Farangbaia Forest Reserve (FFR) is located in the Kalansogoia chiefdom, in Sierra Leone’s Tonkolili district (Garriga 2014). Designated as a forest reserve, FFR encompasses hills ranging from 275 meters to 860 meters above sea level. It is positioned approximately 5 km southeast of Bumbuna town and constitutes a vital part of the Seli River's watershed. To the east, the Tonkolili River forms the boundary of FFR, eventually merging with the Seli River. The landscape within the study area exhibits a diverse composition, including agricultural land, fallow land with woody regrowth (known as 'farm-bush'), remnants of original forest cover, grasslands on hills, and pockets of riverine forest in adjacent valleys. Human activities, particularly shifting cultivation, have significantly altered the environment in this region (Garriga 2014). | Farangbaia Forest Reserve (FFR) is located in the Kalansogoia chiefdom, in Sierra Leone’s Tonkolili district ([[#R00554|Garriga 2014]]).

The natural habitat within the FFR has undergone significant degradation, characterized by sparse patches of secondary forest primarily found in riparian zones and areas of challenging terrain such as cliffs and steep hills (Garriga 2014). The predominant habitat types consist of cultivated farms and extensive farm-bush. Two small permanent human settlements, along with their cultivated fields, are situated on the southern side of the study area's hills. Human presence was documented in four instances, captured by cameras placed at two different locations during a 2013 survey. Notably, one individual was observed carrying a shotgun. The theft of one camera trap serves as additional evidence of human activity in the area under study. Numerous human trails, paths, and traps were identified throughout the study area, indicating regular use of the site by local residents for activities such as hunting, farming, and logging (Garriga 2014). | The natural habitat within the FFR has undergone significant degradation, characterized by sparse patches of secondary forest primarily found in riparian zones and areas of challenging terrain such as cliffs and steep hills ([[#R00554|Garriga 2014]]).

Summary
- Western chimpanzees (Pan troglodytes verus) are present in Farangbaia Forest Reserve.
- The population size is unknown.
- The chimpanzee population trend is unknown.
- The site has a total size of 12 km².
- Key threats to chimpanzees are conversion of forest to agricultural land and hunting.
- Conservation activities are not documented.
Site characteristics
Farangbaia Forest Reserve (FFR) is located in the Kalansogoia chiefdom, in Sierra Leone’s Tonkolili district (Garriga 2014). Designated as a forest reserve, FFR encompasses hills ranging from 275 meters to 860 meters above sea level. It is positioned approximately 5 km southeast of Bumbuna town and constitutes a vital part of the Seli River's watershed. To the east, the Tonkolili River forms the boundary of FFR, eventually merging with the Seli River. The landscape within the study area exhibits a diverse composition, including agricultural land, fallow land with woody regrowth (known as 'farm-bush'), remnants of original forest cover, grasslands on hills, and pockets of riverine forest in adjacent valleys. Human activities, particularly shifting cultivation, have significantly altered the environment in this region (Garriga 2014).

In 2013, a camera trap survey was conducted in the FFR and an adjacent area to the east of the reserve (Garriga 2014). The survey effort was 1505 trap days in 28 locations. The trap nights of effort (subtracting days when the cameras stopped working) was 1385 trap days. The cameras did not capture any chimpanzees, but the field team recorded evidence of their presence in several locations (nests and feeding signs). It was concluded that there are chimpanzees living in the FFR and the adjacent study area, or that the reserve is part of a larger territory (Garriga 2014).

Threats
The natural habitat within the FFR has undergone significant degradation, characterized by sparse patches of secondary forest primarily found in riparian zones and areas of challenging terrain such as cliffs and steep hills (Garriga 2014). The predominant habitat types consist of cultivated farms and extensive farm-bush. Two small permanent human settlements, along with their cultivated fields, are situated on the southern side of the study area's hills. Human presence was documented in four instances, captured by cameras placed at two different locations during a 2013 survey. Notably, one individual was observed carrying a shotgun. The theft of one camera trap serves as additional evidence of human activity in the area under study. Numerous human trails, paths, and traps were identified throughout the study area, indicating regular use of the site by local residents for activities such as hunting, farming, and logging (Garriga 2014).

Conservation activities
African Minerals (AML) has worked with the Forestry Division of the Ministry of Agriculture, Forestry and Food Security (MAFFS) to potentially modify and extend the boundaries of the Farangbaia Forest Reserve (FFR) adjacent to the AML mining operations in the Tonkolili District (Garriga 2014). This extension would act as an offset to enhance habitat and increase its protection for wildlife in the surroundings of the mine site. A 2013 camera trap survey recommended that the boundaries of the reserve should be expanded to cover the adjacent mountainous habitat within the study area, and its protection status should be upgraded to a non-hunting reserve. This would enable the implementation of protection measures like the banning of hunting and farming inside the reserve, thereby facilitating the recovery of the FFR in the medium and long term (Garriga 2014).
