Summary

• Western chimpanzees (Pan troglodytes verus) are present in Western Area Peninsula National Park.
• It has been estimated that 55 (CI: 15-209) individuals occur at the site.
• The chimpanzee population trend is unknown.
• This site has a total size of 183.37 km².
• Key threats to chimpanzees include logging, farming, hunting, and human encroachment.
• Awareness raising and support for alternative livelihoods are the main conservation interventions that have been implemented at the site.

Site characteristics

The Western Area Peninsula National Park (WAPNP) is located in the Freetown peninsula, west of Sierra Leone (BirdLife International 2019). The site covers a narrow chain of hills, reaching up to 900 m, and holds the western-most remnant of Upper Guinea forest ecosystem (Brncic et al. 2010). With 314 bird species, including five species of global conservation concern (e.g., white-necked rockfowl Picathartes gymnocephalus), WAPNP was designated as an Important Bird Area (IBA) in 2001 (BirdLife International 2019). The site is also of high importance to the surrounding populations, as it protects the watershed of two dams, which supply water to Freetown and nearby settlements (Brncic et al. 2010; EPA 2017). In addition to the western chimpanzee, other vulnerable species inhabiting the area include Diana monkey (Cercopithecus diana), Jentink’s duiker (Cephalopus jentinki), and the endemic frog Cardioglossa aureole (BirdLife International 2019).

Ape status

Based on a line transect survey in 2010, there may be three chimpanzee communities in the area (Brncic et al. 2010). The size of the population was estimated at 55 individuals, which is the most recent population estimate currently available (Brncic et al. 2010).

Threats

The park is highly accessible to humans through trails (Brncic et al. 2010). Hunting is a key threat in the area, with several hunting camps and hunting signs present at the site (Brncic et al. 2010). In addition, multiple large-scale marijuana farms have been discovered in the park, as well as signs of logging and charcoal production (Brncic et al. 2010). Due to the urban expansion and close proximity to the capital, Freetown, WAPNP faces a lot of pressure, as the demands for fuelwood, farmland, and bushmeat continue to rise (Brncic et al. 2010, BirdLife International 2017). In 2017, following heavy rainfall, a mudslide in the area resulted in the deaths of hundreds of people; the mudslide has been linked to extensive deforestation and erosion of the soil (BirdLife International 2017).

Conservation activities

Sierra Leone’s Forestry Division and the Conservation Society of Sierra Leone are the main organizations responsible for the management of the site and the implementation of conservation activities. The EU funded an intervention to decelerate deforestation at the site, which was implemented by Welthungerhilfe (WHH) and the Environmental Forum for Action (ENFORAC) from 2009-2014 (EPA 2017). This intervention focused on awareness raising, especially among potential encroachers, and proving support to local people with alternative livelihood options (Hempel 2013). In 1995, the Tacugama Chimpanzee Sanctuary was established. The sanctuary rescues, rehabilitates and cares for orphaned chimpanzees. Since 2011, Tacugama works with rural communities as part of its Tacugama Community Outreach Programme to promote the sustainable use of natural resources, improve agricultural practices (seed distribution), promote alternative livelihoods (e.g., fruit tree planting, livestock farms, community woodlots), improve health and hygiene in rural communities to decrease the risk of disease transmission, and environmental education activities for rural communities and children to increase awareness of the need to protect chimpanzees (Tacugama Chimpanzee Sanctuary 2020). Tacugama also runs an eco-lodge with the proceeds going to its conservation programmes (Tacugama Chimpanzee Sanctuary 2020).
