Conservation Status

Red List Category & Criteria: Least Concern

This species has an extent of occurrence of more than 20,000 km2, and has a large population and although there are past and ongoing threats, it is listed here as Least Concern. It is a rare species, usually mixed with Picea spp., Abies fargesii var. sutchuenensis, Tsuga chinensis, Larix potaninii at high elevations, and Betula spp. at lower elevations; also as a pure forest in Tsin-ling Shan (Wang 1961). Logging and deforestation have depleted this species to some extent in some parts of its range. The Chinese Government has recently imposed a logging ban on old growth forest in western China.
