Scientific Name: Belgrandiella angelovi
Species Authority: L. Pinter, 1968

Assessment Information [top]

Red List Category & Criteria: Vulnerable D2 ver 3.1
Year Published: 2010
Date Assessed: 2009-11-19
Assessor/s: Georgiev, D.
Reviewer/s: Van Damme, D., Feher, Z., Abdul Malak, D. & Seddon, M.B.
Justification:
Belgrandiella angelovi is only known from the type locality: a spring on Shipka pass in Stara Planina Mts. However, there are two or three small springs on this pass near a small village. Several of the springs are modified by concreting for catchment of water and the threats are disturbance to these sites from tourism and development.

This species has been assessed as Vulnerable D2, as there may be other springs in the area that contain the species and there are little recent data on the distribution of this species or on its population size. A Critically Endangered assessment cannot be supported until more data are available on level of threats to the species. However should this data become available then the species could be reassessed as Critically Endangered B2ab(iii) using the precautionary principle.




Geographic Range [top]

Range Description: Belgrandiella angelovi is endemic to Bulgaria, where it is known only from the type locality: a spring in Stara Planina Mts on the Shipka pass, although the exact position of the type locality is not known. However, there are two or three small springs on this pass near a small village and several of the springs have been modified by concreting to allow the offtake of water for the villages. It is possible that this species may have a wider distribution as many of the local springs have not been surveyed.

Population [top]

Population: When originally collecting in the 1960s, Pinter found this species to be abundant. However there are no recent data on the status of this species.
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: It is considered a freshwater, cold spring species.
Systems: Freshwater

Threats [top]

Major Threat(s): This area at the top of the pass has several small springs, which are vulnerable to change, from water use for the village, and by visitors and tourism development. There is a possible risk in the future of fluctuations in populations as the result of changes in water level. The species possibly occurs in other areas in the regions that are hardly accessible, which are less threatened by human impacts.

Conservation Actions [top]

Conservation Actions: There are no conservation actions in place specific to the species. Surveys are needed to determine range and population levels, and the threats to other sites if located.
