Abstract

Travancore Tortoises (Indotestudo travancorica) are endemic to the Western Ghats, south India. Landscape level surveys showed no clear habitat selection by the species. Therefore, we used radiotelemetry to study home-range size and fine-scale spatial movement habitat use of four tortoises from 2008-10. Minimum convex polygon home-range sizes of four tortoises varied between 5.2 and 34 ha. Tortoises spent a majority of their time in evergreen forest edge that had bamboo-lantana-grass. Eighty-two percent of the locations in the evergreen forest, and 95% of the locations in the bamboo-lantana-grass habitat, were at the edge of these habitats. Therefore at a fine scale, tortoises used the forest edge, possibly because it provided opportunities for foraging and thermoregulation.
