Habitat and Ecology [top]

Habitat and Ecology:A. fargesii var. faxoniana  occurs in the high montane to subalpine zones of northern Central China, at elevations between 3,000 m and 3,600 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 [top]

Use and Trade: This variety (and the species as a whole) was heavily exploited in the past for construction timber.

Threats [top]

Major Threat(s): Past logging has reduced the population by more than 30%. There is an on-going risk from acid rain in parts of the population.

Conservation Actions [top]

Conservation Actions: Logging of this variety is now banned.
