Ecological Succession

These flashcards cover key concepts related to ecological succession, including definitions and examples of primary and secondary succession.

Succession

A series of changes that occur in a community after a disturbance.

Climax community

A stable, mature community resulting from ecological succession.

Primary succession

Occurs after severe disturbances where no vegetation or soil remains.

Pioneer species

The first species that can colonize an area during primary succession, such as lichens.

Secondary succession

Occurs after a disturbance but soil is still present, and happens much faster than primary succession.

Disturbances

Events such as floods, wildfires, or farming that commonly change communities.

Examples of primary succession causes

Volcanic eruptions and glaciers retreating.

Examples of secondary succession causes

Forest fire, flood, and logging.

Ecological succession

The process of change in ecosystems after disturbances, leading to a stable climax community.
