The Site covers the entire lower valley of Assaqia Al Hamra; it consists of four large areas, including a swamp and an estuary. A sandy dam keeps the wetland particularly close to its natural character, as it helps to recharge the aquifer of the Foum El Wad. The Site plays an important role in the life cycle of Western Palearctic water birds, as a migratory stopover and wintering area. It hosts threatened water birds such as the marbled teal (Marmaronetta angustirostris) and the common pochard (Aythya ferina). The wetland hosts up to 25 or more species of water birds in all, which often number a few thousand individuals; their number approached 15,000 in 2014 and exceeded 20,000 wintering individuals in 2008. The Site includes the three main Ramsar wetland types (marine and coastal, inland and human-made) and provides a wide range of ecosystem services for nature and surrounding populations. In addition to its ornithological importance, the Site hosts scientific and educational activities as well as leisure and tourism. It does not have a management plan; however bird species are monitored.
