Everglades Facts

DRAINING THE SWAMP

  • Since federal and state officials began draining the Everglades, more than half of the vast river of grass has been developed. Much of the rest has been polluted or distressed.
  • The Everglades, which once encompassed 3 million acres, are now crisscrossed by 2,100 miles of canals and 2,000 miles of levees and berms.
  • As a result, the Everglades has lost more than half of the water that historically flowed from Lake Okeechobee south to Florida Bay.

HARMING AN ECOSYSTEM

  • Florida has listed 113 species of plants as endangered and 47 as threatened in Everglades National Park –- nearly one in four of the preserve’s native plants.
  • Populations of wading birds, such as white ibis and wood storks, have plummeted by an estimated 90 percent.
  • Some 70 species in the region are considered threatened or endangered, including manatees, panthers, and crocodiles.

SLOW, EXPENSIVE RESTORATION EFFORTS 

  • The federal and state governments are spending more than $16 billion to restore much of the historic flow of water to the Everglades.
  • It’s considered the world’s most expensive ecological restoration project. Its costs have more than doubled since it began in 2000.
  • But only six of the planned 68 projects are under construction. At the current pace, it may taken another 100 years to complete the restoration.
  • The goal is to restore about 1.7 billion gallons of water a day that is now diverted to the ocean.
  • When the project is complete, Everglades National Park should receive nearly all the water it did before the land was drained.

IMPACT OF RISING SEAS

  • As sea levels rise, South Florida is among the world’s most vulnerable places.
  • Much of the region is less than 6 feet above sea level; seas are expected to rise by about 7 feet by the end of the century, depending on whether carbon emissions are cut.
  • Many of the region’s eight million people are likely to experience severe flooding. Drinking water, power and sewer systems, and billions of dollars in real estate are threatened.
  • As more saltwater intrudes into the freshwater, the Everglades will be changed irrevocably.
  • Here’s what the latest climate models show is likely to happen to landmarks such as President Donald Trump’s estate, Mar-a-Lago, on Palm Beach in Florida:
