Gola Rainforest National Park

West Africa > Sierra Leone > Gola Rainforest National Park

Summary

• Western chimpanzees (Pan troglodytes verus) are present in Gola Rainforest National Park.
• It has been estimated that 270 (CI: 159-468) individuals occur at the site.
• The chimpanzee population trend is unknown.
• This site has a total size of 710 km².
• Key threats to chimpanzees are poaching and habitat destruction due to logging and shifting agriculture.
• A REDD+ project is being developed and implemented at the site with the support of the Royal Society for the Protection of Birds, which aims to ensure funds for the continuation of conservation work in park and improve the management of natural resources.

Site characteristics

The site consists of three forest blocks (Gola North, Central, and South) situated in southeast Sierra Leone, which are linked to Liberia’s Gola National Park, forming a transboundary peace park. The forests in Gola Rainforest National Park are a catchment for the Moro, Mahoi, Mano and Moa rivers, providing an important water source for nearby villages (Barca et al. 2018). The area forms part of the Upper Guinean forest ecosystem, a biodiversity hotspot with a large number of endemic species. Close to 1,000 plant species have been identified in Gola Rainforest National Park, half of which are endemic to the Upper Guinea forest ecosystem. In addition to the western chimpanzee (Pan troglodytes verus), other threatened species inhabit the area, including pygmy hippos (Choeropsis liberiensis), pangolins, red colobus (Piliocolobus badius), and Jentink’s duiker (Cephalophus jentinki). Gola Rainforest National Park is also classified as an Important Bird Area (BirdLife International 2019a) and has been included in the tentative list of World Heritage Sites.

Ape status

The chimpanzee population in Gola Rainforest National Park is estimated to be 270 individuals, which is equivalent to almost 5% of Sierra Leone’s estimated population (Brncic et al. 2010). The population trend is unknown.

Threats

Approximately 28% of Gola Forest has been subject to logging (Klop et al. 2008). Large-scale logging operations in Gola started in the 1960s and continued until the late 1980s (Klop et al. 2008). Forestry Industries Corporation (FIC) and the Sierra Leone Timber Industry and Plantation Company (Sileti) were the two main companies responsible for the exploitation of timber in Gola (Klop et al. 2008). The resulting impacts from these logging operations include an extensive road network in Gola North, and a large clearing in Gola East. During the 1991-2001 civil war in Sierra Leone, the Revolutionary United Front set up camps near Gola forest; however, a survey that compared wildlife abundances before and after the war found no evidence of serious negative impacts from the war (Lindsell et al. 2011). Current threats in the area include small-scale logging, bushmeat hunting, and shifting agriculture.

Conservation activities

A conservation program began in 1990 by the Forestry Division of the government of Sierra Leone and the Conservation Society for Sierra Leone (CSSL). Since then, the Royal Society for the Protection of Birds (RSPB) became a supporter of the conservation projects in Gola, and the site is part of RSPB’s Forests of Hope Programme. Conservation activities were interrupted by the civil war but resumed after the return of peace in 2002 (Lindsell et al. 2011). A REDD+ project is currently under development at the site. The project will use funds obtained from the sale of carbon credits to improve the management of the park, fund long-term conservation work, develop sustainable farming practices, and the establishment of a research station in the park. Gola Rainforest National Park also has its own conservation center, the Gola Rainforest Conservation Center (GRCC), which hosts visitors and researchers. The GRCC also offers capacity building and environmental education activities to the staff of the park, students, and local communities.

Research activities

Several surveys have been done at the site to monitor wildlife and estimate species abundances (e.g., Brncic et al. 2010, Klop et al. 2008, Davies et al. 2008), and the nest ecology of chimpanzees has also been studied at the site (Barca et al. 2018).
