Evaluation of Spruce Budworm Feeding Damage and Spray Success Using Remote Sensing
Problem Addressed: The evaluation of spray success using color and color infrared aerial photography
Goal(s)/Objective(s): Determine the location and amount of mortality caused by the spruce budworm, detect areas of new budworm attack earlier than with present models, identify forests requiring spraying or other control measures to prevent excessive tree mortality and timber loss from budworm attack more efficiently than with present methodology.

The spruce budworm infestation is continuing in epidemic proportion. The remote sensing--aerial photography project in an effort to provide a better way of monitoring the infestation has, over the past two years, developed techniques where color and color infrared film can be used to identify spruce-fir stands and trees being currently defoliated. Overall tree condition and the location of mortality can also be assessed. A final project on these findings is in preparation.
