Herpetofaunal diversity and endemism in selected caves of Sarangani Province and Lanao del Sur, Philippines

Amphibians and reptiles (herpetofauna) are essential components of the Earth’s biodiversity. This study was conducted to determine the species richness, endemism, diversity, and relative abundance of amphibians and reptiles in selected caves of Glan, Sarangani Province and Wao, Lanao del Sur. Herpetofaunal sampling was conducted using the modified cruising method. Eleven species of herpetofauna belonging to six families were recorded. Moderate diversity with more or less even distribution was documented in the cave sites. There were four (36%) endemic species documented of which two are Mindanao Faunal Region endemic and are of vulnerable conservation status. The presence of endemic and vulnerable species indicates the need to protect the caves and the surrounding forest patches.
