A stand-based model for predicting basal-area mean diameter growth for Norway spruce (Picea abies (L.) Karst.) in young mixed stands of spruce and birch (Betula pendula Roth, B. pubescens Ehrh.) was developed and compared with two existing growth models developed for older main data were from experiments with four different pre-commercial thinning regimes. azərbaycanca: Tükcüklü tozağacı беларуская: Бяроза пушыстая català: Bedoll pubescent kaszëbsczi: Òbmeszonô brzózka dansk: Dun-Birk Deutsch: Moor-Birke English: Downy Birch Esperanto: Lanuga betulo español: Abedul pubescente eesti: Sookask euskara: Urki zuri suomi: Hieskoivu français: Bouleau pubescent galego: Bidueiro.

Betula pendula, commonly known as silver birch, warty birch, European white birch, or East Asian white birch, is a species of tree in the family Betulaceae, native to Europe and parts of Asia, though in southern Europe, it is only found at higher altitudes. Its range extends into Siberia, China, and southwest Asia in the mountains of northern Turkey, the Caucasus, and northern Iran.
The phylogenetic relationships within the genus Betula (Betulaceae) were investigated using a part of the nuclear ADH gene and DNA sequences of the chloroplast matK gene with parts of its flanking regions. Two well‐supported phylogenetic groups could be identified in the chloroplast DNA sequence: one containing the three American species B. lenta, B. alleghaniensis, and B. papyrifera and.

Two species of birch are found in natural habitats in Iceland: dwarf birch (Betula nana L., diploid with 2n = 2x = 28) and downy birch (B.
pubescens Ehrh., tetraploid with 2n = 4x = 56).Betula nana, a circumpolar species (de Groot et al., ), grows up to about 1 m in height with procumbent, wide-spreading stems and a strong branching habit.

The record derives from WCSP (data supplied on ) which reports it as an accepted name (record ) with original publication details: Beitr.
Morphometric parameters of mature leaves (area, venation density, and shape coefficient) and trunks (size and biomass) of two edificatory birch species, Betula pendula Roth and B. pubescens Ehrh., were characterized. These species inhabit a km transect of the Urals, from forest-tundra to forest-steppe.

Birch trees (Betula L.) are among the most common deciduous trees in the boreal and temperate zones of the Northern ing to different authors, in these zones there are more than 65 species of the genus Betula, however, European forests are dominated by two species: silver birch (Betula pendula Roth) and downy birch (Betula pubescens Ehrh.) (Hynynen et al.
Abstract. Icelandic birch (Betula pubescens Ehrh.) is the major indigenous woody species in vation of the remaining native birch forests is a recognized priority. The species has little commercial value because of its slow growth and irregular form; however, it is important for land reclamation, environmental protection, amenity planting, and for nature reserves.
The essential oils of the leaves of Betula pendula Roth., Betula pubescens Ehrh., Betula humilis Schrank and Betula nana L. (Betulaceae), and B. pendula buds were obtained using hydrodistillation and their chemical compositions were analyzed using gas chromatography and gas chromatography – mass spectrometry.
The yield of essential oil was the highest (%) in leaves of. In Europe, B. verrucosa and B. pubescens are naturally infected with cherry leaf roll virus (CLRV) which causes foliar mottle, pale yellow spots and bright green vein banding.
In the United Kingdom, the prevalence of CLRV in unmanaged birch populations is less than in street trees. How do different competing species influence the response of Betula pubescens Ehrh.

In Europe, two commercially important treelike birch species occur naturally: silver birch (Betula pendula Roth) and downy birch (Betula pubescens Ehrh.).
Silver birch and downy birch resemble each other in their general appearance, i.e. they are both white-stemmed and usually monocormic trees, reaching a height of 20–30 m.
