When Was Everglades National Park Established?
The Everglades National Park, one of the most iconic and ecologically significant protected areas in the United States, was officially established on December 6, 1947. Located in southern Florida, this unique park was created to preserve the delicate and diverse ecosystem of the Everglades — a vast network of wetlands, mangroves, prairies, and forests that supports a wide variety of plant and animal life.

A Vision for Preservation
The movement to protect the Everglades began in the early 20th century when concerned conservationists and scientists recognized the growing threats to the region due to drainage projects, agricultural expansion, and urban development. Unlike many other national parks that were established for their scenic landscapes or geological formations, Everglades National Park was groundbreaking in that it was the first national park created to protect a fragile ecosystem for its biological value.
Much of the early advocacy came from individuals like Marjory Stoneman Douglas, whose book “The Everglades: River of Grass”, published in 1947, played a pivotal role in raising public awareness about the ecological importance of the area. Her efforts, along with those of other activists and scientists, helped shift public perception of the Everglades from a worthless swamp to a vital and irreplaceable habitat.
Official Designation
In 1934, Congress authorized the creation of Everglades National Park, but it took over a decade of land acquisition, funding, and public support before the park could be officially established. On December 6, 1947, President Harry S. Truman dedicated the park in a ceremony held at Everglades City, Florida. During his speech, he emphasized the need to protect this “unique and priceless wilderness” for future generations.

Legacy and Importance
Today, Everglades National Park spans over 1.5 million acres, making it the third-largest national park in the lower 48 states. It is home to rare and endangered species such as the Florida panther, American crocodile, and the West Indian manatee. The park also serves as a critical water resource for the region and plays a vital role in flood control and climate regulation.
Everglades National Park has been recognized as a World Heritage Site, a Wetland of International Importance, and an International Biosphere Reserve, underscoring its global ecological significance.
Conclusion
The establishment of Everglades National Park on December 6, 1947, marked a turning point in the conservation movement in the United States. It was a pioneering effort to protect an ecosystem not just for its beauty, but for its environmental importance. Today, the park stands as a testament to the power of public advocacy, scientific understanding, and the enduring value of natural preservation.
