Red List Category & Criteria: Least Concern ver 3.1

This is a poorly known species. However, based on the extent of occurrence and remoteness of the area where it occurs it is assumed that there are no major threats. The small area of occupancy indicates a possible threatened listing, however, this is probably an under-estimate because it has not been collected that often. The species is therefore listed as Least Concern at this time. Further field surveys are required to determine what is happening to the species in the wild.

Previously published Red List assessments:
1998 Lower Risk/near threatened (LR/nt)
1998 Rare (R)

Population [top]

Population: This species is assumed to be common where it occurs, but surveys are required to confirm this. There is no information available on population trends.
Current Population Trend: Unknown
Additional data:

Habitat and Ecology [top]

Habitat and Ecology: This species has been found in deep gorges and on rocky or grass-covered slopes in the semi-arid mountains and plateaus of S Gansu, SE Qinghai and NW Sichuan, where it is associated with few other trees and mainly restricted to S-facing slopes. The altitudinal range is from 2,110 m to 4,000 m a.s.l. N-facing slopes are covered with spruce forest (Picea asperata).
Systems: Terrestrial
Continuing decline in area, extent and/or quality of habitat: No
Generation Length (years): 15

Use and Trade [top]

Use and Trade: No uses have been recorded for this species, but its wood and foliage may be used locally for firewood and incense burning. In cultivation it is only known in a few arboreta and these are recent introductions

Threats [top]

Major Threat(s): Due to the remoteness of the localities in which this species has been found it is not currently under threat; on the other hand the region and its forests and woodlands have not been visited by botanists regularly. A renewed survey is desirable especially to find whether the distribution data here presented are still coincident with its current occurrence.

Conservation Actions [top]

Conservation Actions:

It is not known if this species occurs in any protected areas. Surveys are required to determine the population size and trends of this species and to determine if there are any threats to warrant any concern.
