      Succession is the gradual change in the species composition of a community over time. Th e change can be a result of shift s in the population sizes of some of the species and by the appearance and disappearance of species. Primary Succession Primary succession is succession that takes place on completely barren rock or mineral deposits.

      The classic idea of succession also mandates that com-munities occur in discrete successional stages, with tem-poral transitions occurring quickly, followed by relatively stable periods. During the last 30 years, many workers have determined that development is a gradual process and that stages are convenient, but arbitrary, designations.
