Threats [top]

Major Threat(s): In northern Africa, dams, water pollution (agriculture, domestic and commercial/industrial), groundwater extraction and drought pose possible threats.

Conservation Actions [top]

Conservation Actions: None known. More research is needed into this species population numbers and range, biology and ecology, habitat status and threats, as well as monitoring and potential conservation measures.
