Forest edge has significant effects on plant species and trait compositions in urban forests. Species composition differs significantly between forest edge and interior, while species richness and functional diversity remain unchanged. The study emphasizes the importance of protecting interior habitats and reducing the creation of new edges in urban regions for biodiversity conservation.
Forest edges have significant effects on plant species and trait compositions. However, most current studies on edge effects are based on natural forests, and studies on edge effects in urban forests are still limited. Here, we set up 50 survey plots in Wuchao Mountain National Forest Park, an urban forest of Hangzhou, China. We tested how species composition changed with distance from the forest edge. Specifically, we investigated dispersalrelated traits for 86 species, and analyzed trait composition changes with distance from the forest edge. The NMDS analysis revealed a significant difference in species composition between forest edge and interior, but species richness and functional diversity remain unchanged. However, single traits showed higher divergence than expected. The percentage of fleshy-fruited species declined with distance from the edge, but plant abundance of mammal-dispersed and animal-dispersal seed mass was increased. The different trend in seed size of different dispersal mode and seed mass from edge to the interior within the community may be related to the loss of mammal-dispersed plant species at the forest edge. This suggests that edge effects have a high influence on functional traits in urban forests, but not on species diversity. Edges had significant effects on animal-dispersed species and trait composition of plant communities. Our study highlights the importance of maintaining forest integrity by protecting interior habitats in urban regions. We also recommend reducing the creation of new edges and increasing the buffer area for biodiversity conservation.
