Site details
Site description: There are some of encroachments, wildlife captures and illegal logging.
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance because it meets one or more previously established criteria and thresholds for identifying sites of biodiversity importance (including Important Bird and Biodiversity Areas, Alliance for Zero Extinction sites, and Key Biodiversity Areas) KBA identified in the CI/CEPF Conservation Outcomes poster for Sumatra [Sundaland Hotspot] (2007). Taxonomy, nomenclature and threat status follow the 2004 IUCN Red List.
Additional biodiversity: Danielsen & Heegard (1995) identified 193 forest bird species in this area including White-winged Duck Cairina scutulata, Black Partridge Melanoperdix nigra, Crestless Fireback Lophura erythropthalma, Crested Fireback Lophura ignita, Large Frogmouth Batrachostomus auritus, Large Wren-Babbler Napothera macrodactyla etc. and also significant taxa or endemic such as Banded Pitta Pitta guajana, Garnet Pitta Pitta granatina, Chestnut-capped Thrush Zoothera interpres, Trichostoma buettikoferi, Grey-breasted Babbler Malacopteron albogulare, Striped Wren-babbler Kenopia striata, and White-bellied Munia Lonchura leucogastra.There is no rectricted-range bird species identified in this area, although Trichastoma buettikoferi could be categorized as rectricted-range bird species (Andrew 1992), and the area could be qualified as secondary area for endemic bird area. Non-bird biodiversity: Panthera tigris, Tapirus indicus, Presbytis melalophos and Hylobates syndactylus, Balionycteris maculata, Megaerops wetmorei, Morina cyclotis, Aonyx cinerea, Elephas maximus, Neofelis nebulosa, fish species: Notochelys platynota, Scleropagus formosus, reptile species: Crocodylus porosus, Heosemys spinosa, Tomistoma schlegelii. And formerly recorded Cuon alpinus, Dicerorhinus sumatraensis . A new recorded flora species is Rafflesia hasseltii (Danielsen & Schumacher 1997, Colijn 1999).

Threats
Summary of threats to biodiversity at KBA: Buffer zone of this National Park is under logging concession, large area were alocated for oil palm plantation. There are more than 30 sawmills arround this area, which indicates that the swamill get the log supply from this area (Anon 1998, Danielsen & Schumacher 1997, Colijn 1999).
