Culebra NWR

The refuge has diverse habitats including sub-tropical dry forests, mangroves, brush, grasslands and 22 small islands. The small rocky cays serve as temporary home to 13 species of nesting seabirds. The larger cays consist of sub-tropical dry forest habitats. The largest refuge seabird colony is on Peninsula Flamenco where 60,000 Sooty Terns nest. The Mt. Resaca Unit, on the main island of Culebra, is the largest remaining forest on the island and has rock strewn canyons and ravines forming a unique habitat known as the boulder forest. This area contains species characteristic of more humid areas. Three sea turtle speices (leatherback, hawksbill and green) utilize waters surrounding the refuge. Leatherbacks and hawksbills nest on refuge beaches. Two mangrove units help protect the vital link between terrestrial and marine ecosystems. The Ensenada Honda Unit has mainly red mangroves and is the largest mangrove tract in the archipelago.

The refuge office is in Lower Camp, a short drive from Culebra airport.
