succession (ecological)

The process whereby communities of plants, animals and microorganisms are replaced by others, usually more complex, over time as an area is colonized. Primary succession occurs on bare ground (e.g. after a volcanic eruption); secondary succession follows the interruption of a primary succession, e.g. after disturbances such as logging, ploughing or burning.
