Ecological and silvicultural information on the interaction of gypsy moth and its host forest types is incorporated into silvicultural guidelines for minimizing the impacts of gypsy moth on forest stands threatened by the insect.

Studies of impacts of whole-tree clearcutting in spruce-fir, northern hardwood, and central hardwood forest types are summarized for use by practicing foresters, land managers, environmental protection agencies and organizations, and the general public. Guidelines are given for protecting soils, stream water quality, nutrient cycles, and site productivity.

Twenty papers on the application of spatial analysis to forest insect and disease problems presented at a workshop on spatial analysis and forest pest management.
