Summary

Large mammal populations in the Periyar and Agasthyamalai reserves of the Western Ghats, India were once contiguous but are now isolated by a mosaic of human-impacted habitat and linear barriers. Restoration of movement is essential to buffer their populations from demographic stochasticity and loss of genetic diversity. Past projects by FERAL have identified a 185 km2 linkage zone where movement corridors can potentially be restored. However, the precise locations, optimal habitat compositions, and conflict management strategies for small-scale movement corridors through this human-dominated linkage are unknown. Quantifying large mammal habitat preferences at a fine scale can help in the restoration of corridors and in mitigating human-wildlife conflict in this landscape.

Objectives

The objective of this project was to quantify large mammal habitat preferences at a fine scale, and thus, 

  1. identify optimal corridor locations, and
  2. identify the factors that influence animal use of a site.
