Adaptive cycle

 Annapurana Conservation Area, Nepal

This example reveals the progression through the adaptive cycle using the historical timeline for the region. It is shown that the Annapurana Conservation Area as progressed through the stages of the adaptive cycle and was able to move to the reorganization phase following a collapse without losing critical functions of the system, including local control, protected area status, and sustainable resource use.

 

Tongass National Forest

The Tongass National forest provides a clear example of each phase of the adaptive cycle. This example also describes how the whole system did not move to a different phase unless two of its three subsystems (economic, political and ecological) moved to that next phase at the same time. The system remains in the collapse phase unable to reorganize.

 

Forest fires

The factors contributing to a forest fire, the amount of standing vegetation, the spatial distribution of the burnable material and how easily the fuel can be ignited, change over different time intervals. Fires occur when there is a convergence of the right conditions. This can be described as a cross-scale interaction. Ignitions operate on a short-time scale: plant growth occurs over years and fuel loads and drought cycles operate over decades. Spatially, ignitions are local, plant growth is local, while fuel loads can spread fires across large areas, and droughts can occur over even larger areas.
