The diversity and distribution of herps in Anibong, Jordan, Mt. Pangasugan Range, were determined. Eight study sites with different habitat types and microhabitat composition were identified. Sampling was done using the visual encounter method and pitfall trapping on April 21-May 1, 2006. A total of seventeen herpetofaunal species belonging to six families (Ranidae, Rhacophoridae, Agamidae, Scincidae, Colubridae, Viperidae) were identified, of which eight (47%) are endemics. These endemic species include Limnonectes magnus, Platymantis corrugatus, Platymantis dorsalis, Brachymeles samarensis, Draco lineatus, Sphenomorphus jagori, Rhabdophis lineate and Trimeresurus flavomaculatus. One species, Limnonectes magnus is already in the near-threatened category. This shows that though the area is generally slightly disturbed, it still serves as an important habitat to endemic species which are very vulnerable to threats. The slightly disturbed lowland forest stream has the highest number of species, as well as, endemics. However, illegal and unsustainable harvesting of freshwater resources poses danger to the existing natural habitat and herpetofaunal composition of the area. Other local threats include agricultural activities such as abaca plantation, which causes fragmentation and loss of forest lands.
