Halibut bycatch management implications for Area 2A and evaluation of an informal video

Creator:: Fruh, Erica
Abstract:: Concern over the incidental catch of non-targeted species in commercial and recreational fisheries has greatly increased. Public attention, negative publicity, controversies between differing fisheries and gear groups and the reauthorization of the Magnuson-Stevens Fishery Conservation and Management Act have led to an increased awareness of the issue. The Pacific halibut...

Strip tillage for high-residue irrigated cropping systems

Creator:: Norberg, O. Steven and Oregon State University. Extension Service
Abstract:: Strip tillage is a conservation tillage system that was developed for row crops grown in heavy, poorly drained cool soils in the northern corn belt states, but which some Pacific Northwest farmers are adapting to their local conditions. This publication provides information on strip tillage compared with conventional tillage, in...

Salmon recovery in the Pacific Northwest : defining what constitutes a wild salmon

Creator:: Courter, Ian I.
Abstract:: In spite of considerable efforts to restore natural runs of anadromous salmonids in the Pacific Northwest, they remain at risk of extirpation. Along with many other factors influencing the decline, stocking from hatcheries over the past hundred years is often suggested to be a major cause. The listing of over...

Assessing the feasibility of policy prescriptions in the Salmon 2100 Project

Creator:: Whitehead, Katharine S.
Abstract:: Wild salmon populations are in decline in the Pacific Northwest. In the region populations and runs of Chinook (Oncorhynchus tshawytsha), Chum (Oncorhynchus keta), Coho (Oncorhynchus kisutch), Sockey (Oncorhynchus nerka), and Steelhead (Oncorhynchus mykiss) have been listed as threatened and/or endangered under the Endangered Species Act (ESA) in the U.S. and/or...

Systematic and reproductive studies of Mimulus (Scrophulariaceae) in the Pacific Northwest : implications for conservation biology

Creator:: Meinke, Robert James
Abstract:: The Mimulus washingtonensis complex is a group of morphologically similar species centered in the Pacific Northwest. All are rare, and most are under consideration for listing as endangered. Morphometric and pollination data were used in developing a revised taxonomy for the group. Five species and two varieties are recognized. Mimulus...

Impacts of forest practices on surface erosion

Creator:: Sidle, Roy C.
Abstract:: Surface erosion can be initiated by forest practices such as timber harvest, road construction, and site preparation. A variety of management and control measures can help reduce this erosion. Surface erosion is generated by soil and operational conditions that are conducive to or cause disturbance and compaction. By using good...

Phylogeography, evolution, and conservation in forest-associated Pacific Northwest salamanders

Creator:: Wagner, R. Steven
Abstract:: Phylogeographic studies of six Pacific Northwest forest-associated salamanders provide insight into historical and contemporary processes on population genetic structure. Among Larch Mountain Salamanders (Plethodon larselli), cytochrome b mitochondrial (mtDNA) sequences (381 bp) and random amplified polymorphic DNA (RAPDs; 34 loci) supported separate Management Units for northern and southern populations (12...

Provenance, lifespan, and phylogeny : testing a conceptual framework for plant community management

Creator:: Benfield, Cara D.
Abstract:: Successful conservation management requires an understanding of how species respond to intervention. Native and exotic species may respond differently to management interventions due to differences arising directly from their native or exotic origin (i.e., provenance) or from differences in life-history or phylogenetic lineage that are associated with provenance. Thus, selection...
