Central Alaska Network natural resource inventories are extensive, point-in-time efforts to determine the location or condition of resources. Alaska’s Inventories assess and document the current condition and knowledge of natural resources in Alaska’s parks, providing a solid baseline for long-term monitoring and management.
The national Inventory and Monitoring Division provides guidance, funding, and technical assistance for a set of 12 basic natural resource inventories at all parks with significant natural resources. These basic inventories are intended to provide park managers with the minimum information needed to effectively manage the natural resources of their parks.
Approximately one quarter (4.6 million acres) of Alaska's glaciers exist within national parks. Glaciers require three conditions to form: abundant snowfall, cool summers, and the gravitational flow of ice. They form in land areas where annual snowfall is greater than annual snowmelt.
