|Taxonomic Notes:||The relationship with two other varieties of Abies delavayi (A. delavayi var. nukiangensis and A. delavayi var. motuoensis) needs further investigation. In particular the relationship of the Burmese subpopulations needs evaluating.|
|Red List Category & Criteria:||Least Concern ver 3.1|

|Population:||Subpopulation on the type locality of the Cang Shan stable; subpopulations further west, such as on the northern Nujiang Shan (Ziben Shan, near Caojian) have suffered severe logging.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||This is a subspecies of high elevations in the great mountain ranges of SW China, occurring between 2,400 m up to the treeline, usually between 3,000 m and 4,000 m, but not on south facing slopes. The soil is a grey brown mountain podzol. The climate is extremely wet, with cool summers and cold, snowy winters (annual precipitation ranges from 1,000 mm to 3,000 mm and more but predominantly during the growing season). It grows in pure forests or with Tsuga dumosa at the bottom of its range. Broadleaved associated may include Betula utilis, Acer, Sorbus, Rhododendron, Araliaceae and similar woody species of the cool temperate forest.|
|Generation Length (years):||50|
|Use and Trade:||Timber used as a building material and other local uses.|
|Major Threat(s):||Extensive logging has officially ceased over the China part of the range. No information for the situation in Myanmar.|
|Conservation Actions:||The Government of China has recently imposed a ban on logging in western China.|
