• Western chimpanzees (Pan troglodytes verus) are present in the Bia Conservation Area.
• The population size is estimated at 34 weaned individuals.
• The chimpanzee population trend is decreasing.
• The site has a total size of 306 km².
• Illegal hunting is the main threat.
• Conservation activities have focused on anti-poaching patrols.

Site characteristics

The Bia Conservation Area (BCA) forms a 306km2 block in the moist evergreen and moist semi-deciduous forest zones of western Ghana, between the Bia River and the border with Côte d’Ivoire. BCA encompasses Bia National Park and Bia Resource Reserve; Bia National Park is 78 km2 and Bia Resource Reserve is 228 km2. The BCA was originally part of a larger (about 1500km2) ecosystem for forest elephants known as the Bia Group of Forest Reserves. However, the Bia elephant range has reduced over time due to clearance for cocoa cultivation, and is now an isolated population in an ecological island of forest with hard boundaries and no transitional zone to farmland (PADP 2001). It is planned for the entire area to be upgraded to national park status (Quansah P. K., pers. comm. 2023).

Threats

Bia National Park headquarters © Papa Kwaw Quansah

A total of 3,721 illegal human signs which are threats to the subspecies were recorded in 2021 and provided an overall encounter rate of 5.69 human signs per a kilometre walk. Three major threats among these were cartridge case (45.9%), wire snare (29.4%) and illegal logging (14.2%) (Danquah, E., pers. comm. 2022). Poachers still hunt in the park and set snares that also affect chimpanzees. Although poaching is not very frequent, it is a main threat because of the site’s low chimpanzee population abundance. Farm raids by wildlife resulting in human-wildlife conflict with elephants the most but chimpanzees are also involved. And with chimpanzees being low in numbers compared to elephants, it means a major threat to the chimpanzee population (Quansah P. K., pers. comm. 2023).

Conservation activities

Bia Conservation Area is a protected area so there are dedicated staff who patrol inside the Park to protect the resources including the chimpanzees. There is also a community outreach team that goes to the communities to educate them about the need to conserve natural resources including the chimpanzees. Ghana's Wildlife Division is responsible for maintaining law and order within the protected area.

1. Residential & commercial development	Not reported
2. Agriculture & aquaculture	Not reported
3. Energy production & mining	Not reported
4. Transportation & service corridors	Not reported
5. Biological resource use	5.6. Conduct regular anti-poaching patrols	Wildlife patrol teams regularly conduct law enforcement duties within and around the protected area (Danquah, E., 2022). Anti-poaching operations (day, night and long patrols) (Ofori-Amanfo pers. obs. 2023).	Ongoing (2023)
6. Human intrusion & disturbance	Not reported
7. Natural system modifications	Not reported
8. Invasive & other problematic species, genes, diseases	Not reported
9. Pollution	Not reported
10. Education & Awareness	10.1. Educate local communities about primates and sustainable use	Conservation education and outreach programmes in communities around the Park (Ofori-Amanfo pers. obs. 2023).	Ongoing (2023)
	10.2. Involve local community in primate research and conservation management	Communities around the park are aggregated into 10 Community Resource Management Areas (CREMAs) where they have a constitution and management plans backed by the local government to regulate the use of their natural resources and also help protect the protected area from human entering (Quansah P. K., pers. comm. 2023).	Ongoing (2023)
11. Habitat Protection	11.2. Legally protect primate habitat		Ongoing (2023)
	11.6. Demarcate and enforce boundaries of protected areas	Fifty (50) missing, broken and defaced boundary pillars replaced (out of a total of 115 boundary pillar points identified) to properly demarcate and delineate the park from fringe farms and prevent encroachment into the park (Quansah P. K., pers. comm. 2023).	2020
	Other	Enrichment planting has been carried out with some different kinds of indigenous tree species in some degraded portions of the Resource Reserve. The entire Bia Conservation Area boundary has been planted with indigenous tree species to prevent encroachment into the Park (Ofori-Amanfo pers. obs. 2023, Quansah P. K., pers. comm. 2023).	2018-2022
12. Species Management	Not reported
13. Livelihood; Economic & Other Incentives	13.2. Provide non-monetary benefits to local communities for sustainably managing their forest and its wildlife (e.g. better education, infrastructure development)	Tropenbus Ghana, UNESCO, and SNV Ghana support income generating activities such as beekeeping and honey processing, palm oil processing, soap production, snail farming, and mushroom cultivation (Quansah P. K., pers. comm. 2023).	Ongoing (2023)

Challenges

The Ghana Wildlife Division has few staff and resources to conduct effective and regular anti-poaching activities within and around the protected area. Inadequate staff, field equipment, vehicles etc. hinder effective protection of the chimpanzees.
