Amphibian and reptile diversity in Mt. Kalatungan Range Natural Park, Philippines

Abstract

Herpetofauna inventory was conducted in the montane forest of Mt. Kalatungan Range Natural Park. Sampling plots were established in the lower montane at 1200 to 1400 m above sea level and upper montane at 1400 to 1600 m above sea level. Using a combination of pitfall trap and visual encounter methods, a total of 202 individuals were recorded belonging to 15 species, nine families and 12 genera, six of which are Mindanao endemic species. Five species belong to the IUCN Red List, which includes Limnonectes magnus, Ansonia muelleri, Ansonia mcgregori, Philautus acutirostris and Rhacophorus bimaculatus. Richness and diversity indices were consistently higher in the upper montane than in the lower montane. Similarity index of the two sites was only 26%, which implies that herpetofauna have specific habitat and food requirements for their survival. Threats in the area include habitat disturbance due to forest fire and conversion of forest to agriculture. These threats should be the focus of conservation efforts of local government units and the community to protect the habitat of these wildlife.
