Ecological Sustainability Goals he loss of more than half of the original Everglades ecosystem makes full restoration and a complete return to historical conditions impossible. The charette, therefore, defined ecological sustainability goals as the recovery of the defining features of the original Ever- glades. Two critical ecological characteristics are the de- fining features for sustainability of the natural dynamics of the Everglades. Large space and time scales supported large populations of animals; localized climatic condi- tions, disturbances such as fires, freezes, and storms, and small variations in topography created and maintained a complex mosaic of habitats across the landscape. This mosaic is necessary to support the teeming life that was characteristic of the natural Everglades. The abundant native spe- cies and diverse mosaic of habitats of the natural Ev- erglades were sustained by an inter-play of fundamen- tal organizing forces across the landscape: the large spatial scale of the system, the patterns of dynamic water storage and sheet flow, and the low water nutrient levels of the re- gion. These features must be restored if a healthy Ev- erglades is ever again to be experienced. Ecological sustainability requires the scientific identification of an interacting set of ecological and societal conditions that constitute a healthy environment. The ecosystem management process is designed to adapt human/ environment interactions in order to achieve ecological and societal sustainability goals.
