This presentation combines two important urban trees—ash and London planetree—and examines their history in urban forest management. Through two case studies, Alexander Martin and Lara Roman examine how sociopolitical and biophysical drivers have shaped the composition of our urban forests.

Many people may view greenspaces simply as an outlet for recreation and don’t consider what they can offer to improve citizens’ quality of life. Greenspaces help cities to reach the minimal thresholds for human well-being and are needed in cities. In this presentation, Francesco Ferrini discusses the benefits of urban greenspaces, plant selection for greenspaces, and various approaches to greenspaces within urban forestry. Watch the presentation here before taking this CEU quiz.

Sheet mulching is a technique espoused in permaculture to suppress weeds and enhance soil health. However, there are no science-based citations to support the practice or the claims of its success. In this presentation, Dr. Chalker-Scott takes a closer look at the facts and myths around sheet mulching as well as other mulching techniques, and offers insight on the best mulching solutions for soil and tree health.

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. In this presentation, James Komen discusses how to correct for these situations by changing the way transactions are recorded. Examples are framed within the context of a typical tree service company.

Arborists often manage the likelihood of tree failure—whether while assessing tree risk or when working in a tree to reduce risk. In this presentation, Brian Kane covers key engineering and physics concepts that can help arborists better understand the likelihood of failure when assessing risk, how to mitigate risk, and how to work safely.

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.

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. The presentation accompanying this quiz will illustrate 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.

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.

Trees in coastal and island ecosystems in many parts of the world face risk from tropical cyclones, also known as typhoons or hurricanes. 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 associated 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.

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 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 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.

The terms girdling and ring-barking tend to be used synonymously in arboriculture, but in the presentation accompanying this CEU quiz, 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.
