found: Dunster, J.A. Dict. of natural resource management, c1996(Disturbance. A discrete force that causes significant change in structure and/or composition through natural events such as fire, flood, wind, or earthquake; mortality caused by insect or disease outbreaks, or by human-caused events such as the harvest of a forest. In forests, larger disturbances generally favour colonizing species, while smaller disturbances favour the competitive species. Typically, diversity in the landscape is greater with large disturbances at infrequent intervals. Small but frequent disturbances create high diversity at the stand or ecosystem level.)
