Forests differ based on past management activities and site conditions (e.g., soils, water, climate). Differences in forests can be observed through comparisons of plant and animal communities and other non-living (abiotic) characteristics, such as forest light levels.
Forests can also be arranged on a continuum of natural ecological disturbance. As the reader may recall, an ecological disturbance is a process that impacts the amount of living material in a forest. Common ecological disturbances include fire, windthrow, insect and mammal herbivory, and ice damage. Some ecological disturbances occur more frequently and affect less area (e.g., windthrow of 1 acre in a northern hardwood forest ever 2-3 decades). Other ecological disturbances occur less frequently, but impact greater area (e.g., wildfire over 1,000s of acres of pine forest every century).
