The idea of a national park for the Everglades was pitched in 1928, when a Miami land developer named Ernest F. Coe established the Everglades Tropical National Park Association. It had enough support to be declared a national park by Congress in 1934. It took another 13 years to be dedicated on December 6, 1947.[129] One month before the dedication of the park, a former editor from The Miami Herald and freelance writer named Marjory Stoneman Douglas released her first book titled The Everglades: River of Grass. After researching the region for five years, she described the history and ecology of South Florida in great detail. She characterized the Everglades as a river instead of a stagnant swamp.[130] The last chapter was titled "The Eleventh Hour" and warned that the Everglades were dying, although it could be reversed.[131]
