Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2011
Date Assessed: 2010-12-14
Assessor(s): Rushforth, K., Xiang, Q. & Carter, G.
Reviewer(s): Thomas, P. & Farjon, A.
Justification:
The extent of occurrence is estimated to be about 20,000 km2 and although there are more than 10 locations known, the subpopulations are severely fragmented. There has been an estimated decline of between 20 and 50% over the last three generations. It is uncertain if there is a continuing decline in the main part of its range in China as logging has been banned in most mountainous areas. The situation in Myanmar is unclear but continuing decline due to ongoing logging is suspected. Due to the uncertainties of the extent of the past decline, and the situation in Myanmar Abies delavayi var. nukiangensis is assessed as Near Threatened.

Population [top]

Population: Logging has occurred within the range in China but officially ceased in c. 2000, with significant populations remaining in China. The situation in Myanmar is uncertain but it is highly likely that logging is occurring. Inferred population reduction of perhaps 25-50% within the last three generations (150 years).
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: Occurs on high montane settings and isolated peaks (such as Tama Bum in Myanmar) where it is the dominant species, occurring with Sorbus species, Acer, Rhododendron and similar woody temperate trees/shrubs including bamboo.
Systems: Terrestrial

Use and Trade [top]

Use and Trade: Timber used locally. In Myanmar, an infusion of the leaves is used as a cure fore headaches.

Threats [top]

Major Threat(s): Logging is the most serious threat.

Conservation Actions [top]

Conservation Actions: The Government of China has recently imposed a logging ban in western China.
