Abstract
In attempting to find possible means of combating recurrent epidemics of the spruce budworm in the Northeast, research has shown that forest management has considerable promise. Reduction in the proportion of balsam fir to spruce and attainment of the highest possible proportion of rapidly growing trees are expected to result in a less severe outbreak and a higher percent of recovery following defoliation. These principles of silvicultural control have been discussed in detail by Graham and Orr, Balch, Westveld, and McLintock.
