Not all disturbances to ecosystems are undesirable. The fact, however, is that disturbance does change the structure of the ecosystem including impacting the biodiversity. The disturbance may benefit some species while it may be disadvantageous to some species. An example is that while a volcanic eruption might devastate a whole ecosystem, the recovered ecosystem after time may have an increased biodiversity than before.
