In short: Indian River County marks the start of Florida’s Treasure Coast, a region defined by its serene beaches and a history tied to a 1715 shipwreck. Beyond the lore of lost gold, the area serves as a vital ecological corridor, protecting diverse estuaries and the nation’s first-ever National Wildlife Refuge.

The identity of Indian River County is deeply rooted in both its maritime history and its unique geography. The name Treasure Coast originates from a 1715 disaster, when a fleet of ships carrying silver and gold was lost to a storm, scattering precious cargo across the seafloor. Today, the region is characterized by a mix of temperate and subtropical climate zones, creating a rich environment for diverse wildlife.

Central to the county’s conservation efforts is the Pelican Island National Wildlife Refuge. Established in 1903 by President Theodore Roosevelt, it holds the distinction of being the first National Wildlife Refuge in the United States. Spanning over 5,400 acres, the refuge provides essential habitat for shorebirds like pelicans and wood storks. Nearby, the Indian River-Malabar to Vero Beach Aquatic Preserve protects 29,000 acres of the Indian River Lagoon, an estuary that serves as a critical nursery for marine life.

The landscape is further defined by its varied ecosystems, ranging from pine flatwoods and sand hills to mangrove forests and maritime hammocks. St. Sebastian River Preserve State Park offers miles of trails for hiking and horseback riding, while Blue Cypress Lake, located at the headwaters of the St. Johns River, features cypress domes and tree islands. These areas are not only recreational hubs for boaters and birdwatchers but also serve as important ecological buffers in a region that remains a focal point for environmental study and preservation.
