The Peppara Wildlife Sanctuary is a protected area significant for its rich biodiversity and its role as a catchment for the Karamana River. Established in 1983, it spans approximately 53 square kilometers and has recently gained attention due to comprehensive monsoon bird surveys conducted by the Thiruvananthapuram Wildlife Division. The sanctuary is geographically integral to the Agasthyamalai Biosphere Reserve, a critical region for conservation efforts in South India.
