Abies fanjingshanensis 


Taxonomy [top]

Kingdom Phylum Class Order Family
Plantae Tracheophyta Pinopsida Pinales Pinaceae

Scientific Name: Abies fanjingshanensis
Species Authority: W.L.Huang, Y.L.Tu & S.Z.Fang
Taxonomic Source(s): Farjon, A. 2010. A Handbook of the World's Conifers. Koninklijke Brill, Leiden.
Taxonomic Notes: This species is closely related to Abies fargesii and is possibly only a subspecies, even though it occurs at least 500 km to the south of the nearest occurrence of A. fargesii in the NW of Hubei. Both Farjon (1990) and Flora of China 4 (1999: 46) have recognized it as a distinct species.

Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(v); C2a(ii) ver 3.1
Year Published: 2013
Date Assessed: 2010-12-13
Assessor(s): Yang, Y., Zhang, D, Li, N., Luscombe, D & Rushforth, K.
Reviewer(s): Thomas, P. & Farjon, A.
Abies fanjingshanensis' extent of occurrence is less than 20 km2, it is known from 2-5 locations (there is part of the mountain which is not impacted by the acid rain), and there is a continuing decline in the number of mature individuals. The population size is less than 2,500 mature individuals and all of these are in one subpopulation which is undergoing continuing decline. The species therefore qualifies as Endangered under the B and C criteria.
Previously published Red List assessments:
1998 Endangered (EN)
1998 Endangered (E)

Population [top]

Population: Is locally common, but many trees have died due to the impacts of acid rain. The population is estimated to number about 17,000 trees, but the number of mature trees is probably less than 2,500 (<10% of the population).
Current Population Trend: Decreasing
Additional data:
Number of mature individuals: 249 Continuing decline of mature individuals: Yes
Population severely fragmented: No
All individuals in one subpopulation: Yes

Habitat and Ecology [top]

Habitat and Ecology: This rare species has been found on Mt. Fanjing (Wuling Shan) at 2,100-2,300 m a.s.l. The climate on this mountain is cool and moist, with only a short summer season at this altitude. The species occurs there in a mixed forest with, among other species, Tsuga chinensis, Acer flabellatum, Rhododendron hypoglaucum, Enkiartnus chinensis and Prunus serrulata. Only a few Abies trees are found scattered in the forest.
Systems: Terrestrial
Continuing decline in area, extent and/or quality of habitat: Yes
Generation Length (years): 30

Use and Trade [top]

Use and Trade: Although potentially a timber tree, this species does not appear to be exploited at present.

Threats [top]

Major Threat(s):

Only known from a single locality with a small population in forest dominated by other tree species. Mt. Fanjing has a forest reserve which includes this species. The population has been in decline for some time because of the impacts of acid rain presumably caused by air pollution. The acid rain problem is ongoing.

Conservation Actions [top]

Conservation Actions:

The entire population occurs within a forest reserve.  Attempts are required to identify the source/s of the pollution which are resulting in acid rain to see if any mitigation measures can be taken. There is a botanic garden in Guizhou Province which has this species in cultivation and they have an ex situ cultivation programme underway
