The rivers of Florida vary widely in their geographical characteristics, ranging from subtropical to moderate climate ecosystems. With the drastic population increase in this state, many river habitats are threatened by destruction, be it through housing development, excessive drainage for drinking water, or contamination. The diverse river systems in question, many of them unique yet highly applicable as case studies for the other parts of the country, are examined from several angles, including geography, vegetation, fisheries, response to physical modification, and ecological stability. Written with the ecologist as well as the environmental practitioner and policymaker in mind, it attempts to arrive at scientifically-based suggestions for river management and preservation. Its publication is especially timely in light of the widespread public concern over the issue and accompanying media coverage.
