The protected areas of Puerto Rico include an array of natural areas in the archipelago of Puerto Rico, an unincorporated territory of the United States, managed by a number of agencies and entities belonging to both federal and commonwealth government bodies. Although Puerto Rico has no natural units in the National Park System, the biodiversity of the island is recognized and protected through a national forest, a national wildlife refuge, a national wilderness, and numerous state parks (called national parks in Puerto Rico), nature reserves, state forests, wildlife preserves and other designations on state, municipal and public-private administration levels.
