Green Cay National Wildlife Refuge

Green Cay National Wildlife Refuge is a small protected island north of Saint Croix in the United States Virgin Islands, administered as part of the Caribbean Islands National Wildlife complex. Though only about 6 hectares, or 14 acres, it holds the largest remaining population of the endangered Saint Croix ground lizard, which vanished from Saint Croix after the introduction of the small Indian mongoose. Smaller groups persist on nearby Protestant Cay and Ruth Island, making Green Cay a vital refuge for the species. In 2008, lizards from Green Cay were moved to Buck Island for reintroduction. The island also supports important birdlife and, with Southgate Coastal Reserve, is recognized as an Important Bird Area.
