West Africa > Sierra Leone > Outamba-Kilimi National Park
Summary
- Western chimpanzees (Pan troglodytes verus) are present in Outamba-Kilimi National Park.
- It has been estimated that 1,020 (CI: 658-1,596) individuals occur in the site.
- The chimpanzee population trend is unknown.
- This site has a total size of 1,109 km².
- Key threats to chimpanzees are poaching, and habitat disturbance due to logging, cattle farming, and human settlements in the park.
- Conservation activities at the site mainly focus on providing sustainable livelihoods, but the progress and status of these projects are unknown.
Site characteristics
Situated in the north of Sierra Leone, Outamba-Kilimi National Park is divided into two blocks: Outamba (741 km2) and Kilimi (368 km2) (BirdLife International 2019). In the 1980s, with support from the IUCN and WWF, Geza Teleki, a primatologist and conservationist, was a driving force behind the establishment of Outamba-Kilimi National Park, which was finally declared as such in 1995 Brncic et al. 2010, Munro 2015). In addition to the western chimpanzee, the site is home to forest elephants (Loxodonta cyclotis), Western red colobus monkeys (Piliocolobus badius), pygmy hippopotamus (Choeropsis liberiensis), leopards (Panthera pardus), and forest buffalos (Brncic et al. 2010). With at least 256 bird species, the site is also an Important Bird Area (BirdLife International 2019).

Ape status
The population size was estimated at 1,020 chimpanzees during a nationwide survey in 2010 (Brncic et al. 2010). Due to a lack of survey data, the population trend is unknown. Chimpanzee densities are higher in Outamba than in Kilimi (Brncic et al. 2010).

Threats
The export and trade of wild animals, especially chimpanzees, emerged as a lucrative enterprise in Sierra Leone in the 1920s (Munro 2015). Two prominent wildlife dealers, Franz Sitter and Suleiman Mansaray, exported approximately 2,000 chimpanzees in the 1970s alone (Munro 2015). After Outamba and Kilimi were proposed as game reserves in 1965, Franz Sitter intensified hunting to take as much wildlife as possible from these areas before they could be protected (Brncic et al. 2010). Hunting signs are still present in both Outamba and Kilimi, indicating that poaching is an ongoing threat (Brncic et al. 2010). Many villages are found within the park, especially throughout the Kilimi section of the park, where cattle grazing, farming, and timber extraction also occur (Brncic et al. 2010). In the Outamba section, larger areas seem to be unaffected by humans than in Kilimi (Brncic et al. 2010).

Conservation activities
The site is a priority zone for the (STEWARD program), which is a forest conservation and sustainable livelihoods program supported by the United States Agency for International Development (USAID) and the United States Forest Service / International Programs (USFS/IP) (WCF 2015). The (https://panverus.org/about/ Pan Verus Project]) also aims to address the needs of local communities and find ways to provide sustainable agriculture practices and alternative livelihoods, for example, through tourism. More information on conservation projects is lacking for this site.
