Mechanisms of Forest Clearing Affecting Arboreal Snake Habitat Utilization

Abstract

Forest ecosystems are vital for sustaining biodiversity, and tree-dwelling snakes, as integral parts of forest food webs, are extremely sensitive to environmental alterations caused by deforestation. The goal of this study is to explore how deforestation influences the way treedwelling snakes in southern forests untilize their habitats. Through field investigations and data analysis, we found that deforestation led to a substantial reduction in canopy cover, directly decreasing the available habitat area for tree-dwelling snakes. The simplified vegetation structure, such as the decline in understory vegetation and hollow trees, impaired their foraging and reproductive abilities. Furthermore, the simplification of vegetation structure—such as fewer understory plants and hollow trees—impairs the snakes’ capacity to find food and reproduce. Additionally, habitat fragmentation resulting from deforestation restricted their movement range and gene flow. This research not only enhances our comprehension of the ecological consequences of deforestation but also provides a scientific foundation for formulating targeted conservation strategies for tree-dwelling snakes and their habitats.
