“…Historically the main benefits of urban trees and forests relate to health, aesthetic and recreational benefits in industrialized cities. In addition, green spaces have provided people with subsistence for providing food, fodder, fuel, wood and timber for construction (Tyrvainen et al 2005). Selection criteria listed in this paper should be a basis for the selection criteria used in urban green space programs.…”

“…Environmental benefits do not relate solely to areas of woodland, however; smaller groups, avenues and isolated trees can equally improve environmental conditions in urban areas (Tyrvainen et al 2005). Konijnendijk (1999) investigated the urban forestry activities in some European capitals and declared that the social function is a priority at all cities.…”

ABSTRACT:The aim of this study is to select appropriate criteria such as ecology, economy, social and aesthetic for plantation in Isfahan city, Iran. In order to do this research, 19 questionnaires were distributed among the experts at the study area in 2013. Analytical Hierarchy Process (AHP) technique as a multi-criteria decision making was used for evaluation of urban forestry at this research. Expert Choice software was used for analysis. The results showed that the ecological criterion has the highest weight for urban forestry at Isfahan city and the aesthetic criterion has the lowest priority for urban forestry at the study area. According to the judgments of the decision makers, results also showed that the large parks have the highest priority for urban forestry and street margins have the lowest priority for urban forestry and green space.

“…The moderation of microclimates and improvement of environmental conditions by urban trees has been analyzed by several studies [9][10][11][12][13], with results highlighting the importance of trees for cities and the city climate. Therefore, urban forests can also become a key component to the adaptation of cities to climate change [14]. However, healthy and well growing trees provide the greatest benefits.…”

Abstract:The urban environment characterized by various stresses poses challenges to trees. In particular, water deficits and high temperatures can cause immense drought stress to urban trees, resulting in reduced growth and die-off. Drought-tolerant species are expected to be resilient to these conditions and are therefore advantageous over other, more susceptible species. However, the drought tolerance of urban trees in relation to the specific growth conditions in urban areas remains poorly researched. This study aimed to analyze the annual growth and drought tolerance of two common urban tree species, namely small-leaved lime (Tilia cordata Mill. (T. cordata)) and black locust (Robinia pseudoacacia L. (R. pseudoacacia)), in two cities in southern Germany in relation to their urban growing conditions. Marked growth reductions during drought periods and subsequent fast recovery were found for R. pseudoacacia, whereas T. cordata exhibited continued reduced growth after a drought event, although these results were highly specific to the analyzed city. We further show that individual tree characteristics and environmental conditions significantly influence the growth of urban trees. Canopy openness and other aspects of the surrounding environment (water supply and open surface area of the tree pit), tree size, and tree species significantly affect urban tree growth and can modify the ability of trees to tolerate the drought stress in urban areas. Sustainable tree planting of well adapted tree species to their urban environment ensures healthy trees providing ecosystem services for a high quality of life in cities.

“…Particularly, in highly populated industrialized cities, ecosystem functions that support health, aesthetics, recreation and carbon storing are significant benefit to urban dwellers (Bell et al 2005;Konijnendijk et al 2006;Liao et al 2013). Although these benefits are well known, they have not been adequately taken into account for urban forest planning (Tyrväinen et al 2005a).…”

“…These variations add an aesthetic quality to the urban landscape (Dwyer et al 1992;Tyrväinen et al 2005a). Aesthetic quality is defined as a value judgment based on the appearance of a landscape and a person's emotional response to it (Daniel 2001).…”

Urban forests form an important component of the urban environment. They make a significant contribution to landscape silhouettes due to species diversity and the differences observed within forest communities such as tree composition, size and form. Visual effects such as these are referred as aesthetic value. Therein, quantitative assessments of targeted forest structures that will optimize aesthetic values are vital during urban forest planning. However, the silhouette effect, which is an important component of aesthetic value, has not been extensively studied to date. This study aims to reveal the relationship between forest structure, the visual quality of tree composition and the different forms and sizes that create the silhouette effect. To this end, virtual landscapes of different structures were created using computer-assisted images. The forest structure was characterized by a Form Mingling Index (FMI) and Height Dominance Index (HDI). A Pearson correlation was applied in order to find the relationship between the landscape silhouette values through a perceptual test as well as the FMI and HDI. The results of the analyses showed that there was a strong positive relationship between the FMI and HDI (r = 0.78, r = 0.75, P \ 0.01, respectively) and landscape silhouette values. The combined effect of FMI ? HDI was found to have the highest relationship with landscape silhouette values (r = 0.80, P \ 0.01). In conclusion, FMI and HDI offer a rapid, cost-effective method which can be used by managers to assess the silhouette value of an urban forest landscape.
