From the first -- and smallest -- Refuge, created on Florida's 3-acre Pelican Island in 1902, to the 8,900,000 acres of Alaska's Arctic National Wildlife Refuge, our Refuge system is unmatched by any in the world. In areas from Maine to Arizona, millions of pristine acres have been set aside for native wildlife. We explore these Refuges, as well as many of the creatures that inhabit them.
