The diverse geological formations found within the national monument's fragile coastal ecosystem provide feeding and nesting grounds for many sea birds, including gulls, bald eagles, peregrine falcons, pigeon guillemots, common murres and cormorants. Two threatened species, southern sea otters and Steller sea lions, as well as California sea lions and Guadalupe fur seals are examples of marine mammals that find shelter and breeding habitats within the monument's boundaries. For such birds as brown pelicans, a threatened species, the monument serves as a roosting ground.
Visitor centers for the offshore sanctuaries are being established along the California coast in conjunction with existing marine conservation organizations. The first to open, the Coastal Discovery Center at William Randolph Hearst Memorial State Beach in San Simeon, has interactive exhibits that provide information about the ocean environment. For additional information phone (831) 582-2200 or (805) 927-6575 for the Coastal Discovery Center.
