|Biosphere Reserve Information|
The Massif of Nimba is situated on the border between Guinea, Liberia and Côte d’Ivoire. Mount Nimba is part of the ‘Guinean Backbone’, rising 1,752 meters above sea level and representing a vast watershed with a great topographical diversity. Habitats are also very varying, including high altitude grassland, plain savanna with numerous herbaceous plant communities, primary forests located mainly on the foothills and in the valleys, drier mid-altitude forests as well as gallery forests. The area contains a rich endemic flora (including Blaeria nimbana and Dolichos nimbaensis) and fauna. Among the noteworthy animals is the viviparous toad Nectophrynoides occidentalis, which occurs in mountain grasslands and is the world’s only known tail-less amphibian that is totally viviparous. Mount Nimba was designated as a biosphere reserve and World Heritage Site in 1981.
There has probably never been any village on the actual mountains. However, there are ten villages in the immediate vicinity of Nimba with several thousand inhabitants, whose main economic activity is agriculture. Since 1991, population pressure has been increasing since many refugees have settled in the area. In response to this and the impact of an iron-ore mining, the Guinean government has established a management body (Centre de Gestion de l’Environnement des Monts Nimba), responsible for all environmental and legal questions, for the monitoring of water quality, for integrated rural development and for socio-economic studies. Since 1954, the Environmental Research Institute at Bossou (IREB) and the Nimba Scientific Station at Ziela carry out scientific surveys in the area. Studies on the Bossou Chimpanzee are undertaken by students and researchers from Guinea’s universities and the Primate Research Institute of Kyoto University (Japan).
