Summary

Western chimpanzees (Pan troglodytes verus) are probably no longer present in Bong Mountain Proposed Protected Area.
This site has a total size of 248.12 km².
Key threat to chimpanzees is mining.
Conservation activities were not reported.
The area has been designated an International Bird Area (IBA) and been proposed for a Key Biodiversity Area (KBA) by the Critical Ecosystem Partnership Fund (CEPF).

Site characteristics

Bong Mountain Proposed Protected Area is located in Bong county in central Liberia. The area has partially been deforested, especially along the edges (Christie et al. 2007). The area has also been affected by mining of the China Union Project (Johnson 2015). Bong Mountain has a core of steep land with a narrow zone of closed dense forest, but also has existing roads, a moderate population density on the margins, and a potential for iron ore production (Johnson 2015). Johnson (2015) mentions in her report that the boundaries of the Bong Mountain Proposed Protected Area have been altered by the Forestry Development Authority in Liberia due to the mining operations that are/will be taking place in the area. Neither information on the altered geographical extent of this site, nor the flora and fauna in this area could be found.

Ape status

It is likely that chimpanzees have become extinct at this site, as the area around Bong Mountain Proposed Protected Area has been almost completely deforested (Christie et al. 2017, Junker pers. obs.) and because much of the site is currently being mined for iron ore (Johnson 2015). The nationwide chimpanzee abundance model published by Junker et al. (2015) suggests that chimpanzees are likely to be absent from this area. However, no chimpanzee surveys have been conducted at this site. Because the entire Bong Mountain Proposed Protected Area has been proclaimed a mining site (Johnson 2015), it will probably no longer be considered a protected area in the future.

Threats

The southern part (about one third of the total area) of Bong Mountain Proposed Protected Area has been sold to a mining company, namely China Union Mining Co. The commodity that is being mined is iron ore. The total area of the mining site is 610 km2 (Wilson et al. 2017). The license type is a Class A mining license, which entails that mining is permitted in the proposed production area (no size limit) for at least 25 years (Wilson et al. 2017). The remaining part of Bong Mountain Proposed Protected Area is under a Development Exploration License (DEL), which means that the license holder has to submit a proposed exploration program to the Minister of Land, Mines, and Energy within 90 days-, and shall commence exploration within 180 days after the issuance of an exploration license (Wilson et al. 2017). The company started production in early 2014 to June 2015, but later suspended operations in late 2015, as a result of the twin shock - Ebola virus disease in Liberia and the price of iron ore. The water in the area is heavily polluted, because of seepage of heavy metals from the iron ore mine into local creeks, wells and groundwater (Wilson et al. 2017).
