Urban expansion transforms the availability and structure of habitats, shaping urban natural elements. This triggered a worldwide effort to reduce urbanization impact on biodiversity, mostly with biodiversity-friendly and less formal management in urban green areas. In this context, we evaluated the effect of lawn management promoting tall herbs on insects in urban parks. Moreover, we also tested the interplay of mowing regimes and green-area attributes, such as park size and tree distribution, by recording the insect species richness and the total and proportional abundances of several groups (i.e., honeybees, wild bees, wasps, hoverflies, non-syrphid flies, beetles, true bugs, grasshoppers, lepidopterans). The results from the first experimental year demonstrate that unmown sections increase insect abundance and species richness, while the regrowth after the first mowing of tall herbs was only moderately beneficial, compared to frequenlty mowed areas. Positive contributions by flower richness on the insect richness and by the aggregated tree distributions on insect abundance and richness were recorded. Negative relationships occurred between increasing graminoid cover and insect abundances and between park size and insect richness. Furthermore, most insect groups were promoted by plant height (except honeybees and flies) and they correlated with specific dominant plants in many cases. Overall, this study demonstrates the positive roles of tall herbs in urban parks, clarifying the influence of park attributes and lawn features, pointing out that a less intensive management regime with informal green areas could effectively enhance urban insect biodiversity.

The factors influencing urban plant diversity in tropical cities remain underexplored. To address this gap, we conducted comprehensive field surveys and remote sensing analyses in Danzhou, Hainan Province, focusing specifically on urban functional units. Our study quantified the diversity of trees, shrubs, herbaceous plants, spontaneous species, and cultivated species, employing spatial autocorrelation analysis to assess their relationships with land cover, socioeconomic factors, greening management practices, and landscape patterns. Our results revealed that recreational and leisure areas contained the highest proportions of urban green space, while transportation zones had the lowest. Herbaceous plants were predominant across key urban functional units, and cultivated species consistently outnumbered spontaneous species. Notably, the richness of tree species correlated positively with the age of urban construction, indicating a legacy effect. Additionally, effective greening management practices, such as watering and fertilization, were essential for enhancing plant diversity, and landscape pattern indices significantly affected species richness. These findings provide valuable insights for managing urban plant diversity in Danzhou and contribute to the understanding of the driving factors behind plant diversity in tropical urban environments.

Urban green spaces (UGS) are vital for urban sustainability, but unequal exposure to UGS can lead to serious health inequalities. The long-term drivers of inequalities in personal exposure to UGS and the underlying mechanisms remain insufficiently understood. This study measures trends in inequality in UGS exposure in 710 Japanese municipalities over a 20-year period (2000–2020). The direct and indirect effects of economic status, urbanization, and infrastructure investments on inequalities in UGS exposure were analyzed using partial least squares structural equation modeling while considering the mediating roles of land use, demographic, and greening factors. This study found that the distributional inequality in UGS exposure in Japanese municipalities has increased significantly over the past two decades. Economic levels, urbanization, and infrastructure investments drive UGS exposure inequality directly and indirectly through greening and population density. While these relationships may vary by period and region, UGS and population density remain key predictors. Given Japan's challenges related to population decline and aging, cities need to focus on population dynamics and the distribution and size of UGS based on specific economic conditions and stages of urbanization to formulate effective strategies for sustainable development.

Urbanisation often distances people from nature, impacting health and well-being. Urban rewilding reintroduces wilderness into cities, supporting biodiversity and reconnecting people with nature. This study investigates public perception of biodiversity and aesthetic preferences in rewilded urban sites, using Jiangyangfan Ecological Park in Hangzhou, China, as a case study. The park includes rewilded and semi-rewilded plots with varying degrees of human intervention. Participants, including non-experts and landscape architecture students, evaluated photos of the plots for species richness and aesthetic appeal. Results indicate a strong correlation between perceived and measured species richness for non-experts, though this correlation is weaker for students. Non-experts prefer semi-rewilded plots, associating higher species richness with higher aesthetic value, while students’ preferences do not vary significantly with species richness. The correlation between habitat management intensity and aesthetic preferences is weak for both groups, suggesting a balance between natural and managed landscapes can enhance public appreciation. The study highlights the public’s ability to perceive biodiversity and the importance of integrating public preferences in urban rewilding efforts. It underscores the need for nature education to improve biodiversity appreciation, promoting sustainable urban rewilding practices. Our results highlight the potential of semi-rewilding as a balanced approach within urban rewilding, helping to reconcile aesthetic and biodiversity goals in areas where they may conflict.

Systems theory highlights that stand structural attributes influence overall functioning. However, the relationship between these attributes and ecosystem multifunctionality, particularly in urban forests, remains poorly understood. This study uses regression analysis and a random forest model to assess the effects of 19 indicators of stand structure characteristics on ecosystem multifunctionality of urban forests in Changchun, a representative forest city in northern China. The structural characteristics are categorized into stand structure, herbaceous layer structure, and structural heterogeneity. Multifunctionality is evaluated based on carbon sequestration, rainfall interception, air temperature reduction, humidity enhancement, PM2.5 reduction, and noise reduction. Results indicate that both stand structural heterogeneity and stand density significantly enhance multifunctionality, with structural heterogeneity having the greatest impact, followed by stand structure and herbaceous cover. Thus, optimizing stand density, increasing structural heterogeneity, and maintaining sufficient herbaceous cover are crucial for improving urban forest multifunctionality. These findings offer important implications for urban forest management and the enhancement of urban environmental quality.

Brownfield greening (BG) is increasingly recognized as an important tool for improving the quality of life and urban sustainability in urban planning, yet our understanding of this topic remains limited. This paper aims to advance the state of knowledge of BG from the ecosystem services (ES) perspective and synthesize key findings to provide implications for integrating BG into urban planning. To achieve this aim, we conducted a systematic literature review of 58 papers, analyzing 1) general information, 2) ES provided by BG, 3) brownfield characteristics, and 4) targeted green spaces. Our findings indicate that BG has been garnering increasing attention in the academic field in recent years and showing a deeper integration with the ES concept, while most studies focused on developed countries rather than developing ones. Habitat and recreational services emerged as the most extensively discussed ES among the various identified ES. While some relationships were identified between brownfield characteristics and the delivery of ES, little research has directly investigated this connection and most studies lacked sufficient information on brownfield characteristics. The five main types of transformed green spaces identified in current research are general 'green space,' 'vegetated brownfield,' 'park,' 'woodland and forest,' and 'protected area'. For integrating BG into urban planning, we found that BG holds potential as a nature-based solution (NBS) towards multiple urban challenges and suggests applying comprehensive, dynamic management, planning and design tools to achieve sustainable BG in the future.

Accessing nature can significantly benefit mental and physical health. However, in England, individuals from low-income areas generally do not access nature to the same extent as those from affluent neighbourhoods due to a lack of private and public greenspace. In response, this research uses ethnography combined with Interpretative Phenomenological Analysis to explore the experiences of allotment gardeners living in low-income areas. The paper aims to (i) explore the possible wellbeing benefits of allotment gardens and (ii) examine the potential role of allotments in making low-income areas ‘just green enough’. Three themes were developed from the analysis. “It’s always going to be something which I associate myself with”: Connection to Self explores the sense of identity and empowerment participants experienced through allotment gardening. “It’s not just your allotment”: Connection with Others outlines the culture of sharing on site which connects gardeners and the challenges to integrating into the community. Finally, “I find the allotment a safe place”: A Space of Sanctuary highlights the importance of allotments as a safe and private place for participants to retreat to for mental wellbeing. The findings demonstrate the importance of allotment gardening within low-income areas for identity, community, empowerment and mental health and have implications for government and local councils by highlighting the importance of allotments for tackling the issue of greening low-income areas.

Plants produce diverse biogenic volatile organic compounds (BVOC) that contribute to ozone (O3) and secondary organic aerosol (SOA) formation. To minimize the negative impacts of urban greening on air quality, selecting species with low BVOC emission and reduced potential for O3 and SOA formation is essential. We evaluated BVOC emissions from eight tree species in an urban Atlantic Forest in São Paulo, Brazil, across wet and dry seasons, using a dynamic enclosure system and the ATD-GC-MS technique. Ozone formation potential (OFP) and secondary organic aerosol potential (SOAP) were estimated based on the quantification of 41 compounds, maximum incremental reactivity, and fraction aerosol coefficient. Our results indicated the presence of non-isoprene emitters. Ocotea odorifera and Byrsonima ligustrifolia were the lowest BVOC emissions during the wet season, with no detectable emissions. Conversely, Didymopanax angustissimus and Byrsonima ligustrifolia exhibited the highest emissions during the dry season (0.246 and 0.230 µg gdw⁻¹ h⁻¹, respectively). Hierarchical cluster analysis classified the species based on their BVOC emission patterns. Sesquiterpenes (SQTs) dominated emissions in both seasons, while monoterpenes (MTs) were emitted by all species only during the dry season. Oxygenated volatile organic compounds (OVOCs) emissions were higher in the wet season. Species such as Matayba elaeagnoides, Nectandra oppositifolia, and Alchornea triplinervia exhibited the highest OFP and SOAP during the wet season. In contrast, Ocotea odorifera and Cordia sellowiana contributed minimally to secondary pollutant formation in both seasons, highlighting their suitability for urban greening initiatives aimed at air pollution mitigation plans.

Because of the environmental and social benefits associated with urban greening, many cities around the world are implementing strategies to increase tree canopy cover, including along residential streets. However, procedures for developing and implementing these strategies do not always factor in public preferences, which can limit public acceptance. This paper explores public preferences for different characteristics of street trees. Where past studies have relied on capturing perceptions of street trees using rating scales for relatively few attributes, we apply best-worst scaling, which is a type of choice experiment, to assess preferences for 16 different tree characteristics. As the method requires trade-offs from respondents, it results in a systematic ranking of the tree characteristics considered, which represent different ecosystem services, physical attributes, and management requirements. We find that capacity to support local biodiversity and drought tolerance are the two characteristics that are most preferred. We also find that having visual appeal, requiring little maintenance, and having native origins are viewed favourably. Tree characteristics seen as less important include the size and growth rate of a tree, along with whether it holds cultural significance. Better understanding preferences for tree characteristics presents an opportunity for environmental managers to integrate tree species with more widely accepted attributes into urban greening programs.

However, procedures for developing and implementing these strategies do not always factor in public preferences, which can limit public acceptance. This paper explores public preferences for different characteristics of street trees. Where past studies have relied on capturing perceptions of street trees using rating scales for relatively few attributes, we apply best-worst scaling, which is a type of choice experiment, to assess preferences for 16 different tree characteristics. As the method requires trade-offs from respondents, it results in a systematic ranking of the tree characteristics considered, which represent different ecosystem services, physical attributes, and management requirements. We find that capacity to support local biodiversity and drought tolerance are the two characteristics that are most preferred. We also find that having visual appeal, requiring little maintenance, and having native origins are viewed favourably. Tree characteristics seen as less important include the size and growth rate of a tree, along with whether it holds cultural significance. Better understanding preferences for tree characteristics presents an opportunity for environmental managers to integrate tree species with more widely accepted attributes into urban greening programs.","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"15 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142816567","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}

Stormwater biofilter systems can provide at-source pollutant removal and runoff reduction. However, vegetation in biofilters systems can be prone to drought stress, reducing plant health and survival in between rainfall events. Mycorrhizal colonization has been shown to improve nutrient removal in stormwater biofilter systems, but it is not yet known whether mycorrhizal colonization of biofilter plants can improve their water use or resistance to drought stress. We used a pot dry-down experiment to determine whether mycorrhizal colonization differs among six common biofilter plant species and whether it improves their water use or changes their drought resistance. We measured evapotranspiration (ET) during a well-watered (WW) phase before commencing a water-deficit (WD) phase, where pots were no longer watered. Predawn and midday water leaf water potentials were measured when plants had effectively ceased ET. Water use during the WW phase ranged between 4.6 and 5.9 mm day-1 and there was no significant difference in evapotranspiration between inoculated and control treatments. Cumulative water use during the WD phase was also unaffected by mycorrhizal colonization. Species with greater biomass ceased ET earlier than those with less biomass. While greater colonization was correlated with greater biomass, there was no significant difference in biomass between control and inoculated plants. These results suggest that mycorrhizal inoculation does not improve plant water use or drought resistance in biofilters. However, as all plants were drought avoiders, they are unlikely to experience drought stress regularly, unless the period between rainfall events is substantial.
雨水生物过滤系统可以从源头去除污染物并减少径流。然而，生物过滤系统中的植被可能容易受到干旱胁迫，在降雨事件之间降低植物的健康和存活率。菌根定植已被证明可以改善雨水生物过滤系统中的营养物质去除，但尚不清楚菌根定植是否可以改善生物过滤植物的水分利用或对干旱胁迫的抵抗力。我们采用盆栽干燥实验来确定6种常见生物过滤器植物的菌根定殖是否不同，以及它是否提高了它们的水分利用或改变了它们的抗旱性。我们在水分充足（WW）阶段测量了蒸散（ET），然后开始缺水（WD）阶段，在这个阶段，花盆不再浇水。当植物有效停止蒸散发时，测量了黎明前和中午的水分叶片水势。WW期的水分利用范围在4.6 ~ 5.9 mm day-1之间，接种处理和对照处理之间的蒸散量没有显著差异。WD期的累积耗水量也不受菌根定植的影响。生物量大的物种比生物量小的物种更早停止ET。定殖量越大，生物量越大，但对照植株和接种植株的生物量差异不显著。这些结果表明，接种菌根并不能提高生物滤池中植物的水分利用或抗旱性。然而，由于所有的植物都是干旱回避者，它们不太可能经常经历干旱压力，除非降雨事件之间的时间很长。
