The Everglades is a unique and vast wetland ecosystem located in the southern portion of the U.S. state of Florida. It is a subtropical wilderness that covers approximately 1.5 million acres of land, including sawgrass marshes, mangrove forests, cypress swamps, and estuarine habitats. The Everglades is home to a diverse range of plant and animal species, many of which are found nowhere else on Earth. It is also an important source of freshwater, providing water to millions of people in southern Florida. The Everglades National Park was established in 1947 to protect this remarkable ecosystem, which is now recognized as a UNESCO World Heritage site.
