Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Soriano, P. & Tirira, D.
Reviewer(s): Amori, G. (Small Nonvolant Mammal Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
This species is listed as Near Threatened despite its large range, due to pressures on its habitat and the possibility of a species complex. This species is currently estimated to be in decline due to habitat loss due to deforestation and due to water pollution (semi-aquatic), however, it is not currently declining at a rate sufficient to qualify for Vulnerable under criterion A. If this is more than one species, than they need be reassessed.
