Podcast - Measuring a Tree’s Pulse and its Relationship to Tree Health—Charles Cannon
This presentation will introduce the basic concepts of sap flow, the factors that influence it, how it is measured and then dig into our collaborative research programs in long-term monitoring and experimental trials, ending with prospective uses of the data and technology. We feel the time is ripe for the application of these kinds of tools and that they will be highly useful and informative, particularly as we accumulate replicated continuous data for many species.

Podcast - Minimizing Hazards Arising from Lignotuberous and Epicormic Shoots—Greg Moore
Wire baskets helped to industrialize the transplanting process for field-grown nursery stock. However, their use is not without controversy. Many nursery growers and others worry that removal of this packaging material at planting may disrupt an already compromised root system and reduce transplant success. In contrast, many arborists and urban foresters fear this packaging may serve as both a short-term barrier to root regrowth and a long-term source of root restriction. While opinions abound, actual research on this topic is relatively scarce. Is wire basket removal a death sentence for trees already compromised by root loss and water stress? Do wire baskets left intact lead to the slow death of trees? This presentation draws on past and recent research findings in an effort to offer an impartial view on one of arboriculture’s more controversial issues regarding cultural practice. Impact on transplanting survival, growth, and stability are discussed.

Video - Expanded Crews and Views—Jessika Mitchell
This session aims to answer questions about worker recruitment and retention through a new lens. Together we will explore the importance of looking beyond traditional hiring pools and building more gender inclusive work environment. Research demonstrates that utilizing the unique qualities women contribute to the workplace culture can ultimately strengthen our teams and increase profit margins. However, we must acknowledge that work within the tree care industry presents a unique set of challenges for women and their employers. This talk will address these challenges, explore potential solutions and provide communication tools that can be used by all members of our community to help make our industry a more inclusive and equitable environment.

Podcast - Effects of Restoration Pruning Treatment on Damaged Trees - Jake Miesbauer
When trees are damaged during storms, they typically respond through the production of sprouting branches. Referred to as epicormic sprouts, these branches are a critical component in replacing the tree crown and photosynthetic capacity. Unfortunately, there is little empirical data to guide industry best management practices with respect to crown restoration pruning. In this presentation, Jake Miesbauer discusses results from a long-term study on the growth response of damaged trees to different pruning treatments and how these results can help guide practitioners to improve their methods for restoration of storm damaged trees.

Video - The Disease Triangle, The Health Triangle - Kent Honl
In this presentation, Kent Honl discusses one of the most useful concepts in Integrated Pest Management: the Disease Triangle. On the surface, this idea seems too simple to be of any practical use. But if we look at it in greater depth through some examples, we can see how the Disease Triangle can inform everything we do in our practice as tree care professionals. The payoff can be increased effectiveness in your practices, as well as a renewed relationship with your clients as allies, rather than adversaries, in helping trees. We can also look at this concept from another angle: the Health Triangle, in which we apply what we have learned to foster resilience in our trees and landscapes.

Video - Did We Keep That Heritage Tree Too Long? - Mike Garvey
On a calm June evening in 2017, a 22-inch diameter limb suddenly fell upon a person in a municipal park, causing severe harm. The limb was part of a locally significant, 90-foot tall, 125-year-old plains cottonwood that was climbed by school kids as part of Arbor Day celebrations only weeks before the limb failed. The tree was pruned 5 years before the incident, but could this failure have been predicted and avoided? Are arborist certifications, qualifications, and routine visual inspections enough to defend our actions against charges of breach of duty? In this presentation, Mike Garvey discusses these questions.

Video - What is Tree Vitality and how to rate it - Johan Östberg
Many tree managers conduct tree inventories to monitor urban trees, and one of the most important parameters they collect is information on the tree’s vitality, sometimes called condition. But what is tree vitality, how can this be rated and how do different user groups rate tree vitality? This presenter conducted a Delphi study to compare two different user groups: arborists (consulting, climbing and municipal) and biologists (consulting and from government agencies). The study revealed differences between how the two groups rated trees with lower vitality and the factors used to rate tree vitality.

Podcast - Native or Exotic? A Never Ending Debate in the Urban Landscape - Francesco Ferrini
When planning new green spaces it is necessary to remember that the urban environment is very different from the natural environment where species have evolved, and that, sometimes, exotic species might perform better than native species. We should answer some questions when we have to choose the species to be planted: • Which trees should be planted in order to maximize carbon sequestration and pollutants removal? • Which species native and/or exotic can better face the temperature increase foreseen for the next decades? • Can the drought tolerance of certain species be increased through better management techniques? • How will the interaction between the different species change in the future?

Video - Growing Trees in Stormwater Basins in Dry Summer Climates - Igor Lacan
Results of a five-year study of tree growth and soil moisture in GSI facilities in California and Oregon indicate adequate tree condition and growth, acceptable soil chemistry, and a complete absence of extended winter waterlogging. In contrast, summer soil moisture in GSI facilities was very low, and potentially constrained tree performance. This presentation discusses the implications for tree species selection and for irrigation management. The presenter also reviews the characteristics of artificial soils (substrates) used in GSI facilities, focusing on practical information to help arborists communicate with GSI facility planners and managers. The presentation concludes with a simple protocol for monitoring trees in GSI facilities that is readily usable in the field.
