A system of seasonal watercourses and permanent pools in a long-inactive branch of the River Niger, associated with a 775-kilometre depression running southward from Mali. Sandy soils and a near-surface aquifer contribute to the agricultural importance of the area and enable the only viable West African giraffe population. The Site also supports numerous fish species at different stages of their life cycles; certain species migrate towards the River Niger during the winter season, enriching the biodiversity there. Chief human uses of the area include irrigation agriculture, livestock, forestry, fishing and the extraction of the salt-like natron. The area boasts dense woody vegetation characterized by Parinari macrophylla, Hyphaene thebaica and Acacia albida. The effects of desertification in the region give cause for concern, including uncertain rains, sand encroachment, and inadequate groundwater recharge, and overgrazing and soil impoverishment through over-cultivation are seen as potential threats. The area is adjacent to Park National du W and is part of the UNESCO Biosphere Reserve of that name.
