Everglades National Park was established in 1947 to preserve the biological features and essential primitive conditions of the subtropical Everglades of Florida. It is the largest U.S. national park east of the Rocky Mountains. It is also recognized as the most threatened, due primarily to hydrological developments that have disrupted water flow with serious ecological consequences.
The Park receives more than a million visitors annually, and contributes $120 million each year to the local economy through tourism revenue. The outstanding significance of the Park is recognized by the international community through its designation as a World Heritage Site, a Wetland of International Significance, and a Biosphere Reserve under UNESCO. Approximately 25% of the Park's visitors are international travelers.
