PLANTAE	TRACHEOPHYTA	PINOPSIDA	PINALES	PINACEAE

Scientific Name:	Abies fargesii var. faxoniana
Species Authority:	(Rehd. & E.H.Wilson) T.S.Liu
Parent Species:	See Abies fargesii
Synonym/s:	Abies faxoniana Rehd. & E.H.Wilson

Assessment Information [top]

Red List Category & Criteria:	Vulnerable A2cde ver 3.1
Year Published:	2013
Date Assessed:	2010-12-14
Assessor/s:	Xiang, Q. & Rushforth, K.
Reviewer/s:	Thomas, P. & Farjon, A.
Justification: An estimated reduction of more than 30% in the past three generations (15 years) due to logging, means that this variety is assessed as Vulnerable.

Geographic Range [top]

Range Description:	Enemic to China, occurring from NW Sichuan, S & C Gansu, from Songpan north into the Min Shan and also in a subpopulation in central Gansu.
Countries:	Native: China (Gansu, Sichuan)

Population [top]

Population:	This variety forms forests in the Min Shan region. Subpopulations are fragmented in the southern part of its range with a disjunct outlier in central Gansu.
Population Trend:	Decreasing

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).
Systems:	Terrestrial
