La Vallée d'Iherir. 02/02/01; Illizi; 6,500 ha; 25°24'N 008°25'E. Parc National du Tassili; UNESCO World Heritage site. A high valley (1100m-1400m) in the center of a limestone Saharan plateau characterized by intermittent streams, lakes, and marshes, freshwater springs, and subterranean karst hydrological systems. The isolated nature of the site has led to remarkable evolutionary phenomena, described as "at the same time, a laboratory and a museum of the process of evolution", particularly for species which have been best able to resist the desertification of the area, such as lizards, serpents, and four species of fish. Basic palm and fig culture is practiced near the site by the Tuareg community on terraces above the valley floor, and some raising of vegetables takes place in areas shaded by trees. The rocky mountain walls bear rich pictorial evidence of some of the first human inhabitants of the Sahara; this has encouraged fairly significant tourism, which, however, was drastically diminished between 1992 and 2000 and is only recently beginning to recover. Ramsar site no. 1057. Most recent RIS information: 2001.
