Intensity as a Third Factor of Disturbance Regime and Its Effect on Species Diversity

Several models have been devised to relate patterns of succession to disturbance events. One model examines expected plant species diversity for cases where the area and interval of disturbance varies. That examination applies only to cases where dispersal is important to regeneration. Where species regenerate from buried seed or by resprouting, the intensity of disturbance will be more important than the area in affecting species diversity. The model for area is extended to another dimension and the projections of plant species diversity are presented.
