Exploring the relationship between tree traits and microhabitat richness in urban greenspaces of Nagpur city, India

Urban trees are essential for sustaining biodiversity and delivering key ecosystem services within rapidly urbanising cities. Nevertheless, the maintenance and protection of healthy trees that can accommodate high habitat diversity must be ensured. The present study explored the relationship between tree characteristics such as size, health, nativity, location, and microhabitat richness in urban greenspaces and nearby highway roads in the fast-growing Nagpur city, India. Data from 203 trees (both native and non-native species) across parks and roads, revealed distinct patterns in Tree-Related Microhabitats (TreMs). Tree size and health were identified as the most influential predictors of microhabitat richness, with larger and healthier trees supporting a greater diversity of microhabitats. Contrary to traditional assumptions, non-native trees exhibited slightly higher microhabitat richness than native ones, suggesting their adaptability and potential contributions to ecology in urban environments. Spatial placement of trees in parks or along motorable roads did not significantly influence microhabitat richness, indicating that tree-level factors have a more substantial role. ... mehrThe present study on TreMs in India sheds light on the significance of conserving urban greenspaces and trees, with an emphasis on ensuring the conservation and restoration of urban greenspaces.
