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).

Based on two population surveys in 2005 (Kouakou et al. 2012) and 2014 (Kouakou et al. 2014), Kühl et al. (2017) estimated a stable chimpanzee population trend for this site.

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.

West Africa > Liberia > Grebo-Krahn National Park

Summary[edit]

Loading map...
  • Western chimpanzees (Pan troglodytes verus) are present in Grebo-Krahn National Park.
  • It has been estimated that 313 (CI: 186-449) individuals occur in the site.
  • The chimpanzee population trend is stable.
  • This site has a total size of 971 km².
  • Key threats to chimpanzees are poaching, illegal mining and farming activities.
  • Conservation activities, led primarily by the Wild Chimpanzee Foundation (WCF), have focused on law enforcement, awareness campaigns, and supporting sustainable small-scale aquaculture activities in local communities.

Site characteristics[edit]

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, several endangered species inhabit Grebo-Krahn National park, including Jentink’s duiker (Cephalophus jentinki), forest elephants (Loxodonta africana), pygmy hippos (Hexaprotodon liberiensis), and Diana monkeys (Cercopithecus diana diana, Kouakou et al. 2012, Barrie et al. 2007).

IUCN habitat categories Site designations

Ape status[edit]

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). Based on two population surveys in 2005 (Kouakou et al. 2012) and 2014 (Kouakou et al. 2014), Kühl et al. (2017) estimated a stable chimpanzee population trend for this site.

Threats[edit]

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).

IUCN Threats list

Conservation activities[edit]

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 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. In addition, the WCF is evaluating the feasibility of establishing a conservation corridor between Sapo National park and Grebo-Krahn National Park (WCF 2019).
