This study assesses the feasibility of the rule’s three components—visibility of three trees from every building, achieving 30 % neighborhood canopy cover, and ensuring 300-meter walking access to 0.5-hectare parks—using geospatial analysis. We employ a combination of remote sensing data, local administrative records, and open-source global datasets to evaluate tree canopy cover, greenspace distribution, and accessibility under different scenarios. Our case study focuses on Surakarta, an intermediate city recognized as Indonesia’s most livable city. Results show that only 29 % of buildings meet the visibility requirement, 2 % are in neighborhoods with 30 % canopy cover, and 25 % are within 300 m of a greenspace. However, accessibility could increase to 79 % if all greenspaces were fenceless and high quality. Our findings highlight disparities in urban greening, as smaller residential buildings tend to have lower scores than larger office buildings. These results underscore the role of park governance in shaping access to green spaces and the persistent challenges of achieving the 3–30–300 targets. We propose place-based recommendations tailored for each urban commune and advocate for the adoption of the 3–30–300 rule as a target for national and local development planning to enhance urban green space accessibility and equity. This framework has the potential to be used in participatory planning processes for consensus-based siting of green infrastructure and nature-based solutions in cities in developing countries.</div></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"107 ","pages":"Article 128797"},"PeriodicalIF":6.0,"publicationDate":"2025-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143735131","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}

However, the representation of tree canopy hydrological processes is often simplified or overlooked in existing stormwater models. This study modelled and evaluated the stormwater runoff reduction potential of birch (<em>Betula pendula</em>) and pine (<em>Pinus nigra</em>) trees in three scenarios (i.e., birch, pine, and mixed planting) on a storm event basis using the updated Storm Water Management Model (SWMM) tree canopy module. The model effectively represents the rainfall interception process of both tree species during different phenoseasons, demonstrating strong correlations between simulated and observed throughfall (<em>r</em> = 0.97–0.99) and interception values (<em>r</em> = 0.72) across all storm events. The results indicate that implementing urban trees in the study area led to an average reduction of 20–25 % in runoff volume and 16–25 % in peak flow, depending on the scenarios and phenoseasons. The most significant runoff reduction benefits were observed in a mixed-species planting scenario and during the leafed season. This interplay between species highlights the advantages of mixed-species plantings in urban environments, where diverse tree characteristics can enhance hydrological performance. However, the effectiveness of trees is limited during intense, high-volume storm events, although they still provide tangible benefits of up to 13.2 % reduction. The relative contribution of canopy interception to runoff reduction is most pronounced during the leafed season, small to moderate storm events, and when trees are situated over directly connected impervious areas. Infiltration and storage beneath tree canopies are the dominant mechanism for managing and reducing surface runoff, accounting for over 20 % of the water balance. This study demonstrates that the stormwater reduction efficiency of urban trees depends on both above- and below-canopy processes and conditions.</div></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"107 ","pages":"Article 128792"},"PeriodicalIF":6.0,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143748437","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}

In this paper, we use historical and contemporary spatial data to quantify the extent of different types of grasslands across the late 19th-century and present-day Helsinki capital region, Finland. We assess the overall and spatially explicit changes in grassland extent between these periods and link these changes to patterns of land cover change, with spatial overlap analyses.

Changes in grassland extent in the study region comprise local increases and decreases between the two time periods examined, with land cover changes related to urbanization underlying both of these changes. Grasslands that remain in the study region are dispersed across a diverse set of land cover types, with urban land cover such as parks, sports fields, and road verges hosting the majority of contemporary grasslands.

The aims of this study are (i) to present a comprehensive database of LAI data over tree size for 15 urban tree species, and (ii) to evaluate seasonal LAI data for over 100 trees of six species in relation to species traits and location with hemispherical photography.

Furthermore, we found significant differences in seasonal LAI development and leaf emergence, influenced by species traits like light requirements, sprouting type, wood anatomy and foliage density. Leaf patterns followed the typical course of a steep increase from branch area index (BAI) values of 0.3 in spring to a maximum LAI of 4.0 in summer and autumn/winter values of 0.5 BAI/LAI. The influence of soil sealing on LAI was less pronounced, albeit statistically significant.

On the other end, the urban environment is challenging for trees for various reasons, such as water availability, humidity, and increased temperatures (currently exacerbated by current climatic changes). Street trees, however, are rarely chosen according to the benefits they provide or their ecological needs. In Italy, for instance, despite its high biodiversity, species used as urban street trees are relatively limited due to the limited availability of species on the market, historical or cultural preferences, and economic reasons. This study aims to develop a preliminary methodology for selecting native tree species, considering their ecological requirements and potential suitability for the urban environment, factoring in the future warming of temperatures. Our proposed methodology consists of culling species from floristic databases and applying a series of ecological and bioclimatic filters to obtain a list of species that can potentially be used as street trees. When we applied our methodology to Italian cities, we obtained a list of 190 native species (among which 44 species are already used as street trees) that can potentially be recommended for the urban habitat. On the other hand, our analysis highlighted an underutilization of several native species (39 species) and that many species (177) are not suited for the climatic context in which they are used. Our results also suggest a pool of species (22 already used as street trees and 19 not used) that, in the Italian context, can be better suited to withstand the expected temperature increases. The selection of species should primarily be based on their being native but also on their ecological requirements to increase urban biodiversity, reduce tree mortality, and reduce management costs.</div></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"107 ","pages":"Article 128784"},"PeriodicalIF":6.0,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143724411","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}

Through a detailed inventory, we mapped 639 urban greenspaces throughout Broward County, Florida — one of the most populous counties in the United States. We identified and categorized various physical attributes (N = 8 in total), including playgrounds, athletic facilities, and picnic areas and derived a ‘human utility index’. Concurrently, we assessed biodiversity by estimating relative species richness within an urban greenspace. We found little relationship between our human utility index and biodiversity. More specifically, when the index was broken down to its parts, we found a positive correlation between some attributes such as playgrounds, bodies of water, nature preserves, and dog parks with biodiversity, indicating potential synergies rather than tradeoffs. This alignment between our human utility index and biodiversity suggests that urban parks can effectively serve multiple values without necessarily sacrificing one for the other. Both the human utility index and biodiversity correlate with greenspace size, emphasizing the significance of larger greenspaces in accommodating diverse values.

However, existing research suggests that knowledge systems for GI globally have significant gaps that undermine the effectiveness of these investments. These include a narrow focus on limited functions while neglecting others and a lack of research on the decision-making processes that determine which GI functions are prioritized and where.

GI siting for stormwater management has a more robust and consistent body of literature with similar methodologies compared to that for heat risk mitigation, and the types of GI used differ between the two focus areas.
