Halfway back to Agadez from Ténéré, there was a celebrated isolated tree called L'Arbre du Ténéré. It was killed in a car crash and its remains are now in a museum in Niamey. This is a monument put up in its place. The guidebooks go on about how there isn't another tree for a hundred and fifty miles; this isn't so, there are scattered trees abutting the southern part of the Aïr massif, but they are quickly being cut down for firewood.
