Manatees come into the harbour in winter. Once a bird rookery, the harbour was cut and bulkheaded for boat access and is now the anchoring heart of Key Biscayne. The surrounding park was Florida's most-visited state park before Hurricane Andrew flattened it in 1992; the Australian pines were replaced with native planting in the rebuild.
