<!-- INSTRUCTIONS FOR UPLOADING SITE INFORMATION
- Wiki pages contain information in paragraphs, tables, lists, and images.
- Text and images are not restricted, and their formats can be chosen as desired.
- Tables and lists are extracted as data, so the following restrictions apply to them:
1) Table structure cannot be changed.
2) List format should not change, i.e. they are comma separated lists, not bullet points or numbered lists.
3) To make information comparable across wiki pages, keywords must be taken from the list of permitted words, or added to the list of permitted keywords. This is why we use official lists, e.g., IUCN classification lists, in our tables.

= Summary = <!-- An overview of the site, with one sentence for each section. May include a site map -->
* Eastern chimpanzees (''Pan troglodytes schweinfurthii'') are present in Bili-Uéré.
* It has been estimated that 313-984 individuals occur in the site.
* The chimpanzee population trend is stable.
* The site has a total size of 60,000 km².
* Key threats to chimpanzees are hunting, mining, and deforestation due to agricultural expansion.
* Conservation activities implemented at the site include forest patrols and a community conservation project.

The Bili-Uéré Domaine de Chasse is the largest protected area in DRC. Created in 1974 (République Démocratique du Congo Ministere des Travaux Publics et Infrastructures, 2007), it follows the border of the Central African Republic and covers a total area of 60,000 km² (Doumenge, 1990, cited from pers. comm. with Direction Générale IZCN, Kinshasa 1988). The domaine de chasse is made up of seven blocks, including the Mbomu Reserve. The region to the north of the Uele River is characterized by extensive areas of savanna and savanna woodland, mixed with islands of old-growth tropical moist forest. The savanna is interlaced with hundreds of small streams and rivers, many of which dry up in the dry season, and which harbor lush gallery forests. The savanna eco-type becomes progressively more predominant to the north towards the Mbomu River. The fauna is a mix of savanna species such as aardvark, warthogs, lions and bushbuck, together with forest species: forest buffalo, forest elephant, giant forest hog, land leopard. Nine species of non-human primate occur (Hicks 2010a).
