It is a phenomenon or process by which an ecological community undergoes more or less orderly and predictable changes following a disturbance or the initial colonization of a new habitat. A landscape ecologist observes in area right after a volcanic eruption. This community becomes more complex as new species arrive. Plant Succession Trees play a major role in creating terrestrial plant cover when conditions develop to the point where some bare-ground and soil is present. For example, species diversity almost necessarily increases during early succession as new species arrive, but may decline in later succession as competition eliminates opportunistic species and leads to dominance by locally superior competitors.
