Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2013
Date Assessed: 2010-12-17
Assessor(s): Carter, G. & Farjon, A.
Reviewer(s): Thomas, P. & Christian, T.
At present, there is no decline recorded for this species. Most of its subpopulations are in very remote mountain ranges. There is a possibility that exploitation will increase in future, due to increased demand for timber. At this stage Picea crassifolia is assessed as Least Concern.

Habitat and Ecology [top]

Habitat and Ecology:Picea crassifolia occurs in high mountain ranges of Central Asia, mainly on north-facing slopes, above steppe or desert, at elevations between 1,600 m and 3,800 m a.s.l. It occurs on calcareous and non-calcareous soils (the first soil type e.g. in Helan Shan). The climate is cold continental and dry, with most of the precipitation falling as snow. It forms mostly pure forests, here and there with Betula albosinensis and groves of Populus tremula.
Continuing decline in area, extent and/or quality of habitat:No
Generation Length (years):25

Use and Trade [top]

Use and Trade: Qinghai Spruce is probably only locally exploited for its timber (firewood?), as it occurs remote from any major urban centres and even major roads. It is not uncommon in cultivation in botanic gardens and arboreta in Beijing, St. Petersburg and Moscow. In the West it is now also appearing, but still very rare; some trees are possibly misidentified, e.g. as Picea asperata.

Threats [top]

Major Threat(s): Logging could be a threat although China's current policies (e.g. the National Forest Conservation Programme) restrict this activity in sensitive areas.

Conservation Actions [top]

Conservation Actions: This species is present in several protected areas and also occurs in remote areas where there has been little disturbance.
