Secondary succession occurs when a new set of organisms appears where there was an ecological set-back (for example a clear-cut logging operation) but where a cover of living plants was left ...

Secondary succession occurs after a fire or other disturbance when the landscape is significantly altered, but the building blocks of soil are already present.

In the case of primary succession, a region that is uninhabited by any species gets occupied by a few species over a period of time.

Ecological succession is the process by which biological community composition- the number and proportion of different species in an ecosystem- recover over time following a disturbance event.
