	Silver Birch - Wikipedia, the free encyclopedia
		Silver Birch (Betula pendula) is a widespread European birch, though in southern Europe it is only found at higher altitudes.
		It is also distinguished cytologically, Silver Birch being diploid (with two sets of chromosomes), whereas Downy Birch is tetraploid (four sets of chromosomes).
		Land of the Silver Birch is a traditional Canadian folk song.

		The classification unit of this document, the Community Alliance, is based on floristic composition and is roughly equivalent in magnitude to the "cover type" of the Society of American Foresters (Eyre, 1980).
		The basic unit of the classification is the "community element", a vegetation unit of uniform floristic composition, habitat and physiognomy.
		This level of the classification hierarchy has been adopted by the National Gap Analysis Program as a means to organize and standardize data collected in the ground-truthing portion of the project.

	WOOD SPECIES
		The term “Natural” or “Unselected” Birch means that the lumber or veneer may contain both the sapwood, or white portion, as well as the heartwood, or dark portion, of the tree in unrestricted amounts.
		Birch, in veneer form, is readily available in all “selections” and is usually rotary cut.
		The wood is weak in bending, compression, shock resistance and stiffness, with a poor steam-bending classification.

		River birch is occasionally harvested with other bottomland species for pulpwood [7], and is used in some areas for veneer [6].
		River birch may be the initial colonizer of sandbars, or may establish after sandbars are stabilized by more flood-tolerant alders (Alnus spp.) or willows (Salix spp.) [25].
		Of 13 species tested, river birch bark was intermediate in heat resistance in the 0.20-inch- (0.508-mm-) thick category, but ranked relatively lower with increasing bark thicknesses; even though the heat resistance of river birch bark increases with thickness, other tree species gain more heat resistance for the same amount of thickness gain [14].

		This effort is conducted in accordance with the TNC vegetation classification and criteria for defining each community or alliance.
		Because of logistical limitations (short field season, overall general inaccessibility and difficulty in reaching a large number of photo signatures within a relatively short period of time), field verification was not conducted on the island.
		The vegetation classification is continually advanced through the collection and analysis of new field data and will be greatly strengthened during the course of the USGS-NPS mapping efforts.

	Observation of western Siberian Wetlands by using remote sensing techniques: Estimation of methane emission
		Birch trees are dominant in forested areas and coniferous forests are found along rivers because soils have richer nutrients there.
		Bog_1 is identified as peat land with low pine trees and shrubs, bog_2 as peat land with sparse dwarf trees and shrubs, and bog_3 as peat land mainly with grasses such as sedges and cotton-grasses.
		This demonstrates that ecosystem classification by remote sensing techniques would be useful in extrapolating ground methane flux measurements to regional or global scale estimates of methane emissions.

	Conservation Ecology: Modeling Forest Succession among Ecological Land Units in Northern Minnesota
		Yellow birch was a dominant species toward the end of the run, although it had lower basal area compared with the drier phases.
		On the Guthrie Till Plain, many of the plots had a strong initial component of paper birch (Table 2); trembling aspen, a major species in the early-successional runs, was not a strong dominant in the field plots.
		Because soils are an integral part of ecological classification, it follows that the model can be used not only for assessing successional pathways among ecosystems, but also for predicting their response to silvicultural treatment.

		Version 2.0 of the DNR's native plant community classification is based strongly on plant species composition and was developed through analysis of extensive field data collected from sample plots in forests, prairies, wetlands, and other habitats.
		The classification is hierarchical, with vegetation units described at levels ranging from broad landscape-level ecological systems to local communities.

	Wisconsin NHI Natural Community Descriptions
		Stunted trees of white cedar (Thuja occidentalis), white birch (Betula papyrifera), showy mountain-ash (Sorbus decora) and green alder (Alnus crispa) are often present in crevices.
		Of potential interest from the perspectives of vegetation classification and restoration, white pine had the highest importance value of any tree in the Lake Superior region, as recorded during the original land survey of the mid-1800’s.
		Water depth is a controlling factor in the swales, and the vegetation may run the gamut from open (emergent marsh, fen, or sedge meadow), shrub (bog birch, alder), or forested wetlands (often white cedar, fl ash are prominent in these).

		This document describes and details the classification system implemented as part of the statewide land cover mapping project under development by the North Carolina Center for Geographic Information and Analysis (CGIA).
		This classification system is largely based on the document entitled A Standard Classification System for the Mapping of Land Use and Land Cover (hereafter referred to as the standard classification system), produced by the CGIA in February 1994.
		The standard classification system was developed as the result of a series of forums, workshops, and reviews by more than sixty public and private sector organizations representing the land cover data user community from mid-1992 through the end of 1993.
