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.

Population [top]

Population:The localities are mainly limited to Mt. Tsurugi and Mt. Ishizuchi, and each subpopulation is small, but current mature tree numbers are not confirmed.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:Yes

Habitat and Ecology [top]

Habitat and Ecology:It occurs near the summits of Mt. Ttsurugi and Mt. Ishizuchi where it forms dense forest on rocky ridges.
Generation Length (years):50

Use and Trade [top]

Use and Trade: No use recorded.

Threats [top]

Major Threat(s): The AOO is small, making the tree vulnerable to fire and other stochastic events.

Conservation Actions [top]

Conservation Actions: All habitats/ subpopulations are inside a National Park, and protected from logging.
