Habitat and Ecology [top]

Habitat and Ecology: Larix potaninii and its varieties are high mountain larches occurring between 2,350 m and 4,300 m altitude a.s.l. The soils are acidic mountain podzols. The climate is cold, the precipitation varies from 800 mm to 2,000 mm annually according to location. At high elevations it grows often pure, with undergrowth of Juniperus squamata, elsewhere it is usually mixed with Abies spp., Picea spp., Tsuga dumosa or T. chinensis, Cephalotaxus spp. and Taxus spp.
Systems: Terrestrial

Use and Trade [top]

Use and Trade: Chinese Larch is an important timber tree in the western mountains of China. Its wood is durable and can be used for construction purposes, mining props and railway sleepers, as well as milled for veneer and pulped for the paper industry. It is rarely used in forestry plantations outside China and for amenity planting. It is in cultivation  only as specimen trees in some arboreta and pineta; most trees in Europe and the USA derived from seed collected by Ernest Wilson and other plant collectors early in the 20th century and often have not survived. There are numerous recent collections planted, however, these are still confined to arboreta. This species should be planted more often in suitable regions (climate) as it has large, attractive cones with conspicuous upturned bracts

Threats [top]

Major Threat(s): Localized over exploitation of varieties with limited distribution has led to two varieties being listed as threatened. No range wide threats have been identified.

Conservation Actions [top]

Conservation Actions: This species occurs in several protected areas. A general logging ban is in place in China where the majority of the population occurs.
