Secondary succession refers to the concept of an ecosystem reviving itself after all or a portion has been destroyed. The concept refers primarily to plant life and can be the result of a natural or man-made event. The primary concept is that the life was previously on the soil, eliminating the need for deposition of new seeds or soil. Secondary succession is a much more rapid process than primary succession because the soil and nutrients are already available.
Examples of secondary succession include:
