|Reviewer(s):||Thomas, P. & Christian, T.|
This subspecies 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.
|Previously published Red List assessments:||
|Range Description:||Endemic to China; this subspecies has a fairly wide distribution being recorded from SE Gansu, Henan (Nexiang), W Hubei, S Shaanxi, and W Sichuan.|
Native:China (Gansu, Henan, Hubei, Shaanxi)
|Continuing decline in area of occupancy (AOO):||Yes|
|Estimated extent of occurrence (EOO) - km2:|
|Lower elevation limit (metres):||2100|
|Upper elevation limit (metres):||3000|

|Population:||This subspecies is rare and is very scattered. A community inventory conducted for this species produced an estimate of 200,000 trees (Y. Yang pers. comm. 2010), but it is unsure what proportion of these were mature.|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||This variety occurs in high mountain ranges of the SW Plateau of China between 2,100 and 3,000 m asl, on grey-brown mountain podzols, brown earth or lithosols. The climate is cold and moist, with annual precipitation between 1,000 and 2,000 mm. 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).|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Generation Length (years):||15|
|Use and Trade:||Timber has been used for general construction work.|
|Major Threat(s):||Logging and deforestation have depleted this most common and widespread subspecies. Logging was mostly a threat in the past.|
|Conservation Actions:||The Chinese Government has recently imposed a logging ban on old growth forest in western China. Occurs in protected areas. Need further research on the range and population status of this taxon.|
