abstract   bibtex   
[Excerpt] This species has a wide distribution and no known major threats. It is listed as Least Concern in the Chinese Red List and is therefore assumed not to be threatened.~Betula dahurica~is assessed as Vulnerable in Japan, but due to its wide global distribution it is considered to be locally threatened in Japan, but not globally threatened.~It is assessed here as Least Concern. [::Common Name(s)] [::]English - Asian Black Birch [::Taxonomic Notes] Betula dahurica~occurs as two cytotypes, which are rather similar to one another. The octoploid cytotype is common and widespread in continental northeastern Asia including Korea, but the hexaploid is rare and found in Japan and the Kurile Island of Iturup.It has been proposed by Ashburner and McAllister (2013) that the continental octoploid cytotype is recognised as var. dahurica,~the Kurile Island and Hokkaido populations as var.~okuboi, and the more distinct Honshu populations as var.~parvifolia. [::Range Description] This species is native to East Asia, occurring east of Lake Baikal south to eastern Mongolia, China and Korea (occurring in all provinces except Chungcheongnam-do and Jeollanam-do), Japan and the Kurile Islands. [::Countries] Native:China (Hebei, Heilongjiang, Jilin, Liaoning, Nei Mongol, Shaanxi, Shanxi); Japan (Hokkaido, Honshu); Korea, Democratic People's Republic of; Korea, Republic of; Mongolia; Russian Federation (Amur, Chita, Khabarovsk, Kuril Is., Primoryi) [::Population] In the wild, this species occurs as two cytotypes, which are rather similar to one another and have not previously been recognized (until Ashburner and McAllister 2013). The octoploid cytotype of B. dahurica~is common and widespread in continental northeastern Asia including Korea, but the hexaploid is rare and found in Japan and the Kurile Island of Iturup. It has been proposed by Ashburner and McAllister (2013) that the continental octoploid cytotype is recognised as var. dahurica, the Kurile Island and Hokkaido populations as var. okuboi, and the more distinct Honshu populations as var. parvifolia. [::Habitat and Ecology] This species occurs as a tree to 20 m tall. This species occurs in mixed or coniferous forests, on dry or moist soils and exposed rocky places. In some situations it can be the dominant or co-dominant species in the forest. [::Use and Trade] The wood is hard and dense, and is used in house construction and for making agricultural tools and furniture. [::Major Threat(s)] There are no major threats reported for this species.
