Sheep grazing in Douglas-fir plantations of Oregon's Coast Range and its impact on big game habitat

Creator:: Rhodes, Bruce Douglas
Abstract:: As part of investigations to evaluate the suitability of sheep grazing in Douglas-fir (Pseudotsuga menziesii) plantations of Oregon's Coast Range, this research was designed to evaluate the effectiveness of sheep grazing in suppressing unwanted vegetation, determine seasonal variations in forage quality, and investigate the impact of sheep grazing on big...

Food habits and diet quality of deer and cattle and herbage production of a sagebrush-grassland range

Creator:: Hilken, Thomas O.
Abstract:: Research was conducted on the Keating rangelands in north-eastern Oregon to determine the food habits of deer and cattle and similarity of their diets, and to estimate deer and cattle months of grazing on both a quantitative and nutritional basis. Data were collected during the winters of 1978-1979, 1979-1980 and...

Effect of western juniper removal on ponderosa pine and associated understory vegetation

Creator:: Rose, Jeffrey A.
Abstract:: This research assessed the effect of western juniper (Junlperus occldentalls) removal on understory plant production and cover and ponderosa pine (Pinus ponderosa) growth and plant water status. A complete randomized block design, with four blocks and four treatments was established in the summer of 1984 near Prineville, Oregon. The four...

Identification of restoration potential on southwestern Oregon rangelands

Creator:: Barrington, Mack R.
Abstract:: The objectives of this research were to 1) evaluate the establishment and peak standing crop of Berber Orchardgrass (Dactylis glomerata var. "Berber"), Palestine Orchardgrass (Dactylis glomerata var. "Palestine"), and Sheep Fescue (Festuca ovina var. "Covar") ; 2) to assess establishment and production changes resulting from environmental gradients (elevation, slope, aspect,...

Cattle behavior and distribution on the San Joaquin Experimental Range in the foothills of central California

Creator:: Harris, Norman Rex
Abstract:: Small herds of cows were observed and spatially mapped over continuous twenty-four hour periods. Treatments were implemented that investigated the effect of water site and supplementation on animal distribution patterns. A series of six observation periods constituted each observation series. Observation series were repeated winter (January) and summer (July) for...

Quantification of vegetation diversity and variation on intact and degraded rangelands

Creator:: Dysart, Patricia L.
Abstract:: Vegetation diversity in the Wyoming big sagebrush/Thurber needlegrass (Artemisia tridentata Nutt. ssp. wyomingensis Beetle & Young/Achnatherum thurberianum (Piper) Barkworth. syn. Stipa thurberiana Piper) plant association was studied across a condition class gradient in southeastern Oregon. All observable vascular plant species were counted during 6 seasons and 2 years and diversity...
