Abstract

    Assessment of changes in forest canopy health over time by the use of canopy photography. Establish an archivable image of stand condition to use as a baseline for future comparisons. Since a baseline has been created in past years, photography will be taken only if other surveys indicate tree stress or damage is occuring, and results will be compared to baseline established.

      • Canopy photography
        • Started: 1991-06-26
        • Method Description: A canopy photography technique for monitoring stand condition was developed to allow comparisons with forest health survey plots.

      • Photo points
        • Started: 1993-07-01
        • Method Description: 24-25 permanent photo points per forest health plot (North American Maple Project plot and 2 Forest Health Monitoring plots at 1400 and 2200 ft).

      • Camera set up
        • Started: 1991-06-26
