climax community
in ecology, the final stage of biotic succession attainable by a plant community in an area under the environmental conditions present at a particular time. For example, cleared forests in the eastern United States progress from fields, to old fields (with colonizing trees and shrubs), to forests of these early colonists, and finally to climax communities of longer-lived tree species. The species composition of the climax community remains the same because all the species present successfully reproduce themselves and invading species fail to gain a foothold. Because climatic changes, ecological processes, and evolutionary processes cause changes in the environment over very long periods of time, the climax stage is not completely permanent
