Did you miss our 2022 Virtual Conference? Here’s your chance to “rewind” and take advantage of some of these great sessions from the comfort of your home or office. ISA is excited to bring its members, credential holders and the community its new ISA Conference Rewind series.
Developed by ISA, the ISA Conference Rewind series will feature a new video each month over the next several months. The featured videos will consist of the most popular presentations from our 2022 Virtual Conference.
"The Conference Rewind series was so well received in 2021 that we decided to bring it back again for a second year. We look forward to making some of our most popular ISA 2022 Virtual Conference sessions available to a wider audience through Conference Rewind." said Jamie Vidich, director of educational products and services for ISA
This series of videos was developed to provide new educational content from the industry’s top researchers, educators, and practitioners.

Modern Urban Forestry for Modern Connected Cities: Technology Opportunities - Dan Staley
In the presentation accompanying this quiz, Dan Staley details processes, methods, and tips available today to improve efficiencies and outcomes for practitioners using technology across the arboriculture professions, as well as outlines future developments. Technologies and tools available today for arborists can be operated on smartphones, on laptops, and in the cloud, and key emerging technologies to monitor plant health are ready for market. Staley discusses these new technologies and their applications for arborists.

Applied Tree Statics: Lessons Learned from Static Load Tests for Visual Tree Inspection - Andreas Detter
Pulling tests are used to assess the strength of the anchorage as well as the load-bearing capacity of the trunk. Combined with a systematic analysis of wind forces acting on the crown, the pulling test method allows an assessment of the stability and fracture safety of the trees in storm events. The procedure has already been applied to thousands of trees worldwide. The results of numerous pulling tests may be used to improve the quality of visual inspection through a better understanding of the biomechanical background and the actual performance and strength of trees. In the presentation accompanying this quiz, Andreas Detter illustrates what arborists who do not apply the pulling tests method themselves may learn for their own practice from the large number of tests carried out by consultants and researchers in the past decades.

Beyond Butterflies: IVM in Real Life and the Road to Adaptive Management - Kieran Hunt
Most roadside and utility vegetation managers are aware of the importance of managing plants for threatened and endangered species, but any individual species (no matter how charismatic) is only a very small piece of the puzzle in a healthy ecosystem. More importantly, healthy and functional ecosystems are resilient, diverse, and more likely to support and benefit local flora and fauna. Integrated vegetation management (IVM) is the best tool for establishing and supporting communities of native vegetation that are compatible with land use. In the presentation accompanying this CEU quiz, Kieran Hunt will discuss managing land through IVM for healthy, productive ecosystems, with a focus on internal and external hurdles during conversion to IVM as well as program maturity, how it relates to project- versus program-based management, and what adaptive management looks like on the right-of-way.

Factors Affecting Urban Tree Wind Resistance to Tropical Cyclones - Dr. Allyson Salisbury
Trees in coastal and island ecosystems in many parts of the world face risk from tropical cyclones, also known as typhoons or hurricanes. Dr. Allyson Salisbury and her team conducted a systematic multi-language literature review of research on factors that influence tree damage by tropical cyclones in urban environments and compared our findings to research conducted in nonurban settings. During screening, they kept papers that collected ground-based observations of tree damage within one year of a tropical cyclone and analyzed at least one factor that could affect the susceptibility of trees to tropical cyclone wind damage (e.g., height). In the accompanying presentation, the team shares their observations of the most commonly studied types of damage and predictors of damage as well as factors in need of additional research. They also highlight common patterns observed among the studies, topics where there is disagreement in the literature, and ways our results can inform urban forest management plans for hurricane-prone communities.

Removing Turf with Minimal Impact to Existing Trees - Dennis Swartzell
In the presentation accompanying this CEU Quiz, Dennis Swartzell brings to light the extreme drought of the southwest USA and recent mandates to remove turf grass in nonresidential spaces. Unfortunately, trees located in these turf areas are subject to severe stress when the landscape conversion is conducted inappropriately. The presenter will highlight the best management practices for selection, retention, protection, and preservation of existing trees within an arid environment.

Veteran Tree Management and Protection: The Great Mulberry in Cervia - Fabio Ascarini
Veteran trees have great ecological value but above all are a cultural phenomenon. Veteran trees’ management cannot be limited to the arboricultural aspects; it must extend to the anthropological and social reasons that justify their existence. The Emilia-Romagna region has defined laws for veteran trees’ protection, management, and enhancement. The Great Mulberry (Morus alba L.) of Cervia is an emblematic case of management of a veteran tree in full compliance with the law’s principles, and it is discussed by Fabio Ascarini in the presentation accompanying this CEU. More than ten years ago, after the tree experienced severe structural failures, the Municipality of Cervia decided to implement a program for the tree’s recovery, including rooting site protection, root activity promotion, implementation of a support and cabling system, and a long-term pruning plan. The mulberry tree, which can now be said to have been brought back to a condition of ordinary management, has become an emblematic case study, so much so that it has been included in training programs.

Ring-Barking and Girdling: How Much Vascular Connection Do You Need? - Greg Moore
The terms girdling and ring-barking tend to be used synonymously in arboriculture, but the accompanying presentation by Dr. Greg Moore argues that these are two distinctly different processes, both in the actions taken by arborists and in the effects these processes have on trees. This presentation discusses research surrounding girdling and ring-barking, including tree responses, consequences of damage, and restorative measures. In discussing the two types of cuts, Dr. Moore shares how trees can often survive various levels of damage from either type of cut.

Root Defects of Container-Grown Trees: Should You Remediate Before Planting? - Riley Rouse
Riley Rouse discusses modification methods for addressing root defects of container-grown trees. Growing trees in standard smooth-sided containers can lead to malformed root systems, especially circling roots. A great number of techniques are often suggested by industry professionals to remediate root defects prior to planting. In the discussed trial, three shade tree species commonly listed as “difficult to transplant” when lifted as bare-root stock (Carpinus caroliniana, Ostrya virginiana, and Liriodendron tulipifera) and one species that is “easy to transplant” bareroot (Platanus × acerifolia) were subjected to four root modification treatments: deep slicing, shaving, bare-rooting, and control. A subset of bare-root and control trees were subjected to compensatory pruning to investigate the potential to mitigate negative crown impacts following root treatments at planting. Bare-rooting reduced survival of the species that are commonly regarded as difficult to transplant as bareroot stock. Measurements of plant water relations suggest that mortality was related to increased moisture stress associated with root and substrate removal.
