Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1

Bythiospeum articense is known from the Ardèche and Gard departments in France, and it is considered to be widespread in Gard (V. Prie, pers. comm, 2009). Although very localised, the low level of threats to the majority of sites suggests that the species should be listed as Least Concern, rather than Near Threatened (Vincent Prie, 2009, pers. comm).  However, should the level of threats to these sites change or should there be a decline in the number of sites where the species is known, then the species status should be reviewed, therefore, monitoring of habitat needs to be implemented.
