We found that amendment reduced soil compaction, as indicated by a soil penetrometer, and bulk density, compared to sites without soil amendment. Amended soils exhibited higher water holding capacities, soil respiration values, as well as organic matter, soil protein, total nitrogen, total carbon and organic carbon contents. Compared to trees growing on sites without amendment, trees planted in amended soils exhibited larger trunk diameters, increased canopy height, longer shoots and leaves, increased leaf areas and leaf greenness, as well as more roots overall and roots growing deeper in the soil profile.

We found that the average emission intensity in these neighbourhoods was 11.51 t/km² (0.81–96.11 t/km²), similar to forested areas. The majority of the trees (92.39 %), accounted for 80.33 % of the tree species emit BVOCs in the sampled neighbourhoods. The emission fluxes of BVOCs differed greatly among neighbourhoods, affected by their social-economic characteristics. For example, more recently developed neighbourhoods exhibited higher emission fluxes of BVOCs, and average BVOCs first increased with housing prices and distance to the city centre and then decreased. The higher BVOCs emissions in neighbourhoods is likely affected by the increased selection of ornamental plants with high BVOCs emission rates. The results suggest the importance of considering the functional characteristics of plants, such as BVOCs emission rates, for promoting environmentally friendly and healthy urban neighbourhoods, when selecting tree species for landscaping in urban neighbourhoods.</div></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"108 ","pages":"Article 128841"},"PeriodicalIF":6.0,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143890944","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}

However, the impact of birdsong type and noise on the avian soundscapes and their contribution to landscape aesthetic quality remains largely obscure. This poses challenges for accurately modeling and projecting sound-induced changes in soundscape and landscape quality for landscape planning and assessments. This study aims to explore how birdsong type and noise (vehicle and wind turbine) influence perceived soundscape and landscape quality through a public experiment. Additionally, it examined the moderating effects of demographic characteristics (gender, age, and education levels) on these influences. Results show that evaluations of both soundscape pleasantness and eventfulness vary significantly with birdsong types. Increasing birdsong diversity did not necessarily enhance the soundscape pleasantness but significantly elevated soundscape eventfulness. Both noises substantially reduced the pleasantness of birdsong, though water sound modestly mitigated these impacts. The significant impact of birdsong on enhancing landscape naturalness was considerably weakened by vehicle noise. Gender significantly moderated soundscape pleasantness across birdsong types, while education level significantly moderated the noise-decreased landscape naturalness. Pairwise comparisons reveal a higher acceptance of vehicle noise over wind turbine noise among participants, and females and higher-educated participants were more sensitive to the noises. Besides, visual-only stimuli were more likely to cause differences in ratings of landscape uniqueness across subgroups. Such results highlight the crucial role of birdsong type in soundscape perception, the disruptive impact of noise on the contribution of birdsong to soundscape and landscape quality, and the importance of inclusively considering diverse user demands. This study can advance the understanding of soundscape-landscape relationships and usefully inform soundscape design, landscape planning, and environmental impact assessments.</div></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"108 ","pages":"Article 128838"},"PeriodicalIF":6.0,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143896071","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}

Trees take time to grow, so historic neighborhood conditions explain, in part, present-day conditions and the inequitable distribution of tree canopy and associated benefits. In 1934, the Federal Housing Administration (FHA) was created to help develop new housing and promote homeownership by insuring home loans, and consequently helped shape urban development. In 1937, the FHA ranked neighborhoods in Washington, DC, and the greater metropolitan area based on various neighborhood characteristics, including the racial composition of inhabitants, using the letters A through H. A-E areas were associated with white residents. From 1934–1962, nearly all (98 %) of the loans the FHA insured went to white borrowers. We asked if tree canopy cover (which provides benefits) and impervious surface cover (which is deleterious) is associated with the rank-order of the FHA’s neighborhood letter grades. High-resolution, high-accuracy land cover data from the Chesapeake Conservancy and FHA grade data from the Mapping Segregation Washington, DC project were used to examine and test these relationships with non-parametric Kruskal Wallis and Wilcoxon Rank Sum statistical tests. The percentage of tree canopy cover was significantly greater in high-ranked areas than lower, and impervious surface cover was more abundant in lower-ranked areas. The significant relationships persisted in sensitivity analyses using more encompassing definitions of tree canopy cover and impervious surface.

They are characterized by a high diversity of plant species, which explains their multi-functionality. A total of 119 homegardens in Bogotá, the capital of Colombia, were surveyed to assess their functional plant diversity. Semi-structured interviews were employed to document the socioeconomic status of the homegarden managers. A total of 253 plant species and their associated uses were documented. Hierarchical cluster analysis identified three distinct categories of homegardens based on the utilization of plant species: food, ornamental, and multipurpose. The results also revealed significant associations between cluster categories and agrobiodiversity, household size, and geographic location of the gardens. Food gardens had significantly lower plant diversity than the other clusters, and species were more evenly distributed in multipurpose gardens than in ornamental gardens. The predominance of lower socioeconomic respondents in the management of food-focused homegardens underscores their role as a crucial source of sustenance for underprivileged communities. In contrast, ornamental gardens, which are more prevalent in affluent areas, prioritize aesthetic values. In general, homegardens embody multifunctional spaces characterized by rich agrobiodiversity, meticulously adapted to the unique requirements of the households that manage them. The insights garnered from the study of agrobiodiversity in urban gardens hold significant potential to enhance management of urban green spaces and the well-being of their owners.

This study utilized multi-temporal mobile signal data from Shanghai to quantify the exposure intensity (<em>EI</em>) and density (<em>ED</em>) for forests and grasslands. These metrics addressed the gap by revealing spatiotemporal variations in exposure preference (<em>EP</em>) and related socioeconomic influences. Specifically, the study addressed two key questions: (1) Do urban residents exhibit preferences between forests and grasslands in terms of <em>EI</em> and <em>ED</em>? (2) How do socioeconomic features influence these preferences? Results showed: (1) Forests had almost double the annual <em>EI</em> (542.86 p/h) and <em>ED</em> (2.69 p/m²/h) of grasslands (P &lt; 0.001). However, grasslands in central regions exhibited significantly higher <em>ED</em> (13.60 vs. 11.83 p/m²/h; P &lt; 0.001).
