The Forest Community

 

Forest communities are much more than just an assembly of trees. They are an extremely complex, interacting, and coordinated system.  In fact you may have heard the word ecosystem.  "Eco" refers to the environment, in this case a forest, and "system" refers to the numerous interacting units (e.g. trees, soil, insects, birds, and man).  It is difficult to imagine a more complex  designed system than a forest ecosystem.

Scientists have spent their entire lifetimes trying to understand even a small part of forest ecosystems. Forest ecosystems are extremely diverse, ranging from dry desert shrub land to large temperate rain forests.  Scientists have categorized  forest ecosystems  in North America by placing them into biomes.  Biomes are broad categories of natural plant communities.  To learn more about the biomes found in North America click here- BIOMES.

 

  • Forest cover types are recognized by the Society of American Foresters. They refer to very specific combinations and proportions of trees and shrubs.
