Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): The agricultural usage and drainage of this species' habitat are the main threats. Droughts are likely to affect the species, in addition to intrinsic factors such as its restricted range and limited dispersal.

Conservation Actions [top]

Conservation Actions: In France, the species is under regional protection (Rhones-Alpes and Ile-de-France). There are no other conservation measures in place except for research on taxonomy, habitat status, biology and ecology. More information on population numbers and range as well as habitat maintenance and conservation are needed.
