	Phnom Prich Wildlife Sanctuary (PPWS) is located in the west of Mondulkiri Province, northeastern Cambodia. The site was first designated as a forest reserve by King Sihanouk in 1962 to protect the wild bovine species, Kouprey Bos sauveli. In 1993 the site was designated as a wildlife sanctuary (Channa & Gray 2009). PPWS covers 2,225, more than 15% of the total area of Mondulkiri province. The area is characterised by higher elevation and relief in the southeastern Laoka Hills portion, and lowlands in most of the sanctuary (Channa & Gray 2009). The forest in PPWS is part of one of the largest relatively pristine landscapes in mainland Southeast Asia, comprising a mosaic of dry dipterocarp forest and woodland, evergreen forest and semi-evergreen forest (Channa & Gray 2009). Although the flora and fauna of PPWS have not been adequately studied the site appears to contain populations of a number of species of global conservation concern, including Banteng ''Bos javanicus'', Jungle Cat ''Felis chaus'', Giant Ibis ''Thaumatibis gigantea'' and White-shouldered Ibis ''Pseudibis davi- soni'', ''Gyps'' vulture spp. and Siamese Crocodile ''Crocodylus siamensis'' (Channa & Gray 2009). An unknown number of Indochinese Tiger ''Panthera tigris corbetti'' are also present at the site (Channa & Gray 2009).		Phnom Prich Wildlife Sanctuary (PPWS) is located in the west of Mondulkiri Province, northeastern Cambodia. The site was first designated as a forest reserve by King Sihanouk in 1962 to protect the wild bovine species, Kouprey Bos sauveli. In 1993 the site was designated as a wildlife sanctuary ([[#R01485\|Channa & Gray 2009]]). PPWS covers 2,225, more than 15% of the total area of Mondulkiri province.

	Based on a survey in 2008, 149 (95% CI range: 15-273) gibbon groups inhabit PPWS. This includes 89 groups in semi-evergreen forest; 18 groups in riparian semi-evergreen forest; 36 groups in evergreen forest and 6 groups in riparian evergreen forests (Channa & Gray 2009). Assuming an average group size of 4 individuals and ignoring non-mated individuals, the population estimate for the site is approximately 600 individuals (Channa & Gray 2009).

	Key threats to yellow-cheeked crested gibbons within PPWS appear to be habitat loss and degradation caused by legal and illegal extractive activities, primarily gold mining and selective logging (Channa & Gray 2009). In addition, habitat degradation associated with gold mining includes harvesting of wood, for fuel in mineral processing and for the construction of stairs and supports for underground mines (Channa et al. 2009). Survey teams in 2008 recorded evidence of illegal logging and associated infrastructure in the reserve. Most loggers appeared to be from outside Mondulkiri, and targeted ''Afzelia xylocarpa'', a globally threatened and valuable tree species (Channa et al. 2009).

The site was first designated as a forest reserve by King Sihanouk in 1962 to protect the wild bovine species, Kouprey Bos sauveli. In 1993 the site was designated as a wildlife sanctuary (Channa & Gray 2009). PPWS covers 2,225, more than 15% of the total area of Mondulkiri province.

Based on a survey in 2008, 149 (95% CI range: 15-273) gibbon groups inhabit PPWS. This includes 89 groups in semi-evergreen forest; 18 groups in riparian semi-evergreen forest; 36 groups in evergreen forest and 6 groups in riparian evergreen forests (Channa & Gray 2009). Assuming an average group size of 4 individuals and ignoring non-mated individuals, the population estimate for the site is approximately 600 individuals (Channa & Gray 2009).

= Threats =

Key threats to yellow-cheeked crested gibbons within PPWS appear to be habitat loss and degradation caused by legal and illegal extractive activities, primarily gold mining and selective logging (Channa & Gray 2009). In addition, habitat degradation associated with gold mining includes harvesting of wood, for fuel in mineral processing and for the construction of stairs and supports for underground mines (Channa et al. 2009). Survey teams in 2008 recorded evidence of illegal logging and associated infrastructure in the reserve. Most loggers appeared to be from outside Mondulkiri, and targeted ''Afzelia xylocarpa'', a globally threatened and valuable tree species (Channa et al. 2009).
