Assessment Information [top]

Red List Category & Criteria: Critically Endangered B1ab(ii,iii,v)+2ab(ii,iii,v) ver 3.1
Year Published: 2006
Date Assessed: 2006-01-31
Assessor(s): Crivelli, A.J.
Reviewer(s): Freyhof, J. & Bogutskaya, N. (Mediterranean Workshop, Dec. 2004)
L. polylepis is only found in one location, Stanicka Jaruga, a stream 1 m wide and 2 km long (area of occupancy (AOO) <10 km² and extent of occurrence (EOO) <100 km²). There is also a continuing decline of AOO, habitat quality and mature individuals due to water extraction and introduced trout species.
Previously published Red List assessments:
1996 Endangered (EN)
1996 Endangered (EN)
