Evaluation Monitoring

Evaluation Monitoring of Swiss Needle Cast in Oregon. Aerial detection survey results differ from year to year because symptoms change rapidly in response to weather conditions before and during the flight period (mid-April through May). Surveys flown later (close to the time of budburst) usually detect more areas with symptoms than those conducted earlier.

The Evaluation Monitoring (EM) component of the Forest Health Monitoring program is designed to determine the extent, severity, and causes of undesirable changes in forest health identified through Detection Monitoring (DM) and other means. The need for EM projects arises when significant forest health changes or trends are found in DM. EM also provides additional information about forest health improvements such as improved plant vigor resulting from air pollution abatement.

Biological evaluations usually produced by Forest Health Protection (FHP) focus on the effects of insect and disease infestations and other forest disturbances. Although these surveys and reports serve well to detect and quantify the severity and extent of the disturbance, FHM focuses on the long-term, widespread, unexpected, and sometimes subtle changes resulting from the disturbance. EM provides the first follow-up to changes and trends of forest health concern due to the biotic and abiotic disturbance agents.

Projects funded through EM delve into the extent, severity, and/or causes of forest health problems. Project proposals are submitted through the FHM Regional Managers and selected through regional and national competition, considering the criteria detailed in EM Proposal Instructions (below).
