West Africa > Liberia > Gola Forest National Park
Summary
- Western chimpanzees (Pan troglodytes verus) are present in Gola Forest National Park.
- It has been estimated that 94 (CI: 225-539) individuals occur in the site.
- The chimpanzee population trend is unknown.
- This site has a total size of 880 km².
- Key threats to chimpanzees are hunting and habitat disturbance due to illegal farming, logging and mining activities.
- BirdLife International, the Society for the Conservation of Nature in Liberia, and the Forestry Development Authority of Liberia worked together on the establishment of Gola Forest National Park; these are also the main organizations implementing conservation activities in the park.
- Gola Forest National Park is adjacent to the Gola Rainforest National Park in Sierra Leone, forming a transboundary peace park.
Site characteristics
Situated in northwest Liberia, the site was first classified as a National Forest in 1960 (Hoke et al. 2007), and designated as National Park in 2016 (Rainforest Trust 2018). The park is located in the Upper Guinea Forest of West Africa, a biodiversity hotspot with very high rates of endemism (Hoke et al. 2007). In addition to chimpanzees, other endangered mammal species inhabit the site, including Jentink’s duiker, forest elephant, pygmy hippopotamus, leopard, and bongo (Barrie et al. 2007). The site has also been declared an Important Bird Area (BirdLife International 2019). Gola Forest National Park is strategically connected to Sierra Leone’s Gola Rainforest National Park to establish a bi-national peace park (Rainforest Trust 2018).

Ape status
The most recent estimate of chimpanzee abundance was 94 individuals in the year 2012 (Tweh et al. 2014). Due to a lack of survey data, the population trend in unknown.

Threats
Several years of civil conflict in Liberia (1989-2003) led to the encroachment of Gola National Forest by displaced people and increased illegal mining and farming activities, as well as bushmeat hunting (Hoke et al. 2007). Illegal mining and logging activities were particularly aggravated by the civil wars (Hoke et al. 2007). Other major threats include bushmeat hunting and illegal farming activities (Hoke et al. 2007). Furthermore, since the end of the second civil war, the interest from international logging and mining companies to extract timber and mineral resources in the country was renewed (Tweh et al. 2014). In 2005, two mining companies were large-scale prospecting at Gola National Forest (Barrie et al. 2007).

Conservation activities
The site is part of BirdLife International´s (Forests of Hope program), which aims to restore natural forests and support their long-term management. BirdLife International is also carrying out (monitoring projects) in the site. As part of the (GolaMa Project), the Society for Conservation of Nature in Liberia (SCNL) works to manage and protect the surrounding parts of the Gola forest that are not protected.

Research activities
Jones et al. (2019) evaluated the effectiveness of conservation interventions (e.g., participation in livelihood-support programs) in villages adjacent to Gola Forest National Park. The responsiveness of two different target groups (hunting households and high-impact hunters) to the same conservation interventions differed. This implies that audience segmentation could improve the effectiveness of conservation interventions, by targeting specific groups (Jones et al. 2019).
