Excerpt from Forest Insect Conditions in the Intermountain and Northern Rocky Mountain States During 1959 Airplanes were again used in examining forested areas to detect possible new infestations and determine spread in previously discovered centers. Ground surveys were conducted to evaluate the seriousness of outbreaks where air examination or reports from cooperators indicated a need. Infestations on lands of all ownerships are included in this report. Cooperation by Forest Service, Department of the Interior, State, and private personnel contributed greatly to over-all coverage and the success of the program.
