Advanced Tree Appraisal: Anchoring, Reconciliation, and Alternative Methods by James Komen

Sunday October 1, 2023 Tree Academy 1pm – 5pm 3.5 CEUs A, M, Bm

Most appraisal training is focused on a very narrow slice of the world of tree appraisal: the Trunk Formula Technique. This course explores other methods that can be used by tree appraisers. The course begins with an explanation of the concept of anchoring and how to evaluate the reliability, accuracy, and precision of data points. It then gives an overview of all three approaches to appraisal: cost, market, and income. It dives in and explores methods of appraising partial loss, diminution of market value, percentage contribution, and net present value. Next, participants have an opportunity to reconcile the many possible methods as they are applied to a given assignment. The last third of the class is a series of case studies that give participants the opportunity to practice applying the methods discussed in class and to then choose and defend their own final appraisal conclusion.

Raising the bar through GRIT (Greening Research in Tacoma) – connecting trees and community health by Ailene Ettinger, Lowell Wyse and Ryan Hebert.

Tuesday 10:20am – 11:20 am Fundamentals 1 CEU A,U,M,Bm

Previous studies tell us that neighborhoods with more pavement & fewer trees have hotter, dirtier air, but there is insufficient on-the-ground data capturing what happens in low-tree cover neighborhoods as green infrastructure is added & how people living there experience these changes. GRIT is a collaborative research project of The Nature Conservancy, Tacoma Tree Foundation, the Environment & Well-Being Lab at University of Washington & Tacoma’s Urban Forestry Program. GRIT’s focal Tacoma Mall Neighborhood is an “urban growth center,” meaning large-scale development in encouraged, to house more people in the future. Today the neighborhood is characterized by large amounts of pavement & low tree canopy, but greening efforts are underway, including planting of hundreds of street trees. GRIT builds on this by incorporating scientific research, including monitoring temperature before, during & after green infrastructure installation; asking residents about their experiences with the tree plantings & vision for the community; & building community science. Our presentation will include short talks from researchers, a city urban forester & leader of a community organization taking an integrated social-ecological approach in Tacoma, Washington, followed by a facilitated discussion among presenters & attendees on challenges & opportunities for community engagement in urban forestry research & implementation. Learning objectives: Attendees will learn from Tacoma’s experience with greening efforts (including research & community engagement); & identify opportunities for enhanced research & engagement in the landscapes in which they work.

Environmental Governance and Urban Forest Management in Indigenous Communities by Alexander Martin

Tuesday 10:20am – 11:20 am Advanced 1 CEU A,U,M,Bm

The benefits of forest ecosystems in the wildland-urban interface have largely underpinned the foci of Canada's grants for forestry and urban forestry. Naturally, many communities have expressed interest in fostering and managing forests on reserves to the benefit of the community and, through climate change mitigation strategies, Canadians at large. Through their work with Indigenous communities over the past decade, the presenters discuss opportunities, resource limitations, and environmental constraints to actionable development of urban and community forest management on Indigenous communities, focused largely on the Canadian Prairies. The presentation begins by detailing the history of environmental governance and colonialism in Canada, explaining how treaties and Canadian acts of

Parliament have created irrefutable and purposeful patterns in the creation of systemic barriers. Related to environmental justice, this presentation describes the issues related to poor soils, prohibition of controlled burns to decrease fuels, and shifts in the land tenure systems that have limited the successful implementation of urban forest management strategies. Recently, grants to fund tree planting have been established, some of which address these issues of environmental justice. Building upon the underlying environmental governance constraints, the presenters examine the opportunities for urban forest management and the creation of resilient tree planting campaigns within Indigenous communities, based both upon work with community leaders, students, and with external partners. The presentation examines successes with species selection, the blended method of conventional silvicultural practices and urban tree planting, community engagement, and long-term partnerships between communities and non-governmental organizations. Looking towards the future, the presenters discuss the potential for changes in funding approaches and ways that organizations can help support small communities’ establishment of a healthy, resilient urban forest.

Soil Oxygen: The real limiting factor for urban forest by Wei Zhang

Tuesday 11:30am – 12:30 pm Advanced 1 CEU A,T,U,M,Bs

It is needless to say the importance of the urban forestry to the community. As we plant trees in the harsh growing environment of urban areas, there are a number of questions we believe we understand them, but we may not know the real answer to them. Why most trees do not have deep roots? Why compacted soils are bad? Why is the space under sidewalks so inviting to trees roots? Overwatering creates an anaerobic condition that is bad for roots. How long does it take for the process to start? When your trees are overwatered, you typically have two options: drain the water away to save the trees with water being wasted OR save the water with the trees being wasted. Is there a third option like save both the water and the trees? The answer is yes. Why we are required to water our plants with frequent, but little water each time? Why can't we supply them 1 year worth of water a time? What makes Plant Available Water different from the precipitation/irrigation water? Why volcano mulching is bad for your trees while foot-deep leaf litter in natural forests is good for the trees? What is the one thing in common for all of these questions? Soil Oxygen. It is the real limiting factor! We will use live demonstrations to show what differences soil oxygen can make in all the above situations.

Confronting the Green Menace: Planning for Emerald Ash Borer in the Pacific Northwest by Evan Elderbrock

Tuesday 12:30pm – 1:30 pm 1 CEU A,T,U,M,L,Bs

Emerald Ash Borer (EAB) is an invasive beetle that poses a significant threat to ash tree species across North America. This presentation aims to provide a comprehensive overview of 1) EAB biology, phenology, and history in the United States, 2) Oregon's response to the recent EAB detection, 3) urban planning strategies for managing EAB, and 4) the complexities of managing native Oregon ash (Fraxinus latifolia) in natural areas. The presentation begins with an introduction to EAB, covering the EAB life cycle, as well as a historical account of its spread across the United States since its discovery in Michigan in 2002. Next, the presentation shifts to Oregon's response to the EAB detection, detailing the preparation undertaken prior to its arrival, the structure of the statewide EAB Task Force headed by Oregon Department of Agriculture (ODA), and the efforts that have been undertaken by each of the EAB Task Force’s subcommittees over the past year since EAB was discovered in Oregon.

A critical focus of the presentation will be on urban planning strategies for managing EAB in cities. Attendees will gain insights into field operations, staff training, tree inventory, EAB surveying and monitoring techniques, and management options like removal, replacement, and treatment. Considerations of wood waste and utilization, tree ordinances, financial planning, and community outreach will also be covered. Finally, the presentation will delve into the challenges of managing EAB in natural areas, specifically addressing Oregon's ash-dominated ecosystems, such as ash forested wetlands and low-elevation riparian zones. Land managers will be provided with essential considerations to preserve the native ash populations while effectively managing the EAB threat. Overall, this presentation aims to equip attendees with a comprehensive understanding of EAB biology, Oregon's response to the recent detection, urban planning strategies for EAB management, and thoughtful approaches to safeguarding Oregon ash in natural areas. By fostering a collaborative and proactive approach, the Pacific Northwest can effectively manage the impacts of EAB, turning a potential crisis into an opportunity to improve resilience of urban and natural forests for future generations.

Managerial Accounting for Tree Businesses by James Komen

Tuesday 1:30pm – 2:30 pm Advanced 1 CEU A,M,Bm

A Profit & Loss sheet is the basic yardstick for a business. It’s meant to answer the question, “How are we doing?” But in many ways, the picture presented can become distorted unintentionally and give managers a false impression of a company’s health. This presentation discusses a few of these ways and how to correct for them by changing the way transactions are recorded.

The first half of the presentation introduces the concepts of accounting journal entries and basic accounting terminology. The critical distinctions between each major account type are demonstrated through examples. Common transactions in each of the major account types are shown with debits and credits.

The next section discusses the difference between cash and accrual accounting systems, demonstrating through examples some of the shortcomings of the commonly used cash-based accounting system. Examples include worker’s compensation insurance premium estimation and measuring profit on jobs with irregular payment schedules. Common mistakes are also addressed. Ultimately, the goal of the presentation is to leave the audience with one important takeaway: the way the accounting system models income and costs can have a dramatic effect on how management decisions are made.

Using beneficial microorganisms to improve urban tree establishment by Matthew Krause

Tuesday 2:40pm – 3:40 pm Intermediate 1 CEU A,T,M,Bs

Successful tree establishment is critical for long-term urban tree health and begins in the nursery. With a continuously changing climate and increasing urbanization, newly planted urban trees face intense abiotic and biotic stresses that, combined with budget-restricted maintenance, limit the success of tree plantings and ultimately make it challenging to meet aggressive canopy enhancement targets. Poor urban soils are one of many factors that frequently contribute decline in newly planted trees. To improve urban soil health, it is important to consider the relationships between plants and soil microorganisms. These can include mycorrhizal fungi, plant-growth promoting microorganisms, plant pathogens, and other microbes growing on plants and soil organic matter. Some are beneficial to plants by providing one or more positive effects including improving soil physical properties, boosting water absorption capacity, acquiring nutrients, stimulating root or foliar growth, suppressing diseases and pests, and enhancing resistance to stresses. Specific beneficial microbes may be introduced into soils and growing media to fortify urban soils, but it’s important to understand how, where, and when to use them effectively. Together, we will explore the types of beneficial soil microbes and how they can be used to improve tree propagation and establishment in urban settings as well as support young and mature tree health. In addition, we will discuss how to navigate the myriad of beneficial microbe products in the market and general best-use practices for propagating and establishing stronger, more resilient young.

Signs and Symptoms of Insect Damage to Trees by Thomas Whitney

Tuesday 2:40pm – 3:40 pm Advanced 1 CEU A,T,M,Bs

“Treatment without diagnosis is malpractice.” This ethos not only applies to the field of medicine but also to plant health care. Without confidently identifying the disorder, how can we effectively and ethically enact management? Let’s raise the bar of plant healthcare and polish our diagnostic skillset with a focus on insect pests. A major challenge in pest management is diagnosing insect damage to trees without the insects readily visible. Oftentimes we are left only with circumstantial evidence that we must piece together. After a summary of the diagnostic process, this presentation will cover how to identify the signs (physical evidence left behind), symptoms (responses of the tree), and severity of the three main groups of insect pests: defoliators, sap-feeders, and woodborers. With numerous photo and video examples, we will explore almost every type of insect damage an arborist may encounter in the urban forest.

Climate Adaptation for Forested Natural Areas by Michael Yadrick

Tuesday 3:50pm – 4:50 pm Fundamental 1 CEU A,T,U,M, Bs

Foresight has always been a key element of care for urban forests despite the disruption we are experiencing to a stable climate. If tended carefully, the seedlings we plant today may be living in a climate very different to the one we are experiencing now. Forested natural areas will be impacted by underlying warming, urban heat islands, extending drought, variation in precipitation, extreme events like atmospheric rivers and landslides. These changes may outpace individual trees and species’ ability to adapt, causing increased exposure to insects, disease, and wildfire. This discussion will address strategies for reforestation and restoration planting in the real world.

The framework will consider principles underpinning ecological restoration, including but not limited to stakeholder engagement and utilization of varied types of knowledge. As a group we can rethink our choices given climate change projections, vulnerabilities, and adaptations for PNW urban forests. We will discuss strategies for reforestation and restoration planting. There are technologies and tools also to explore and share. Specifically, we will unpack examples of tree species selection, inequity of climate impacts on frontline communities, climate refugia, ecological thinning, expanded seed sourcing, establishment challenges and planning for emergencies.

Urban Forestry Technology for Tomorrow -Cities: Modern analysis opportunities for resilient societies by Dan Staley

Tuesday 3:50pm – 4:50 pm Intermediate 1 CEU A,T,U,M,L,Bs

Aerial remote sensing technology is changing the way we perceive, measure, and monitor earth’s ecosystems, including urban forests. Detection systems such as new satellites, aircraft, and drones able to resolve objects centimeters across are imaging the urban forest in ways that have never been more accessible. Modern analysis techniques leverage remote sensing data in ways that weren’t imagined a decade ago, and promise to benefit the next generation of urban residents by making urban forestry data available to anyone’s fingertips via digital platforms in the cloud. These platforms exist today using specialized computer language, but soon platforms accessible to anyone promise to make analysis of urban forest data immediate and impactful. This presentation is aimed at Consulting Arborists and urban foresters interested in leveraging technology to analyze data to help urban forests adapt to current and future changes. Remote sensing technology can help green infrastructure professionals better monitor and manage urban forests against threats such as worsening urban heat waves, increasing severe weather, effects of climate change, movement of exotic pests such as Emerald Ash Borer, and long-term impacts of drought. Aerial imaging technology can also monitor construction progress, track permit compliance, measure impervious surface expansion and impacts, calculate canopy cover, collect tree inventory health data, and much more. Modern computer analysis using networks and Artificial Intelligence can leverage a wealth of data to help make urban forests more resilient and accessible to residents and visitors. Attendees will understand the capabilities of each detection system, their strengths and weaknesses, their costs, and how to access, analyze, and utilize their data. Attendees will also understand current and near-future analysis capabilities to access current and near-future data platforms. Attendees will also understand what education and staffing resource changes may be needed to prepare for this new technology environment, including changes in software and hardware systems; skills to collect, access and analyze remote sensing data; new career paths that may arise from these new technologies; how to communicate with people to get the best analyses; and what possible changes in the field may occur as a result of these new technologies.

The Importance of Development Standards for Tree Planting by Jim Barborinas and Phil Bennett

Tuesday 3:50pm – 4:50 pm Advanced 1 CEU A,T,U,M,Bs

With the advent of mass development since WWII, large-scale clearing and grading has had profound consequences for tree planting sites. Without good landscape standards, site issues such as compacted soils and lack of drainage cause tree health issues, stunted growth, and early mortality – preventing trees from growing to maturity and providing maximum benefits. This presentation explores lessons learned during the development of Snoqualmie Ridge, and installation of 7,000 street and park trees from the perspective of a consulting arborist working together with a city forester.

Bio: Phil Bennett is the Urban Forestry & Stormwater Superintendent at the City of Snoqualmie, where he manages both grey and green infrastructure. Phil started his career as a “Branch Manager” for Down to Earth Tree Care in Duvall, WA in 2007.

What's So Curious About This Tree Is... by Casey Clapp

Wednesday 9:00am – 10:00 am Advanced 1 CEU A,T,U,M,L,Bs

Trees are fascinating organisms. For many of us, our fascination and love of trees is what got us into this field to begin with. However, we can often lose sight of that initial passion and enjoyment in lieu of focusing on the next job, the technical aspects of this or that, or how to keep up with everything. This presentation aims to take a step back from all that and allow you to reconnect with the tree as an organism to be amazed by. I will take you on a journey across the world to hear about the fascinating things that trees do and the events they have been a part of. The goal of this presentation is to reconnect you with trees and give a dose of passion and curiosity and intrigue that everyone can use to remember why it is we do what we do. I will pull from stories covered in my podcast Completely Arbortrary and present stories on the interesting science of trees aside from their general biology and ecology and include cultural stories as well because, 90% of the time, they are all connected anyway.

Advances in our understanding of the dynamic forces applied to a tree during removal operations: results from empirically collected data, and techniques to mitigate risk of failure by Ryan Senechal and Matt Follett

Wednesday 9:00am – 10:00 am Advanced 1 CEU A,T,U,M,L,Bp

This exciting research presentation will outline results from recent rigging experiments focused on exploring concepts in both physics and tree biomechanics and how we can incorporate these to improve on climber safety. This presentation includes previously presented work (TCIA Atlanta, ISA Malmo, ISAO London), as well as exciting new results from a recent collaborative project – the partners include University of Quebec at Montreal, University of British Columbia, and the City of North Vancouver. In this new study we focused on a topic with significant gaps in both literature and anecdotal evidence; the effect of notch angle on applied bending moment to a standing stem. This is particularly pertinent in the context of large single stem removals - as found in the Pacific Northwest - where sections are felled from the tree at height, often placing large bending moments on the tree below. During February of 2023, we systematically removed a sample of dying hemlock within the boundary of the City of North Vancouver. By measuring a suite of variables and collecting strain and motion data within the trees, we are assembling a clearer picture of the effects of specific removal scenarios. We hope to bring a fresh perspective to some of the key concepts of negative rigging scenarios, while presenting real-world empirically supported data on the loads and forces applied to the tree in removal situations. Specifically addressing how we as climbing arborists can help to efficiently and effectively mitigate those forces while still maintaining high productivity in the workplace.

Bio: With over 25 years’ experience as a practicing arborist, and currently pursuing a PhD in tree biomechanics, Matt Follett has a strong interest in the technical aspects of preserving large trees in the urban setting .

Ryan's industry safety and standards contributions include serving an industry stakeholder committee developing new arborist regulations in BC, in maintaining credentials as a member of the ISA's Test Committee, and by consulting on arborist safety for commercial and municipal tree care organizations. His research focus at University of British Columbia relates to workplace culture, worker turnover, and diminishing recruiting outcomes.

Western redcedar dieback in the urban environment by Joseph Hulbert

Wednesday 10:10am – 11:10 am Advanced 1 CEU A,T,M,Bs

Western redcedar is arguably one of the most socioeconomically important trees in the northwest. It has provided many gifts to indigenous peoples since time immemorial and was an essential resource in the northwest's heritage as the timber capitol of the world. While it is still an important part of our urban, managed and natural forests, recent increases in dieback have challenged resource managers to question its availability for future generations and its suitability for urban plantings. Western redcedar may be one of the first native trees to 'feel the heat' of climate change and deciding to plant other species or hold onto our cherished natives is certainly becoming an internal ethical dilemma. More research to explore the genetic variability within redcedar and provide guidance on the right place for redcedar in the urban environment is needed. This presentation will provide updates from analyses of the community science data provided in the Western Redcedar Dieback Map project on iNaturalist. It will share updates from the Open Redcedar Adaptation Network, which is comparing the growth of redcedar trees grown from seed collected in Oregon and Washington at three urban plantings. The presentation will also share preliminary findings about possible role of root disease as a factor in the within site variability of the dieback. Overall, participants will learn current state-of-the-science knowledge around the dieback of western redcedar, ongoing research projects, and upcoming opportunities to collaborate.

Successful Tree Planting Projects Require More Than Just Planting! By Gordon Mann and Wei Zhang

Wednesday 9:00am – 10:00 am Advanced 1 CEU A,T,M,Bs

Among the common factors affecting the survival of newly planted trees, under-watering and over-watering are the top two. Providing water to a newly planted tree for the first 2-5 years is critical for its survival and thrival. We all have seen and probably participated in one of the tree planting projects "Million Trees XYZ City" in the spring on exactly two days: Earth Day or Arbor Day. It is a great photo opportunity for politicians, but how about following up with watering in the hot summer days and/or during droughts! Trees die and spring will bring up a new round of tree planting projects. Is there anything we can do to give trees a better chance to survive? By examining the situation and looking at the root of the problem, the real limitation is in the Plant Available Water (PAW). No matter how much one irrigates the soil or how much rainwater falls on to it, any water above the Field Capacity (FC) is wasted. We will review some technologies for stabilizing soil moisture, including methods that significantly boost the PAW without drowning the plant roots. We also review methods and technologies that make the best usage of natural precipitation (stormwater) and the water that is otherwise wasted. Case studies across North America will be used to illustrate how these methods can significantly increase the survival rate of newly transplanted trees.

The Problem is the Solution Creating Assets and Potential from Liabilities and Need by Tyler Roth

Wednesday 11:20am – 12:20 pm Advanced 1 CEU A,T,U,M,Bs

The Oregon Department of Forestry's Urban and Community Forestry program has been invested in researching and creating models for urban wood utilization. Emerald Ash Borer (not a main focus of this presentation) is expected to cause mass mortality of ash (Fraxinus) species in Oregon and the PNW as it advances and spreads. With the ever-presenting effects of climate change, how can we utilize this urban wood from waste to carbon sequestration and social economic potential. This presentation will discuss the theory about future designs of how urban wood loss can be used in collaboration with houseless, refugee, troubled youth, disabled, and other communities for economic and social models. Urban wood utilization, specifically milling, is an industry of its own. We would like to discuss the potential application of permaculture theory to designing all-encompassing urban wood utilization properties. This presentation will also cover how this permaculture theory can be applied to humans to assist populations in a variety of needs for employment, education and career opportunities.”

Puppets transfer Tree Care Technology by Guy Meuillier and Karen Cantor

Wednesday 12:30pm – 1:30 pm Closing/Lunch 1 CEU A, T, U, M, Bs

People want healthy trees, but all too often feel overwhelmed about caring for them. Puppetry cuts through information overload with simplified, endearing messages. When the heart is opened, the mind follows, and tree care lessons are effortlessly absorbed. PuppetTREE’s short shows feature arborist, Dr. Treedom, caring for Trevor Tree. When Basil Kutz wants to use his chain saw to resolve the issue-du-jour, Dr. Treedom sends him information to consider. Basil comes back transformed: a newly educated man wanting to keep Trevor healthy and happy. A melange of characters - mermaids and trolls, birds and insects, people and animals - weave a wide range of tree tales. Each episode delivers a unique message: “Trevor Tree & the Carpenter Worm” (managing insects & beneficial associations), “Green Credentials,” “Girdling Roots” (mulch benefits & placement, root collar examination, girdling root removal), “Scientific Names” (taxonomic challenges), “Regenerating Trees after Storms” (assessing damage, pruning, dealing with uprooting), and “Challenge Courses“(support systems & wound management). PuppetTREE transfers technology by entertaining and educating with art and humor. A comment from 2022: “I attend many tree conferences where I hear the same information, presented the same way. Recently, I was treated to PuppetTREE. I enjoyed the sense of play, lightheartedness, imagination and the ‘boldness to try’ that enriched our experience. When the puppets introduced novel tree care approaches, my resistance vanished." Small groups of energized and engaged citizens help trees adapt to the insults of our civilization, creating a resilient urban forest.
