Over 90% of Canada's forests are owned by the public (Crown land and Provincial forest). About half of the forests are allocated for logging. Named forests are found within eight distinct regions. These forests may also be part of ecosystems, a number of which extend south into the United States. For example, the Northern hardwood forest is an ecosystem located in large areas of southeastern and south central Canada as well as in Ontario and Quebec. The Great Lakes region includes white pine, Apiaceae, hemlock and red maples, yellow birch, and beech trees. The Maritime Region, Maritime region is dominated by the red spruce, while the black spruce is prevalent in the Canadian Shield, eastern Laurentian, with spruce in the Canadian Shield, western Laurentian.

Canadian Shield
The Canadian Shield ( ), also called the Laurentian Shield or the Laurentian Plateau, is a geologic shield, a large area of exposed Precambrian igneous and high-grade metamorphic rocks. It forms the North American Craton (or Laurentia), the ancient geologic core of the North American continent. Glaciation has left the area with only a thin layer of soil, through which exposures of igneous bedrock resulting from its long volcanic history are frequently visible. As a deep, common, joined bedrock region in eastern and central Canada, the shield stretches north from the Great Lakes to the Arctic Ocean, covering over half of Canada and most of Greenland; it also extends south into the northern reaches of the continental United States. Geographical extent The Canadian Shield is a physiographic division comprising four smaller physiographic provinces: the Laurentian Upland, Kazan Region, Davis and James. The shield extends into the United States as the Adirondack Mountains ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

It is a hardy, fast-growing tree which is generally short lived, but some trees as old as 200 years have been found. The tree is known for its strong, sweet fragrance, which emanates from its sticky, resinous buds. The smell has been compared to that of the balsam fir tree.

White Birch
White is the lightest color and is achromatic (having no chroma). It is the color of objects such as snow, chalk, and milk, and is the opposite of black. White objects fully (or almost fully) reflect and scatter all the visible wavelengths of light. White on television and computer screens is created by a mixture of red, blue, and green light. The color white can be given with white pigments, especially titanium dioxide. In ancient Egypt and ancient Rome, priestesses wore white as a symbol of purity, and Romans wore white togas as symbols of citizenship. In the Middle Ages and Renaissance a white unicorn symbolized chastity, and a white lamb sacrifice and purity. It was the royal color of the kings of France as well as the flag of monarchist France from 1815 to 1830, and of the monarchist movement that opposed the Bolsheviks during the Russian Civil War (1917–1922). Greek temples and Roman temples were faced with white marble, and beginning in the 18th century, wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
