“…It may be useful to increase the value of biodiversity when designing new green areas or to restore existing ones, but choosing among plants that also provide an advantage in terms of reducing air pollution. Globally, cities are experimenting with different ways to increase and support tree species richness, thanks to environmental and land cover heterogeneity and socioeconomic factors, in order to deliver ecosystem stability and services [85].…”

The ecosystem services (ES) and human well-being are keywords that guide the Italian strategy on urban greening. The development of ES priorities linked to specific land uses help to guide the drafting of management plans. The aim of the research was to assess and map green areas ecosystem services and socio-demographic characteristics in Turin neighborhoods in order to identify where to improve the provision of ecosystem services and the socio-demographic conditions. The Preliminary Assessment Method (PAM) was used for the assessment of provision and regulating services based on land use. The Species-specific Air Quality index (S-AQI) was used to assess the regulating services provided by trees. Three socio-demographic characteristics were analyzed at the neighborhood level-age index, housing density, and % of economically assisted citizens. PAM results show that Turin provides more ecosystem services in peripheral areas of the city. Trees with high S-AQI values represent 21% of the censed trees. Not recommended trees are 18%. The neighborhoods with higher S-AQI values are not always characterized by a higher number of trees/km 2 or species richness. Results show that the northern part of the city is characterized by higher values of ES and socio-demographic conditions than the central-southern part. This aspect is related to the conspicuous presence of agricultural land uses and water bodies, together with the presence of tree species with a high S-AQI values and high or medium socio-demographic conditions. 57% of the neighborhoods present low results for both aspects. Actions to improve the quality of green spaces in those neighborhoods could have great effects on liveability. Future management and planning strategies for increasing citizens' well-being through urban greening should consider the proposed approach.Forests 2020, 11, 25 2 of 19 (ES), beneficiaries and potential mismatches with their location of supply, as well as on the quality and quantity of ES, are essential to make informed decisions for the proper management of natural resources [5]. Moreover, human well-being is positively influenced by the level of biodiversity present in urban and peri-urban green spaces [6], which must be maintained or increased through effective management of plant and animal species, improving the quality of existing habitats through management [7]. In addition, socioeconomic inequalities in health are less pronounced in people with greater exposure to green space than in those with less exposure [8].As many ecosystem services are provided by urban green spaces, these will need to be better managed and planned to ensure a high standard of living in urban areas [9]. For the assessment of ecosystem services in urban areas, several methods can be applied [10][11][12]. Some of them are based on spatially explicit biophysical indicators to analyze the spatial distribution of ES delivery [13], others on suite of models or web-based modeling platforms for the spatially-explicit assessment of ecosystem services [14,15], and fi...

“…This heterogeneous character, that is also important from an assessment and monitoring perspective, can better represent the variety of urban green space types. Furthermore, this study takes into consideration the call for greater attention to tree diversity in planning and management of urban areas [68] as evident from the number of indicators linked to biodiversity.…”

Green spaces and trees are fundamental for the sustainability of cities. The use of management and planning indicators for green spaces, including urban forests, have been proposed, but are rarely applied and their potential to provide ecological, social, and economic benefits is usually overlooked by policy makers and managers. Here, we apply a set of indicators describing green spaces and their variability in different urban units within the Basso Isonzo, an area of the city of Padua (northern Italy). Eleven indicators were selected based on their capacity to consider availability, accessibility and the preservation or increase of urban green spaces and tree cover. The value of indicators was standardized and enabled to have five classes indicating increasing performance. The study indicates green spaces’ heterogeneous conditions. Interestingly, the indicators commonly change moving from the city center to the outskirts. Monitoring through these indicators will enable understanding whether specific management and planning targets are met and, in the absence of these targets, identifying main trends over time. The proposed approach and indicators applied are simple to collect, analyze, and convey information. The indicators are related to relevant social, economic and ecological conditions pertaining to green spaces. The proposed indicators can therefore be used as a simple tool to guide decision-making with the aim of enhancing green spaces.

“…In urban ecosystems, what includes urban forests, the green spaces can bring some ecosystems services that contribute to a significant quality of life (GÓMEZ-BAGGETHUN;BARTON, 2013;MORGENROTH et al, 2016). In this time of environmental crisis, with particular reference to global warming, a high quality urban forest becomes even more important, considering that the vegetation mitigates the effects of climate change in urban areas and improves the quality of life (MORGENROTH et al, 2016).…”

The diversity and spatial distribution of trees on the Federal University of São Carlos campus were analyzed. Eighty percent of total individuals of studied area were visited and 130 species belonging to 106 genres and 46 families were founded, of which 51 species are native to the region and 79 exotic species. A satisfactory species diversity was found (H'= 3.89) for an urbanized area. Although the study reveals low dominance of species, the results indicate a same species individuals' aggregation, which all species with the highest abundance have an aggregated spatial distribution. The exotic species number present is bigger than the native species number and should be avoided, especially when it comes to potentially invasive exotic species. The analysis of species distribution in the landscape was a great help to identify the same species individuals' aggregation and to direct management activity on these regions, given the pests and diseases emergence.
