Evaluation of techniques of monitor wetland hydrology and macroinvertebrate community characteristics

Creator:: Harenda, Mary G.
Abstract:: The lack of cost-effective, reliable sampling methods for many wetland characteristics hinders efforts to describe the structural and functional properties of wetlands. This study evaluated techniques for sampling the subsurface hydrology and invertebrates of freshwater wetlands. The depth of rusting on mild steel rods was compared with water well measurements...

Stream Temperature Modeling for Marys River Watershed

Creator:: Mustafa, Mamoon
Abstract:: High water temperatures in rivers have detrimental effects on riverine water quality and ecology. In this study, two river temperature models, within the agricultural watershed model Soil and Water Assessment Tool (SWAT), were investigated for their ability to simulate water temperatures accurately throughout the year. The original temperature model within...

Invasion by trees into a grassy bald on Marys Peak, Oregon Coast Range

Creator:: Magee, Teresa K.
Abstract:: Grassy balds are meadows that occur on or near the summits of montane peaks and ridges. The sites on which balds are located generally fall within the climatic tolerance ranges of associated tree species. This study evaluates the stability of a forest-meadow transition zone of such a bald on Marys...

Potential of Trichoderma sp. for inhibition of Botrytis cinerea and Sclerotinia sclerotiorum on snap beans

Creator:: Nelson, Mark E.
Abstract:: Isolates of Trichoderma spp. collected from snap bean foliage were tested for inhibition of grey mold of snap beans caused by Botrytis cinerea. In a detached blossom-pod assay an isolate of Trichoderma hamatum reduced pod rot by 94% compared to the nontreated check. Control was comparable to that obtained with...

Soil moisture depletion trends under five plant species present on the Douglas-fir clear-cuts of Mary's Peak, Oregon

Creator:: Drew, Stephen Ernest
Abstract:: Soil moisture depletion trends under five plant species growing on the clear-cuts of the Marys Peak Watershed near Corvallis, Oregon, were followed during the summers of 1963 and 1964. The species were Holcus lanatus, Lotus crassifolius var. subglaber, Gaultheria shallon, Berberis nervosa, and Acer circinatum; and were dominant plants of...

Marys River Watershed restoration planning by using a multiple-objective decision-support tool, RESTORE

Creator:: Nishioka, Kimitake
Abstract:: Effective watershed restoration planning and prioritization is often very difficult because decision making typically involves a large number of alternatives evaluated on the basis of multiple and often conflicting technical, social, economic, and environmental objectives and criteria. In order to solve such complex decision making problems, multiobjective decision making (MODM)...

Geographic Information System (GIS) resource inventories: the Marys River Project

Creator:: Chapman, Shannen S.
Abstract:: The Greenbelt Land Trust (GLT) (a grass-roots conservation group in Oregon) is interested in a conservation plan for the Marys River Corridor. To facilitate this effort, a resource inventory was required and a Geographic Information System (GIS) data base used to compile the inventory (called the Marys River Project (MRP))....
