An outbreak of the Douglas-fir tussock moth caused severe defoliation in northeastern Oregon during the period from 1972 to 1974. Aerial application of DOT was used to control the outbreak in 1974. Much of the infected area has been logged to salvage the dead and damaged timber. The purpose of this study was to determine the economic impact of the Douglas-fir tussock moth, the control program and the salvage logging on private recreation businesses in the area of the tussock moth damage. Personal interviews and mailed questionnaires were used to obtain data from the operators of the businesses. Linear regression analysis was done using gross income data from before, during and after the tussock moth infestation to determine if there was a statistical relationship between changes in gross income and the presence of the tussock moth. Business trends in the area affected by the tussock moth were also compared with state park visitation and motel occupancy in all of Oregon. The operators of businesses were questioned about possible reasons for changes in business volume, changes in normal operations as a result of the tussock moth infestation, and visitors actions during the period. Although there was a decrease in business volume during the tussock moth problem there was no evidence to indicate the tussock moth had any appreciable effect on overall business volume or operations in the study area.
Excerpt from Impact of the Douglas-Fir Tussock Moth on Forest Recreation in the Blue Mountains A survey of recreationists, resort owners, packer-guides, motel operators, and employees of natural resource agencies revealed little evidence that a recent outbreak of Douglas-fir tussock moth had significant or widespread influence on recreation in northeastern Oregon.

This text considers forest insects occurring in forest ecosystems, specialized forestry settings, and urban forests, with an approach and coverage that make it suitable for use in both undergraduate and graduate courses in forest entomology and forest protection. Early chapters introduce entomology, middle chapters provide the first comprehensive treatment of the principles of Integrated Pest Management (IPM) of forest insects, and later chapters discuss the pest insects according to their feeding group.
The Interior Northwest Landscape Analysis System (INLAS) links a number of resource, disturbance, and landscape simulations models to examine the interactions of vegetative succession, management, and disturbance with policy goals. The effects of natural disturbance like wildfire, herbivory, forest insects and diseases, as well as specific management actions are included. The outputs from simulations illustrate potential changes in aquatic conditions and terrestrial habitat, potential for wood utilization, and socioeconomic opportunities. The 14 chapters of this document outline the current state of knowledge in each of the areas covered by the INLAS project and describe the objectives and organization of the project. The project explores ways to integrate the effects of natural disturbances and management into planning and policy analyses; illustrate potential conflicts among current policies, natural distrubances, and management activities; and explore the policy, economics, and ecological constraints associated with the application of effective fuel treatments on midscale landscapes in the interior Northwest.
