Everglades A unique region of wetlands in southern Florida where a shallow ground with sawgrass is covered in water 4,000 square miles

Why are the Everglades Important?
Provide habitats for many rare or endangered species Waste materials can be absorbed by plants Natural water filters Help control floods by absorbing extra runoff from heavy rains
11
Why are the Everglades in Danger?
Agriculture –farming has accidentally leeched chemicals into the slow-moving waters of the marsh, upsetting the balance of nutrients Development –wetlands have been filled in for farming Introduction of invasive species to the environment Water that once flowed into the Everglades from other sources has been diverted for farming and household use
