Distribution in Bulgaria. Rila Mts (Suhoto Ezero lake); 1500–2200 m alt.
General distribution. Bulgaria.
Threats. Deterioration of habitat as a result of the climate aridisation; limited distribution; low density of the population, diminishing of the number of individuals due to active tourism in the area of distribution.
Conservation measures taken. Protected species according to the national Biodiversity Act. The population is within the borders of Rilski Manastir Nature park as well as in a site of the European ecological network Natura 2000 in Bulgaria.
Conservation measures needed. Investigations into the numerical strength and area of distribution, and monitoring of the population status in order to optimise the conservation measures implemented.
