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.)
Acidification of precipitation by anthropogenic, acid-forming emissions has been associated with damage to vegetation and reduced forest productivity, but 2-year-old white spruce that were subjected to simulated acid rain (at pH 4.6, 3.6, and 2.6) applied weekly for 7 weeks incurred no statistically significant (P 0.05) reduction in growth ...

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]
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 ...
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 ...
The forest is administered by Quebecʻs Ministry of Natural Resources, Wildlife and Parks, Forest Environment Directorate. [4] It was designated old-growth forest in 2005, and has IUCN management category III. [5] A map of the ecological regions of Quebec shows the Lac Auger Old Forest in the east spruce/moss subdomain.
