Old-growth forests are unique, usually having multiple horizontal layers of vegetation representing a variety of tree species, age classes, and sizes, as well as "pit and mound" soil shape with well-established fungal nets. [20] As old-growth forest is structurally diverse, it provides higher-diversity habitat than forests in other stages.
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.)
I would like to point out that old growth and virgin forests are not the same. Virgin forest are those that have never been cut. Old growth are secondary growth that have been cut in the distant past and have regrown. Maybe in a few thousands year old growth will resemble virgin forest, but not in out life time.
The Forest Service and federal Bureau of Land Management combined oversee more than 50,000 square miles (129,000 square kilometers) of old growth forests and about 125,000 square miles (324,000 ...
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]
Gains in forest land have resulted from conversions from crop land and pastures at a higher rate than loss of forest to development. However issues have been identified such as the continued loss of old-growth forest, [9] the increased fragmentation of forest lands, and the increased urbanization of forest land. [10]
