The Complexe du bas Tahaddart is a vast wetland complex on the Atlantic slope of the Tingitane Peninsula. The Site receives water from tidal flows and rainfall, with its hydrology heavily influenced by the Ibn Battota and Al Hachef reservoirs. The landscape is characterized by three primary habitat types: coastal marine waters, estuaries, and inland open waters and marshes. The Site is a vital habitat for various waterbirds, including the Eurasian wigeon (Anas penelope), the collared plover (Charadrius alexandrinus), the greater flamingo (Phoenicopterus roseus) and the endangered great bustard (Otis tarda). It also delivers critical ecosystem services, such as supplying drinking water to local communities and providing water for agriculture and livestock. The site is also used for recreational activities such as hunting and fishing, holds cultural heritage value and supports scientific research.
