The USDA Forest Service, Forest Health Monitoring (FHM) is a national program designed to determine the status, changes, and trends in indicators of forest condition on an annual basis.

The FHM program in Region 5 uses data from ground plots and surveys, aerial surveys, satellite imagery and other biotic and abiotic data sources and develops analytical approaches to address forest health issues that affect the sustainability of forest ecosystems.

Region 5 Forest Health Monitoring Programs:

  • Aerial Detection Monitoring

    Find information and data from the Region 5 aerial detection program, which detects, maps and monitors current year mortality and other forest damage.
    Aerial Surveys

  • Evaluation Monitoring

    Learn more about this grant opportunity to determine the extent, severity, and causes of undesirable changes in forest health identified through detection monitoring (DM), including ground plots and surveys, aerial surveys, and other data sources.

  • Sudden Oak Death (SOD) Monitoring

    The USDA Forest Service supports monitoring for the distribution of SOD by several entities. The Dave Rizzo Lab at UC Davis monitors the distribution of SOD in all coastal watersheds and the Matteo Garbelotto Lab at UC Berkeley works with UC Extension Units and the counties they serve to determine the distribution of the disease.
