Introduction
The South Florida Ecosystem Restoration Program is an intergovernmental effort, involving a number of agencies, to reestablish and maintain the ecosystem of south Florida. One element of the restoration effort is the development of a firm scientific basis for resource decision making. The U.S. Geological Survey (USGS), one of the agencies, provides scientific information a part of the South Florida Ecosystem Restoration Program (SFEP). The USGS began their own program, called the South Florida Ecosystem Program, in fiscal year 1995 for the purpose of gathering hydrologic, cartographic, geologic, and biologic data that relate to the mainland of south Florida, Florida Bay, and the Florida Keys and Reef ecosystems.
