Geologic Resources Inventory and Monitoring

The National Park Service (NPS) inventory and monitoring program documents the status and trends of natural resources on park lands. Natural resource inventory and monitoring information is used to assist park managers in decision-making processes and ultimately in resource protection.

The NPS collects data for a set of 12 "basic" natural resource inventories. In the featured programs section, below, information is provided for two of the 12 natural resource inventories, the Geologic Resources Inventory and the Soil Resources Inventory. Information is also provided on geologic resource monitoring in parks. The collection of baseline inventory information on geologic and soil resources and the initiation of long-term monitoring programs to alert management to changes in resource conditions are essential to comprehensive natural resource management.
