Despite these pressures, urban landscapes can still support biodiversity, provide essential ecosystem services and contribute to conservation. Several metrics exist to characterize landscapes, but the spatial scale at which they are relevant depends on species ecology or on the ecological process of interest. Rome, one of Europe’s oldest cities, has experienced continuous urbanization over centuries while maintaining a remarkable level of greenery. This study explores the landscape structure in Rome using a multi-scale approach. We analyze key landscape metrics—Green Area Proportion, Edge Density, Shannon Diversity Index, and Edge Distance—across four spatial scales (10 m, 50 m, 250 m, and 1250 m), which are relevant for the ecology of a wide variety of plant and animal organisms that occur in the city. We show that these landscape metrics can be summarized by two major axes representing urbanization and fragmentation, respectively, and allow for grouping Rome green areas into three types (homogeneous green areas, highly impervious areas, and impervious surfaces interspersed with small green spaces). The high-resolution raster data generated in this study can lay the foundation to test how these axes at different scales and theresulting landscape types can shape urban species assemblages</div></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"110 ","pages":"Article 128849"},"PeriodicalIF":6.0,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144067222","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}

{"title":"Urbanisation and specifically impervious cover alter riparian plant communities in a rapidly urbanising landscape in the Himalayas","authors":"Karma Jamtsho,&nbsp;Mark A. Lund,&nbsp;David Blake,&nbsp;Eddie Van Etten","doi":"10.1016/j.ufug.2025.128862","DOIUrl":"10.1016/j.ufug.2025.128862","url":null,"abstract":"<div><div>Impervious covers, such as roads, pavements, buildings, and parking lots, prevent water infiltration, thereby increasing surface runoff. The expansion of impervious cover along riverbanks in urban areas poses a significant threat to riparian ecosystems by altering species diversity and composition through hydrological changes. As dynamic ecosystems at the interface between aquatic and terrestrial environments, riparian areas play a crucial role in aquatic ecology, particularly in terms of biodiversity, bank stability, nutrient dynamics, and hydrological processes. Employing plot-based floristic sampling, this study investigated the effects of urbanisation, particularly impervious cover (quantified as PTIA, Percentage of Total Impervious Area), on riparian plant communities in the rapidly urbanising landscapes of Thimphu City, Bhutan. Additionally, other environmental variables and soil chemical properties were examined to determine whether they confounded the impacts of PTIA. The results showed that PTIA had a significant impact on the diversity and composition of riparian plant communities. Overall, higher levels of PTIA supported a greater number of plant species, including exotic species, but exhibited the lowest α-diversity and reduced tree abundance compared to reference sites (<em>p</em> &lt; 0.001). These areas favoured <em>Rumex nepalensis</em>–<em>Equisetum</em> spp. community, while low PTIA supported the <em>Calamagrostis scabrescens</em>–<em>Elaeagnus umbellata</em> community. Significant changes in species diversity and community structure were observed at a PTIA threshold of approximately 60 % (<em>p</em> &lt; 0.05), indicating substantial ecological alterations beyond this point. Except for soil pH, which influenced plant communities independently rather than confounding PTIA’s effects, other environmental variables and soil chemical properties did not have any significant effects on riparian plant communities. Our study revealed that PTIA was the primary predictor for changes in plant communities in rapidly developing urban riparian landscapes. The relationship between PTIA and plant communities highlights the importance of considering PTIA in urban biodiversity management, as it can predict the extent of vegetated land required to sustain healthy riparian ecosystems. These findings suggest that rapidly urbanising cities can realign their urban development and riparian biodiversity management strategies by assessing existing impervious cover and establishing appropriate PTIA thresholds to balance urban growth with the conservation of riparian environments.</div></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"110 ","pages":"Article 128862"},"PeriodicalIF":6.0,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144105318","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}

We surveyed the current ecological value of these gardens and their potential for biodiversity across 878 healthcare institutions in northern Belgium in 2020. The majority of these healthcare institutions in our survey were interested in the effects of biodiversity on their care providers and recipients, and 70 % of the healthcare institutions indicated they were willing to enhance the biodiversity of their garden. Only one in three healthcare institutions consciously used their garden as part of therapy. Most of the respondent institutions (96 %) had one or more green elements on their premises. Trees (89 %) and short-cut lawns (87 %) were most common, while flower meadows appeared to be relatively scarce (17 %). We looked at each garden’s potential to provide a suitable environment for target species or target groups to fulfill their lifecycle, which we explored for three examples: butterflies, aboveground nesting bees and the alpine newt (<em>Ichthyosaura alpestris</em>). Almost half of the gardens (45 %) had the potential to provide a suitable environment for butterflies, approximately one-third of the gardens (31 %) for the aboveground nesting bees and less than one tenth (9 %) for the alpine newt. The commonness of short-cut lawns, a green element characterized by high management costs and low biodiversity value, shows that there is room for green elements with a higher ecological value within the gardens. We identified flower meadows as a green element with a high potential of increasing the garden biodiversity. Turning short-cut lawns into species-rich flower meadows may be an answer to the biodiversity interest of the healthcare institutions.</div></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"109 ","pages":"Article 128848"},"PeriodicalIF":6.0,"publicationDate":"2025-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143911660","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 validate this discrepancy, we applied the same laser scanning and modeling methods to both LSTs and forest trees. Regression analysis confirmed that LSTs have significantly greater woody volumes than forest trees. However, this difference diminishes with increasing height, resulting in converging volumes in the tallest height class.

We integrated GPS data, Google reviews, and street-view images, applying natural language processing (NLP) and machine learning to analyze sentiment, comment topics, and environmental features, with partial dependence plots (PDP) exploring correlations with visitation patterns. Results reveal both park and business visitation patterns were significantly altered by the COVID-19 pandemic, impacting behaviors and emotional needs. There are significant differences in the usage and perception of parks and commercial areas. Parks, with their natural landscapes, offer restorative and emotional experiences, while business environments cater to functional and service-based needs. Environmental factors better explain park visitation, while sentiment and comment topics better explain business visits. Green spaces demonstrate greater crisis resilience than business areas through their environmental benefits and adaptability.
