Alaska's Inventory Program

The inventory program provides information for a variety of resources, from bibliographies to species occurrence and distribution. This baseline is used to inform monitoring efforts, long-term management, and stewardship of natural resources in Alaska’s parklands.

Over two-thirds of the land managed by the National Park Service is in Alaska. Because of the vast landscapes, coupled with extreme weather and short field seasons, a regional management approach has been established for base cartography, soils, and landcover inventory programs.
