Assessment Information [top]

Red List Category & Criteria: Vulnerable D2 ver 3.1
Year Published: 2011
Date Assessed: 2010-12-16
Assessor(s): Katsuki, T., Rushforth, K., Zhang, D & Farjon, A.
Reviewer(s): Thomas, P. & Christian, T.
The population is restricted to a small area of occupancy (AOO) in only two forests, which would support a classification as Endangered but there is no evidence, or indication, of a continuing decline in the subpopulations. However, it is appropriate to list this taxon as Vulnerable as stochastic events like major forest fires could bring about a population reduction despite the protected status of the habitat.
Previously published Red List assessments:
1998 Lower Risk/near threatened (LR/nt)
1998 Rare (R)
