Florida Everglades

Everglades Ecosystem Assessment: Water Management and Quality, Eutrophication, Mercury Contamination, Soils and Habitat - EPA 904-R-07-001, August 2007

The United States Environmental Protection Agency’s Everglades Ecosystem Assessment Program is a long-term research, monitoring and assessment effort. Its goal is to provide critical, timely, scientific information needed for management decisions on the Everglades ecosystem and its restoration. Since 1993, three phases of marsh sampling and one phase of canal sampling have been conducted throughout the Everglades at over 1000 different locations. The Program is unique to South Florida in that it combines several key aspects of scientific study: a probability-based sampling design, which permits quantitative statements across space about the condition of the ecosystem; a multi-media aspect; and extensive spatial coverage.
