The response of soils, streambanks and instream coliform bacteria levels to grazing management in a riparian area

Creator:: Bohn, Carolyn C.
Abstract:: This thesis describes a case study of the effects of five systems of grazing on watershed values in a deteriorated riparian area. Soil infiltration, bulk density and penetrability, streambank edge movement and coliform bacteria were monitored for seven years along a stream in the Blue Mountains of northeastern Oregon. For...

Modeling riparian zone processes : biomass production and grazing

Creator:: Korpela, Edwin J.
Abstract:: Seasonal trends in forage production and environmental parameters for five plant community types within a northeastern Oregon riparian zone were described and modeled using correlation and path analysis. Wet meadows produced the greatest amount of herbage biomass, followed by moist bluegrass meadows, gravel bars, forests and dry bluegrass meadows. Trends...

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...

Influence of leachates from western juniper slash on three native grasses

Creator:: Ramsey, Katherine J.
Abstract:: Paired 30-day trials were conducted to evaluate Agropyron spicatum germination when treated with two concentrations of throughfall leachates from western juniper slash in two stages of decomposition. Data from a second pair of 49-day greenhouse trials were analyzed to evaluate emergence and growth of Aqropyron spicatum, Oryzopsis hymenoides, and Poa...

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...

Cattle grazing habits and movements related to riparian habitats and forested ranges with inference to acute dietary bovine pulmonary emphysema (ADBPE)

Creator:: Roath, Leonard Roy
Abstract:: Grazing on the mountainous forested ranges of the Camp Creek Unit, Malhuer National Forest, was typified by irregular distribution of free-ranging cattle. A combination of management and physical, topographic constraints caused cattle to concentrate on the riparian zone early in the grazing season in 1977 and 1978. A large percentage...

The impact of three stocking intensities and four grazing treatments on the carbohydrate reserves of perennial ryegrass (Lolium perenne L.)

Creator:: El Hassan, Babiker Ahmed, 1940-
Abstract:: A study was conducted during 1974 and 1975 to evaluate the impact of stocking intensity and season of grazing upon carbohydrate concentration, biomass of storage organs, and total carbohydrate per plant in the roots and crowns of perennial ryegrass (Lolium perenne L.) in improved rangelands in Western Oregon. The stocking...

Interactions of cattle and chinook salmon

Creator:: Ballard, Teena M.
Abstract:: Spring chinook salmon spawning occurs in late summer when it is common for cattle to be present in pastures that have streams where fish spawning occurs. This two-year study addressed three main objectives relative to behavioral interactions between cattle and spring chinook salmon during the spawning life history stage. These...

Use of livestock to improve the quality of elk winter range forage in northeastern Oregon

Creator:: Clark, Patrick Eugene
Abstract:: The effects of late spring defoliation on the winter forage quality of bluebunch wheatgrass (Agropyron spicatum [Pursh] Scribn. & Smith), Idaho fescue (Festuca idahoensis Elmer) and elk sedge (Carex geyeri Boott) and the response of wintering Rocky Mountain elk (Cervus elaphus nelsoni Bailey) to changes in winter range forage quality...
