Merja Sidi Boughaba is a coastal wetland featuring a permanent brackish and freshwater lagoon surrounded by emergent vegetation. It is fed by groundwater and separated from the Atlantic Ocean by a stabilised dune system covered with Mediterranean scrub. The site supports diverse aquatic life, including a rich phytoplankton and algal flora, and sustains traditional fishing practices. It is an important breeding and staging ground for waterbirds, including the globally near-threatened marbled teal (Marmaronetta angustirostris). The wetland also serves as a centre for conservation education through its eco-museum. However, it faces challenges such as habitat degradation and water pollution. Conservation efforts focus on maintaining its ecological integrity while maintaining sustainable use.
