The primary purpose of natural resource inventories is to document the presence, condition and knowledge of natural resources in the parks. Inventories establish a solid baseline for making scientifically sound management decisions and for designing long-term monitoring plans that track the health of key park resources.

The NPS Inventory and Monitoring Program developed a strategy for a set of products for 12 “basic” natural resource inventories that were common to all park units containing significant natural resources.
