摘要

The Indian giant squirrel (Ratufa indica) is a large arboreal rodent endemic to the Indian subcontinent. The present study was conducted to assess the parameters contributing to the nesting tree selection by the species in the moist deciduous forests of Bondla Zoological Park, Goa, India. We achieved our objective by modelling the presence/absence of a squirrel nest on a tree against ten variables selected through field observations and literature review. The measured variables were tree height, tree species, vegetation type, tree girth at breast height, number of primary branches, number of secondary branches, canopy cover, presence of climbers, presence of parasitic plants, and canopy continuity. Our analysis indicated that all measured variables influenced the selection of a nesting tree by R. indica. The results of this study can aid in the development and implementation of conservation and management policies for this species in similar habitats within and outside the confinements of protected areas of the state.
