Disturbance of soils and ecosystems occurs through human and natural actions such as tillage, fire, grazing and drought.  The type, timing, intensity and frequency of disturbance interact with ecosystems to drive change.  The changes observed in soil and vegetation depends on the initial status of the system and the resistance and resilience of the system to change.  This symposium will focus on the effects of disturbance drivers on ecosystem attributes, including dynamic soil properties, and the interactions between disturbance, ecosystems and soil change.
