The objectives for year have been the gathering of existing information, initiation of monitoring water quality, evaluation of analytical methods and procedures for measuring nutrient regeneration in the sediment-water interface, and the study of growth-environment correlations in Findley Lake, Chester Morse Reservoir, and Lakes Sammamish and Washington. Progress was made...
Federal legislation requires that governmental programs be evaluated on a wide set of criteria to provide policymakers with information on the achievement or lack of achievement of goals and/or objectives. A methodology to identify and quantify measures of achievement is described. In addition, the methodology is designed to facilitate the...

This nutrient management guide is designed to assist onion growers and crop advisors in producing a high-quality crop while protecting the environment from excess nutrients. Nutrient management strategies recommended here are based on data accumulated over many growing seasons with many different onion varieties in Idaho, Washington, and Oregon. This...
Studies of the effects of climate change on forests have focused on the ability of species to tolerate temperature
and moisture changes and to disperse, but they have ignored the effects of disturbances caused by climate change
(e.g., Ojima et al. 1991).Yet modeling studies indicate the importance of climate effects...
Longitudinal patterns of fish and benthic invertebrate distribution and
habitat use were similar in Thomas Creek, Oregon but clarity of these patterns
differed. I studied fish and aquatic invertebrates simultaneously, at multiple
scales, and used multivariate statistical techniques to compare responses to the
same environmental conditions. Both types of organisms...
