The Turnover

The patch turnover simply means the expected or observed time of replacement of a patch with another patch, or the recovery of the same type of patch after a disturbance event (Fig. 7.2).

The mosaic-cycle concept has been extensively used by vegetationists to explain the movement of vegetation according to patchy patterns.

Especially for plants with a very rapid growth rate, spatial turnover is the rule. For instance, annual plants can appear suddenly, bring pattern to the system and then as quickly as they sprouted, they may disappear.

The patch turnover can be produced by disturbances, such as flooding, wild fires, wind storms, tree fall, animal grazing, trampling, digging, or burrowing.
