Assessment Information [top]

Red List Category & Criteria: Vulnerable D2 ver 3.1
Year Published: 2011
Date Assessed: 2010-01-28
Assessor(s): Pešić, V.
Reviewer(s): Feher, Z., Seddon, M.B. & Nichols, C.
Justification:
This taxon is endemic to Croatia, where it is geographically restricted, and although nothing is known about the specific threats and population status, the general threats to habitats in the region (habitat degradation and over abstraction of water) suggest that the species could be listed as Vulnerable (VU), pending further research on the taxonomic status, or Data Deficient (DD) due to the lack of data. On the basis of the precautionary principle it is listed as Vulnerable (VU D2) pending better data on the range and taxonomic status.

Geographic Range [top]

Range Description: This species is endemic to Croatia and the caves at Ombla source (type locality) is the only location where it has been found in quantity, but often the material contains shell fragments, as it is found in material which washes out from the cave system. Schütt (2000) suggests that the three species of Emmercia, including this species, might be present in the Dalmatian and Montenegrina coastal strip from Metkovia to Kotor.
