Invasive Species on Alaska Islands
This website is about introduced animals that occur on Alaska Maritime National Wildlife Refuge. Foxes, rats and livestock were either intentionally stocked or accidentally escaped onto some remote islands. These animals, once established, change the habitat for native wildlife such as seabirds. Non-native predators, such as foxes and rats, can eliminate or greatly reduce nesting birds on the treeless islands. These introduced animals are called invasive species because they were brought to the islands across the natural barrier of the ocean by humans, and invade the habitat of native wildlife.


Restoring Biodiversity
The US Fish and Wildlife Service and its partners are working to restore refuge islands by removing invasive species and preventing their introduction onto more islands. This website describes some invasive species on the refuge and their impact on wildlife.
