abstract   bibtex   
[Excerpt] Betula nana is a characteristic, commonly occurring species of Arctic and alpine tundra and subalpine moorlands and bogs throughout its very broad range of distribution. There are no known threats that are or will adversely affect this species in the foreseeable future. It is assessed as Least Concern. [::Common Name(s)] [::]English - Arctic dwarf birch, Scrub birch, Dwarf Birch, Bog birch, Swamp birch [::]French - Bouleau nain, Bouleau nain d'Europe [::Taxonomic Notes] Ashburner and McAllister (2013) have combined Betula nana ssp. exilis into Betula glandulosa. The authors state '' We interpret the material traditionally referred to B. nana ssp. exilis as dwarf, mainly more northern, variants of B. glandulosa''. This assessment follows the taxonomy of Ashburner and McAllister (2013). [::Range Description] This species occurs in the Canadian Arctic archipelago from Baffin Island east to Greenland, Iceland, Scotland and adjacent northern England and Svalbard, Norway. In mainland Europe this species occurs in~Scandinavia~and the Baltic area, northern and central European Russia and western Siberia east to the Yenisey-Lena watershed. From its northern European distribution it occurs southerly to central Europe at high elevations in the mountains of the northern Alps from Austria west to France and high elevations in the Carpathian mountains from Poland and the former~Czechoslovakia~south to Romania. [::Countries] Native:Austria; Czech Republic; Estonia; Finland; France (France (mainland)); Germany; Greenland; Iceland; Italy (Italy (mainland)); Latvia; Liechtenstein; Lithuania; Norway; Poland; Romania; Russian Federation (Central European Russia, East European Russia, Irkutsk, Krasnoyarsk, North European Russia, West Siberia); Slovakia; Svalbard and Jan Mayen; Sweden; Switzerland; United Kingdom (Great Britain) [::Population] Betula nana is a common species across most of its broad geographic range. However, there are no hard data on population numbers due to it not being an important commercial species.\textasciitilde [::Habitat and Ecology] A deciduous much branched, dwarf shrub which grows to 50-100 cm high. It is a woody species of exposed Arctic and alpine tundra, rocky barrens and moorlands. In the southern part of its range in the northern Alps and Carpathian mountains of Europe it occurs in alpine tundra, subalpine damp moorlands, open raised bogs with Sphagnetum megellanici and pine moors. They are largely Arctic or high mountain plants of immature or peaty soils. [::Use and Trade] There is no commercial use of Betula nana. [::Major Threat(s)] No known threats have been identified for dwarf arctic birch (Betula nana).
