Assessment Information [top]

Red List Category & Criteria:

Near Threatened ver 3.1

Year Assessed:

2008

Assessor/s:

Woinarski, J.

Reviewer/s:

Lamoreux, J. & Hilton-Taylor, C. (Global Mammal Assessment Team)

Justification:
Listed as Near Threatened because there are less than 10,000 mature individuals, and that number is declining; there have been 20-30% declines in two sites, and the species has been completely lost from another site. The overall magnitude of declines for the population as a whole is unknown, but it is thought to be less than 10% within 10 years making the species close to qualifying as Vulnerable under criterion C.

History:

1996
