Population [top]

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.
Population Trend:	Unknown

Habitat and Ecology [top]

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).
Systems:	Terrestrial
