Spruce–fir forests can be found in cold regions at high latitudes or high altitudes throughout the Northern Hemisphere. [1] This includes both areas throughout the high latitude boreal forest of Canada and Russia, [2] [3] as well as mountain ranges at lower latitudes, such as the Rocky Mountains in North America, the Tian Shan in Asia, and the Carpathian Mountains in Europe.
Pseudotsuga macrocarpa, commonly called the bigcone spruce or bigcone Douglas-fir, is an evergreen conifer native to the mountains of southern California. It is notable for having the largest (by far) cones in the genus Pseudotsuga , hence the name.
Picea glauca (Moench) Voss., the white spruce, [4] is a species of spruce native to the northern temperate and boreal forests in Canada and United States, North America.. Picea glauca is native from central Alaska all through the east, across western and southern/central Canada to the Avalon Peninsula in Newfoundland, Quebec, Ontario and south to Montana, North Dakota, Minnesota, Wisconsin ...
Coast Douglas-fir is the fourth tallest conifer and fifth tallest of all trees in the world (after sitka spruce).Currently, coast Douglas-fir trees 60–75 metres (197–246 ft) or more in height and 1.5–2 metres (4.9–6.6 ft) in diameter are common in old growth stands, [4] and maximum heights of 100–120 metres (330–390 ft) and diameters up to 4.5–5.5 metres (15–18 ft) have been ...
Picea rubens, commonly known as red spruce, is a species of spruce native to eastern North America, ranging from eastern Quebec and Nova Scotia, west to the Adirondack Mountains and south through New England along the Appalachians to western North Carolina and eastern Tennessee.
The represented forest may consist of very deep trees, so if we represent the forest as a plain collection of parent pointer trees, it might take us a long time to find the root of a given node. However, if we represent each tree in the forest as a link/cut tree, we can find which tree an element belongs to in O(log(n)) amortized time. Moreover ...
The Sitka spruce zone–in which hemlocks also occur in large numbers–may be only a few kilometers in width and generally occurs below 150 m (490 ft). Where mountains abut the coast, however, Sitka spruce forests may extend up to 600 m (2,000 ft). [2] Riparian forests of this ecoregion are quite distinct from the Douglas-fir/hemlock forests.
Temperate coniferous forest is a terrestrial biome defined by the World Wide Fund for Nature. Temperate coniferous forests are found predominantly in areas with warm summers and cool winters, and vary in their kinds of plant life.
