Over several decades, the biological community transitions from collections of pioneer and intermediate species to a climax communitythat is, a relatively balanced ecological stage whose ecological structure and species composition are far less volatile than those of earlier stages. Ecological succession was first documented in the Indiana Dunes of Northwest Indiana and remains at the core of much ecological science. The stage leading to the climax community is called successional stages or seres. In general, communities in early succession will be dominated by fast-growing, well-dispersed species (opportunist, fugitive, or r-selected life-histories).

The stages of primary succession include pioneer microorganisms,[14] plants (lichens and mosses), grassy stage, smaller shrubs, and trees. Grasses are also early successional species because they reproduce quickly and require minimal diversity of resources to survive. Each transitional community that is formed and replaced during succession is called a stage in succession or a seral community.

The French naturalist Adolphe Dureau de la Malle was the first to make use of the word succession concerning the vegetation development after forest clear-cutting. It differs most fundamentally from the Clementsian view in suggesting a much greater role of chance factors and in denying the existence of coherent, sharply bounded community types.
