|Scientific Name:||Abies fabri (Mast.) Craib ssp. fabri|
See Abies fabri

|Red List Category & Criteria:||Vulnerable A2acde ver 3.1|
|Assessor(s):||Xiang, Q. & Rushforth, K.|

Past logging and the past and current impact of acid rain on subpopulations close to the Sichuan pendi justifieslisting this subspecies as Vulnerable under criterion A2.
|Range Description:||Occurs in western Sichuan province, China.|

|Population:||Population size is many thousands but in fragmented forests on tops or upper reaches of mountains. The population is decreasing.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||The type location of Abies fabri is on Mt. Emei (Emei Shan), a mountain SW of Chengdu in Sichuan. The species occurs there at elevations between 2,000 m and 3,100 m a.s.l. [K.D. Rushforth, pers. comm.; Craib (1919) has given a range between 3,000 m and 3,600 m a.s.l.] in a humid, cool climate (mean temp. in Jan. -4ºC, in July +12.6ºC, annual precipitation >2,000 mm). There are some nearly pure stands and scattered trees on Mt. Emei, but elsewhere in W Sichuan the subspecies occurs mixed with Picea likiangensis, Tsuga chinensis and occasionally Larix potaninii.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Generation Length (years):||50|
|Use and Trade:||This subspecies is not known to be a commercially important timber tree, presumably due to its restricted occurrence (protected from exploitation on the 'holy' mountain Emei Shan). It is uncommon in cultivation and mostly restricted to arboreta and botanic gardens.|
|Major Threat(s):||The type locality is the Emei (Omei) Shan to the south west of Chengdu which is a protected site, as is the Erlang Shan, Wa Shan and Wawu Shan. Other forests are not in protected areas and have suffered logging over the past century. However, the populations near the Sichuan pendi, in particular, are vulnerable to acid rain from industries near Chengdu. Acid rain appears to be the most serious threat to the species, causing decline or death of trees observed on Emei shan between 1980 (KR observation) and 2009 (Qiaoping Xiang record from husband and students).|
|Conservation Actions:||The mountain Emei Shan is a principal ‘holy mountain’ in Chinese Buddhism, consequently this species enjoys protection from exploitation there. The Government of China has also recently imposed a logging ban in western China.|
