Antioch Dunes National Wildlife Refuge

Antioch Dunes National Wildlife Refuge protects what’s left of something irreplaceable: 55 acres of rare inland sand dunes and the endangered species found nowhere else on Earth. Tucked along the San Joaquin River, this tiny refuge proves that size doesn’t determine significance. It’s a last stand for the Lange’s metalmark butterfly and a reminder that conservation happens in unexpected places. Rep the small refuges fighting big battles.
