One example is when a large area of forest is blown down by a hurricane. Another is when a 26 1 A Systems (Holistic) Approach to Sustainable Agriculture forest is cut down and immediately replaced with a tree plantation. In the latter case, the species composition of the below-ground community may change, but the flow of organic matter from litter into the soil is interrupted only for a short time, and nutrient recycling and conservation functions continue. • A severe disturbance is where both the above-ground structure of the ecosystem is destroyed and the soil is severely degraded.

The system is maintained, though not at a fixed set point. Indirect effects can be as important or more important than direct effects in maintaining systems stability. On Isle Royal in Lake Superior, the dynamics of the browse-moose-wolf food chain (Moffat 1993; Vucetich and Peterson 2004) are particularly illustrative.
