The old-growth forest conflict is part of the evolving debate over how to use the federal
public lands. This study documents the origins and development of the old-growth issue through
1989. The controversy began in the early 1970s when scientists initiated studies of old-growth
forests and northern spotted owls, and...
While the contemporary movement against sexual and domestic violence has roots in radical, feminist theory and anti-state, community-based modes of resistance, over the past several decades, advocates and activists have increasingly turned to corporations and the state for support through the non-profit, prison, and medical industrial complexes. This acceptance of...
The purpose of this watershed assessment is to provide an inventory and characterization of
watershed conditions in the Wilson River watershed and to provide recommendations that
address the issues of water quality, fisheries and fish habitat, and watershed hydrology.
The migrations, distribution, and feeding of American shad, Alosa
sapidissima (Wilson), were studied from February 1980 through January
1981 in the Columbia River Estuary, an important rearing zone for
young-of-the-year shad. Sampling was performed with purse seine,
beach seine, and otter trawl.
Adult shad and large numbers of juveniles from...
Many studies suggest that weedy plant species are most successful when
soil nitrogen in abundant. Consequently, I used soil nitrogen manipulations to
determine if altering nitrogen would affect the establishment of both weedy and
native plant species in a western Oregon wetland prairie. In two studies, we
added carbon amendments...
Reducing the cover of non-native species is one of the challenges of ecosystem restoration. The goal of this study is to identify native species traits that will increase native species cover and reduce non-native species cover in the first growing season at upland and wetland prairie restoration sites. Native and...
Active habitat management plays a key role in the preservation of native ecosystems and rare species, especially in the Willamette Valley of Oregon, where natural succession to woodlands threatens the few wetland prairies remaining after 150 years of agriculture and urbanization. Sidalcea nelsoniana, listed as threatened under the federal Endangered...
Debris flows are a major cause of disturbance to riparian vegetation. Both observational and experimental studies were used to examine the initial recovery of riparian vegetation after debris flows on headwater streams in the western Cascades of Oregon. My goal was to determine the roles of seedlings and vegetative sprouts,...
