Responses of vegetation and sheep to three grazing pressures

Creator:: Thetford, Frank Oren
Abstract:: A study was conducted over a two year period, 1973 through 1974, on perennial ryegrass-subclover pastures with stocking rates of 7.4 (moderate), 9. 9 (heavy), and 12.4 (overstocked) ewes per hectare to establish guidelines on stocking intensity for dryland improved pastures in western Oregon. Climatic conditions varied annually and caused...

Growth characteristics and site potentials of perennial grass species

Creator:: Borman, Michael M.
Abstract:: In this study I assessed the potentials of selected, established perennial grasses to maintain site occupancy in the foothills ecosystem of the Rogue River Valley of southwest Oregon which is currently dominated by a variety of annual plants. The first evaluation compared growth curves of the perennial grasses and contrasted...

Habitat parameters associated with the distribution of seven willow species on a stream in southeastern Oregon

Creator:: Gilbert, Griffith J.
Abstract:: Thirteen different habitat parameters were measured either quantitatively or qualitatively around seven different Salix (willow) species on a defined reach of stream on the southwestern slope of Steens Mountain in southeastern Oregon in order to both broaden the current information base of riparian ecology and inform future willow plantings aimed...

Land-based polyculture of chinook salmon, Oncorhynchus tshawytscha; Manila clams, Tapes japonica (Deshyes); and red macroalgae, Palmaria mollis

Creator:: Moosapanah, G. Reza
Abstract:: This investigation demonstrates the feasibility of a polyculture system using effluent water from land-based salmon culture systems to feed juvenile Manila clams, Tapes japonica (Deshyes), and an evaluation of an artificial diet for feeding juvenile clams. An economic analysis of the polyculture system was compared to cultures of a single...

Revegetation with Carex nebrascensis and Carex utriculata following reconstruction in a NE Oregon meadow stream

Creator:: Quistberg, Sarah E.
Abstract:: Riparian vegetation is an essential component for the maintenance and/or repair of channel stability and function. Sedges within low-gradient riparian systems provide the structure necessary for sediment trapping leading to channel narrowing through bank building processes. Planting success in riparian restoration projects has often failed due to inappropriate species selection,...

The effects of rotational grazing and prescribed burning on bobwhite populations in south Texas

Creator:: Wilson, Marcia H.
Abstract:: Short-term effects of 3 grazing systems and prescribed burning on bobwhite (Colinus virginianus) populations were investigated on the Welder Wildlife Refuge near Corpus Christi, Texas, during spring (April through June) and fall (September through October) of 1976 and 1977. Two rotational systems, high intensity-low frequency (HILF) and four-pasture, deferred-rotation (4PDR),...

Effects of habitat manipulations on California quail in western Oregon

Creator:: Oates, Russell M.
Abstract:: The effects of disking, food plantings, and wheat plantings on a population of California quail (Lophortyx californicus) were studied from fall 1976 to spring 1978 on the E.E. Wilson Wildlife Area, Oregon. Twelve 16.2-ha study sites were established: 3 study sites for each treatment and 3 control sites. Disked areas,...

Effect of site potential, season and plant part on the quality and yield of cereal aftermath

Creator:: Mee, Catherine
Abstract:: The objectives of this study were to evaluate the effects of site potential, season and plant part on percent crude protein, percent digestibility of dry matter and yield of cereal residues. Three cereal types, club wheat (Triticum aestivum) tall, bearded wheat (T. aestivum), and barley Hordeum vulgare) were examined. Stress...

Nutritional ecology of cervids in old-growth forests in Olympic National Park, Washington

Creator:: Leslie, David M.
Abstract:: Nutritional ecology of unhunted and sympatric populations of Roosevelt elk, Cervus elaphus roosevelti, and Columbian black-tailed deer, Odocoileus hemionus columbianus, was investigated in old-growth forests of the Hoh Valley in Olympic National Park, Washington, from September 1979 to November 1981. Seasonal diets of both cervids generally were comprised of common...

Big sagebrush (Artemisia tridentata) ecology and management with emphasis on prescribed burning

Creator:: Champlin, Mark R. (Mark Randolph)
Abstract:: Four studies were conducted. First, mountain big sagebrush communities were burned at Lava Beds National Monument, California, and The Crooked River National Grassland, Oregon. In two years at Lava Beds, basal cover of Idaho fescue in one community and Thur- ber's needlegrass in one of three communities did not recover....
