“…The average height ranges from 19 m (Platanus x acerifolia) to 10 m (Fraxinus excelsior). The calculated heights fitted well to the reachable heights given in the literature of the regarded species and do not overestimate their tree growth [20,32]. A wider variation between the maximum estimated height and the reachable height occurs for Fraxinus excelsior due to a relative small maximum DBH.…”

“…Only equations with minimum R 2 = 0.5 and p ≤ 0.001 (highly significant) were used. Furthermore, we calculated height and crown specific equations by defining three height and crown growth classes (tall/broad: >20 m tree height and >14 m crown width; medium: 20 to 15 m tree height, 14 to 8 m crown width; small: <15 m tree height, <8 m crown width) and summarizing all species depending on their typical growth characteristics on urban sites [20].…”

“…Citizens and the communal administration may be more concerned about the cultivation and maintenance costs of urban trees rather than recognizing their value for the urban ecosystem and human wellbeing [19]. Approaches for supporting planners and practitioners in planning the urban tree stock under the paradigms of multifunctionality and climate change are emerging [20]. Exact quantifications of ecosystem services may require complex, time-consuming and expensive field surveys.…”

Cooling Effects and Regulating Ecosystem Services Provided by Urban Trees—Novel Analysis Approaches Using Urban Tree Cadastre Data

Abstract:The provision of ecosystem services by urban trees is not yet routinely integrated in city administrations' planting scenarios because the quantification of these services is often time-consuming and expensive. Accounting for these welfare functions can enhance life quality for city dwellers. We present innovative approaches that may appeal to the numerous city administrations that keep tree inventory or cadastre databases of all trees growing on city property for civil law liability reasons. Mining these ubiquitous data can be a feasible alternative to field surveys and improve cost-benefit ratios for ecosystem service assessment. We present methods showing how data gaps (in particular tree height and crown light exposure) in the cadastre data can be filled to estimate ecosystem services with i-Tree Eco. Furthermore, we used the i-Tree Eco output for a noval approach which focus on predicting energy reduction as a proxy for cooling benefits provided by trees. The results for the total publicly owned and managed street trees in our study site of Duisburg (Germany) show that the most important ecosystem services are the removal of particulate matter by 16% of the city emissions and the reduction of 58% of the direct and thermal radiation in the effective range of the trees in the cadastre.

“…In order to properly design for tree, it is important to understand the value that urban trees can provide to any project. Benefits of urban trees are continuously discussed in previous research in term of environmental, social, economic, health, aesthetics benefits (Ramly et al, 2017;Vogt, 2017;Kondo ,2017;Salmond ,2016;Mullaney, 2015;Roy, 2012;Kadir, 2012;Chen and Jim, 2008;Buckelew et al, 2007;Nowak et al, 2006). All the benefits are contributed to creating urban fabric and improve quality of urban lifestyles.…”

This study explored the role of landscape architect in choosing trees for urban fabric. Two objectives have been formulated (i) to examine the process in selecting tree species among landscape architects and (ii) to determine the relationship between process and environmental constraints in selecting tree species for urban fabric. The findings showed that certain criteria of the environmental constraints are positively correlated and have strong relationship with tree selection process. The role of landscape architect is pertinent in tree selection. The findings of this research will contribute to process improvement in selecting tree species by landscape architects in the future.

“…However, rising temperatures will make cities in cooler climates more suitable for species that originate from warmer climates (Jenerette et al, ; Kendal et al, ). Similarly, in areas where trees receive irrigation, plants are unlikely to be constrained by ambient rainfall and will be less vulnerable to reductions in precipitation (Vogt et al, ). Despite the role that climatic suitability may play in shaping species choice and performance in urban areas, few comprehensive studies have explored tree species composition of urban forests across wide‐ranging climate zones (but see Jenerette et al, ; Ramage, Roman, & Dukes, ).…”

Societal Impact Statement Urban forests are recognized for the multiple benefits they provide to city‐dwellers. However, climate change will affect tree species survival and persistence in urban ecosystems. Tree failures will cause economic losses and jeopardize the delivery of societal benefits. The impacts of climate change will depend on the species’ resilience and adaptive capacity, as well as management actions which may ameliorate some of the negative impacts. Here, we assessed the potential vulnerability of Australia's urban forests to climate extremes. Our results can be used for future urban planning aiming to incorporate species that are well‐adapted to the hotter, drier climates expected with climate change. Summary Urban forests (UFs) are recognized for the multiple benefits they provide to city‐dwellers. However, global climate change—particularly predicted increases in the frequency and intensity of heatwaves and drought—will affect tree species’ performance and survival in urban ecosystems. Here, we assessed species composition and potential vulnerability of UFs in 22 Australian significant urban areas (SUAs) to heat and/or moisture stress. We quantified species’ realized climatic niches across their known distribution, and assessed the extent to which baseline climate in the SUAs where a particular species is planted fell within its niche. We used three environmental variables to group species based on their potential climate vulnerability. UFs varied in species composition and climate vulnerability across the continent. In general, neither climate similarity nor geographical proximity were good predictors of species composition among UFs. Of 1,342 tree species assessed (68.4% natives), 53% were considered potentially vulnerable to heat and/or moisture stress in at least one city where they are currently planted. Our results highlight the climate vulnerability of current plantings across Australian SUAs and can be used to direct future species selection that considers the species’ climate of origin and climatic niche. UF planning can incorporate species from SUAs with similar climates and with low vulnerability to contemporary, as well as future climate conditions. Species with high climate vulnerability, in contrast, may require more intensive management to avoid failure under future hotter, drier climate conditions.
