The Baie de Khnifiss is a complex system of interconnected habitats, including the Khnifiss lagoon, the sebkhas (salt flats) of Tazra and Mzeira, a large seasonal lake (daya La’wina), bordered by cliffs and steep sand dunes, the normally dry riverbed of Oued Awedri, and the adjacent marine coastline. Dune formations occasionally block water flow, making breaches rare. The lagoon is highly productive due to oceanic upwellings, supporting diverse flora and fauna, including the globally vulnerable marbled teal (Marmaronetta angustirostris). It also provides habitat for waterbirds such as the red knot (Calidris alba) and bar-tailed godwit (Limosa lapponica). The Site is a vital stopover for migratory birds along the East-Atlantic Flyway. Despite its ecological importance, habitat degradation and hydrological changes pose increasing threats. Strengthening conservation efforts is essential to preserving biodiversity and supporting migratory species.
