Book excerpt: Excerpt from Radial Growth of Grand Fir and Douglas-Fir 10 Years After Defoliation by the Douglas-Fir Tussock Moth in the Blue Mountains Outbreak More than 300 1/50th-acre plots were established in conjunction with 22 tussock moth population study areas (mason 1976) in the Blue Mountains to study the ef fects of defoliation (wickman 1978a). The area consisted of a 100-km transect of a tussock moth outbreak on the Umatilla and wallowa-whitman National Forests and included four additional, severely defoliated areas not included in the population study. Defoliation of each plot tree was estimated in seven classes immediately after the year of most intense defoliation (1972 or Defoliation classes were based on the percentage of crown length totally defoliated, as described in Wick man (1978a).

Book excerpt: 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.
