Site description Koumbé Niasso lies between the towns of Toguéré-Koumbé and Ténenkou on the western side of the Inner Delta of the Niger. It is situated to the east of the Diaka river, about 15 km south of Séri (site ML011). The site includes an area of seasonally flooded Acacia woodland surrounded by flooded grassland, seasonal agricultural land and permanent water-bodies in the deeper depressions. The site is defined as a circular area with a diameter of 10 km, centred on the woodland which, in 1986, was reported to be increasing in extent.

Key Biodiversity See Box for key species. There are two major heron breeding colonies, 1.5 km apart, included within this site. In both 1985 and 1986 these sites together held over 30,000 pairs of herons of 10 species.
