Contract Climbers: An Untapped Training Resource
This presentation discusses the numerous benefits professional contract climbers bring to companies of all size. The profession of arboriculture continues to struggle with a lack of training resulting in injuries, fatalities, and property damage. This is particularly true for small companies that are not ready to hire a qualified crew supervisor. Professional contract climbers offer a unique solution to improve crew safety and productivity. Learn how a professional contract climber can help improve knowledge, skills and safety culture and your company.

Growing and Anchoring Trees on Elevated Structures
This presentation discusses the numerous benefits of setting tree cover canopy goals. Ground-level tree planting is relatively straightforward, but more tree planting opportunities exist on rooftops and other elevated structures, which comprise a significant percentage of urban impervious surface. The functionality of these rooftop oases can be dramatically increased when complimented with large maturing trees. However, growing and anchoring trees on elevated structures present many challenges, such as ensuring wind stability, managing weight and minimizing risk from multi-story branch drop. This presentation defines, explores, discusses, and addresses these challenges and increases your knowledge of horticultural systems specialized for high-elevation urban trees.

Landscape Soil Testing
This presentation discusses specifics of soil testing, including proper management practices and components to be aware of when testing. Increasingly, the importance of soil testing before prescribing use of fertilizers is recognized, but all soil tests are not created equally; agricultural soil metrics are not appropriate for use in landscapes. Moreover, relevant soil test data can be correlated with careful site observations to learn more about what constitutes sustainable levels of organic matter and nutrient levels. Learning how to interpret soil test by ground-truthing with site conditions allows arborists and landscape managers to understand how rhizospheres are currently functioning and what, if anything, should be added.

Assessing and Managing Aging Urban Trees
While aging urban trees provide a wealth of benefits to the residents who live amongst them, they may also begin to pose more risk, and as urban centres become increasingly dense, trees, people and infrastructure often come into conflict. Balancing these competing interests while looking out for the trees can be a real challenge. Today’s arborists can choose from a wealth of methods to better manage and assess the risk of trees. The recently introduced ANSI A300 Part nine describes three levels of risk assessment. By presenting a series of case studies, Philip Van Wassenaer will focus on how advanced risk assessment methods (Level 3) are being used to better understand the likelihood of failure and to contribute useful information used in the development of conservation management strategies for aging and significant urban trees.

Bad Inheritances in Arboriculture (Español)
In this presentation, Carlos Llanos describes how the incorrect interventions applied to trees in cities and in all latitudes severely injure adult trees. In the short term, these trees are unable to replace the support and nutrition functions performed by their roots, and, as long as the tree remains exposed, fungi, insects, and a number of other pathogens can enter through the cuts. Improvisation can result in root pruning in multiple places on the tree, which can lead to the collapse of the tree with consequences we're all familiar with in some dramatic cases.
Malas herencias en arboricultura – Carlos Llanos. En esta presentación, Carlos Llanos habla de las intervenciones incorrectas, aplicadas a los árboles en las ciudades y en todas las latitudes, que dañan gravemente a los árboles adultos. A corto plazo, estos árboles no pueden reemplazar las funciones de soporte y nutrición que realizan sus raíces y, mientras el árbol permanezca abierto, hongos, insectos y otros patógenos pueden ingresar a través de los cortes. La improvisación hace que se produzcan varias podas de raíces en el mismo árbol y conduce al colapso del árbol con consecuencias que todos conocemos en algunos casos dramáticos.

ISA’s Best Management Practices for Construction Near Trees — Dr. Tom Smiley, Dr. Richard Harper, Ryan Gilpin and Nelda Matheny
With the adoption of the newly revised ANSI A300 standard for managing trees on construction sites, the International Society of Arboriculture updated the best management practices. This presentation reviews the new standard and discusses both the science and practice behind the changes. This presentation is highly recommended for arborists who deal with construction protection for trees.

Residential Trees and the Knowledge, Perceptions, and Practices of Homeowners — Kaitlyn Pike
Kaitlyn Pike presents a follow-up to a study exploring the efficacy of a comprehensive tree preservation ordinance. Pike’s study details how surveyed homeowners view trees and nature on their property and how these views may differ between types of homeowners. The results show that homeowners are largely uninformed about the home development process and its impact on the urban canopy, and that they are even removed from decisions about their own yard. The study covered in this presentation emphasizes the importance of an ordinance that requires tree preservation during construction.

Artificial Intelligence for Tree Risk Prediction — Ryan Suttle and Nasko Apostolov
Vegetation management is typically one of a utility’s largest budget items. Presently, identification of high-risk trees near utility lines is labor intensive, time consuming, and costly. In this presentation, Ryan Suttle and Nasko Apostolov share a study that describes a machine-learning approach which trains a novel convolutional neural network (CNN) to automatically classify trees, using only a single photograph and with a high degree of accuracy, into likelihood of failure categories. The CNN’s high degree of accuracy demonstrates the potential of artificial intelligence to automate risk assessment and consequently to reduce costs. Preliminary results are extremely promising for future study and improvement.

Effects of Residential Development on Growth of Mature Trees— Greg King
In this presentation, Greg King discusses research that utilizes dendrochronology (science of annual tree-ring analysis) to investigate the long-term influence of residential development on tree growth indices. It is an opportunity to compare trees in adjacent greenspaces that were not impacted by development. The results will be informative by providing a decades-long perspective on the impacts of development on tree growth.
