Marahoué National Park
Marahoué National Park

Marahoué National Park (IUCN category:II) was established in 1968. It covers an area of 101.000 ha and is located in the south-central parts of Côte d´Ivoire in the Bouafle region near Lake Kossou 275 km (170 miles) northwest of Abidjan (6°0'W 7°5'N). The Park contains two different ecological zones: close forest in the south-west and savannah in the north-eastern part. It is managed by the Office Ivoirien des Parcs et Réserves (OIPR).








Ape status

The chimpanzee (Pan troglodytes verus) population in Marahoué National Park was first estimated at 1407 individuals by Marchesi et al. (1995). Due to the relatively small sample size (number of transects) of this survey, this estimate should be regarded as a guess rather than an estimate of abundance. 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).

Threats

Poaching of chimpanzees and cocoa plantations are believed to have caused these dramatic declines in chimpanzee population size (Struhsaker and Bakarr 1999).

In addition, Marahoué National Park seems to have have 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). Agricultural encroachment (using fire to clear land) and illegal logging have resulted in the observed large-scale degradation of forest habitats in the country.

Surveys

In 2003 and 2004, surveys were conducted to assess the status of primate populations in three forest reserves including Marahoué National Park. Here, chimpanzee presence was inferred from interviews with local people (Sery, G.B. et al. 2006). In 2006 and 2007 - in addition to the biomonitoring activities in Taï National Park - the WCF (http://www.wildchimps.org) conducted two population surveys in Marahoué National Park.
