Tracking Rapid Change in the Arctic

The Arctic Inventory & Monitoring Network consists of five parks in northern Alaska: Bering Land Bridge National Preserve, Cape Krusenstern National Monument, Gates of the Arctic National Park and Preserve, Kobuk Valley National Park, and Noatak National Preserve. They are the farthest-north and only Arctic parks in the National Park System.

We collect information on plants, animals, water, and climate to understand how Arctic ecosystems function and are changing over time. This science informs the decisions park managers make to improve the stewardship of the natural resources and ensure their conservation for future generations.
