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. [19] As old-growth forest is structurally diverse, it provides higher-diversity habitat than forests in other stages.

[1] (NB: The terms "old growth" and "virgin" may have various definitions and meanings throughout the world. See old-growth forest for more information.)
Even-aged forest management is the harvesting system of choice in many parts of the world because it is often considered to be the only method that is economically viable. Forestry operations have extremely high variable costs- per hour expenses for harvesting equipment and per kilometer expenses for log transportation compose a very large ...
"The Northwest Forest Plan is a hugely important tool for the future of our national forests, and it needs to be updated based on the best available science to address increasing threats from ...
Concurrently, the Archaic Indians began using fire in a widespread manner.
