Ecosystem Management Principles Much attention is currently fo- cused on the South Florida ecosystem by policy makers, scientists, and natural resource man- agers at all levels. Activi- ties include a White House ecosystem management initiative, a federal inter- agency task force, a Governor's commission, and many agency pro- grams at federal, state, and local levels. Ecosystem management is emerging as an innovative framework for achieving harmonious and mutually dependent sustainability of society and the environ- ment. Ecosystem manage- ment focuses on human and natural systems at regional scales across intergenerational time periods. South Rorida Vision The Greater Everglades ecosystem is a unique regional and national resource of global significance whose continued existence is severely threaten- ed. Our vision is to recover and sustain a healthy South Florida ecosystem including a diverse human culture and its social and economic needs. The ecosystem manage- ment principles crystal- lized at Isle au Haut reflect currently developing con- cepts and the relevant sci- entific literature. These re- sulting principles must be considered as an integrated whole.
