The term used to describe the natural regeneration of ecosystems after disturbances is ecological succession. This process occurs when an area experiences a significant change, such as a wildfire, flood, or human activity, and gradually transitions back to a stable ecosystem state. Primary succession begins on previously uninhabited land, while secondary succession occurs in areas where an ecosystem has been disturbed but soil and some organisms remain. Understanding ecological succession is vital for developing restoration strategies, as it highlights the resilience and recovery potential of ecosystems over time.
