The danger of high temperatures is especially pronounced in cities due to the urban heat island effect. Trees can greatly reduce surface temperatures and mitigate the urban heat island effect through evapotranspiration and by reflecting solar radiation before it is absorbed by impervious surfaces. However, trees may also be physiologically susceptible to the effects of climate change as high temperatures exceed their physiological limits. In this study, we assessed how the urban tree community in subtropical Miami (Florida, USA) will be impacted by climate warming and how impacts will differ between native and exotic tree species. We calculated the thermal safety margin (TSM) in Miami for each of 235 tree species as the difference between the maximum temperature experienced by a species within its range and the current and future (2100) projected maximum temperature in the city. We also combined TSMs, a metric of resilience to heat, with each species’ drought, wind, and salt tolerance to identify species that are resilient to multiple relevant stressors. We found that by 2100 Miami will be too hot for 16–41 % of the tree species currently planted in the city, depending on the climate change scenario. Native tree species will be disproportionately impacted compared to exotics, likely because most exotic species originate in the tropics, whereas most species native to Miami are primarily subtropical or temperate. The species that are more resilient to multiple stressors include mostly native species, several of which are ideal shade trees. Urban greening initiatives should carefully consider tree plantings to optimize the long-term health of urban tree communities and the services that they can provide to cities in the future.</p></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"101 ","pages":"Article 128502"},"PeriodicalIF":6.0,"publicationDate":"2024-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142149293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To date, limited research has examined the landscape of NGOs working to advance green space equity via policy change. In this paper, we studied what kind of NGOs engage in green space equity policy advocacy in the US. We used topic modeling, keywords-in-context, and inferential statistics to analyze grant applications for a national initiative to fund green space equity advocacy, the first and only of its kind. We found that NGOs also advocate for several interrelated topics related to green space equity (e.g., environmental issues, social services), engage numerous policy actors in campaigns (e.g., politicians, youth), and use other strategies such as coalitions, power building, and research. NGOs working to address green space inequities also need to contend with other systemic issues affecting underserved communities (e.g., poverty, health disparities). Our findings can inform the work of public and philanthropic funders, local governments seeking partnerships with NGOs, and NGOs themselves.</p></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"101 ","pages":"Article 128503"},"PeriodicalIF":6.0,"publicationDate":"2024-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1618866724003017/pdfft?md5=1d96f2f4361f6ce56f099f63722acd44&pid=1-s2.0-S1618866724003017-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142149291","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective was also to investigate to what extent actual vegetation is in focus in this literature. The results highlight a low level of specificity when describing vegetation, concerning both spatial aspects and content, with general terms such as “nature” or vegetation types (trees/shrubs/grass, etc.) being common, leading to difficulties in interpretation and synthesis. A multitude of themes are present, describing different research foci. Several themes show limited interaction with other themes, such as the theme “microclimate”, which may be of notable relevance for future research because of global warming.

While free data sources like Copernicus Sentinel satellite data could be explored, there are a few studies illustrating its potential for mapping urban tree C. Here, the Sentinel 2 (S2)-derived Normalized Difference Vegetation Index (NDVI) was used to model CS for street trees in Brussels. In parallel, the WorldView 3 (WV3)-derived NDVI layer was also used for a similar study area to compare the CS mapping outcomes regarding dominant tree species. The accuracy level was around 90 % (R²=0.89, r=0.94, and RMSE= 97 kg) in the case of WV3 data, whereas it was about 60 % (R²=0.60, r=0.79, and RMSE = 189.6 kg), even with a coarse resolution regarding the S2 data. This study also shows the strength and scope of using S2 data over WV3 data, illustrating the convenience in terms of accuracy and cost-effectiveness compared to existing methods. The applied methodology could be utilized to monitor urban trees and predict the level of possible carbon sequestration, even considering a larger city like Brussels with a complex agglomeration. It could be a solid additional support for the authorities of European towns and developing countries, especially in terms of being cost-efficient and readily embraced by users.</p></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"101 ","pages":"Article 128495"},"PeriodicalIF":6.0,"publicationDate":"2024-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1618866724002930/pdfft?md5=d5e2b38137963deac52f0fc225ebab2d&pid=1-s2.0-S1618866724002930-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142137505","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are few studies from the Global South, and more specifically in Latin America. Given the high prevalence of crime in Latin American cities, the need to address social and environmental inequalities using nature-based solutions is urgent. This study examines crime and tree canopy cover through a series of spatial analyses for São Paulo city, Brazil, while controlling for potential confounders. We tested six levels of data aggregation that were combined with three different crime types and two denominators of crime, to account for spurious findings from Modifiable Areal Unit Problems (MAUP). Of the 36 models, a majority of 27 models (75 %) indicate a negative relationship between crime and tree cover canopy, while 4 models (11 %) show a positive correlation, and 5 models (14 %) suggest no statistically significant relationship. Our best models allow us to infer that 10 % greater tree canopy cover is associated with a 1.20 % fewer property, personal and total reported crimes, with statistical significance at the p &lt; 0.001 level. These findings support our hypothesis that there is a negative relationship between tree canopy cover and crime, with a stronger association observed for property crime than personal or total crime. The negative relationship persisted independently of the level of data aggregation, crime types, crime denominator and spatial models specifications (lag and SARMA), avoiding statistical bias of MAUP. The results follow the literature that have observed tree cover associated with lower crime rates, for different types of crime, while adding a new climatic and cultural context to the evidence base.</p></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"101 ","pages":"Article 128497"},"PeriodicalIF":6.0,"publicationDate":"2024-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142129624","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the current study was to develop soils that contain health-associated microbiota and are suitable for urban landscaping. Therefore, the potential of forestry- and agriculture-derived supplements in urban greening was investigated. Commercially available, peat-based lawn soil (standard substrate) was enriched with boreal forestry side streams (conifer needles, cones, pine bark, alnus leaves, moss debris, reed and manure), moss or side-stream based products (biochar, composted agricultural waste). The microbial communities of the standard and enriched substrates were followed in two year-long studies in which sod and grass were grown outdoors and indoors. Moss, conifer needles and reed retainded and increased the relative abundance of the phylum Proteobacteria and its classes, while <em>Alnus</em> litter and conifer needles supported the relative abundance of <em>Mycobacterium</em>. Temporal shifts in the relative abundance and richness of previously health-associated bacteria were evident. The method of enriching lawn soil with side streams appears to elicit desired shifts in health-associated microbial taxa. The results indicate that several agricultural and forestry side streams are suitable for shaping health-associated microbiota in commercially available soil. Further studies to explore the potential of side streams in immunomodulatory urban greening are recommended.</p></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"101 ","pages":"Article 128492"},"PeriodicalIF":6.0,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142137502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Whether or not urban landscapes can sustain diverse pollinator and plant communities is an important question to be addressed. Here, we investigated the influence of urbanization on plant-hummingbird interaction networks in a large tropical city, Belo Horizonte, Brazil. We recorded 13198 legitimate interactions between seven hummingbirds and 57 plant species across 12 local networks. Urban landscapes exhibited predominantly generalized networks, maintaining this pattern across varying vegetation cover and floral resource abundance. Although some functionally specialized hummingbirds with long bills were recorded performing more specialized interactions, urban environments did not generally support specialized networks. Nevertheless, network specialization did increase with the proportion of native nectar plants, emphasizing their importance for maintaining some specialized interactions. Furthermore, we observed a positive effect of plant richness, but not of flower abundance, on hummingbird abundance, indicating that it is not only the amount of flowers, but the diversity of floral resources that may be a key factor in maintaining hummingbirds. Therefore, promoting a diverse assemblage of native plants in urban green areas is crucial for sustainable pollinator communities. Our study highlights that while a biodiverse urban landscape will require careful urban vegetation planning considering both floral resource diversity and availability, vegetation cover per se may not be sufficient to mitigate the negative impacts of urbanization. Maintaining a diverse vegetation with different life forms, flowering phenology, and especially of native plants across the urban landscape is needed to create welcoming spaces for pollinators.</p></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"101 ","pages":"Article 128498"},"PeriodicalIF":6.0,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142149289","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To create high-quality urban natural environments, it is crucial to understand the residents’ perceptions, preferences and psychophysical health benefits concerning biodiversity. This study, employing various experimental designs, investigated the perceptions, preferences and restorative experiences of 695 participants concerning different levels of plant species richness and colour diversity in four typical urban green space types (lawn, forest, square and streetscape). The following discoveries were made: (i) The colour diversity carried by vegetation in lawns was an important basis for the public to identify plant diversity. Lawns with high richness achieved by different grass species (that have green colour) were not preferred by the public, and increased colour diversity that can be achieved by adding flowering plants (forbs) was preferred by people more than a single green lawn. The species richness of forests was positively correlated with public perception, preference and perceived restoration, with single green forests being preferred by the public. Additionally, people preferred vegetated environments over unvegetated squares or streetscapes. (ii) Participants’ perceptions, preferences and perceived restoration were positively correlated. Their preference for and perceived restoration from plant diversity depended more on their perception of it than on the actual species richness. (iii) Participants’ gender, expertise, physical condition, ecological knowledge, childhood living environment, frequency of use and accessibility of green spaces, natural orientation (connectedness), gardening, sense of security and well-being all influenced their perceptions, preferences and perceived restoration from plant diversity to varying extents. Significant distinctions were found between different forms of experimental design. Combining between-subject and within-subject designs could both control individual errors to some extent and avoid long-term effects on the participants compared to using either design alone. These findings provide a theoretical basis and practical approach for future biodiversity-oriented urban green space planning and management to better maximise the ecological and social service benefits of urban green spaces.</p></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"100 ","pages":"Article 128487"},"PeriodicalIF":6.0,"publicationDate":"2024-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142087310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
