A sequence of biotic changes that regenerate or create an ecological community is known as ecological succession.
Ecological succession is the process of change in an ecological community's species composition over time. The time frame can span several decades or fewer (for instance, following a wildfire). The community grows through an increase in complexity from a small number of pioneering plants and animals to a stable or self-sustaining climax community.
Succession is a process that occurs after a disturbance or the early colonization of a new environment. It involves changes to an ecological community that are more or less predictable and orderly. Secondary succession refers to succession that occurs after a pre-existing community has been disrupted, whereas primary succession refers to succession that starts in new environments with no impact from pre-existing groups.
