The site is located in southwestern Ghana, nearing the border with Côte d’Ivoire. The Bia Resource Reserve (228 km²) lies to the south of the national park (Dowsett-Lemaire & Dowsett 2011). Together, the national park and the resource reserve form a contiguous forest block that was originally established as a national park in 1974 (Dowsett-Lemaire & Dowsett 2011). However, the area now comprising the resource reserve was de-gazetted in 1977 and selectively logged for several years (Dowsett-Lemaire & Dowsett 2011). In 1983, Bia National Park was designated as a UNESCO Biosphere Reserve (UNEP-WCMC and IUCN 2019). Sixty-two mammal species have been recorded in the site, including 10 primate species (e.g., red colobus ''Procolobus badius'', black and white colobus ''Colobus vellerosus'', and olive colobus, ''Procolobus verus'') (Forestry Comission of Ghana 2019, Danquah et al. 2012).

West Africa > Ghana > Bia National Park
Summary
- Western chimpanzees (Pan troglodytes verus) may be present in Bia National Park.
- The population size is unknown.
- The chimpanzee population trend is unknown.
- This site has a total size of 78 km².
- Key threats to chimpanzees are poaching and logging.
- Conservation activities at the site focus on law enforcement.
- The site is a UNESCO Biospshere Reserve.
Site characteristics
The site is located in southwestern Ghana, nearing the border with Côte d’Ivoire. The Bia Resource Reserve (228 km²) lies to the south of the national park (Dowsett-Lemaire & Dowsett 2011). Together, the national park and the resource reserve form a contiguous forest block that was originally established as a national park in 1974 (Dowsett-Lemaire & Dowsett 2011). However, the area now comprising the resource reserve was de-gazetted in 1977 and selectively logged for several years (Dowsett-Lemaire & Dowsett 2011). In 1983, Bia National Park was designated as a UNESCO Biosphere Reserve (UNEP-WCMC and IUCN 2019). Sixty-two mammal species have been recorded in the site, including 10 primate species (e.g., red colobus Procolobus badius, black and white colobus Colobus vellerosus, and olive colobus, Procolobus verus) (Forestry Comission of Ghana 2019, Danquah et al. 2012). Forest elephants (Loxodonta cyclotis) and bongos (Tragelaphus euryceros) are also present (Forestry Comission of Ghana 2019).

Ape status
The presence of chimpanzees in Ghana is restricted to the forests in the southwestern part of the country (Kormos et al. 2003). Chimpanzees are thought to be present in Bia National Park, but the most recent survey only found traces of chimpanzees in the Bia Resource Reserve (Danquah et al. 2012). As part of the PanAf data collection, a survey was conducted at the site, but chimpanzee abundance and density are not published (PanAf 2019).

Threats
Illegal logging until the late 90s caused severe degradation at the site, and the construction of logging trails and roads facilitated human access into the area (Dowsett-Lemaire & Dowsett 2011). Uncontrolled hunting has been a big problem at Bia National Park and surrounding areas; the park faces a lot of human pressure, as it is completely surrounded by farmland (Dowsett-Lemaire & Dowsett 2011, Danquah et al. 2012).
Table 3. Threats to great apes in Bia National Park
| Category | Specific threats | Threat level | Quantified severity | Description | Year of threat |
|---|---|---|---|---|---|
| 1. Residential & commercial development | Not reported | ||||
| 2. Agriculture & aquaculture | 2.1 Annual & perennial non-timber crops | Present | The park is surrounded by farmland, and encroachment for agricultural expansion is a threat (Dowsett-Lemaire & Dowsett 2011) | Ongoing (2011) | |
| 3. Energy production & mining | Not reported | ||||
| 4. Transportation & service corridors | 4.1 Roads & railroads | Present | Logging trails and roads (Dowsett-Lemaire & Dowsett 2011) | Ongoing (2011) | |
| 5. Biological resource use | 5.1 Hunting & collecting terrestrial animals | High | Encounter rate of hunting signs: 0.40 km-1 (Danquah et al. 2012). A 2006-2008 survey reported 0.332 hunting signs per km (Gatti 2010) | Snares were found in the park during a survey, and hunting signs were also present in nearby sites (Danquah et al. 2012). | Ongoing (2012) |
| 6. Human intrusions & disturbance | Not reported | ||||
| 7. Natural system modifications | Not reported | ||||
| 8. Invasive & other problematic species, genes, diseases | Unknown | ||||
| 9. Pollution | Absent | ||||
| 10. Geological Events | Absent | ||||
| 11. Climate change & severe weather | Unknown | ||||
| 12. Other options | Absent |
Conservation activities
Wildlife protection at the site is enforced by the Ghana Wildlife Division (Danquah & Oppong 2013). Compared other sites in the Goaso forest block, a study found poaching rates to be much lower in the Bia National Park and Resource Reserve between 2007 and 2009 (AfriMAB 2013). This is likely attributed to the higher protection status of the area, and the implementation of conservation-oriented projects, such as the Protected Areas Development Programme Phase II (PADP II) in 2009, funded by the European Union, under which law enforcement and monitoring were increased (AfriMAB 2013).
