This is the 14th report in a revised format of national annual reports of the Forest Insect and Disease Survey which date back to 1936. It describes, under the title "Major Insects Pests" those pests considered to be currently significant in terms of their present or potential economic, sociological, or environmental impact. Pests described under "Insects and Diseases of Regional Importance" are particularly significant in one or two regions but have little national impact. Surveys designed to assess forest health are described under "Monitoring, Declines and other Damage." Special surveys done in some regions to address pest problems in nurseries, seed orchards, and young plantations are included. The status of many other pests is presented in tabular form by region in the Appendix entitled "Other Insects, Disesases and Damage." Although they usually do not have spectacular effects, they are important because of their potential for expansion, consideration of quarantine, and their possible role as vectors and as indicators of other problems.
