Summary
- Western chimpanzees (Pan troglodytes verus) are present in Pic de Fon Classified Forest.
- It has been estimated that 75 (CI: 21-246) individuals occur in the forest.
- The chimpanzee population trend is unknown.
- This site has a total size of 256 km².
- Key threats to chimpanzees are hunting and habitat degradation due to agricultural activities and fires, as well as exploration for mining.
- To mitigate negative impacts by proposed mining activities a conservation action plan was written in 2010 but it is unclear which activities were implemented.
- Due to its diverse habitat types Pic de Fon is very rich in biodiversity.
Site characteristics
Pic de Fon Classified Forest is located in southern Guinea at the southern end of the Simandou range and is part of the Greater Nimba Highlands. It has a size of 256 km² and was designated a classified forest in 1953 (UNEP-WCMC & IUCN 2019). The altitude of Pic de Fon ranges from 600 to 1,656 m and is the second highest mountain in Guinea (McCullough 2004). As it lies at the transition between forest and savanna zones it features a diversity of habitats including montane grassland and forest (gallery and ravine forests), semi-evergreen lowland forest (primary and secondary), savanna, rivers, and anthropogenic habitat such as plantations (coffee, cocoa, banana), and farmbush (McCullough 2004). This diversity of habitats leads to a diversity of plant and animal species which were surveyed in a rapid biological assessment in 2002. In this assessment 409 plant, 32 amphibian, 12 reptile, 233 bird, 21 bat, 40 katydid (bush crikets), 17 small mammal, 13 primate and 39 large mammal species were recorded, including species new to science and endemic species (McCullough 2004). Regarding primates the following primate species were recorded: western chimpanzee (Pan troglodytes verus), potto (Perodicticus potto), Demidoff ’s galago (Galagoides demidoff), sooty mangabey (Cercocebus atys atys), Campbell’s guenon (Cercopithecus campbelli campbelli), lesser spot-nosed guenon (Cercopithecus petaurista buettikoferi), greater spot-nosed guenon (Cercopithecus nicitans), Diana monkey (Cercopithecus diana diana, Herbinger & Tounkara 2004). In a conservation priority setting workshop in 2001, Pic de Fon was identified as having important habitat types for amphibians and reptiles (Bakarr et al. 2001). To inform the extension of the protected area network Brugière and Kormos (2009) identified 16 Key Biodiversity Areas across Guinea based on the occurrence of globally threatened large and medium-sized mammals, among which Pic de Fon Classified Forest ranked eight.

Ape status
Rebecca Kormos confirmed the presence of chimpanzees in Pic de Fon based on interviews with hunters (Ham 1998). As part of a rapid biological assessment line transect surveys were conducted by Herbinger and Tounkara (2004) and they estimated the size of the chimpanzee population at around 75 weaned individuals. In 2007 a further survey was implemented as part of the Simandou mining project that estimated the chimpanzee population at between 36-46 individuals, but details are not publicly available (Kormos et al. 2014).

Threats
A rapid biological assessment in 2002 identified 24 villages in the vicinity of Pic de Fon Classified Forest and concluded that villagers rely strongly on the forest as a source of food (e.g., wildlife, fish, fruits), water, wood for fuel and construction, and medicinal plants (McCullough 2004). Hunting was identified as the biggest threat to chimpanzees and wildlife in general (McCullough 2004). Hunting camps were also found inside the classified forest. 35-40% of the forest are impacted by the cultivation of subsistence and cash crops, including coffee (McCullough 2004). Fires are set intentionally to clear land for agriculture.

Conservation activities
One outcome of the rapid biological assessment conducted as part of an alliance between Conservation International and Rio Tinto Mining & Exploration in 2002, was an initial biodiversity action plan for Pic de Fon Classified Forest (McCullough 2004). The conservation objectives set out in this plan focus on biodiversity data and monitoring, regulating resource-use, awareness and capacity building, and strengthening the legal protection of the forest (McCullough 2004). However, it is not clear whether any of these activities have been implemented.

Challenges
The lack of capacity among regional actors, including government agencies, local communities and NGOs has been noted as an impediment, for example to implement law enforcement (McCullough 2004). Civil unrest, and conflict on land tenure were also mentioned as conservation impediments (McCullough 2004).
