This dynamic process results in long-term ecological impacts and fosters complex biodiversity patterns, characterized by the co-existence of both cultivated and spontaneous species. While current literature predominantly focuses on broader land use/cover patterns and changes, there is insufficient attention to the indirect and secondary impacts on urban biodiversity that follow initial landscape practices. Using 38 urban parks in a high-density of built-up city, Shanghai, China as an example, this study examines how specific landscape practices, leave a lasting imprint on urban flora, particularly spontaneous plant species that thrive post-intervention. To better understand the impacts of different data types (e.g. compositional data), a suite of Mantel tests, Canonical Correspondence Analysis and Variance Partitioning Analysis was used at two design scales: the whole park and the finer, site scale. This study identifies 211 spontaneous plant species in 169 genera from 82 families. At the whole park scale, park area had the most significant positive correlation with spontaneous plant diversity, whereas patch density primarily influenced spontaneous plant composition. The study shows the crucial role of the “natural” landscape design style in fostering spontaneous plant diversity. At the site scale, factors related to water conditions, such as vertical stratification of the community, low-lying and canopy cover percentage, significantly impact the diversity and composition of spontaneous plant species. Importantly, our study reveals that cultivated plant species significantly influence the diversity of spontaneous plant assemblages, suggesting positive interactions at the whole park scale but shifting to negative interplays at the site scale. Our work facilitates a better understanding of the forces that (re)shape and determine the structural and functional attributes of an urban novel ecosystem and can inform landscape design to optimize urban biodiversity conservation.</div></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"107 ","pages":"Article 128744"},"PeriodicalIF":6.0,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143563202","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 observe an advanced trend of the start of the season (SOS), delayed end of the season (EOS), and extended growing season length (GSL) of urban vegetation along with rapidly increased impervious surface area percentage (ISA%) over the past three decades (1991–2000, 2001–2010, and 2011–2020). The changes in LSP caused by urbanization were most pronounced in North America, followed by Europe and Asia. Globally, vegetation exhibited a consistent trend of earlier SOS along the urbanization gradients, with an average advancement of approximately 2.14 days per 5 % increase in ISA. EOS showed a delayed trend along the urbanization gradients, with an average delay of about 0.74 days per 5 % ISA. The advanced SOS and delayed EOS consequently contributed to a prolonged GSL with an overall extension rate of 2.87 days per 5 % ISA.

Using two cities (Dublin, Ireland and Xi’an, China) with different sociocultural and geographic contexts as case studies, human responses to BGI were studied by developing a photo comparison experiment (PCE) leveraging 15 visual stimuli that reflect five BGI dimensions. The main findings demonstrate that 1) stronger perceived naturalness is preferred over reduced perceived naturalness in BGI, but an excessive sense of naturalness can result in a lower preference for BGI; 2) the preference for perceived naturalness implied in BGI is associated with the perception of BGI landscape component value; and 3) there is a discrepancy between the preference pattern (personal preference with affective reaction) and the acceptance pattern (cognitive or rational understanding of the suitability of BGI implementation based on nonaffective reactions). By generating place-specific knowledge and comparisons, this study contributes to the planning, design and management of urban BGI in Dublin and Xi'an and highlights the need to consider the specificities of each city in BGI design and management, providing insights for other cities in these regions facing the need for wider BGI implementation.</div></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"106 ","pages":"Article 128730"},"PeriodicalIF":6.0,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143479817","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}

Adjusting roadside vegetation has emerged as a crucial strategy to ameliorate the thermal conditions along roadsides. However, conventional methods are often limited by fixed vegetation types and layout schemes within a limited area, posing challenges in effectively responding to the diverse optimization needs of complex environments. To address this issue, this study proposes a multitype vegetation optimization model based on reinforcement learning. Using street view images, we extracted large-scale, high resolution tree-shrub-grass multitype vegetation. Simultaneously, the optimization and adjustment of the vegetation structure is formulated as a Markov decision process. A pretrained nonlinear model is used to construct a reward mechanism for the cooling effect, and then a reinforcement learning algorithm with the twin delayed deep deterministic policy gradient (TD3) is used for the optimization strategy. Empirical results reveal that in the primary urban area of Beijing, increasing tree density and reducing grass coverage are the most effective strategies for roadside cooling in high-density built-up areas. Conversely, increasing grass coverage is optimal for roadside cooling at urban peripheries. Furthermore, spatially integrated optimization led to a reduction in local land surface temperature (LST) of approximately 1–3 °C, with an average LST reduction of 1.04 °C across the study area. Densely clustered trees contribute to localized cooling effects, whereas dispersed grasses are more effective at promoting overall cooling. These findings offer valuable insights for the formulation of effective urban vegetation planning and management strategies aimed at enhancing the roadside thermal environment.</div></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"106 ","pages":"Article 128729"},"PeriodicalIF":6.0,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143474216","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}

Commensurately, eradication attempts of newly detected exotic pests are burgeoning, with many occurring in urban landscapes where pests are often first detected. While early detection of invading pests is critical to the success of an eradication program, there is a growing need to obtain social licence to operate during a biosecurity response, especially in urban landscapes where multiple stakeholders can hold divergent values on urban trees. Biosecurity measures to eradicate an exotic pest (e.g., tree removal or pesticide/biopesticide application) are often contentious in urban areas and have been identified as a limiting factor in eradication success. Gauging and gaining social licence for control measures in a biosecurity response is needed in advance of the next pest arrival. This review identifies key elements for attaining social acceptability of biosecurity measures before and during a biosecurity response in urban landscapes to assist community and biosecurity agencies prepare for the next exotic pest incursion. Several actions can be taken. Relevant stakeholders can be identified now, their expectations and knowledge base understood, and relationships formed to gain trust and participation in future responses. Understanding public acceptance of biosecurity measures will help gain and maintain social licence in different contexts and develop appropriate communication and engagement approaches. Raising stakeholders’ awareness of the risks and costs of biosecurity incursions and the value of eradication measures can be enhanced when using participatory or co-design approaches and subsequently increase social acceptability of response operations. Reviewing social alongside technical aspects of eradication programs can shed light on ways to improve future programs as well as programs in-progress to support operational success.</div></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"106 ","pages":"Article 128722"},"PeriodicalIF":6.0,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143487555","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}

This study encompassed three diverse UGS types across northern, central, and southern China, rendering 30 panoramic images for assessment. Sixty participants assessed these images across seven dimensions: beauty, comfort, color, complexity, liveliness, greenness, and safety. Integrating these multidimensional visual indicators, a generalized estimating equations (GEE) logistic regression model demonstrated superior performance over existing traditional models focusing only on spatial features, facilitating more accurate evaluations of LVQ perception. Moreover, herb plants (eye-tracking indicator), water ratio (image segmentation indicator), and number of materials (spatial feature indicator) were the most positive factors affecting human perception. Isolated planting style positively impacted the perception of greenness, and sky ratio negatively correlated with beauty perception. Additionally, openness levels of 20–80 % enhanced beauty perception, while openness above 80 % decreased liveliness but improved safety perceptions. Shrub species diversity positively correlated with perceptions of greenness and complexity, whereas single and dense shrub arrangements diminish perceptions of greenness and liveliness.
