Population size and its trends. At present, only small groups of these bats (3–15 individuals) can be found in the vicinities of Yerevan (Karmir Blur, Jrvezh) and upstream the Hrazdan River to the Meghradzor village, Kotayk Province. The population experiences a strong decline, with only singular individuals surviving in some sites (Karmir Blur, Magili, Chaikend).

Major threats. Human visitations to caves during the breeding, rearing and wintering seasons. Reconstruction and destruction of churches, buildings, bridges or mines also threaten the survival of these bats.

Conservation measures. Some caves are included to the list of natural monuments. The Magili Cave in the Noravank Canyon, Eghegnadzor district is closed to human visitations. Bat habitats should be granted the status of sanctuaries and closed to human visitations.
