The Site is one of the largest remaining floodplain peatlands in the region, and supports plant communities which are particularly rare in Algeria, notably the narrow-leafed ash (Fraxinus angustifolia) and common alder (Alnus glutinosa). The wetland’s moderate acidity, richness of organic matter and water flows support a rich vegetation; about one third of the 120 plant species found are rare. The Site also hosts cattle egret, little egret, squacco heron and various forest passerines. It is an important area for research in ornithology, herpetology and botany. The Site is threatened by excessive water extraction for irrigation by the local community.
