Threats [top]

Major Threat(s): Major threats include Alcoa titanium and dune mining, and sedimentation mainly occurring in the southern African region. Residential and recreational development (marina construction) in South Africa and aquaculture in Tanzania (Rufiji River delta), both of which lead to habitat destruction. In Mozambique, tractor harvesting for prawns is also destroying habitat.

Conservation Actions [top]

Conservation Actions: In southern Africa, ecological impact studies are required for all coastal developments affecting the environment.
