Bia Conservation Area
Summary
- 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).

Ape status
Wildlife patrol team encounters with chimpanzee signs indicate a decreasing trend (Danquah, E., pers. comm. 2022).

Threats
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. Between February and September 2023, the park conducted a programme, with funding from the Africa Elephant Fund (AEF), in 11 human wildlife hotspot communities where wildlife (with emphasis on elephants) invade community farms and livelihoods resulting in human wildlife conflict situations sometimes resulting in reprisal killings of wildlife. These communities were sensitised and educated on ways to mitigate human wildlife conflicts. Community Volunteer Squads were then formed, trained and given implements and the necessary tools and education to prevent wildlife raids on farms which results in human wildlife conflicts (Quansah P. K., pers. comm. 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) | |

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 | |

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.
