Vegetation changes of communities containing medusahead (Taeniatherum asperum (Sim.) Nevski) following herbicide, grazing, and mowing treatments

Creator:: Turner, Robert Bruce
Abstract:: Studies were conducted from 1962 to 1966 to investigate the effectiveness of several practices in manipulating medusahead (Taeniatherum asperum (Sim. ) Nevski) infested and/or dominated ecosystems by releasing competition in favor of perennial grasses. Several herbicide treatments were evaluated for selective control of medusahead and cheatgrass (Bromus tectorum L. )...

Methodology for cuticular identification of selected eastern Oregon range plants

Creator:: Schrumpf, Barry J.
Abstract:: Animal dietary preferences have been studied by feeding-site examinations, animal observation, and stomach and esophageal collections. Analysis of fecal material for undigested plant cuticle is another means for obtaining the same information. This study was conducted to: (1) prepare a microscope slide series depicting the surface features of leaves and...

Fabrication and characterization of p-type CuO / n-type ZnO heterostructure gas sensors prepared by sol-gel processing techniques

Creator:: Ravichandran, Ram
Abstract:: Increased interest in the field of sensor technology stems from the availability of an inexpensive and robust sensor to detect and quantify the presence of a specific gas. Bulk p-CuO/n-ZnO heterocontact based gas sensors have been shown to exhibit the necessary sensitivity and selectivity characteristics, however, low interfacial CuO/ZnO contact...

Forage production on range sites in east central Malheur County, Oregon

Creator:: Bunch, Thomas R
Abstract:: Objectives of this investigation were two-fold: (l) to determine crested wheatgrass production on selected range sites and (2) to evaluate present and potential production on public and private lands in the study area. Field studies were carried out in 1953 and 1964 near Jordan Valley, Malheur County, Oregon, on the...

Vegetation and animal responses to grazing crested wheatgrass at three intensities and two seasons in southern Idaho

Creator:: Sharp, Lee Ajax
Abstract:: Land useable for livestock grazing in the western United States is diminishing because of spreading municipalities, irrigation developments, highway construction, recreational demands and withdrawals. Concurrently, the demand for livestock and livestock products is increasing because of a rapidly growing population. As a result, production from the grazing land that remains...

Evaluation of dry-weight-rank and microscopic point techniques for seasonal botanical analysis of two pasture mixtures

Creator:: Bauer, Welby
Abstract:: This study was undertaken to evaluate the dry-weight-rank and microscopic point methods for determining botanical composition on perennial ryegrass (Lolium perenne L.) - subclover (Trifolium subterraneum L.) and tall fescue (Festuca arundinacea Schreb.) - subclover pasture mixtures throughout a grazing season. Botanical composition was determined on a monthly basis from...

Forest associations and secondary plant succession in the southern Oregon coastal range

Creator:: Bailey, Arthur Wesley, 1938-
Abstract:: Forest associations, secondary succession, and relationships of plant communities to Roosevelt elk were investigated. Stratification of vegetation into ecological units and an understanding of secondary succession by habitat-type were a necessary first step in investigations into browsing of conifers by elk. The study was jointly conducted by the Oregon State...
