Investigating tree resilience in response to the global urban environment is undergoing significant transformation due to climate change, necessitating an integrated approach to urban forestry and ecological management. This study, based on the Royal Botanic Gardens, Kew, synthesizes recent research on the impacts of urban heat islands, climatic variability, and species distribution to inform urban tree management strategies. Urban trees, particularly those from the Tilia genus, play a crucial role in mitigating urban heat and improving biodiversity. However, their efficacy is influenced by climate factors, necessitating careful species selection based on local climatic conditions. We explore the use of species distribution models (such as those provided by the WorldClim and TreeGOER databases) to predict suitable tree species for urban environments under future climate scenarios. These models account for factors such as temperature, moisture, and precipitation patterns. Additionally, we examine the environmental factors affecting plant growth, emphasizing the mechanisms of shading and transpiration in mitigating heat stress. The role of local climate zones and urban microclimates in influencing tree growth and health is also discussed. Urban green spaces, as evidenced in studies from cities like London and Paris, significantly affect local microclimates and public health. Effective urban forestry requires not only the selection of appropriate tree species but also consideration of their placement and maintenance to maximize ecological benefits. This review highlights the need for comprehensive, multi-dimensional strategies in urban planning to enhance urban resilience and sustainability in the face of climate change. Future research should continue to refine species selection criteria and develop adaptive management practices that address the complexities of urban ecosystems.
