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.
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.
