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...
This research was conducted on three study areas on elk winter
ranges in Northeast Oregon. One was on the Starkey Experimental
Forest and Range and the others were in the same vicinity. Plant
appendages, spring and fall defoliation and fall growth of bluebunch
wheatgrass were evaluated in terms of quality...
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...
Research was conducted near the Starkey Experimental Forest and Range in
northeastern Oregon. Effects of defoliating bluebunch wheatgrass (Agropyron
spicatum (Pursh) Scribn. and Smith) to increase the quality of regrowth available on
elk (Cervus elaphus nelsoni) winter range were studied from 1988 through 1990.
Clipping treatments were implemented to condition...
Esophageal fistulation, stomach content analysis, fecal analysis,
and ocular-estimate-by-plot are four of the most publicized methods
of determining the diets of large herbivores. The principal objective
of this study was to compare the relative values of each of these
methods based upon information collected from bi-fistulated (esophageal
and rumen) sheep...
The objectives of this study were to determine the diets of
cattle at risk to DABPE on stress and inciting pastures and to determine
if segregated feeding groups of cattle displayed differential
susceptibility to DABPE.
Stress pastures were classified and mapped by plant communities
and segregated feeding group areas. Cattle...
