Birch
(Betula spp. /Betulaceae). The genus Betula
contains about 40 species native to Asia, North America and
Europe. All species are identical at the cellular level. In
North America, Birches grow from the Tundra in the north throughouCanada,
south to Georgia (in the Appalachians). The treest
can attain heights of 70 ft, with diameters of more than 2 ft.
The wood of Birches varies slightly among species with respect
to physical and mechanical properties. The wood of birches is
heavy, hard and strong with a fine, uniform texture. The Birches
have white sapwood and reddish brown to dark brown heartwood.
It is used for lumber (baskets, boxes, cooperage, crates, doors,
distillation products, fuel wood, furniture, ice cream sticks,
interior finish, pulp wood, tongue depressors, toothpicks, turned
products, including spools, bobbins, small handles, toys and
woodenware) and veneer (aircraft, furniture, paneling, plywood
used for flush doors, radio and television cabinets).
