1.5 million acres in southern Florida, dubbed Everglades National Park in 1947, were inscribed by UNESCO in 1979, and then inscribed to UNESCO’s List of World Heritage Sites in Danger in 2010. The national park protects only the southern 20% of the original Everglades, yet it is the third largest national park in the lower 48 states after Death Valley and Yellowstone. Everglades National Park is also an international treasure as one of only three locations on the globe to appear on the three big lists: World Heritage Site, International Biosphere Reserve, and Wetland of International Importance. The diversity here of wildlife, nine Everglades ecosystems and changing habitats might blow your mind. The national park protects 800 species of land and water vertebrates, over 400 bird species, more than 275 species of fish and over 20 species of snakes. Here is a look at the wild beauty of America’s Everglades. [34 Photos]
