* Western chimpanzees (''Pan troglodytes verus'') are no longer present in Atewa Range Forest Reserve.
* Chimpanzees have been extirpated from the site.
* The site has a total size of 258 km².
* Chimpanzees were mainly threatened by hunting.
* Conservation activities have focused on patrolling and controlling poaching.

Atewa Range Forest Reserve is located in southeastern Ghana. The reserve is on a mountain range, which peaks at 842 m a.s.l., (Kusimi 2015). Atewa is unique because of its Upland Evergreen forest, which is an important reservoir of biodiversity. It was established as a national forest reserve in 1926, a Special Biological Protection Area in 1994, a Hill Sanctuary in 1995, as one of Ghana’s 30 Globally Significant Biodiversity Areas (GSBAs) in 1999, and an Important Bird Area (IBA) by BirdLife International in 2001 (RAP 2007). In 2021, a new frog species was discovered in the site; it was given the common name Atewa Slippery frog, ''Conraua sagyimase'' ([https://ghana.arocha.org/projects/protecting-atewa-forest/ A Rocha Ghana]).

No chimpanzees have been found in the reserve. An old chief hunter reported that he has not seen a chimpanzee in the forest since he started hunting over 40 years ago (Ofori-Amanfo pers. comm. 2023). During a 2006 Rapid Assessment Program (RAP) survey of the site, most nearby communities said that chimpanzees were not present; this was in line with the RAP’s transect and recce survey results, which found no evidence of chimpanzees (McCullough et al. 2007).

= Threats = <!-- a text overview of threats, followed by a table of key threats -->
Chimpanzees were mainly threatened by the high levels of uncontrolled hunting (Ofori-Amanfo pers. comm. 2023). A study by Kusimi 2015 also found that land cover (especially forest cover) in the reserve declined, while land use increased between 1986 and 2013. Parts of the forest degraded into bushes/shrubs and the peripheral landscape was more affected due to intense human activities such as farming and illegal logging. Other activities such as expansion of settlements and illegal gold mining have also contributed to the negative impacts on the forest cover (Kusimi 2015). Atewa Forest is one of three possible sites where the government of Ghana is seeking to mine bauxite to develop an integrated bauxite-aluminium industry; up to this point it has not been exploited but the risk still exists (Purwins 2022).

|In June 2019, in the absence of an environmental impact assessment, the Ghanaian authorities started clearing access roads to Atewa Forest to allow test-drilling for bauxite ([https://www.iucncongress2020.org/motion/103 IUCN Congress 2020]). Bauxite deposits have been assessed several other times at the site by prospective companies, but bauxite mining has been so far met with strong opposition (Lindsell et al. 2019).
