Abstract

A decade back, almost 300,000 km2 of forests in India were estimated to be potential tiger habitat. But consistent degradation and unsustainable anthropogenic pressures have adversely affected tiger presence in most of the forests outside the better protected tiger reserves. Here we use Geographic Information System data to analyze the degree of vegetation loss and landscape changes over the last decade (1998–2006), and ascertain the presence of tigers in a degraded forest like the Kawal Wildlife Sanctuary, Andhra Pradesh, India, by non-invasive fecal DNA analysis. Vegetation cover maps show a clear degradation of the sanctuary within a decade. DNA analysis of scat samples reveals tiger presence in areas where closed dense forest canopy has persisted with minimal human disturbance during the last decade.
