Zwedru Proposed Protected Area

West Africa > Liberia > Zwedru Proposed Protected Area

Summary

• Western chimpanzees (Pan troglodytes verus) are likely to be present in Zwedru Proposed Protected Area.
• The population size is unknown.
• The chimpanzee population trend is unknown.
• This site has a total size of 637.15 km².
• Key threats to chimpanzees are hunting, large-scale mining and commercial logging.
• Zwedru Proposed Protected Area has been designated a Key Biodiversity Area (KBA) and an International Bird Area (IBA).

Site characteristics

Zwedru Proposed Protected Area is located 20 km west of the town Zwedru – the capital of Grand Gedeh county - on the northern border between Liberia and Côte D’Ivoire. It has been designated an IBA and a KBA, because it is the only known site where the critically endangered Liberian greenbull, Phyllastrephus leucolepis, has been reported (Johnson 2015). No information about other surveys at this site could be found. During the nationwide survey in 2010-2012 (Tweh et al. 2014), the survey teams found fresh and old chimpanzee nests three kilometers from the border of Zwedru Proposed Protected Area, on the north-western boundary of the site (Junker unpubl. data).

Ape status

A survey of indicator species was undertaken in 2005 (FFI 2005). This was a collaborative effort of Fauna & Flora International (FFI) the FDA, Environmental Protection Agency of Liberia (EPA) and the Ministry of Planning and Economic Affairs (MPEA). However, no further details on this survey could be found.

Threats

The entire proposed protected area is covered by Mineral Exploration Licenses (MEL) for gold, diamonds and other minerals except for iron ore owned by Superior Mineral Resources Inc. (Johnson 2015). MEL’s entail 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). Zwedru Proposed Protected Area overlapped with illegally issued Private-Use Permit (PUP) for commercial logging. Private Use Permits were a type of logging licence designed to allow private land owners to cut trees on their property, but which were reportedly subject to misuse by commercial logging companies. After investigations by Global Witness (Global Witness 2013) much public outcry and extensive media coverage, PUPs have now largely been rescinded (Johnson 2015). Moderate amounts of hunting signs were also recorded on two line transects about 3 km south-west of Zwedru Proposed Protected Area (Junker unpubl. data).
