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.
