<!-- INSTRUCTIONS FOR COMPLETING SITE INFORMATION
 
−
- Wiki site pages contain information in paragraphs of text, tables, keyword lists, and images
 
−
- Text paragraphs and images are not restricted, so text format and images can be chosen as desired.
 
−
- Tables and keyword lists are extracted as data, and so have the following restrictions:
 
−
  1) Table structure cannot be changed
 
−
  2) Keyword format should not change, i.e. they are comma separated lists, not bullet points or numbered lists.
 
−
  3) Keywords must be taken from the list of permitted words, or added to the list of permitted keywords. A link to the keyword list page is found adjacent
 
−
    to the relevant table or keyword list. This ensures that the same keyword always refers to the same concept, e.g. Everybody uses "Industrial mining",
 
−
    rather than several keywords such as "Industrial mining", "Large-scale mining", and "Mining".

Located in southeastern Liberia, the site is part of the Tai-Grebo-Sapo Forest Complex, a biodiversity hotspot and conservation priority in West Africa (Kouakou et al. 2012).  In addition to the Western chimpanzee (Pan troglodytes verus), several endangered species inhabit Grebo-Krahn National park, including Jentink’s duiker (''Cephalophus jentinki''), forest elephants (''Loxodonta africana cyclotis''), pygmy hippos (''Hexaprotodon liberiensis''), and Diana monkeys (''Cercopithecus diana diana'') (Kouakou et al. 2012, Barrie et al. 2007).

In 2012, the Wild Chimpanzee Foundation (WCF) and the Forestry Development Authority (FDA) conducted the first complete survey of chimpanzees and other large mammals of the Grebo National Forest (Kouakou et al. 2012). The estimated abundance has remained relatively stable since then; the most recent survey estimated a total population of approximately 313 individuals in 2015 (Furnell et al. 2015).

Grebo-Krahn National Park is mainly threatened by illegal hunting, mining, and farming activities (WCF 2019). The park has also been highly threatened by chewing-stick (Garcinia spp.) harvesting, which developed into industrial-scale operations in some areas of the park (WCF 2017).

The WCF has invested much effort in conservation activities in the Tai-Grebo-Sapo Forest Complex, including Grebo-Krahn National Park. In 2018 WCF worked alongside two theatre companies to produce a plays aiming to sensitize the communities surrounding the park to issues of deforestation and wildlife protection (WCF 2019). The WCF also works together with Liberia’s Forestry Development Authority (FDA) to systematically survey the park and collect signs of large mammals, as well as hunting and habitat disturbance signs. Sustainable fish-farming has also been facilitated by the WCF to provide an alternative protein source to bushmeat.
