The United States Department of Agriculture uses the Forest Inventory and Analysis (FIA) program to monitor the nation's forests and wood lands, and the National Resources Inventory (NRI) program to monitor the nation's agricultural and range lands. Although their measurement methods and sampling frames are very different, both programs are developing annual systems to better detect trends in land use and ecosystem health, evaluate effectiveness of public policies, guide sustainable development, and forecast alternative future conditions. Other federal programs use Landsat satellite data to map the nation's land cover, land use, and habitat diversity. I offer two proposals that could increase consistency and reduce cost among these federal monitoring programs.
