Conservation Status

Red List Category & Criteria: Least Concern

Logging has affected many areas although with the introduction of a logging ban in 1998 this problem has reduced, the species as a whole is considered Least Concern. It grows mixed with other conifers, such as Picea likiangensis, Picea brachytyla var. brachytyla, or in pure stands towards the tree limit. At lower elevations it is sometimes mixed with Tsuga chinensis, Tsuga dumosa, Juniperus formosana and broad-leaved trees, e.g. Betula albosinensis, Betula platyphylla var. szechuanica, and Quercus semecarpifolia. Abies delavayi, however, is less common with these trees than Abies forrestii. The Government of China has recently imposed a ban on logging in western China.
