Detailed explanation-1: -Secondary succession occurs when the severity of disturbance is insufficient to remove all the existing vegetation and soil from a site. Many different kinds of disturbances, such as fire, flooding, windstorms, and human activities (e.g., logging of forests) can initiate secondary succession.
Detailed explanation-2: -Floodplains represent (like landslides) an intermediate status between primary and secondary succession. At one extreme, floods can completely remove all prior vegetation and organic matter, triggering primary succession on a layer of fresh silt, sand, or gravel.
Detailed explanation-3: -Secondary succession happens when a climax community or intermediate community is impacted by a disturbance. This restarts the cycle of succession, but not back to the beginning-soil and nutrients are still present.
