The 5 Worst Invasive Species in the Florida Everglades

As I write in a cover story in TIME this week, invasive species are a growing threat around the U.S. And there's no place quite as thoroughly invaded as Florida:

“We are ground zero for the impacts of invasive species,” says Doria Gordon, director of conservation science for the Florida chapter of the Nature Conservancy (TNC) . “And our invaders are very good at finding new habitats.”

Often those habitats are in or around the Everglades, that vast “river of grass” that covers much of South Florida. Half of the original Everglades has been developed for farming or housing, and the sprawling wetland has been carved up by more than 1,400 miles (2,250 km) of canals and levees that divert water for South Florida’s 5.8 million people. That mix of suburbs and wilderness makes the Everglades an invasive free-for-all.
