Forest Health Monitoring

Forest Health Monitoring (FHM) is a national USDA-Forest Service program designed to determine the status, changes, and trends in indicators of forest conditions on an annual basis. The FHM program uses data from ground plots and surveys, aerial surveys, and other biotic and abiotic data sources. It develops analytical approaches to address forest health issues that affect the sustainability of forest ecosystems and produces a variety of useful reports.
