Site description Situated in a fossil valley dating from the last ice-age or earlier, Dan Doutchi was, prior to July 1974, a small, temporary wetland surrounded by millet and sorghum fields. When, however, the 1973–1974 drought broke with torrential rains, this wide, shallow part of the valley filled to form a permanent wetland. The wetland, located some 80 km north-west of Birni N’Konni, extends from the village of Tawèy to that of Dan Doutchi, 6 km to the west and, at its maximum, occupies approximately 1,780 ha with an average depth of 1.8 m. Average annual rainfall in the Dan Doutchi area for the period 1961–1990 was 420 mm, but yearly variation is considerable. During the waterbird censuses in January–February, the area of the run-off dependent wetland accordingly varied from 450 to 1,500 ha. The water of the wetland is somewhat brackish and alkaline, with average levels of nitrogen and low levels of phosphorus in the fairly sandy sediment. Aquatic vegetation is absent. Woody species along the edges of the wetland include Acacia nilotica and the exotic Eucalyptus camaldulensis.
