Everglades National Park protects the largest subtropical wilderness in the United States with more than 1.5 million acres of sawgrass prairies, pine rocklands, hardwood forest, and mangrove estuary leading to Florida Bay and the Gulf of Mexico. Established in 1947 as the first national park created for its biodiversity, Everglades National Park is home to many critically threatened and endangered species including the Florida panther, the American crocodile and the West Indian manatee. The park is also the main source of drinking water for residents of South Florida. Learn more at Everglades National Park and on Facebook, Twitter, Instagram, and Flickr.
