Assessment Information [top]

Red List Category & Criteria: Vulnerable B1ab(iii) ver 3.1
Year Published: 2008
Date Assessed: 2008-01-01
Assessor(s): Esser, L. and Cumberlidge, N.
Reviewer(s): Darwall, W. (IUCN Freshwater Biodiversity Assessment Unit), Pollock, C.M. (IUCN Red List Unit) and McIvor, A.
Justification:
The assessment by Bahir et al. (2005) listed this species as Near Threatened. However the data given supports a listing as Vulnerable, because extent of occurrence is 10,000 km², number of locations is 7, and it lives in a habitat that is threatened by future human induced habitat loss/degradation due to human population increases and industrial and agrarian development. This species is found in a protected area but this is not considered sufficient to protect it from these threats.
History:
2006 Not Evaluated (IUCN 2006)
2006 Not Evaluated
