Abies recurvata var. recurvata
|Scientific Name:||Abies recurvata Mast. var. recurvata|
See Abies recurvata
|Taxonomic Source(s):||Farjon, A. 2010. A Handbook of the World's Conifers. Koninklijke Brill, Leiden.|
|Red List Category & Criteria:||Vulnerable A2d ver 3.1|
|Assessor(s):||Xiang, Q. & Rushforth, K.|
|Reviewer(s):||Thomas, P. & Farjon, A.|
A past reduction of more than 30%, but less than 50% is inferred to have occurred in the past 150 years (three generations) following extensive logging prior to the introduction of a logging ban in 1998. The reduction may been greater than 50% but more information is needed to confirm this. Consequently, this variety is assessed as Vulnerable.

|Habitat and Ecology:||Min Fir is a high mountain species of SW China, occurring between 2,300 m and 3,600 m a.s.l. or even higher. It grows usually on grey-brown mountain podzols. The climate is cold, moist, with annual precipitation between 700 mm and 1,000 mm. It is usually a constituent of a mixed coniferous forest type, with among other species A. squamata, Picea likiangensis var. rubescens, P. asperata, and Larix potaninii; Picea purpurea and Abies fargesii var. faxoniana are mainly found with the 'typical' variety, and A. fabri with var. ernestii. Betula albosinensis is the only common broad-leaved tree at higher elevations, but lower down the slopes other genera, e.g. Acer, Populus, but also different conifer species, e.g. Tsuga chinensis, Picea brachytyla var. complanata and Pinus armandii become more abundant.|
|Generation Length (years):||50|
|Use and Trade:||A timber tree in western China, heavily exploited until recently when the Chinese government finally decided to preserve its remaining old growth forests in the western provinces. Its timber was used mainly for construction and carpentry work. Although not common in cultivation it makes a desirable tree for cultivation in western gardens which would enhance its ex situ conservation|
|Major Threat(s):||Past logging has reduced the population. Future threats include acid rain and possibly climate change.|
|Conservation Actions:||The Government of China has recently imposed a logging ban in western China. This taxon may be included in some protected areas.|
