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.
|Range Description:||Recorded from the Nukiang River area in the northwestern Yunnan province, and Yongde shan, Wu Mu Long township, China. In Myanmar, it is known from Kachin state, Tama Bum.|

|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).|
|Current Population Trend:||Decreasing|
|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.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Generation Length (years):||50|
|Use and Trade:||Timber used locally. In Myanmar, an infusion of the leaves is used as a cure fore headaches.|
|Major Threat(s):||Logging is the most serious threat.|
|Conservation Actions:||The Government of China has recently imposed a logging ban in western China.|
