This variety makes up the bulk of the population of Abies fargesii. Due to its wide distribution and despite some past decline, it is assessed as Least Concern.
|Range Description:||Endemic to China, occurring in S Gansu, W Hubei, Shaanxi, NW Sichuan, W Henan, and N Chongqing.|
Native:China (Chongqing, Gansu, Henan, Hubei, Shanxi, Sichuan)

|Population:||Subpopulations tend to be fragmented but contain sizeable numbers of trees and have a relatively large area of occupancy. The population is thought to be decreasing.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||Abies fargesii occurs in the high montane to subalpine zones of northern Central China, at elevations between 2,000 m and 4,000 m a.s.l. Soils are mostly grey brown mountain podzols. The climate is cold and moist. At its lowest elevation broad-leaved trees (e.g. Fagus engleriana, Davidia involucrata) are important, but A. fargesii mostly forms either pure forests or mixed coniferous forests with among other species Picea purpurea, P. asperata, P. neoveitchii, P. brachytyla, Larix potaninii, Abies chensiensis, A. recurvata, Tsuga chinensis and Taxus chinensis. Some broad-leaved trees are usually present: Betula spp., Populus spp., and many shrubs: Cotoneaster, Ribes, Spiraea, Rhododendron and Berberis are among the common genera (except in dense Picea-Abies forest).|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Generation Length (years):||50|
|Use and Trade:||Being the most widespread of firs in the high mountains of western China, this species has been subject to extensive exploitation for its timber. The wood, if of high grade, is used in construction (mainly indoor flooring, framing and joinery), otherwise it is applied in the paper pulp industry. Most botanical collectors active in western China in the first decades of the twentieth century encountered it or its varieties and the species has been introduced to Europe and the USA from these collections. Most trees still in cultivation date from these introductions and are generally confined to botanical gardens and arboreta.|
|Major Threat(s):||Past logging has reduced the population. Acid rain may be affecting the trees in part of its range.|
|Conservation Actions:||A general logging ban has been introduced. This variety is known from several protected areas.|
