Great White Heron National Wildlife Refuge

The Great White Heron National Wildlife Refuge spreads across the Florida Keys, comprising mangrove-covered islands, shallow water channels, and small cays. The area mixes land and water habitats that support diverse bird populations, marine life, and coastal ecosystems.

The refuge was created in 1938 to protect the great white heron and other bird species from extinction. Its establishment was an early effort to safeguard the unique ecosystems of the Florida Keys.

The refuge is named for the great white heron species that makes its home here. Visitors can observe these birds fishing and nesting in the mangrove trees from various vantage points across the islands.

Exploring the refuge requires a boat, as visitors travel by water to reach the islands and observe wildlife. The best visiting season is during cooler months, when conditions are more comfortable and animals are more active.

The refuge is home to rare butterfly species such as the Miami blue, found in only a few Florida locations. The mangrove islands provide these delicate insects with protected space to thrive and reproduce.
