Methods to assess factors that influence grass seed yield

Creator:: Louhaichi, Mounir
Abstract:: A greater than 10-fold increase in Canada goose (Branta canadensis) populations over the past several years has resulted in concerns over grazing impacts on grass seed production in the mid-Willamette Valley, Oregon. This study was designed to develop methods to quantify and statistically analyze goose-grazing impacts on seed yields of...

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....

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...

Sediment potentials for selected ecological land units in central Oregon

Creator:: Mattison, Jeffrey L.
Abstract:: During the summers of 1975 and 1976 a sedimentation study was conducted in the Bear Creek watershed, located in the southeastern corner of Crook County, in central Oregon. The Rocky Mountain infiltrometer was used to simulate high intensity rainfall over 468 sedimentation plots. Rainfall and runoff were measured and a...

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...

Plant communities and habitat types of the Meadow Creek experimental watershed

Creator:: Ganskopp, David C. (David Conrad)
Abstract:: The objectives of this study were: 1) to identify and map the experimental area of Meadow Creek watershed by existing vegetation, and 2) to identify and map the experimental area of Meadow Creek watershed by habitat types. The classification system adopted for this study was based on the habitat type...
