Second-growth forests are the largest of the three major forest types because of the ecological success of governmental and environmental mandates.

Second-growth Forests

Forests which have re-grown after a significant disturbance, such as logging or a natural event, and are in a secondary stage of development.

Ecological Success

Refers to the process through which ecosystems change and develop over time following a disturbance or initial colonization, leading to a mature or climax community.
