Ecological niches and amplitudes of rare, threatened and endemic trees of Peppara Wildlife Sanctuary

摘要

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. In the present study, habitats of Peppara Wildlife Sanctuary were analysed for ecological niches and amplitudes of rare, threatened and endemic tree species by stratified random sampling techniques. The study resulted in documenting 151 tree species belonging to 51 families with 62 endemics (41% of endemism), 6 rare and 8 threatened species.
