The Site lies at the northern edge of the Western Sahara where Oued Dr'a, Morocco’s largest Atlantic wadi, flows into the ocean. Draining vast areas of the Grand Atlas and Anti-Atlas Mountains, it forms a wide, steep-sided corridor with a sandy bottom. The channel meanders through small dunes covered with bushy vegetation before entering a steep valley bordered by high cliffs and opening into the coastal plateau. The Site also includes coastal waters, cliffs, and a sandy beach north of the wadi. It offers critical habitat for vulnerable species, including the houbara bustard (Chlamydotis undulata), Audouin’s gull (Ichthyaetus audouinii) and marbled teal (Marmaronetta angustirostris). Beyond its ecological value, the area supports local livelihoods through fishing and tourism. However, habitat degradation and human disturbance pose growing threats. Strengthening conservation measures is essential to preserving biodiversity and ensuring long-term sustainability.
