Biscayne National Park protects the larger portion of south Florida's Biscayne Bay, a uniquely tropical lagoon harboring crocodiles, manatees, dolphins, and Caribbean fish. Tropical trees cover its islands, while the world's fourth-longest coral reef sits offshore. Native Americans lived here thousands of years ago; the Spanish held it for 200 years. Hundreds of ships foundered on the reef, fueling a lucrative wrecking industry. In the late 1800s, hardy homesteaders created an agricultural and fishing community. In the 1920s and 1930s, it became a playground for the newly rich and famous. Bracketed by Miami and Key Biscayne to the north and Key Largo to the south, the nearby population eventually grew to over 2. 5 million residents and over 14 million annual visitors. To protect these unique natural and historical resources and to assure its enjoyment by future generations, a half century ago, the federal government created Biscayne National Monument, which later became Biscayne National Park.
