The Adrar Bous is a 1123-metre-high mountain on the north-eastern edge of the Aïr high mountains in Niger. It is surrounded by the Ténéré desert and is part of the Aïr and Ténéré UNESCO World Heritage Nature Reserve. The mountain has an elliptical shape covering an area of 16 by 10 kilometres. The Adrar Bous is a refuge for Palaearctic migratory birds in the middle of the desert. Typical woody plants for the mountain are Acacia ehrenbergiana and Acacia raddiana (pictured). The isolated mountain was inhabited in the Neolithic period, as evidenced by sites with 10,000-year-old human remains. Arrowheads and tools have been found, as well as Sahara rock paintings, 9500-year-old pottery and a 6000-year-old cattle burial. - Niger - Aïr - 2003
