Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) stumps, both healthy and infected by Phellinus weirii (Murr.)Gilbertson, were fumigated with chloropicrin at a clearcut site on Washington s Olympic Peninsula. Vegetation cover on plots adjacent to treated and untreated stumps was evaluated to determine fumigant effects on vascular plants and moss. Ninety-eight vascular...
Previous studies of bird communities in the mid-Willamette Valley, Oregon, indicated that Oregon white oak (Ouercus garryana) stands supported more cavity-using bird
species than sympatric stands of Douglas-fir (Pseudotsuga menziesii). Mature Oregon oak stands are being harvested and few are regenerating. I compared cavity availability for hole-using fauna among 10...
This paper provides a primer on research in the field of public involvement in natural resource decision making. Previous studies are synthesized and organized into three areas: (1 ) goals of public involvement, (2) principles related to implementing public involvement programs, and (3) evaluation of public involvement methods. A bibliography...

There is growing concern among producers regarding the sustainability of current dryland winter wheat cropping practices. This study looks at the economic viability of three wheat rotations currently being studied at the Columbia Basin Research Center in Pendleton, Oregon, including W IF and two alternative rotations, W/B/F and C/W/F. The...
Although many people enjoy deer, these animals can be destructive to gardens, orchards, and landscaped areas. Deer damage to ornamental plants is associated with a variety of factors including increasing numbers of deer, human population shifts to rural and suburban areas, and landowners prohibiting deer hunting.
Satellite altimeter measurements of marine gravity reveal 100 to 200-km
wavelength lineations over a wide area of the Pacific plate oriented roughly in the direction of
absolute plate motion. At least three mechanisms have been proposed for their origin: smallscale
convective rolls aligned in the direction of absolute plate motion...
The Samoan Passage experiment was designed to determine the northward transport of abyssal water through the Samoan Passage (l0°S, 170°W). This topographic constriction forms the major connection for deep (>4000 m) interbasin flow between hemispheres in the Pacific (Figure 1). This report presents current meter data from the six subsurface...
