English Gaoshan Pine

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2013
Date Assessed: 2011-01-28
Assessor(s): Farjon, A.
Reviewer(s): Thomas, P.
Justification:
Pinus densata is widespread in the mountains of southwestern China. No declines have been reported so it is assessed as Least Concern.

Population [top]

Population: The population is assumed to be stable in the absence of any evidence of decline.
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: Pinus densata occurs in high mountains at altitudes from 2,600 m to 4,000 m a.s.l. or even above this line to 4,200 m. It forms open pure stands at the highest elevations, but becomes mixed with other pines, e.g. P. armandii and P. yunnanensis, below 3,000 m a.s.l. It is presumed that its hybrid characters include a greater tolerance to frost than either of its putative parents, P. tabuliformis and P. yunnanensis, enabling it to colonize right up to the present tree line in western China's great mountain system.
Systems: Terrestrial

Use and Trade [top]

Use and Trade: There is presently little economic use of this species, primarily because it occurs in high mountains in often inaccessible places. A traditional use at least a century ago seems to have been making torches, using wood and resin. It has been suggested that it would be suitable for afforestation (presumably forest restoration) in the alpine regions of western China. It was introduced in Europe (UK) about 100 years ago, but this species remains rare in botanic gardens and arboreta.

Threats [top]

Major Threat(s): No specific threats have been identified for this species.

Conservation Actions [top]

Conservation Actions: A general logging ban imposed by the Chinese Government since 2000 may have had some effect, but this species was not under heavy pressure from exploitation or deforestation generally. It is also known from several protected areas.
