We develop research focused on the environmental quality through a survey of herpetofauna in a threatened area with minimum data. The collected data supported by literature was used to predict the highest threat in the Prevab forest and to recommend a conservation area according to priority. The survey was conducted on three main sites: Senadam lake, camp area, and Buntu river. Each location was surveyed using a Visual Encounter Survey in a 1 km transect, from 7 to 11 p.m. for 3 days (21-23 October 2016). This study has identified 25 species herpetofauna from 76 individuals, consisting of 3 orders: Squamata, Anura, and Crocodilia. The highest number of individuals found were Chalcorana raniceps (n:18), Hemidactylus frenatus (n:7), Hemidactylus platyurus (n:10), Eutropis sp. (n:5), Cyrtodactylus yoshii (n:4), Crocodylus porosus (n:4), Hylarana erythraea (n:3), Varanus salvator (n:3). Two species were categorized as 'Threatened' species in the IUCN Red List, and one (Ptychozoon horsfieldii) was categorized as 'Data Deficient.' One species, Limnonectes paramacrodon, was categorized as 'Near Threatened'. There were 2 species categorized as Appendix II CITES: Varanus salvator and Crocodylus porosus. Only one species, Crocodylus porosus, was protected by Indonesia's regulation. Chalcorana raniceps and Limnonectes paramacrodon were found in high numbers in Buntu river, while the camp area was mostly visited by Hemidactylus platyurus, Hemidactylus frenatus, and Ptychozoon horsfieldii. Senadam lake was found to be the habitat for Crocodylus porosus. © 2017 Author(s).
