The Betula Papyrifera is commonly known as the Canoe Birch, Paper Birch, Silver Birch as well as White Birch.

The currently accepted scientific name of paper birch is Betula papyrifera Marsh. . It is wide ranging and exhibits considerable ecotypic variation. Six intergrading geographical varieties are recognized : var. papyrifera - typical paper birch var. cummutata (Regel) Fern. - western paper birch var. cordifolia (Regel) Fern. - mountain paper birch var. kenaica (W. H. Evans) Henry - Kenai birch var. neoalaskana (Sarg.) Raup - Alaska paper birch var. subcordata (Rydb.) Sarg. - northwestern paper birch Birch (Betula spp.) is a genetically plastic genus, often with morphological variation continuous between species . Hybridization is common. Paper birch naturally hybridizes with almost every native species in the genus. Named hybrids include : B. p. var. neoalaskana x B. glandulosa = B. X eastwoodiae Sarg. (Syn. = B. X dugleana Lepage) B. papyrifera x B. nana = B. X hornei Butler B. papyrifera x B. populifolia = B. X caerulea Blanchard B. papyrifera x B. occidentalis = B. X utahensis (Britt.) Dugle (Syn.= B. X piperi Britton) B. papyrifera x B. pumila var. glandulifera = B. X sandbergii Britt. Crosses with yellow birch (B. alleghaniensis), sweet birch (B. lenta), and river birch (B. nigra) have not been named.

Paper birch has a transcontinental distribution across northern North America. It grows from Newfoundland and Labrador west along the northern limit of tree growth across Canada to northwestern Alaska, south to Washington, east and north in the mountains to western Montana and southwestern Alberta, east across the Prairie Provinces to Manitoba, and south and east through the Lake States to New England. Scattered outlying populations occur in the Great Plains of Montana and North Dakota, the Black Hills, the Appalachian Mountains from central New York to western North Carolina, and the Front Range of Colorado . Paper birch is cultivated in Hawaii . Detailed descriptions of the ranges of the six varieties are available .

In boreal spruce ecosystems, paper birch forms nearly pure, pioneer communities on disturbed sites. It is rare in late successional or climax forests and generally restricted to openings. It is a principal component of boreal mixedwoods in Canada because its pioneering habit is favored by the relatively frequent 50- to 125-year fire return interval . Codominants in mixedwoods include trembling aspen (Populus tremuloides), black spruce (Picea mariana), white spruce (P. glauca), jack pine (Pinus banksiana), and balsam fir (Abies balsamifera). In the Northern Great Plains, paper birch forms climax woodland communities on moist, north- or east-facing slopes .
