In urban settings, where closely-related native and non-native ornamental trees are often grown in close proximity, understanding how stoichiometry varies with nativeness or relatedness would be useful for urban planners trying to preserve ecosystem function. Here, we use leaves and needles from pairs of close relatives grown within a single urban arboretum to determine how stoichiometry varies between native and non-native trees within the same genus (congeneric species), representing a broad phylogenetic diversity that includes angiosperms and gymnosperms spread across four orders, five genera, and ten species. Additionally, we examined associated soil chemistries as a control. We find that stoichiometry is principally dictated by relatedness, and not by nativeness. Accordingly, prior observations that non-natives have fewer consumers and food web connections is likely not due to nativeness, but other traits. We suggest urban planners should increase phylogenetic diversity of native tree species to maximize the chemical composition of the trees that form the base of many urban food webs.</div></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"113 ","pages":"Article 129050"},"PeriodicalIF":6.7,"publicationDate":"2025-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145108690","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}

This review explores the role of urban vegetation in mitigating air and soil pollution, using Italy as a representative case study. Air pollution - specifically particulate matter (PM), nitrogen dioxide (NO<sub>2</sub>), and tropospheric ozone (O<sub>3</sub>) - remains a critical health concern in urban areas, while soil contamination by heavy metals and organic pollutants continues to degrade ecosystem functionality. We examined the mechanisms by which urban greenery mitigates these pollutants, focusing on species-specific traits, functional planning, and integrated monitoring strategies. To bridge research and practice, a new strategy for urban greenery planning is proposed, presented here as two case studies. The case first demonstrates an innovative air quality management approach in Florence, combining high-resolution satellite imagery with a new simple biophysical modeling framework (FlorTree model) to evaluate species effectiveness in pollutant removal. The second case synthesizes field-scale phytoremediation projects across Italy, showcasing how selected tree, shrub, and herbaceous species can remediate contaminated urban soils while providing co-benefits such as biomass production and biodiversity support. These findings highlight the global relevance of urban forestry as a low-impact, cost-effective strategy to enhance environmental quality and public health. By integrating green infrastructure into urban policy and land use planning, cities can optimize air and soil remediation, promote ecosystem resilience, and contribute to climate adaptation goals. The review underscores the need for interdisciplinary collaboration, long-term monitoring, and policy alignment to fully harness the potential of urban forests in addressing complex urban pollution dynamics.</div></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"113 ","pages":"Article 129066"},"PeriodicalIF":6.7,"publicationDate":"2025-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145093873","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}

Accurate segmentation of individual trees is a critical procedure in this task. However, traditional manual methods are labor-intensive and resource-demanding. In contrast, individual tree segmentation based on LiDAR point cloud data offers a practical and efficient solution. While recent advancements in deep learning-based point cloud instance segmentation and tree detection have achieved remarkable progress, previous methods have focused on semantic segmentation and ignored instance-level tree recognition in both urban and forest environments. Furthermore, the overlapping of tree crowns makes it difficult to accurately delineate individual trees from point clouds, posing a persistent challenge for achieving high accuracy and efficiency in individual tree extraction. To address these challenges, we propose an effective individual tree segmentation method capable of accurately extracting single trees in urban and forest scenes. The proposed approach consists of two primary steps: (1) We design the Semantic-Driven Instance Clustering to combine the semantic prior with the instance embeddings. (2) We introduce the Online Semantic Clustering for intra-class potential semantic discriminability, improving the instance representation within the same semantic class. The method is evaluated and validated on point cloud datasets from urban and forest environments, demonstrating its ability to produce accurate individual tree segmentation. The F1-score achieves 80.26% and 79.5% in Paris-Lille-3D and FOR-instance datasets, respectively, demonstrating the effectiveness of our approach. Building upon the segmented individual trees, we further estimate key 3D tree parameters to support subsequent vegetation inventory, management, and sustainable development applications, providing theoretical and methodological support for policy-making, planning, and design.</div></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"113 ","pages":"Article 129018"},"PeriodicalIF":6.7,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145095489","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}

Using a cross-sectional design with data from 2022, the variability in NatureScore™ was analyzed concerning the percentages of students from different racial backgrounds and those participating in free or reduced-price lunch (FRPL) programs. Multiple linear regression and bootstrap ANOVA were conducted to assess these relationships. Results show significant disparities: NatureScores™ are higher in schools with lower percentages of economically disadvantaged students and higher percentages of White students, indicating irregular distribution of nature across the U.S. Because NatureScore™ is calculated from 1-km buffers, our estimates reflect equity in the surrounding outdoor environment rather than indoor spaces or on-campus micro-features (like playgrounds, gardens). In urban areas, the gap between low and high socio-economic status schools can reach up to 25 points on a 0 (deficit) to 100 (utopia) NatureScore™ scale. Rural schools also show a consistent decline in NatureScore™ with increasing levels of economic disadvantage, although the differences are smaller (approximately 2.5–5 points) than those observed in urban schools.

Thematic analysis revealed four domains of park functions affected by others: being alone, appreciating nature, being with others, and appreciating urban/cultural life. Importantly, within these domains, functions could be influenced in different ways: positively (e.g., interaction with unfamiliar others), negatively (e.g., escaping social distress), or not prominently (e.g., interaction with familiar others, appreciating architecture). A key theoretical contribution is the identification of <em>parallel shared experience</em>, where the mere co-presence of others, without direct interaction, can foster a positive atmosphere. Contextual factors, such as spatial arrangement, safety, and personal orientations, further influence the role of others.

In China, this issue is particularly critical, with the urbanisation rate increasing from 17.9 % in 1978 to over 67 % in 2024, driving rapid land use transformation and reshaping the design and functionality of public spaces. Community parks (CPs) play a vital role in these areas in enhancing liveability and socio-ecological resilience. However, while policies increasingly emphasise the importance of green spaces, their quality and alignment with residents’ needs remain underexplored. This study examines the role of CPs in Wuhan’s URFAs by analysing park usage patterns, resident satisfaction, and functional design elements. Using structured questionnaire surveys (n = 452), the findings reveal that: (1) CPs within a 1,000-meter or 15-minute walking radius significantly enhance accessibility and utilisation; (2) resident satisfaction is influenced by infrastructure quality, particularly the availability of toilets, fitness equipment, and well-maintained facilities; and (3) CPs do not meet diverse community needs, highlighting a gap between quantity-based provision and quality-driven usability. This underscores the significance of prioritising functionality, inclusivity, and user-centred design. In response, this study advocates for a shift from a supply “quantity” driven approach towards a “quality” first planning approach, emphasising participatory design and people-centred approaches to optimise CP infrastructure. By providing empirical evidence, this research contributes to the discourse on urban liveability enhancement and offers insights for improving green space planning in rapidly urbanising regions.</div></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"113 ","pages":"Article 129055"},"PeriodicalIF":6.7,"publicationDate":"2025-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145060157","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 purpose of the research has been to map the measures taken in the Lower Silesian Voivodship to protect trees of high biocultural value and assess the effectiveness of those measures. The tree protection efforts of Lower Silesian communes from 2009 to 2023 were examined through an analysis of local government resolutions pursuant to which formal protection was granted to or revoked from trees. Additionally, spatial distribution and frequency analyses were used to evaluate the effectiveness of these actions across different types of communes and subregions, while the diversity of protected tree species was assessed using the Shannon–Wiener index. An analysis of legislative acts demonstrated that between 2009 and 2023, more than 60 % of Lower Silesian communes did not show a tendency to formally protect trees. Moreover, over 70 % of urban communes solely focused on revoking tree preservation orders. In the Wrocław subregion, the highest number of communes that officially protected trees and the widest variety of tree species under new preservation orders were documented. The research showed that typically only a small number of tree species is protected, with 30 % being <em>Quercus robur</em>. The efforts made in Lower Silesia to protect ancient and valuable trees may be deemed inadequate. Between 2009 and 2023, communes more frequently revoked tree preservation orders than granted them and they granted protection. The study identified the areas most at risk of losing bioculturally valuable trees. Moreover, such a significant contrast in actions undertaken across subregions indicates the need for further in-depth research on tree protection throughout Poland.
