|Biosphere Reserve Information|
This biosphere reserve is located in the south-eastern part of the Algerian Sahara close to the borders to Niger and Libya. The Tassili plateau (1,500 to 1,800 meters above sea level), forms part of the Ordovician and Devonian sandstone layer surrounding the Precambrian crystalline massif of the Hoggar. The plateau is hyper-arid, but there are sub-arid microclimates suitable for the survival of relict Mediterranean fauna and flora. The most notable tree species is the cypress 'tarout' Cupressus dupreziana, wild olive Olea laperrini and myrtle Myrtus nivellei.
The site also hosts a rich inventory of fauna and archaeological, historical, cultural and geologic features - the reason for its designation as national park and world heritage site. Ancient cave paintings and rock engravings of large fauna such as hippopotamus and buffalo are of international importance.
The total population of the plateau was approximately 1,000 to 3,000 in 1986. The area is very sparsely inhabited by sedentary and nomadic Tuaregs who are living from stock rising and agriculture. Tourism has become an important source of income for the local population. However litter and the destruction of archaeological artefacts pose problems to the area.
