Marahoué National Park (IUCN category: II) was established in 1968 (UNEP-WCMC and IUCN 2019). It covers an area of 1010 km2 and is located in the central Côte d´Ivoire in the Bouafle region near Lake Kossou. Marahoué NP is 275 km (170 miles) northwest of Abidjan. Marahoué NP is managed by the Office Ivoirien des Parcs et Réserves (OIPR). The park consists of two ecological zones: close forest in the south-west of the park and savanna in the north-eastern part. In a survey in 2007 signs of different mammal and bird species were found, including forest elephant (''Loxodonta africana''), pygmy hippopotamus (''Choeropsis liberiensis''), African buffalo (''Syncerus caffer''), and bushbuck (''Tragelaphus scriptus''). However, the park is strongly affected by illegal activities, especially forest clearing for cocoa plantations and poaching, and the current status of the biodiversity is unknown (Campbell et al. 2008, N’Goran et al. 2006, N’Goran et al. 2007, WCF 2012). | Marahoué National Park (IUCN category: II) was established in 1968 (UNEP-WCMC and IUCN 2019).

The chimpanzee (''Pan troglodytes verus'') population in Marahoué National Park was first estimated at 1407 individuals by Marchesi et al. (1995). However, due to the relatively small number of transects surveyed, large uncertainties are associated with this estimate. In 2007, a survey that covered 167.5 km of systematically located transects across the entire park yielded a conservative population estimate of fewer than 50 individuals (N´Goran et al. 2007). In 2012, a rapid assessment was conducted by the Wild Chimpanzee Foundation [https://www.wildchimps.org WCF] in collaboration with Afrique Nature, and no signs of chimpanzees were found. | The chimpanzee (''Pan troglodytes verus'') population in Marahoué National Park was first estimated at 1407 individuals by Marchesi et al.

Marahoué National Park has lost 93% of its forest cover between 2002 and 2008, which may be directly linked to the civil unrest prevailing in the country since 2002 (Campbell et al. 2008).

West Africa > Côte d’Ivoire > Marahoué National Park
Summary
- Western chimpanzees (Pan troglodytes verus) are now extirpated in Marahoué National Park.
- This site has a total size of 1,010 km².
- Chimpanzees are extirpated due to hunting and large-scale deforestation driven by the expansion of agricultural areas.
Site characteristics
Marahoué National Park (IUCN category: II) was established in 1968 (UNEP-WCMC and IUCN 2019). It covers an area of 1010 km2 and is located in the central Côte d´Ivoire in the Bouafle region near Lake Kossou. Marahoué NP is 275 km (170 miles) northwest of Abidjan. Marahoué NP is managed by the Office Ivoirien des Parcs et Réserves (OIPR). The park consists of two ecological zones: close forest in the south-west of the park and savanna in the north-eastern part. In a survey in 2007 signs of different mammal and bird species were found, including forest elephant (Loxodonta africana), pygmy hippopotamus (Choeropsis liberiensis), African buffalo (Syncerus caffer), and bushbuck (Tragelaphus scriptus). However, the park is strongly affected by illegal activities, especially forest clearing for cocoa plantations and poaching, and the current status of the biodiversity is unknown (Campbell et al. 2008, N’Goran et al. 2006, N’Goran et al. 2007, WCF 2012).

Ape status
The chimpanzee (Pan troglodytes verus) population in Marahoué National Park was first estimated at 1407 individuals by Marchesi et al. (1995). However, due to the relatively small number of transects surveyed, large uncertainties are associated with this estimate. In 2007, a survey that covered 167.5 km of systematically located transects across the entire park yielded a conservative population estimate of fewer than 50 individuals (N´Goran et al. 2007). In 2012, a rapid assessment was conducted by the Wild Chimpanzee Foundation WCF in collaboration with Afrique Nature, and no signs of chimpanzees were found.

Threats
Marahoué National Park has lost 93% of its forest cover between 2002 and 2008, which may be directly linked to the civil unrest prevailing in the country since 2002 (Campbell et al. 2008). Deforestation was many driven clearing land for agriculture using fires, especially for cocoa plantations, and illegal logging (Campbell et al. 2008, N’Goran et al. 2006, N’Goran et al. 2007, WCF 2012). In addition, the presence of people in the park and illegal hunting of chimpanzees likely caused the extinction of chimpanzees in Marahoué NP (Struhsaker and Bakarr 1999, Denis 2015).

Challenges
Denis (2015) conducted a comprehensive study into why Marahoué National Park degraded. The study was based on interviews with different stakeholders in Marahoué National Park and pointed out that already since its creation in 1968 farmers were present in the park and in 1990 13% of the park was occupied by people, and this percentage has grown steadily since (Denis 2015). Government support for maintaining the protective status of Marahoué was weak and inconsistent. There is also widespread corruption and a lack of technical means as well as human resources to ensure law enforcement (Denis 2015).

| Lack of government support | Denis 2015 |
| Lack of human resources | Denis 2015 |
| Lack of law enforcement | Denis 2015 |

As chimpanzees are extirpated from Marahoué National Park no research is conducted on chimpanzees.
