The Resource Monitoring and Assessment (RMA) program mission is to improve forest and range ecosystems by developing and applying inventory and monitoring methodology to maintain current comprehensive inventories and conduct multiscale assessments of the status, trends, and future outlook for Pacific Northwest ecosystems.

The RMA Program conducts research on forests throughout the world, as well as inventories forest resources in Alaska, California, Hawaii, Oregon, Washington, and U.S.-affiliated Pacific Islands. Our research and monitoring efforts provide the public, land managers, and policy makers with timely, reliable, data-driven science to inform land-use and management decisions.

The inventory and monitoring component of RMA is part of a larger, national Forest Inventory and Analysis(FIA) program. The FIA program provides data and basic resource information needed to assess the current status and potential futures of America's forests.
