The purpose of this study is to examine the number, health, and species of trees in the gentrifying neighbourhood of the Junction Triangle. In this research, the tree inventory and questionnaire method were used. The questionnaire results show that respondents who moved in prior to 2007 view gentrification more negatively than residents who moved in after. The study found that there is a net growth of trees in the study area. Many invasive species have been removed, while more city recommended species have been planted. This research went on to find that trees in front of homes are in better condition than those planted on public land, and trees in front of improved homes are in better condition than those in front of unimproved homes. This is evidenced by the visible tree care and maintenance activities that are occurring on trees in front of housing but is absent from trees on public land.

Tree Care

A survey of households was conducted in six cities in the interior western United States to determine homeowners’ knowledge of tree biology and tree care and their knowledge and practice of topping. Tree biology and tree care knowledge was low, depending on the specific subject, and few respondents had any formal training in tree care. Respondents’ topping knowledge was moderate to poor if they had topped trees before, regardless of whether they received a topping-related educational brochure. Those who had not previously topped trees were fairly knowledgeable and the brochure increased knowledge in some cases. Topping was fairly commonly practiced, even by those who cared about trees, and often was done for safety and to improve tree appearance and tree health. Amongst those who had topped trees, the survey explored who performed the topping, why it was done, and their satisfaction with the practice. Examples of ways the tree care industry and others may be contributing to misunderstanding, such as inconsistent practices, are discussed. Recommendations are made for changing knowledge and attitudes about tree care as well.

Visual Symptoms

A tree stabilization system (TSS) is specified to promote stability and maintain tree posture at transplant. However, staking and guying can compromise tree health. The authors of the current study have investigated the effects of such stabilization systems on trees to inform urban forest planting specifications. Visual symptoms for tree health were recorded for 488 trees with and without TSSs in Guelph, Ontario, Canada. Results showing symptoms of stunted growth, death, and pest/disease were fewer on trees observed with TSSs. Health was negatively impacted by TSSs by producing more symptoms of girdled trunks, swelling, and wilting. Trees planted on public land were found to benefit from being stabilized while trees on private land expressed more negative health effects when observed with trunk support. Implications for urban forest professionals include limiting tree stabilization practice to site conditions where their use is warranted along with timely removal.

Available Information

Because researchers and land managers in Florida have been dealing with invasive species for decades, there is an abundance of resources available to the public regarding invasive species. Sometimes, the volume of available information can be confusing. This 6-page document aims to inform the general public, land managers, researchers, local and state policy makers, and others who seek guidance in accessing regulatory and nonregulatory non-native plant lists in the state of Florida. This publication explains the origins of the lists, meaning of inclusion on a particular list, and ways to access each of the lists. Written by Deah Lieurance and Lyn A.

Tree Care

Existing urban forest literature is strongest in its quantification and qualification of the benefits and care of trees, and not in its ability to assess the results of lack of investment in trees. This paper presents the results of a literature review on the “Costs of Not Maintaining Trees” commissioned by the ISA Science and Research Committee. The authors summarized the literature from within the field of arboriculture/urban forestry to answer the questions: What are the costs of maintaining trees and the urban forest? And, What are the costs of not maintaining trees? Present here is a detailed summary of the literature on the costs of maintenance and lack of maintenance for types of tree care commonly included in municipal budgets (planting, pruning, removal, pest and disease management) and a brief review of costs associated with less-studied types of tree care (including tree risk management; watering; mulching; fertilizing and nutrient management; staking, cabling, and bracing; tree protection; and infrastructure repair). The authors suggest that future literature should aim to examine the influence of maintenance regimes on costs and tree outcomes, including examining how the frequency, intensity, duration, and extent of tree maintenance activities is connected to the structure, function, and benefits of trees.
