The Arbre du Ténéré from a distance! This tree was an umbrella thorn acacia (Acacia tortilis) that was considered the most isolated tree on earth - supposedly the only one within a radius of 400 kilometres, other data mention 150 km. It was probably the last surviving tree of a group of trees that grew up when the desert was less dry than at present. The tree stood alone for several decades. - Ténéré - Niger - 1966
