KEYNOTE: Arbori-what?
John Parker - Arboricultural Association, Stonehouse, UK
“Very few people know or give credit to the science of tree care, or arboriculture, to give it its proper title.” These words could have been written today, but in fact this is a quote from an article by Bill Matthews which was published in the Arboricultural Association Magazine of December 1971. In this presentation, John Parker – Chief Executive Officer of the Arboricultural Association – will describe some of the key challenges facing the arboricultural sector in the UK and will explore some of the ways in which the profession is responding to those challenges. In particular, John will focus on the key challenge of a lack of recognition of arboriculture. Everyone seems to be talking about the importance of trees, but tree care professionals are rarely considered by the general public or politicians. Tree planting remains extremely popular, but tree establishment is often forgotten about. What can we do to bridge these gaps in order to ensure a healthy and sustainable arboricultural profession? John will attempt to address this question through discussing the current situation in the UK and describing what the Arboricultural Association and its members are doing to try to improve the situation.
9:15 AM – 10:00 AM
Bridging the Gaps: Insurers, Arborists, and Homeowners
Matthew Gauldin - University of Georgia, Athens, GA
Privately-owned yard trees can impose risk to personal property through whole or partial failure. To better address increasing risks related to climate change, insurance companies are continually changing their underwriting requirements and, in this process, trees have come under greater scrutiny. The processes which the insurance industry uses to assess, mitigate, and communicate tree-related risks are not well-understood by the public and are absent from urban forestry literature. Yet, preliminary evidence in the North American news media and elsewhere suggests insurance companies increasing impact on the urban tree canopy through their influence on homeowners' decisions. My research employed qualitative interviews with insurance agents and arborists in the Southeastern United States. Drawing on the risk communication literature, my research objective was to describe the factors behind tree-related determinations by insurance companies and their influence on homeowners’ choices concerning yard trees. I discovered agents act as the insurance underwriters’ mediators to build trust with their customers and overcome the obstacles that changing underwriting and organizational processes have influenced. I also found that many arborists have become disillusioned with the insurance industry but are open to building better professional relationships. This research helps to inform insurance risk communication practices to build trust with customers, agents, and arborists, and to encourage greater use of arboricultural standard practices when determining climate-smart tree-related risk determination. This research also helps to inform arborists of how-to better approach interactions with homeowners insurance companies and helps them to grow a greater understanding of insurers rationale and protocols with trees.
10:00 AM – 10:30 AM
Refreshment Break with Trade Show Exhibitors
10:30 AM– 11:15 AM
Inventory to Preservation: The Good, The Bad, The Ugly
Eric H. Hoyer - Natural Resource Planning Services, Inc., San Antonio, FL and
Jordan Upcavage - Independent Tree Service Inc., Tampa, FL
The case study includes a multi-family housing development involving a tree inventory, evaluation, and tree preservation plan. Implementing creative tree preservation strategies and discussing the overwhelming challenges of the job and how it evolved many times during the construction process.
Discussion of the current condition of the trees including successes, failures, and lessons learned from this assignment. Also, including a new assignment in the planning stages (no development yet) including relationship with the developer and the importance of getting involved on the front end of the project, with the developer valuing the importance of tree preservation (an overwhelming challenge for most arborists).
11:15 AM – 12:00 PM
Arboriculture Apprenticeships in Florida?
Erin Aaron, Tree Care Industry Association, Manchester, NH
This presentation explores the implementation and expansion of registered arborist apprenticeship programs in Florida, highlighting the benefits for both employers and job seekers. Registered Apprenticeship Programs offer a proven, structured training model that combines on-the-job training with related technical instruction, tailored to meet industry standards. By fostering partnerships between businesses, educational institutions, industry associations, and government agencies, these programs aim to address skill gaps, enhance workforce quality, and boost economic growth. Attendees will learn the process of establishing apprenticeship programs and the positive impact on productivity, employee retention, and career development in arboriculture.

Practicing Arboriculture with a Scientific Mindset
Dr. Andrew Koeser, University of Florida Gulf Coast Research and Education Center, Wimauma, FL
Through research, technology, and education, the International Society of Arboriculture (ISA) promotes the professional practice of arboriculture and fosters greater worldwide awareness of the benefits of trees. This mission is driven by research and innovation—not just lofty ideals, but essential tools for success. Practicing arboriculture with a scientific mindset will set you apart from the competition, help you avoid gimmicks and misinformation, and allow you to make a real impact on your clients and their trees.
In this talk, first delivered at the ISA Annual Conference as the L.C. Chadwick Research Award Lecture, attendees will explore five key tenets for adopting a scientific mindset, drawing from lessons learned through past research.
1:45 PM – 2:30 PM
Standards? But We are Unregulated!
John Parker - Arboricultural Association, Stonehouse, UK
Arboriculture in the UK remains an unregulated profession. In theory at least, anyone can buy themselves a chainsaw and call themselves an arborist. This situation has serious implications for health and safety, standards of tree work and for the reputation of the sector, and this presentation will explore some of the ways in which the Arboricultural Association and partner forward professionalism in a difficult environment. This includes accreditations such as the Approved Contractor and Registered Consultant Schemes, professional membership and charterships, continuous professional development and training, best practice guidance documentation, political lobbying and public engagement. There is also an important link here with the succession crisis in arboriculture – where is the next generation of tree acre professionals coming from, and how do we attract them to the sector and offer them a clear pathway of career development? Things have certainly improved in many ways over the six decades since the Arboricultural Association was founded, but there is still much to do.

Field Guide to Disease in Florida Trees
Katy Deitz, University of Florida, Gainesville, FL
This field guide is intended to assist arborists in diagnosing trees in landscapes and managed areas through the use of synoptic keys. This guide features common tree diseases and abiotic disorders encountered in Florida but may also be useful for the Southeast.
3:30 PM – 4:00 PM
Determining the Limits of Radial Root Growth: Trees and Sidewalk
Dr. Andrew Koeser, University of Florida Gulf Coast Research and Education Center, Wimauma, FL
Trees are extraordinary organisms, overcoming tremendous obstacles to push their roots through the soil while keeping their limbs reaching skyward. Though their resilience is remarkable, every tree has its limits—whether from overly compacted soil or powerful winds. But what if we could measure these limits and use that knowledge to design more resilient hardscapes? In this study, funded by the Florida Chapter ISA Grant Program, we highlight findings from a three-year investigation into the limits of radial root growth (diameter expansion). Join us to discover: How much pressure is too much for a root to overcome? And how can this knowledge help reduce tripping hazards and sidewalk lifting?
4:00 PM – 4:30 PM
Right Place for Urban Tree
Dr. Adam Dale, University of Florida, Gainesville, FL
We commonly reference the phrase, 'right plant, right place', regarding setting up urban trees for success. This may refer to USDA Hardiness Zones, soil moisture, sun exposure, overhead power lines, and other common factors that may affect long-term tree health. However, urban landscapes are nuanced and dynamic. In his session, we will discuss how characteristics of urban landscapes, like pavement, surrounding vegetation, and access to resources influence trees and the insect pests that affect tree health. Using multiple case studies, we will discuss specific ways to increase the longevity and health of trees planted and/or maintained in urban landscapes.
4:30 PM – 5:00 PM
Impact of Injection Regimes
Stephanie Adams, Texas A&M University, College Station, TX
Performing stem injections is a common practice in plant health care. This practice helps ensure the product enters the targeted tree and minimizes unnecessary non-targeted environmental impact. Unfortunately, it also requires mechanically injuring the tree. This presentation will highlight the pros and cons of long-term injection practices.

Wood You Be My Neighbor? Dead Wood Conservation in Urban Landscapes
Katy Deitz, University of Florida, Gainesville, FL
Dead wood plays an important role in ecosystems. Fungi and insects break down wood into new soil that can be used for new trees and plants. Likewise, everything from dead branches to stumps, from logs to snags or wildlife poles can be occupied by many different organisms for nutrients and habitats. This campaign aims to keep dead wood in urban landscapes to promote biodiversity and reduce habitat fragmentation.
8:40 AM – 9:00 AM
The Impact of Urban Trees on Stress Levels
Christy C. V. Suhendy, University of Florida, Gainesville, FL
This study investigated the relationship between urban trees and stress levels in Florida residents using the 3-30-300 rule framework. Data collected from Florida adults aged 45+ via an online survey that measured perceived stress using the PSS-4 scale, along with demographic information and green space engagement patterns. The findings suggest that regular, active engagement with green spaces plays a more critical role in stress reduction than mere proximity or passive exposure to urban trees. This underscores the importance of designing accessible, engaging natural environments that encourage frequent use, rather than simply increasing tree numbers or canopy coverage.
9:00 AM – 9:20 AM
Trees and Climate Change
Teagan Young, University of Florida, Gainesville, FL
This presentation explores how climate change is reshaping urban forestry practices by integrating insights from controlled greenhouse experiments and multisite field trials. First, we examine the physiological responses of six common Florida urban tree species—Acer rubrum, Lagerstroemia indica, Liquidambar styraciflua, Magnolia grandiflora, Quercus virginiana, and Ulmus alata—subjected to elevated temperature treatments (30°C, 36°C, and 40°C) over 21 days. Key measurements, including water potential, turgor pressure, chlorophyll content, visual leaf stress, and quantum yield fluorescence, revealed marked species-specific variability, with Quercus virginiana and Magnolia grandiflora showing superior heat resilience.
The presentation then connects these findings to the 2023 USDA Plant Hardiness Zones update, which reflects significant temperature shifts in Florida. Field trials conducted in Davie, Gainesville, and Quincy assessed the performance of six underutilized tree species—Araucaria heterophylla, Bulnesia arborea, Exothea paniculata, Guaiacum officinale, Krugiodendron ferreum, and Vachellia farnesiana—across different climatic zones. Results underscore that while species like Vachellia farnesiana and Araucaria heterophylla thrive in warmer settings, others struggle in colder conditions. By combining controlled experiments and real-world evaluations, this research provides actionable insights into urban forestry planning. It emphasizes the importance of selecting climate-adaptive species, implementing assisted migration strategies, and tailoring tree selection to local environmental conditions to ensure the long-term ecological health and resilience of urban green spaces.
9:20 AM – 9:40 AM
Quality of Nursery Stock in Florida
Taylor Sherer, University of Florida, Gainesville, FL
Currently, little is known about the variability of nursery stock quality between big box stores and local growers. The presentation outlines current research aimed at evaluating the quality of 15-gal. live oak in Florida by 1) quantifying the likelihood and severity of root defects, 2) determining the quality according to the Florida Grades and Standards for Nursery Plants, 3) evaluating the development of defects based on two different approaches to pruning (i.e., proactive vs. reactive), and 4) assessing the amount of pruning required to reach an acceptable grade. Furthermore, surveys will be conducted for homeowners to compare the data from the field trial to real market behaviors exhibited and green industry professionals to better understand nursery production methods. Additionally, the research seeks to determine each group’s understanding and implementation of planting and pruning BMPs for young trees.
9:40 AM – 10:00 AM
Are Trees the Answer? Rethinking Climate Resilience in Urban Communities
Lillian Dinkins, University of Florida, Gainesville, FL
This research explores the role of climate resilience initiatives in urban communities, questioning whether tree planting alone is the solution to environmental challenges. Through interviews with organizations across the Southeast, this research examines how climate resilience is defined, the extent to which communities are involved in decision-making, and the strategies used beyond tree planting to address environmental inequities. By analyzing these perspectives, this study sheds light on the power dynamics shaping urban climate initiatives and their long-term impact on marginalized communities.
