Is that tie-in point safe to use?...

By Brian Kane, PhD, Massachusetts Arborists Association Professor of Commercial Arboriculture at the University of Massachusetts – Amherst

Figure 1 shows the Straightpoint LLC load cell used to measure forces during the Ascent event at the 2017 ITCC in Washington, DC.

Tree climbing is an inherently dangerous task. Working at height is dangerous by itself; but add the use of sharp cutting tools and rigged pieces of wood to the job, and it’s not surprising that our industry has a comparatively high incident rate. To increase safety while climbing, climbers must choose a tie-in-point (TIP) that can bear the loads applied as the climber ascends and then works in the tree. Failure of the TIP isn’t an everyday occurrence, but it has happened, even during an ascent. To reduce the likelihood of failure of the TIP, climbers attempt to assess its load-bearing capacity by visual inspection and performing a “bounce test,” but very little research has explored the likelihood of TIP failure.

In 2017, at the ITCC in Washington, DC, I measured forces at the TIP during the “Ascent” event – this is the event that replaced the secured footlock. From the measurements, I wanted to learn how large were the forces at the TIP, what was their frequency of application, and whether they differed among different ascent techniques that competitors used. Most competitors used two foot ascenders, but some footlocked and others used a single foot ascender.

To measure forces, the team running the Ascent event installed a load cell between the anchor point on the tree and the rigging hub that climbers attached their lines to. The load cell (Figure 1), made by Straightpoint LLC, measures the force 100 times each second, so it’s possible to obtain a detailed record of the forces throughout each competitor’s ascent—this is called a force time history. Figure 2 shows the force time history for a ten second segment of one competitor’s footlock—it might remind you of an EKG. The time history shows a series of peak forces as the climber extended their body upwards after locking the rope with their feet. The peak forces occur at regular time intervals, which describes the frequency of peak forces, that is, how many peak forces occur in a specified time interval. Using two foot ascenders applied about the same force as footlocking, but at twice the frequency—twice as many peaks in the same time interval.

Figure 2 The black line shows changes in the load on an anchor point during ten seconds of an ascent.

To assess the likelihood of failure of a TIP during an ascent, we need to know both the amount of the peak force, and how frequently it’s applied. The reason for this is because as its loaded by the ascending climber, the TIP bounces up and down. The interaction of the repeated application of peak loads with the natural tendency of the TIP to respond by bouncing may cause the effect of the force to be multiplied. This means that even if the peaks are well below the load-bearing capacity of the TIP, the bouncing action can increase the likelihood of failure.

In general, peak forces were about 1.3 – 1.4 times body weight, and, depending on how long the ascent lasted, there could be 20 – 50 peak loads in total. This type of loading on the TIP is very different from slowly applying a force with a winch to a branch to measure attachment strength of branches, indicating that future experiments should consider applying forces to the TIP that would mimic the forces applied during an ascent.

This work wouldn’t have been possible without a John Z. Duling grant from TREE Fund, which paid for the Straightpoint, LLC load cell. One of the limitations of the data collected at the ITCC is that the TIP was atypically large (which was a necessary safety precaution when more than 60 competitors would be ascending during the event). To address this limitation, and using the same Straightpoint LLC load cell, I am currently measuring forces during ascents on TIPs of typical size. And I plan to repeat those measurements when the trees are leafless to see how much of an effect the leaves have on damping the bounce motion of the TIP. With funds from the Duling grant, I also purchased two Straightpoint LLC “Impact Blocks”—arborist rigging blocks with built-in load cells—to measure forces in rigging systems, which I have been doing this summer. I think these projects, and others I’ve worked on that TREE Fund has previously supported, will help arborists work more safely, and I’m grateful for TREE Fund’s support.

Behind the Research: Meet Dr. Brian Kane

 

Behind the Research: Meet Dr. Brian Kane...

It’s the first day of school at the University of Massachusetts, Amherst, and Dr. Brian Kane is back from sabbatical. Amid the flurry of campus activity, Dr. Kane takes a break to talk about his background and work with me. Dr. Kane, the Massachusetts Arborists Association Professor of Commercial Arboriculture at UMass Amherst, is a leading figure in arboricultural biomechanics and tree worker safety, focusing his research on tree failure and gear failure. With his unassuming, casual manner, it’s surprising to know that he is one of very few people who study this complex area of the physics underlying tree failure and arboricultural practices like pruning, cabling, rigging and climbing.

Brian grew up outside of New York City and remembers his early interest in trees was piqued by his dad’s Audubon Tree Guide book. He ran a landscaping business as a kid and loved climbing for a local municipal tree crew, but it took a degree in Political Science and an unsatisfactory desk job before he realized that the one constant throughout his life was that he liked trees. So he enrolled at UMass Amherst for a masters in Arboriculture and later a PhD, and he hasn’t looked back since.

At the start of his academic career, Brian was interested in the strength loss formulas that predicted the likelihood of tree failure based on how much decay existed in the trunk and branches. The formulas were theoretically sound, but had not been tested for reliability in real life scenarios. What he discovered was that the formulas did not take enough variables into account for such a complex assessment. His work played a role in the development of ISA’s tree risk assessment qualification (TRAQ), which has helped to make the risk assessment process more objective.

Brian’s current work is focused on arborist safe work practices where there is a deficit of research. Specifically he’s exploring the forces that occur (1) when a climber ascends into a tree and (2) in different parts of a rigging system. Because there are so many variables that affect the likelihood of tree failure and many different climbing and rigging techniques and tools, it’s virtually impossible to come up with a formula for the safest way to climb or rig every tree. Dr. Kane sees his work as laying the groundwork for safety improvements by helping us understand the physics underlying rigging and climbing. This knowledge allows us to identify the key points or variables for improved safety or reducing the likelihood of failure.

As you might imagine, conducting arboricultural biomechanics research involves everything from people climbing trees to crunching physics and math equations. Dr. Kane emphasizes that his work is a collaborative effort, and he is grateful for all the help from his students, alumni, colleagues in the university’s Engineering school, etc. And he’s also happy to use himself as a test subject – just another reason to continue climbing trees after all these years.

Leading Thoughts (September 2018)...

By J. Eric Smith, TREE Fund President and CEO

As the leaves begin to color and drop here in Northern Illinois over the next few weeks, we will be rolling out our individual year-end fundraising appeal, as hard as it is to believe that the end of the fiscal year is already drawing near. We’re on track for another great year in 2018, but the unrestricted operating funds earned via the year-end appeal are crucial to our ongoing success, so my thanks to all in advance for considering us in your charitable plans in the weeks ahead.

The “charitable” component of that sentiment is more important than usual this year, as many of you are no doubt evaluating how changes in the Federal tax code could impact the deductibility of your gifts to TREE Fund and other nonprofits. While TREE Fund is not in the business of providing financial advice, we do know that many of you may find it financially beneficial this year to use the increased standard deduction in lieu of itemizing your deductions (including charitable giving), which will reduce the strictly financial tax return benefit you receive from each dollar of your charitable giving in 2018.

I respectfully hope, though, that you do not change your giving plans for that reason, since the charitable good you do for TREE Fund is actually independent of any quid pro quo tax benefit you receive as a result of your philanthropy. Charity is, by its very definition, the voluntary giving of help, typically in the form of money, to those in need – and TREE Fund does indeed need your continued support if we are to build on and expand our research and education programs going forward, especially as Federal funding for urban forestry may decline in parallel with lower revenues from Federal taxes.

TREE Fund is a charity, at bottom line, worthy of support for the good work we do, and for the benefits that our research and education results deliver to communities around the world. It is only through your charitable support that we are fully able to be a force for good in the world, funding vital, beneficial work that few others do. I’ve spent most of my career in the nonprofit sector, and I know that when push comes to shove, that sense of doing something righteous, and making a difference through your gifts, is the truly fundamental motivator for donors, one that resonates deeply in ways that simple monetary benefit from tax deductibility cannot.

Here’s hoping you share that sentiment with me, and that we can continue to count on you to do good for a good cause this year when you receive a letter from me asking for your support in the weeks ahead. You may or may not receive a meaningful tax benefit from giving to us this year, but the moral and ethical benefit of sharing your resources openly and without restriction on behalf of TREE Fund or other charities you respect is profound and lasting. At the end of the day, it’s simply a good thing to do – and I remain personally committed to ensuring that we leverage your support widely, and serve as responsible stewards for funds entrusted to our care.

 

Your voice on the future of arboricultur...

TREE Fund’s booth at this year’s International Society of Arboriculture Annual Conference in Columbus, OH, centered on “The Future of Arboriculture,” so booth visitors were asked to vote for the topics they feel are most important to the future of arboriculture.

Given that tree care is a dangerous field, it’s not surprising that safety, including workforce practices, tree biomechanics, and risk assessment and management was seen as the number one area on which to focus. Right behind safety was the foundation of arboriculture – roots and soil research. Participants also cited climate change and extreme weather as an important factor impacting the future of the field. Rounding out the top five responses were pests/invasives/diseases and the labor challenges the tree care industry currently faces, including recruiting, training, and engaging women in the workforce.

The good news is that TREE Fund research and initiatives are right in line with these priorities. You can find studies and resources related to each topic by clicking the links below.

  1. Safety/biomechanics/risk assessment and management – In addition, the Frank E. Gamma, Sr. Arboriculture Education Fund supports workforce safety training through TCIA’s Arborist Safety Training Institute.
  2. Roots and soil
  3. Climate change and extreme weather
  4. Pests/invasives/diseases
  5. Workforce – Many of our Arboriculture Education Grants have funded programs designed to get youth outdoors and interested in careers in tree care. Our scholarships support students training for work in arboriculture and urban forestry. The Collier Arborist Training Trust Fund has been established to foster, promote, and support the teaching of practical applied arboriculture.

Thank you to all who participated in the voting!

Leading Thoughts (August 2018)...

By J. Eric Smith, TREE Fund President and CEO

When I was hired as TREE Fund’s President and CEO three years ago, I was asked to provide some biographical information to help our supporters get a sense of who I was and what I was bringing to the organization. One of the questions posed – “What’s your favorite tree?” – seemed to be a simple one, but it actually was and remains something of a stumper for me. 

How do you answer that question, really? As a tree lover (or tree nerd, per my family), it’s a challenge right up front to decide whether to pick a single species, or a single individual. I lived in Latham, New York for nearly 20 years, and there was one huge white willow tree (Salix alba) in my neighborhood that I adored every time I passed by it, but if I picked
that one, then it wouldn’t be meaningful to anybody outside of Latham. In my column here two months ago, I wrote about a longleaf pine (Pinus palustris) at my childhood home that was wrapped tightly with wisteria vines. I loved it dearly as a kid, but know as an adult that it was a poorly located mess, just begging for removal.

So picking individual trees is probably a bad idea for media purposes, but is picking a single species any easier? My opinions change by the minute, depending on where I am or the time of the year. Right now in Chicago, I am loving the swamp white oaks (Quercus bicolor), and I can’t resist reaching out and stroking their leaves when I walk past them; shiny and leathery on top, fuzzy and soft on the bottom, just wonderful for tactile people like me. But a month or so ago, as I was training for the Tour des Trees, the American Lindens (Tilia Americana) were in bloom, and their
tiny sweet flowers were like giant collective air fresheners for the city, making my riding experience more deliciously fragrant than is normally the case in a huge city like mine.

How could I pick one of those species over the other? Or over the one that moves me the most next month, or in the next city I visit? Honestly, I couldn’t, and can’t. But three years ago, I felt like I needed to give some answer to that seemingly innocuous question, lest I come across as difficult to our staff, so I picked the Southern live oak (Quercus virginiana), the tree most closely identified with my Low Country South Carolina roots. (Well, other than our State tree, Sabal palmetto – but that’s technically a grass). So that’s what the record shows, and it’s a reasonable answer, I guess, but I am reserving the right to change it, today, tomorrow, and any time in the future.

2018 TREE Fund Research Grant Recipients

Hyland R. Johns Research Grant

Andrew Hirons, PhD (Myerscough College, UK) and Co-Investigator Henrik Sjöman, PhD (Swedish University of Agricultural Sciences, Sweden) aim to improve tree selection for stormwater management schemes and sites prone to waterlogging. In the study, “Enhancing the performance of urban storm water management schemes with tree selection: developing a new approach to accessing waterlogging tolerance in temperate trees,” Drs. Hirons and Sjöman will look at trees’ decline in sapflow under waterlogging and use this to quantitatively evaluate waterlogging tolerance. Data will be collected on the species’ drought tolerance as well. This combination of data will provide guidance on which species will perform best in these situations.

Safe Arborist Techniques Fund Grant

Alexander Laver (Tree Logic, working with Coventry University, UK) will use motion capture equipment to map the movements of a tree climber within the canopy of a tree. “Optimised techniques for arboreal activities” will then analyze the effect of different climbing methods on the climber’s body. The goal of this project is to be able to recommend best climbing methods that can keep climbers fit and healthy for a full and long career.

 

Utility Arborist Research Fund Grant

John Goodfellow (Bio-Compliance Consulting, Inc.) will supplement his previous work on constructing an economic business case for Integrated Vegetation Management (IVM) on electric transmission rights-of-way (ROW) in this new study called, “The cost-effectiveness of integrated vegetation management.” This project will consider the many benefits of IVM, and will result in a more holistic assessment that includes both economic considerations and environmental externalities associated with IVM. The project will also include application of IVM methods on pipeline ROW. The goal is to produce a reference that will be useful to practitioners in selecting the least-costly and most beneficial ROW vegetation management techniques from a longer-term perspective of sustainability.

“Enhancing the performance of urban storm water management schemes with tree selection: developing a new approach to accessing waterlogging tolerance in temperate trees”

The increasing prominence of stormwater management schemes provides excellent opportunities for the integration of trees into new urban developments; however, there is considerable uncertainty over which species will perform best in these schemes. A notable feature of landscapes designed to manage stormwater is that the substrates used are very free draining. This means that the tree species used must be tolerant to periods of both waterlogging and drought (water deficit).

This project aims to develop a new trait that can be used to develop robust recommendations on the tolerance of trees to waterlogging. This will form part of a constellation of traits that can be used to characterise the tolerance of species to a suite of key stressors in urban landscapes.

As sapflow in trees integrates the aerial and underground environments it has significant value in assessing the physiological activity of different species under contrasting environmental conditions. This study will look at the decline in sapfow under waterlogging and use this to quantitatively evaluate a range of species’ waterlogging tolerance. Further data will be collected on the species’ drought tolerance. It is anticipated that this information will transform the confidence of recommendations for stormwater management and provide a model for others in the research community to quantitatively evaluate tolerance to waterlogging. The overall goal of the project is to improve the confidence of tree selection for stormwater management schemes and sites prone to waterlogging.

 

Safe Arborist Techniques Fund Grant

Alexander Laver and James Shippen, PhD, Tree Logic (Working with Coventry University, UK)

“Optimised techniques for arboreal activities”

Recent advances in biomechanical motion analysis equipment has enabled the measurement of three-dimensional human movement within environments previously inaccessible. Previously motion analysis was performed using optical tracking equipment which, whilst accurate, was unsuitable for use outside and excluded its application to tree climbing. However motion capture equipment is now available which uses inertial tracking sensors and can operate in more realistic scenarios such as within the canopy of a tree. With this kit we are going to be able to map the movements of a tree climber as they climb, the data will then give us a body map showing the skeleton and muscle structure of the climber. We plan to record different access and climbing methods to analyse the effect on the climber body. We then plan to look at the task in the tree and work positioning options when undertaking those tasks. Having captured this information we can target a study, working with the climbers of mixed experience to see if climbers adapts their method to compensate for the stress and strains of the method or task. We hope this will guide us to recommend the best climbing methods for climbers to learn and master, to keep them fit and health and in the industry for a full and long career.

“The cost-effectiveness of integrated vegetation management”

There are 450,000 miles of transmission line operating at 35-765 kV across North America, with a total land area being managed as electric transmission rights-of-way (ROW) estimated at between 9-11 million acres. There are an additional 306,000 miles of natural gas and liquid petroleum pipeline in North America, representing an estimated 2 million areas of land. The researchers believe that less than half the total land areas in ROW is currently being managed under an IVM regime.

A project team led by John W. Goodfellow, and including SUNY College of Environmental Science and Forestry professors Chris Nowak Ph.D. and John Wagner Ph.D., recently completed a project that defined the economic business case for Integrated Vegetation Management (IVM) on electric transmission ROW. The scope of that project applied least-cost economic analysis methods that focus exclusively on the direct cost to the utility of IVM practices. That approach limited any consideration of the benefits of IVM to simply avoided cost. However, indirect costs and benefits of IVM are important considerations.

The project being proposed will supplement the least-cost project, broadening the assessment to include consideration of the many benefits of IVM, and will result in a more holistic assessment that includes both economic considerations and environmental externalities associated with IVM. This will be accomplished by applying a cost-effectiveness analysis method to empirically combine monetary costs of a management action with outcomes produced from that action that can also be quantified, but that are not easily monetized. The project will also update and broaden the focus of the original least-cost study to include application of IVM methods on pipeline ROW. The goal is to produce a reference that will be useful to practitioners in selecting the least-costly and most beneficial ROW vegetation management techniques from a longer-term perspective of sustainability.

Carolyn Mahan, Ph.D., (Penn State University) and Phillip Charlton, Ph.D., will be collaborating with Mr. Goodfellow and Dr. Nowak for this expanded study.

“Long term effects of electrical right-of-way vegetation management on floral and faunal communities”

This project will continue, replicate, and expand the research and outreach efforts on the effects of right-of-way maintenance on floral and faunal communities at State Game Lands (SGL) 33 in Centre County, Pennsylvania and Green Lane Research and Demonstration Area (GLR&D), in southeastern Pennsylvania. The research team will be collecting data to understand the response of native bees and breeding birds midway through the treatment cycle on both the SGL 33 and GLR&D sites. The research team will also evaluate floral and faunal response to right-of-way management on a third study area in central Pennsylvania. This third area will be one that is 100 feet wide and has been managed using typical integrated vegetation management techniques.  Finally, the project will add an examination of ground beetle diversity (using pitfall traps) to the existing research design at all three research locations. Ground beetles are useful as sensitive environmental indicators and can help evaluate if vegetation management treatments affect soil communities and processes. All research will be conducted in cooperation with the Center for Pollinator Research and the Frost Entomological Museum at Penn State University.

Behind the Research: Meet Dr. Kathleen W...

How did you get interested in your field of work?      

Both of my parents came from farming families in the Midwest. My dad was a landscape contractor and avid outdoorsman. So being in nature was just part of growing up in the Pacific Northwest. I attended a liberal arts college where I majored in Biology, but was interested in both social and biological systems. My first real job? I was the first  urban forester for the City of Key West. I loved the intersection of the temperate and tropical flora in the Keys. Landscape architects started calling me to specify plants for their designs. I enjoyed working with them, and thought, this is it, a professional connection between people and plants. So, I went on to pursue a master’s degree in Landscape Architecture at the University of Michigan. While there I took classes with environmental psychologists Rachel and Stephen Kaplan. I was hooked; their studies of nature and human response were fascinating. They developed the Attention Restoration Theory, the idea that that our busy lifestyles deplete our ability to concentrate and be productive, so we need to spend time outside to recharge. So, I ‘re-enlisted’ for the Ph.D. program and continued with studies about the  patterns of human response to nature. This research, a passion, combines nature, science, culture, and (sometimes) design.

Your current research focuses on nature and human health. What is your ultimate goal with this line of study?

Research confirms that humans literally need time in nature, and I’m proud to have been part of that community of science. Evidence demonstrates that everyone needs access to “nearby nature” on a regular basis. This is not about that occasional vacation trip, or getting away from the city. It’s about every person having a consistent supply of ‘metro nature’ around them all the time. Next we need to provide nature programs that encourage more healthful activities. Some people don’t recognize nature benefits or don’t know how to enter that space. Programs like “Walk with a Doc” or “Yoga in the Park” can help. Of late I’ve become interested in making the availability of nature part of city policy beyond urban forestry, to elevate the science of nature benefits to city-wide change. The need(!) for trees, parks, and gardens needs to be integrated with housing policy, transportation policy, and so on, so it becomes part of all city systems.

What trends do you see in this area of research?

The research is expanding; I think the bigger change is social change. There is now greater public awareness and recognition by public officials of nature and human health benefits. And people in environmental health have traditionally focused on clean air and water, and removing toxins. Now they’re looking at nature in cities as a salutogenic influence, a way to prevent disease and promote health. This leads to all sorts of new research questions:

  • What is the best “dose” of nature? Where, how much, how often?
  • What are the characteristics of nature (e.g., native plants vs. ornamental) that are better for human health?
  • Do people of different cultural backgrounds, age groups, etc. require different types or doses of nature?
  • Do different clinical situations (i.e., asthma vs. heart problems, etc.) call for different nature encounters?

There’s also more interest in collaboration across science disciplines. At the University of Washington, we have a cross-campus Nature & Health group that welcomes all comers. It is hosted by REI and the UW Center for Creative Conservation. We discuss research plans, and lots of topics, including equity and diversity within urban forestry, and management plans for urban forestry that include human health. 

What’s next with your research?

I’m working with Health Canada and Natural Resources Canada on a literature review of city trees and human health response, and estimate that an article will be ready to submit in about six months. The next step would be to monetize those health benefits. Then in collaboration with The Nature Conservancy and the Forest Service, I will be teaming up to develop a Health Metrics Toolkit for community-oriented projects. It will be sort of like i-Tree, but with a human health orientation. It will allow communities to measure the health outcomes of their local programs. Ages and stages . . . lately I’m elevating my interest in human health and nature research to broader situations such as community level metrics or city level policy.

Do you have any final thoughts or words of wisdom you’d like to share?

Trees and arboriculture are important. But I think we should take urban forestry to another level in many communities. Trees are part of human health solutions, but we may need to take a broader look at how we define nature in cities and who we partner with.

 

Leading Thoughts – May 2018...

By J. Eric Smith, TREE Fund President and CEO

I live in downtown Chicago and work in Naperville, Illinois, with about a 70-mile roundtrip home-to-office commute each day. I cover most of that distance on trains, but there’s about six miles each day that I do on foot. While the weather is (finally!) halfway decent this month, my walking experience is still not exactly optimal, since I’m trudging through the funky smell (somewhere between cat urine and spoiled tuna) of the dreaded Bradford, Cleveland Select, and other ornamental pear trees, typically high on the “worst trees” list for arborists and urban foresters.

They are everywhere in and around Chicago, both in planned locations (I look out from my condo over a sea of them in Grant Park, and there are lines of them at Naperville’s train station) and in unfortunate, unplanned sites; the supposedly-sterile invaders have gone feral over the years, cross-pollinating with other pear trees, their often-thorny, always-brittle spawn popping up aggressively as weeds, to the detriment of other species. I grew up in a part of the country that was devastated by kudzu, and there is an increasing awareness that Bradford and related ornamental pear crosses may be an even more disastrous and expensive-to-mitigate plague than the creeping vines that ate the Carolinas.

And yet: in the past year, new sections of the Chicago River Walk have been completed near the confluence of the North and South Forks. I watched the construction and was pleased to see many of the scientific planting principles we espouse being deployed in the preparation stages – only to be disappointed when they ended up putting in ornamental pears! The developers of these new municipal assets must be aware of the fact that they are planting “bad” trees to get a few weeks’ worth of pretty flowers each year, but somehow their life cycle arithmetic and aesthetic considerations still point to ornamental pears. And that’s just wrong.

TREE Fund can play a role in better educating urban and municipal planners, developers, landscape architects, civil engineers and other related professionals to not make such mistakes. In fact, this is the purpose of the Bob Skiera Memorial Building Bridges Fund, which will award grants for programs to educate decision-makers outside of our core arboricultural disciplines on what to do – and what not to do – with our urban and community forests.

We are within about $20,000 of the $500,000 goal to activate this fund in 2019. If you’d consider making a gift to the Skiera Fund, we’ll be better able in the years ahead to fight the blight of bad, bad trees.

Volunteer Spotlight: Peter Sortwell...

This month’s volunteer spotlight is shining on Peter Sortwell, Founder and CEO of Arborwell, and first-time Tour des Trees rider. Peter has always wanted to ride the Tour, but his busy life as an arborist, business owner, community volunteer and father left little time to pursue that goal. At his recent retirement as Chairman of the Board of TCIA, the organization surprised him with “seed” money for a Tour fundraising campaign. Peter immediately registered to ride and in the first week had turned that initial gift into ~$7,800 for tree research and education!

We are grateful for Peter’s many contributions to the tree community through the years, his enthusiasm for the Tour, and his leadership at TCIA that benefits all of us in the industry. Thank you, Peter, for your support of TREE Fund and its mission!

 

To suggest someone for the Spotlight, please contact Karen Lindell.

The Utility Arborist Research Fund: Adva...

By Randall H. Miller, Director of Research, Development an Industry Intelligence, CNUC

 

In the late 2000s, when I was on the International Society of Arboriculture (ISA) Journal of Arboriculture and Urban Forestry Editorial Board (now referred to Associate Editors), ISA sought International Organization for Standardization (ISO) accreditation for the journal. The application failed largely because too many articles did not meet ISO standards. Utility contributions were specifically identified as culprits, including some from researchers we held in high regard. The failure was an embarrassment for ISA, more so for the UAA, and awkward for me, as I had reviewed and approved some of the articles that were specifically criticized as scientifically deficient.

The message to the Editorial Board was clear: we had inadequately fulfilled our responsibility to ensure scientific rigor and had allowed publication of too many substandard articles for a periodical of the quality that the Journal of Arboriculture and Urban Forestry aspired to be. The board responded with steadfast focus on scientific methodology and statistical analysis. Rightly or wrongly, utility articles were particularly scrutinized. It became difficult for utility research to earn approval, as reviewers looked closely for flaws in methodology, analysis, and conclusions. Several utility research articles from prominent investigators were rejected, even though they resulted in solid recommendations we apply today. Consequently, utility researchers grew discouraged from submitting articles to the publication entirely. In fact, from 2010 to 2015, no utility-related research was published in the Journal of Arboriculture and Urban Forestry. That doesn’t mean utility research stopped, it just wasn’t printed in our profession’s scientific periodical.

The Utility Arborist Research Fund (UARF) holds promise to dramatically improve matters. As a past president of the UAA and former Chair of the TREE Fund Board of Trustees, I see clearly that the partnership between the two organizations is a strength of the UARF. TREE Fund is an ally of the UAA, and its board has a strong utility presence, with Will Nutter from Wright Tree Service, Dave Krause of Asplundh Tree Experts, and Tom Wolf of Davey. Progress toward and final achievement of the fund’s $1.0 million activation goal was monitored closely and celebrated at TREE Fund. The UAA and TREE Fund both have fundraising capabilities. The UAA can identify research topics, promote those of greatest benefit and recruit investigators. At the same time, TREE Fund is adept at managing endowed funds, prioritizing the highest quality projects, awarding the best among them grants, and publishing the results.

That doesn’t diminish the importance of strict adherence to scientific principles. TREE Fund’s Research Committee is committed to vetting research proposals, and will not award grants to projects they do not consider publishable. Utility investigators would benefit from collaborating with partners at full-time research institutions. After all, they are experts who understand how to design research that distinguishes significant results from those due only to chance. Approval from the TREE Fund Research Committee can assure us and the investigators that UARF projects are high-quality science, they will be published, and they will be successful.

Research has already been approved. The first UARF grants (2012 to 2014 ) supported John Goodfellow’s work to develop and prove a quantitative approach to determining optimal vegetation management (VM) spending and cycle times. The project Development of a Business Case for Scheduling Utility Vegetation Management (UVM) on a Preventive vs. Corrective Maintenance Basis was successful in constructing and validating a risk-based model that can support informed decisions on the tradeoffs between vegetation maintenance expense and tree-initiated risk to overhead distribution systems. The project report was issued in late 2015, and demonstrated that without consideration of the indirect cost impact of outages on customers, it may be difficult to establish a basis for preventive maintenance. A 2016 UARF grant to Christopher M. Halle, PhD (Sonoma State University) and Co-Investigator Claudia Luke, PhD (Sonoma State University) in cooperation with Pacific Gas and Electric (PG&E) Corporation compares the efficacy of mechanical-only versus mechanical-plus herbicide treatment in establishing low-growing native plant communities in a range of western ecosystems in the project called Integrated Vegetation Management (IVM) On Powerline Rights of Ways: Effects Of Vegetation Treatment On Plant Communities and Wildlife Diversity. The effects on local animals and pollinators will also be studied.

These projects are only the start. Beginning in 2018, TREE Fund, in consultation with the UAA, will award one to five UARF grants totaling $50,000 annually (minimum award of $10,000). There is no end to potential projects—determining optimal cycle lengths, the efficacy of separate approaches to single and three phase lines, wire-border zone investigations outside of Pennsylvania and California, whether “ground-to-sky” pruning negatively affects mass damping, how to improve public perception of utility arboriculture, etc.

The UARF has the potential to take us into a golden age of utility arboricultural research. By the UAA and TREE Fund working together with academic collaborators, we will position ourselves to dramatically improve our understanding of UVM, and better serve the companies for which we work as well as our customers, and ultimately our profession.

TREE Fund awards seventeen new grants in 2017

Funding empowers wide array of tree research and education projects across the globe

 

Naperville, IL, February 26, 2018 – TREE Fund is pleased to announce nearly $225,000 in new awards for urban tree research and education in 2017. With these grants, the 501(c)3 charity has provided over $3.4 million in funding since its inception in 2002.

Two of the 2017 awards are centered on improving worker safety in tree care, a critical focus in a perilous industry. The new Safe Arborist Techniques Fund grant line is looking at current safety standards, and the Frank E. Gamma, Sr. Arboriculture Education Fund supports Tree Care Industry Association’s Arborist Safety Training Institute, which brings high quality, local and affordable safety training to working arborists.

“The wide array of grants that TREE Fund awarded in 2017 demonstrates the extensive impact that we and our research partners can have on communities within and beyond the tree care industry,” notes TREE Fund President and CEO J. Eric Smith. “From the broad quantification of human health benefits gained from city trees to approaches for battling tree disease on a microbial level, we are seeking to empower tree care professionals at all levels, and to educate lay people and policy makers alike on the economic, health and aesthetic benefits of healthy urban canopies around the world.”  

2017 TREE Fund Hyland R. Johns Research Grant recipients:

Richard Hauer, PhD (University of Wisconsin – Stevens Point) is creating an easy-to-use tool to evaluate and track progress within urban forestry programs. Ultimately the “Sustainable urban forestry planning models and decision making dashboard” project will help urban forest planners create a story of the current state of their urban forestry program and identify areas to improve, thus leading to a sustainable urban forest program and tree population.

Kathleen Wolf, PhD (University of Washington) seeks to extract research about human health benefits specific to city trees and forests and conduct an economic valuation of such benefits. The “Urban forests for human health: a focused economic valuation” project will provide professionals in arboriculture, urban forestry, landscape design, etc. with additional data for justifying the costs of tree planning, planting and management.

 

2017 Safe Arborist Techniques Fund Grant recipient:

Brian Kane, PhD (University of Massachusetts Amherst) is collecting and analyzing safety standards from around the world in the “Arboricultural safety around the world” project. It will serve as a foundation for future studies into safe working practices in arboriculture.

 

2017 Directed Research Grant recipients:

Eric Wiseman, PhD (Virginia Tech) and Co-Investigator Sarah Gugercin (Virginia Department of Forest Resources and Environmental Conservation) is cataloging organizations involved with arboriculture/urban forestry educational grant-making programs in recent years. The “Education Review Program” project will provide a thorough analysis on such programs to guide decision-making on future TREE Fund Arboriculture Education grants.

Andrew Koeser, PhD (University of Florida – Gulf Coast REC) and Co-Investigator Rich Hauer, PhD (University of Wisconsin – Stevens Point) aims to conduct a comprehensive review of all past TREE Fund-supported research in their study “Research Review Program.” Their work will gauge direct and indirect outcomes, outputs, and impacts of the funded projects. 

 

2017 John Z. Duling Grant recipient:

Nina Bassuk, PhD (Cornell University) seeks to improve tree transplant success and ultimately provide greater tree species diversity in the nursery industry via root manipulation. In the “Enhancing Tree Transplant Success through the Manipulation of Root Hydraulic Conductance” project, Dr. Bassuk will manipulate root growth to increase the rate and efficiency of water uptake, resulting in a production practice that can improve a tree’s ability to respond to transplant shock.

 

2017 Jack Kimmel International Grant recipients:

Kimmel grants are supported by Canadian TREE Fund and its riders in the Tour des Trees outreach and fundraising event.

Rachael Antwis, PhD and Co-Investigator Stephen Parnell, PhD (both University of Salford, U.K.) are exploring natural microbial communities of trees as a way to address emerging infectious diseases such as the chalara fungus infecting ash. The “Fighting microbes with microbes to protect our native trees” study aims to identify microbial signatures of ash resistance to chalara and markers of host gene expression to identify resistant trees for cultivation and reforestation. 

Liliana Franco-Lara, PhD and Co-Investigator Helena Brochero, PhD (both Universidad Militar Nueva Granada) aim to better understand the diseases caused by phytoplasma (a type of bacteria) that are affecting urban trees in Bogotá, including the strategically important Andean oak (Q. humboldtii). The “Identification of possible insect vectors of phytoplasmas in Quercus humboldtii Bonpla in Bogotá, Colombia” project will detect the insects associated with the Andean oak and identify the species that may be transmitting the bacteria. Findings will serve to define strategies to manage and reduce the spread of phytoplasmal diseases.

 

2017 Arboriculture Education Grant recipients:

Friends of the Urban Forest (San Francisco, CA) – The “Green Teens – Vocational Skills Job Training” initiative provides practical job skills training to low-income, high school aged youth. It is an integral part of the organization’s plans to expand and preserve San Francisco’s tree canopy, while empowering at-risk youth.

TreeFolks (Del Valle, TX) – With the “Youth Tree Climbing Initiative” TreeFolks will expand its active and educational urban forestry activities for underserved youth in Austin to include tree climbing.

 

2017 Ohio Chapter ISA Education Grant recipient:

Columbus State Community College (Columbus, OH) – The “Columbus State Arboriculture Education Expansion and Tree Care Academy Project” seeks to increase awareness of the field of arboriculture and create an entry point for the college’s new Arboriculture Technician Certificate. The weeklong Youth Tree Care Academy for students age 16+ provides a hands-on introduction to arboriculture as well as the certificate program. 

 

2017 Frank E. Gamma, Sr. Arboriculture Education Fund recipient:

Tree Care Industry Association Foundation (Londonderry, NH) – This grant supports the Arborist Safety Training Institute which works to bring high quality, local and affordable safety training to working arborists. ASTI provides grants for job and safety training to minimize injury and promote overall workforce safety.
