Abstract

Identification and documentation of rare, threatened and endemic species is important in the conservation of biodiversity. These species usually have specific ecological niches, edaphic gradients, and vulnerable habitats. Nine forest habitats of Peppara Wildlife Sanctuary, Kerala, India, were analysed for ecological niches and relative density of rare, threatened and endemic tree species using stratified random sampling techniques. A total of 151 tree species belonging to 51 families with 62 endemics (41 of endemism), 6 rare and 8 threatened species were documented
