Scientific Name: Terranigra kosovica Radoman, 1978

Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2011

The species is close to qualifying as Vulnerable, as it is listed from less than 10 locations by Radoman (1983), however these are widely scattered over the Kosovo river catchments with an inferred extent of occurrence of 10,800 km2, and as the species is a subterranean species it may be present more widely than the current known sites suggests. The springs themselves are thought to be exploited by the local residents for their domestic water supply, and as such there may be disturbance of the site, including improvement of the water abstraction through concreting part of the spring site. Some residual threats lie in the nitrates and pesticides present in the water, however the extent of this threat is unknown.  As such the species is listed on a precautionary basis as Near Threatened (NT) approaching criteria B, pending revised data on distribution, population trends and threats.

Geographic Range [top]

Range Description:Radoman (1985) describes the species as restricted to the Kosovo Basin. The type locality was freshwater springs near Cma Zemlja, six km west of Nerodimlje, Kosovo, Serbia. Other locations were 12-13 km west of Urosevac town, a spring as Pridvorica village (near Velji Brijeg), prings at Ribraric-Kosovska Mitrovica, a spring at Crnoljevo village, Gornja Mahal (by the road between Stimlac and Prizren), and a spring between Mala and Velika Reka, at the source of the Nerodimka River (Radoman 1983).

Habitat and Ecology [top]

Habitat and Ecology:

Although Radoman (1985) described it as restricted to freshwater springs, it is a subterranean species that it also found in springs (Radoman, 1983).


Use and Trade [top]

Use and Trade: This species is not utilized.

Threats [top]

Major Threat(s): Most springs are exploited by the local residents for their domestic water supply or for agricultural purposes and hence the major threat is over-abstraction of water. In some parts of the range water pollution from agricultural sources may also be an issue.

Conservation Actions [top]

Conservation Actions: No conservation actions are currently in place, although the species was proposed as an addition to the Emerald List of protected species for Serbia and Montenegro, and it listed as a protected species in the First National Report of the Republic of Serbia to the United Nations Convention on Biological Diversity (Republic of Serbia Ministry of Environment and Spatial Planning 2010). Further data is need on population status, distribution, habitat trends and threats to confirm the conservation assessment of this species.
