Isle au Haut Principles he U.S. Man and the Biosphere Program is con- ducting a 5-year interdisciplinary study on ecosystem management for sustainability. In June 1994 at Isle au Haut, Maine, a charette was con- vened to apply these concepts to South Florida as a case study. The charette concluded that what is being done now for Everglades restoration will not achieve ecologi- cal sustainability. A sustainable South Florida envi- ronment is achievable only through utilizing ecosys- tem management principles that recognize the inter- dependency of humans and their environment. The resulting vision for South Florida would provide for the long-term security of both the ecological and agricultural systems of the region, while supporting the adjacent urban area. The core of the South Florida ecosystem is the Everglades Biosphere Re- serve, a treasured natural resource of significant re- gional, national, and inter- national value. It is part of a human-dominated South Florida ecosystem, whose ecological sustainability is threatened by the pressures of urban and agricultural development. The upland, wetland, and coastal ecological systems that make up the Everglades of South Florida are unique in the world. The people of South Florida require the economic support, clean water supply, flood control, recreational experiences, environmental quality, and aesthetic values that only a healthy Everglades can provide.
