Site characteristics

This unprotected area is located in the Kedougou region, around 30 km from the Niokolo Koba National Park (PNNK) in south-eastern Senegal. Bantankiline is close to the village of Marougounding near the hamlet of Fongoli, home to the only group of chimpanzees in Senegal accustomed to human presence (Pruetz et al., 2008).

Ape status

Surveys have taken place in the site between July and October 2018 and between October 2020 and October 2021. During these surveys, a total of 809 chimpanzee nests were recorded while walking a total distance of 155.1 km distributed along 37 recce transects, which averaged 4.19 km per transect (Diallo et al. 2022).

Threats

Key indirect threats to chimpanzees in the area include deforestation linked to wood for carpentry and construction, consolidation of gold pits, charcoal production, transhumance. Artisanal gold panning is not yet very present in the area, but the risk of this process accelerating is high. Deforestation is currently very marked in Bantankiline. The main causes are charcoal production and the use of wood to consolidate gold pits, commonly known as "Diouras" in the local language. The trees are cut right down to the level of the forest galleries that form the heart of the chimpanzees' nesting sites. Diallo (2018) had counted and geolocated several tree trunks cut by loggers along the forest galleries of Bantankiline. We found that, in general, the plant species targeted by loggers are also very often used by chimpanzees for nesting. These are mainly Pterocarpus erinaceus, Khaya senegalensis, Anogeissus leiocarpus and Diospyros mespiliformis. These species are therefore important for chimpanzee-nesting in Senegal.
