Natural resource inventories are extensive, point-in-time efforts to determine the location or condition of resources. Sonoran Desert Network inventories assess and document the current condition and knowledge of natural resources in network parks, providing a solid baseline for long-term monitoring and management.

The national Inventory and Monitoring Program provides guidance, funding, and technical assistance for a set of 12 basic natural resource inventories at all parks with significant natural resources (see table below). These basic inventories are intended to provide park managers with the minimum information needed to effectively manage the natural resources of their parks.
