[Excerpt] This species has a wide range and is reported to be very common across its range. There are no known major threats to the survival of this species at present. It is therefore assessed as Least Concern. [::Common Name(s)] [::]English - Stone Birch, Erman's Birch [::Taxonomic Notes] Betula ermanii var. saitoana previously described as threatened is thought to be only a minor variant of B. ermanii. [::Range Description] The species occurs in Japan, extending north along the Kurile Islands and Sakhalin, on mainland Asia in northeastern China, Korea and Pacific Russia as far west as Lake Baikal in Siberia, also on the Kamchatka peninsula. In North Korea it has a known occurrence in two mountains, Myohyangsan at 1,060-1,790 m asl and Paekdusan at 900 m asl. [::Countries] Native:China (Heilongjiang, Jilin, Liaoning, Nei Mongol); Japan (Hokkaido, Honshu, Shikoku); Korea, Democratic People's Republic of; Korea, Republic of; Russian Federation (Amur, Buryatiya, Chita, Irkutsk, Kamchatka, Khabarovsk, Magadan, Primoryi, Sakhalin, Yakutiya) [::Population] This species has a wide range and is very common. [::Habitat and Ecology] This species is primarily a mountain tree which is a major if not the sole component of tree-line forests in Japan and Korea and mainland eastern Asia as far west as Lake Baikal. In Russia it is found on stony slopes mainly in the form of isolated stunted trees in thickets of cedar-pine forests and also forming stunted woodland. This species is sensitive to drought, which causes dieback, but is tolerant of wet soils. It prefers to grow in rich and moist soils with high humus content and is encountered more frequently on cool wet north facing slopes. [::Use and Trade] The wood is hard and dense, and is used for construction and making furniture. It is also cultivated as an ornamental with a number of varieties and unidentified hybrids. [::Major Threat(s)] This species is susceptible to the bronze birch borer (Agrilus anxuis) and sensitive to drought. It should be noted that the future climate may be drier in some some areas, and pest numbers may rise, which may increase the threat to this species in future.
