pilot projects from 34 states, Canada, Iceland, and Spain as part of the program designed to evaluate the new national uniform Sustainable Sites Initiative (SITES) rating system for sustainable landscapes.

The SITES system has been devised to provide a road map leading to LEED certifi cation for an overall site, expanding the Green building rating systems beyond the buildings’ skins.

Collier’s initial Jennifer site development, which abuts Carli Creek, included replanting and creation of a conservation corridor along the creek and installation of bio-swales to collect run-off water from parking lots and the two buildings on the property.

environment become literally, and not just metaphorically, greener. It means that we can ensure that we’re getting the big, gorgeous, ecologically signifi cant trees on our streets that we want.

We are asking for your support for this proposal and participation in the GREEN2020 conversation. Vancouver’s Street Tree Plan can be a model to other cities in the Pacifi c Northwest. You do not need to be a resident to vote.

To Vote: Go to: http://vancouver.uservoice.com/forums/56390-gc-2020. Search for “mandatory soil volumes” and click to vote!

Thank you for your consideration and support!

By, Michael James, DeepRoot Canada Corp., Vancouver, BC.

Under the pilot program the fi rm will retrofi t the property’s irrigation system, re-develop the bio-swales into a rain garden, and replant the conservation easement with native shrubs to make it a mini-arboretum. The fi rm also will use 100 percent organic products for weed and pest control and for plant maintenance and soil health.

Although not part of the SITES project, Collier Arbor Care is in the process of installing solar panels. It is seeking an Eco-Biz designation from the Pollution Prevention Outreach team, a group of pollution prevention experts from seven agencies in the Portland metro area. Ultimately, Collier hopes to obtain LEED certifi cation for the site.

The Green Cities Research Alliance (GCRA) is a new science initiative sponsored by the USDA Forest Service, PNW Research Station. The purpose of GCRA is to study the connections of human and natural systems across the landscape gradient. Studies include urban to rural landscapes of the Pacifi c Northwest, but with a focus on cities and towns, as more than 80% of the region’s residents live in urbanized areas. Early studies are focused on environmental stewardship – as in-depth studies of grassroots activities and programs on the land, and their social and ecological outcomes. The project hopes to learn about how fi scal and technical resources can be directed to stewardship programs to achieve ecosystem health and recovery. More information can be found at: http://depts.washington.edu/gcra/index.shtml.

Safety First!SAFETY: ATTITUDE FIRST

RE: THE ARTICLE, “SAFETY FIRST!” by Gareth Tudor-Jones of Bartlett, Pacifi c Northwest Trees, Spring 2010.

I was pleased to see that a “Safety and Training Coordinator” for a major company has the intelligence and obvious experience to understand that safety is not all about PPEs and ANSI and laws and regulations, but largely about the psychology and behavior of the worker.

I am inspired to take it a step further and write about my take on the subject, and to maybe share my secret of success, it you can call it that. Who am I to write about safety? Well, maybe just an old tree worker; but with one claim to fame: a hard-to-beat safety record – no major injuries or property damage by me or any crew member in over 40 years of tree and landscape work and crew management. It is for this record that I would ask for a moment of respect from whoever reads this; I may be able to offer a perspective that could save a life, or at least save some pain and grief, and money.

It’s not that I’ve never done anything stupid or been lucky, the Lord knows I’ve gotten away with some idiotic moves at times and lived to tell about it. But I have learned from my mistakes and the mistakes of others as best I can.

It’s all been said; safety is a many-sided subject with several major issues to consider. In my articles written for TCI magazine in 2003 (“Health and Productivity, The Tree Worker as a Professional Athlete” and “Horror Stories, The Essence of Safety is Fear”), I covered some issues that I feel are important, above and beyond the PPEs.

Gareth’s article is right on! And any tree worker, foreman, or manager of tree workers would be a fool to ignore his important observations. These psychological and behavioral issues are the core of safety awareness.

But something that he did not have the space to go into much, and I feel is as important as anything in the realm of safety, is the aspect of responsible management attitude and behavior.

The managers tend to blame the workers for accidents and not look to themselves for what they could have done better to prevent injuries, auto and equipment accidents, and property damage. They schedule the training, the tailgate sessions, they have rules, they provide the PPEs, they maintain equipment, etc., but accidents still happen.

A lot of it has to do with the pressure for production and how they handle it and how much of the manager’s stress to get the jobs done and make things work fi nancially is passed on to the crew in a negative way.

You have zero tolerance for drugs and alcohol on the job, for no-call no-show, for not wearing hard hats, etc., etc.? How about including zero tolerance for anger, yelling, blaming, not listening, disrespect, and pushing your crew beyond a reasonable level of healthy production expectations? It’s you who underbid the job, not your climber; don’t pass on your stress over the matter and cause an accident.

From Health and Productivity, The Tree Worker as a Professional Athlete: “In addition to safety equipment and training, it should be recognized that healthy and well-managed workers avoid extreme fatigue and diminished capacities in strength, alertness, and patience. An exhausted worker needs to report his condition, the foreman needs to see it and deal with the situation accordingly before it becomes a problem. You can only push a human body so far before it breaks down. An exhausted player can throw the game just when you really need a win.

“Do you have a team composed only of fi rst-string players whom you are pushing to the limit all week long, and then expecting them to come back strong on Monday? How long do you think that will last? Or do you wisely manage your crew with measured, staggered duties, as a coach would do with a second string to relieve fatigued primary players when appropriate? Think about it, a crew of tree workers is a lot like an athletic team with many of the same needs in comprehensive management, health and lifestyle education, injury treatment, motivation, and all-around supportive leadership.

“Crew managers need to recognize and support the athletic nature of what their

workers do, provide an example of healthy and sane living, educate and manage their tree work team the way a good coach would manage a winning athletic team. The results can be a safer and more productive work force and a better experience for everyone.”

From Horror Stories:The Essence of Safety is Fear: “Areas of safety neglect: One is health. A healthy worker who eats right, sleeps well, and takes care of himself like the professional athlete that he needs to be, will be more alert and attentive to what he is doing. And he will be strong and agile enough, and have the stamina to make it through the day. Wellness education should be part of a comprehensive training program.

“Another area is management for health and safety. Too many managers and foremen set bad examples with unhealthy lifestyles and poor safety habits on the job. If a foreman or a supervisor doesn’t wear his hardhat, how can anyone expect the rest of the crew to wear theirs? If a manager drags in red-eyed and grumpy on Monday morning after a binge weekend, what do you think that says?

“Patience, guidance, good examples of safety, and time management are important keys to safe tree work. Sure you have to push to get the job done, but it must come from solid teamwork, good attitude, health, strength, leadership, good training, good equipment, and professional effi ciency.

“A third area of often neglected safety awareness is thoroughly reviewing accidents and near accidents that your company has; like a football team reviews game tapes, objectively analyzing each movement, talking about what went wrong and what they could do better next time. And sharing the information gained with everyone on the team so the same mistake doesn’t happen again. And this includes really getting the point across about what are the worst-case scenarios. A crew may fall asleep during a safety meeting; they’ve heard it all before. But tell a horror story and I bet you’ll get their attention. And I bet they won’t forget it.”

Certifi cation Corner

By Phil Graham, Certifi cation Director.

IN THE LAST ISSUE I SAID I WOULD focus on the foundation of our industry, the tree worker. I wanted to wait until this issue because I was scheduled to participate in evaluator training for the Certifi ed Tree Worker, Aerial Lift Specialist program in Portland on May 20th. For me, this was a great chance for a brief immersion back into the world of the people who get the work done in this business, and a bit of a reminder of the tremendous amount of skill required to do tree work. Derek Vannice from ISA and Dave Sexton from the Rocky Mountain Chapter worked with our own Terry Flanagan to train Brian French, Dave Gaugel, Dennis Matlock, Chris Boza, Steve Markel, Scott Clifton, and me. Collier Arbor Care provided a lift for us to use for the day. It was great to see everyone come together with the common purpose of not only learning to be good evaluators, but also giving feedback to help the program continue to improve.

The Aerial Lift Specialist is the most recent addition to the Certifi ed Tree Worker portfolio. Now, a worker can write the written exam to demonstrate the knowledge that is common to both climbing and aerial lift operation, and perform the practical test in either or both disciplines. Certifi cation as a Tree Worker should be important to the worker as proof that they have demonstrated their knowledge and skills to a measurable level. Employers can be confi dent as well that their workers have demonstrated that level of knowledge and skill. Finally, municipalities and utilities are beginning to see the importance of having their tree work performed by certifi ed workers. We are starting to see the requirement for certifi cation written in to municipal codes and utility contracts. I hope it is the beginning of a groundswell that eventually sees certifi cation as the accepted norm for tree work of any type.

Here in the Pacifi c Northwest, the challenge is to build both the Tree Climber and Aerial Lift programs in a sustainable way. We are faced with huge distances, a widely scattered tree worker population, and the realization that there is a lot of time, money, and effort in putting on a practical test. Set-up of the trees and evaluation of the workers is all volunteer based, and this is a huge commitment on their part. Typically, we try to schedule tests at the Annual Training Conference, and a climber has the opportunity to use a regional climbing competition as a practical test. But not everyone wants to be on display in the competitive arena, so we need to look at setting up tests either just prior to a climbing competition, where we

can take advantage of the tree set-up, or completely independently, realizing that it will take more work.

That is the Catch-22. Given the time and effort to set the tests up, we want to be sure there are enough candidates to make it worthwhile. If we don’t get enough interest, we don’t set up the tests, and if we don’t set up the tests, we don’t get the interest. My goal is to move towards a number of set tests throughout the PNW. That way, the dates and locations will be scheduled well in advance, and maybe then we’ll get enough interest to justify the set-up. I’ll be asking for your patience as we move towards that goal.

A GIANT SEQUOIA, LOCATED IN downtown Seattle, marks the main entrance to Seattle’s downtown retail core. Growing in a median triangle formed by the intersection of Fourth Avenue and Olive and Stewart Streets, it is notable for its very large size and for the festive role it assumes during the winter holidays when it is draped with colored lights. With the once beautiful tree declining in health in recent years, and its top damaged by heavy winds, Seattle Department of Transportation (SDOT) Urban Forestry asked the question: can such a tree survive in its current environment of pavement and exhaust produced by heavy traffi c?

Retrofi tting in and around hardscape is never an easy task. However SDOT, in consultation with inter nationally-known landscape architect James Urban, has undertaken a soil renovation project in an attempt to save the tree.

Urban is well-known by arborists as the author of “Up By Roots,” which advocates for larger soil volumes, often including engineered solutions and structures, to accommodate root growth of trees in built (urban) environments.

SDOT’s save-the-sequoia project involved improving the soil, both at the surface and deeper under ground, to allow more water and air to penetrate, and to provide a larger area of suitable soil which will continue to support the growth of the tree. An “air spade” in tandem with a “vactor truck” carefully excavated and removed soil, creating three-foot deep voids that were then fi lled with compost. The air spade was used to aerate the surface soil, followed by an application of duff (organic material salvaged from the surface beneath healthy trees of the same species) placed on the surface to ensure correct microbiology is achieved in the imported soils.

In future weeks the Urban Forestry staff plan to follow up with work on the broken top to encourage the development of a new central leader at the top of the tree.

Assuming the tree shows improved vitality over the next couple of years as a result of this treatment, SDOT has expressed an interest in a second phase, with input from Urban, to further expand the volume of soil available to the tree under the adjacent sidewalk and street pavement.
