Refuge Facts

Natural History

  • The salt flats area is catalogued as a category 1 resource by the National Fish and Wildlife Service, meaning that the area is unique and irreplaceable both at national and regional levels.
  • The refuge lies along the coastal plain of southwestern Puerto Rico. This land had been in agricultural use for at least two centuries prior to Service ownership. Heavy grazing left the area barren except for a limited number of trees in drainage's and near homesteads.

The U.S. Fish and Wildlife Service's mission is, working with others, to conserve, protect and enhance fish, wildlife, and plants and their habitats for the continuing benefit of the American people. We are the only agency of the U.S. Government with that primary mission. The Service helps protect a healthy environment for people, fish and wildlife, and helps Americans conserve and enjoy the outdoors and our living treasures. The Service's major responsibilities are for migratory birds, endangered species, certain marine mammals, and freshwater and anadromous fish.
