* Cestos-Senkwehn Proposed Protected Area forms part of an Important Bird Area (IBA). There are plans to link Cestos-Senkwehn Proposed Protected Area to Sapo National Park. The area falls into one of the conservation priority areas identified for Liberia by Junker et al. (2015). The latter was ranked highest of all patches in terms of chimpanzee density, and mammal and tree diversity and links up with Krahn Bassa National Forest.

Cestos-Senkwehn Proposed Protected Area lies in the lowly populated coastal centre of Liberia between the towns of Buchanan and Greenville and stretches inland from the coast for some 70 km. The area serves as host for wildlife transiting from Krahn-Bassa Proposed Protected Area and Sapo National Park. Cestos-Senkwehn Proposed Protected Area includes inland-, littoral-, and mangrove forests (Verschuren 1983). The site has also been classified as an IBA. In addition to chimpanzees, Tweh et al. (2014) found tracks of zebra- ''Cephalophus zebra'', Maxwell- ''Philantomba maxwellii'', and black duiker ''Cephalophus niger'' in this area during their nationwide survey. The endangered pygmy hippopotamus ''Choeropsis liberiensis'' has been reported for this site (Mallon et al. 2011), but could not be confirmed by Tweh et al. (2014) who surveyed two line transects in this area.

No published information could be found on wildlife surveys conducted in this area. Tweh et al. (2014) surveyed two line transects, each 3 km in length, and recces in Cestos-Senkwehn Proposed Protected Area during their nationwide survey and found 10 chimpanzee nests in three different groups (Junker unpubl. data).

The main threats to chimpanzees in this area include artisanal mining for gold and poaching. Tweh et al. (2014) found numerous empty cartridges and a few snares, as well as signs of artisanal gold mining. However, people who were interviewed in the villages in this area reported that there was a local taboo against killing chimpanzees in their area (Junker unpubl. data). The area has also been assigned to a mining company on a Mineral Exploration License (MEL) (Johnson et al. 2015). This license type entails that after a proposed exploration program has been handed to the Minister of Land, Mines, and Energy, the company commences exploration (Wilson et al. 2017).
