Threats [top]

Major Threat(s): The threats to the species are poorly understood, however its native steppe habitat is under threat from human encroachment. There has been a huge increase in buildings and infrastructure in the area for recreation purposes (Zabortseva and Yevstropieva 2009). It is not known if climate change poses a threat to this species, but the Baikal region has been highlighted as an area where global warming occurs at a faster rate and that ecosystems respond to this by aridization and desertification (Kulikov et al. 2014).

Conservation Actions [top]

Conservation Actions: The species is known to occur in Pribaikalskyi National Park.
