Spring, summer and fall use by cattle and big game on foothill rangelands

Creator:: Miller, Richard F.
Abstract:: The objectives of this study were to evaluate environmental factors influencing use of several plant communities by cattle, elk and deer; determine under story production by plant species and the amount utilized by cattle, elk and deer in certain plant communities; evaluate the interactions of range use between cattle, elk...

Herbage production on three vegetation types in the high desert of eastern Oregon

Creator:: Markgraf, Peter Marion
Abstract:: Objectives of this study were to determine differences in herbage production of three seral stages of three habitat-types. Field studies were conducted in 1967 and 1968 on the Squaw Butte Experimental Range. Twelve, 400-square-foot, paired exclosures were established in each habitat-type. Herbage was clipped from four, 48-squarefoot samples in one...

A model to predict the bacterial quality of a rangeland stream

Creator:: Biskie, Howard A
Abstract:: Grazing cattle usually have access to streams as a source of drinking water. A model was developed for the personal computer to predict the bacterial quality of these streams. The model estimates the number of organisms that enter the stream by the direct deposit of feces and by runoff from...

Rangeland privatization and the Maasai experience : implications for livestock herding, open space, and wildlife conservation in southern Kenya

Creator:: Sundstrom, Shiloh
Abstract:: For centuries in what is now southern Kenya and northern Tanzania, nomadic, Maasai livestock herders have coexisted with vast populations of wildlife. Today, both wildlife and the Maasai herding lifestyle, a vital component of Maasai culture, are threatened by changes to the landscape and losses in mobility, including the policy...

Pacific Northwest rangeland carbon sequestration

Creator:: Wiggins, Seth T.
Abstract:: This paper models the supply curve of carbon sequestration on Pacific Northwest rangelands. Rangeland managers have the ability to sequester carbon in agricultural soils by implementing alternative management practices on their farms. Their low adoption rate in practice suggests a high opportunity cost associated with their implementation. To increase their...

Effects of plant community characteristics on insect abundance : implications for sage-grouse brood-rearing habitat

Creator:: Ersch, Erica A.
Abstract:: A causative factor in declining greater sage-grouse (Centrocercus urophasianus) populations is reduced annual recruitment due to poor habitat quality. Sage-grouse population decline is concurrent with a decline in the extent and quality of the sagebrush (Artemisia sp.) biome. However, current research has shown a positive relationship between sage-grouse brood and...

Development of a legend and key for ecological resource analysis in the 15-mile administrative unit, Malheur County, Oregon

Creator:: Martin, Niels L.
Abstract:: The project of which this research was a part is designed to provide an improved system of ecological resource analysis. Specific objectives of this study were: (1) classification of plant communities on the fringes of the sagebrush steppes and the salt desert of southeastern Oregon, (2) development of symbolic and...

Land use and nonpoint source phosphorus pollution in the Dairy-McKay hydrologic unit area of the Tualatin River Basin, Oregon

Creator:: Wolf, Donald W.
Abstract:: Human activities may contribute to the eutrophication of surface waters by providing nutrients to aquatic ecosystems. Phosphorus is frequently identified as a nutrient that is limiting to most aquatic ecosystems under natural conditions. Sources of phosphorus contributing to eutrophic conditions often include nonpoint sources that are dispersed across the landscape....

Emergency fire rehabilitation of BLM lands in the Great Basin : revegetation & monitoring

Creator:: McArthur, Ted O.
Abstract:: The Bureau of Land Managements (BLM) Emergency Fire Rehabilitation (EFR) policy was developed in 1985 to encourage protection of sites from soil erosion and to minimize potential changes in vegetation communities that may result from the dominance of weedy species. To achieve the goals of EFR policy, managers often used...
