This is a list of areas of existing old-growth forest which include at least 10 acres (4.0 hectares) of old growth. Ecoregion information from "Terrestrial Ecoregions of the World". [1] (NB: The terms "old growth" and "virgin" may have various definitions and meanings throughout the world. See old-growth forest for more information.)
Old growth forests and "ancient woodlands" — of varying species, habitats and climates around the world. See also: List of old growth forests . Wikimedia Commons has media related to Primeval forests .
Therefore, for most people, the physical size of the trees is the most recognized hallmark of old-growth forests, even though the ecologically productive areas that support such large trees often comprise only a very small portion of the total area that has been mapped as old-growth forest. [24] (In high-altitude, harsh climates, trees grow ...
In the Olympic National Forest in Washington, Sitka spruce trees near the ocean sometimes develop burls. According to a guidebook entitled Olympic Peninsula, "Damage to the tip or the bud of a Sitka spruce causes the growth cells to divide more rapidly than normal to form this swelling or burl. Even though the burls may look menacing, they do ...
In forest complexes located south and southwest of the Białowieża Forest, the share of spruce sharply decreases, its role suddenly limited to a sporadic admixture. The closest dense spruce stands to the south of the forest are between 80 and 100 km away. [5] In hornbeam-oak forests, spruce surpasses all other trees in height. [33]
Old growth is defined as those forests that have not been logged (and have not been significantly disturbed by human beings) in the last 150 years. "Virgin forests" are those old-growth forests that show no sign of having ever been logged. A total of 2,742 acres (1,110 ha) of old-growth forest has been identified in Massachusetts. [1]
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.
Taiga or tayga (/ ˈ t aɪ ɡ ə / TY-gə; Russian: тайга́, IPA:), also known as boreal forest or snow forest, is a biome characterized by coniferous forests consisting mostly of pines, spruces, and larches. The taiga, or boreal forest, is the world's largest land biome. [1]
