Betula Chinensis - Version 2014.3. Shaw, K., Roy, S., & Wilson, B. In The IUCN Red List of Threatened Species, pages 194283/0+. 2014. abstract bibtex [Excerpt] This species is common across its distribution and there~are no known threats that are or will adversely effect~the species in the foreseeable future.~In the Chinese Red List this species is assessed as Least Concern. This species is assessed here as Least Concern. [::Common Name(s)] [::]English - China birch, Chinese dwarf birch [::Taxonomic Notes] This species has a morphologically distinct 6x cytotype known only from two high mountains in South Korea whose conservation status is uncertain. The species otherwise is 8x which is common. Until more collections of both types have been checked and compared, and a geographical difference has emerged, the two types do not merit different names. [::Range Description] The species is known from northeastern China, where it is found near Beijing, possibly as far west as Gansu, and on the Korean Peninsula. [::Countries] Native:China (Gansu, Hebei, Henan, Liaoning, Nei Mongol, Shaanxi, Shandong, Shanxi); Korea, Democratic People's Republic of; Korea, Republic of [::Population] Betula chinensis is a common species with quite a large geographic distribution across northeastern China, however there are no hard data on population numbers due to it being common. [::Habitat and Ecology] A shrub or small tree to five metres, it~grows well in moist, warm-temperate climates and can be found in broad-leaved forests in mountain valleys and shaded rocky mountain slopes.~The young shoots of this species are not frost hardy, it therefore requires a long frost-free growing season. It also needs adequate summer warmth and rainfall evenly distributed throughout the growing season. Frosts in late spring after the buds have broken can sometimes kill quite large trees. This species has a very vigorous, deep root system, perhaps more so than any other birch. Established bushes on deep soils may be expected to be drought tolerant and, given adequate summer warmth and a long growing season, tolerant of exposure as well. [::Use and Trade] The wood from this species is of good quality, it is extremely hard and dense, close grained, very fine textured and is used for making pestles and wagon axles. It is one of the most valuable timber trees in north China. [::Major Threat(s)] There are no reported major threats to this species.
