Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Leary, T., Singadan, R., Menzies, J., Wright, D., Aplin, K. & Helgen, K.
Reviewer(s): Lamoreux, J. (Global Mammal Assessment Team) & Amori, G. (Small Nonvolant Mammal Red List Authority)
Justification:
Listed as Near Threatened because, although it is reasonably common within its small range, its extent of occurrence is less than 5,000 km2, and the extent and quality of its habitat are declining, thus making the species close to qualifying for a threatened category (under criterion B1). Further research into the response of this species to habitat degradation.
