Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2013
Date Assessed: 2010-12-16
Assessor(s): Zhang, D, Rushforth, K. & Katsuki, T.
Reviewer(s): Thomas, P. & Farjon, A.
Abies forrestii var. ferreana is assessed as Least Concern based on its broad distribution and the relative stability other subpopulations. Although a significant decline as a result of deforestation, logging and grazing has occurred in the Zhongdian area, this represents a relatively small part of the total population and distribution. If declines occur in other areas, then a full reassessment will be necessary.

Geographic Range [top]

Range Description:Endemic to China: Yunnan, SE Xizang [Tibet]. It has been recorded from Zhongdian as far west as the Doshong La in Xizang.
Countries occurrence:
China (Tibet [or Xizang], Yunnan)
Additional data:
Lower elevation limit (metres):3000
Upper elevation limit (metres):4200

Population [top]

Population:This taxon occurs in pure or mixed forests in the upper temperate and subalpine zones.  The population is fragmented by natural features such as the deep river valleys in the area.  It is also severely fragmented in the Zhongdian area by deforestation for grazing and for logging where different conifer taxa have been replanted.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Grows in cool temperate and subalpine forests, mainly pure but also occurring in small mixtures with Betula and other conifers. Occurs between 3,000 and 4,200 m asl.
Generation Length (years):50

Use and Trade [top]

Use and Trade: The timber of this variety has been used for construction and for pulp.

Threats [top]

Major Threat(s): Logging, especially when followed by grazing (as at Zhongdian where there are yaks), by fire and by the planting of other conifer species are the main threats.

Conservation Actions [top]

Conservation Actions: The Government of China has recently imposed a logging ban in western China. It is desirable from a conservation perspective than any replanting of logged forests uses locally sourced nursery stock.
