Green Cay National Wildlife Refuge
Green Cay National Wildlife Refuge, just north of Saint Croix, U.S. Virgin Islands, preserves habitat for the largest remaining population of endangered Saint Croix ground lizard. Much smaller populations of ground lizard live on nearby Protestant Cay and on Ruth Island. Its extirpation from the mainland of St. Croix is generally attributed to the introduction of the small Indian mongoose. In 2008, the National Park Service reintroduce the lizard to Buck Island, translocating 57 individuals from Green Cay.
The 14-acre Green Cay is midway between the town of Christiansted and Buck Island Reef National Monument.
Green Cay NWR is administered as part of the Caribbean Islands National Wildlife complex.
There is a smaller "Green Cay" off the coast of St. Thomas.
