    Description

    Thorough evaluation of insect impact on forest stands is difficult and expensive on the ground. In a study of tree damage following Douglas-fir tussock moth defoliation in Modoc County, California, large-scale (1:1,584)70-mm. color aerial photography was an effective sampling tool and took lesstime and expense than ground methods. Comparison of the photo interpretations with a sample ground cruisegave high correlations (0.78 to 0.095) for tree mortality top kill, and an estimate of mortality made from photoswas within 5 cut of the ground cruise estimate.
