|Scientific Name:||Abies chensiensis ssp. yulongxueshanensis|
|Taxonomic Source(s):||Farjon, A. 2010. A Handbook of the World's Conifers. Koninklijke Brill, Leiden.|
|Taxonomic Notes:||Rushforth (1984) described this subspecies from the main massif of the Lijiang Shan (Yulongxue Shan, 5,596 m) in NW Yunnan. It has somewhat larger cones than the type subspecies and marginal resin canals in the leaves of cone-bearing shoots. In the Flora of China 4 (Liguo et al. 1999) where no subspecies of A. chensiensis are recognized, this taxon has been treated as a synonym of Abies ernestii Rehd. var. salouenensis (Bord.-Rey & Gaussen) W.C.Cheng & L.K.Fu.|
|Red List Category & Criteria:||Least Concern ver 3.1|

|Reviewer(s):||Thomas, P. & Christian, T.|
Although this subspecies has a very small extent of occurrence and area of occupancy, there are no threats at present and the range is not severely fragmented. Hence it is listed as Least Concern.
|Previously published Red List assessments:||
|Range Description:||The population is restricted to a small area of forest at Lijiang Shan in Yunnan province, China.|
|Continuing decline in area of occupancy (AOO):||No|
|Estimated extent of occurrence (EOO) - km2:||169|
|Lower elevation limit (metres):||3000|

|Population:||This subspecies is only known from one mountain range in Yuong Shui Shan in NW Yunnan and is believed to count fewer than 1,000 mature trees. Parts of this mountain are a National Park and at least some of the population occurs within this protected area.|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||Found in high mountains in mixed coniferous forest at 3,000 m altitude and higher.|
|Continuing decline in area, extent and/or quality of habitat:||No|
|Generation Length (years):||15|
|Use and Trade:||No specific uses have been recorded.|
|Major Threat(s):||Logging has occurred in the past but a logging ban has been imposed by the Government of China.|
The Lijiang Shan is one of the best preserved areas and the majority of the population is found within the protected area.
Further research into the population size, range and particularly the threats is needed. If threats are identified (even potential threats), then the species could well be reassessed under a more threatened category.
