The Roosevelt elk (Cervus elephus roosevelti) is a
National Forest management indicator species on the westside
of the Cascade mountains, Western Oregon. A Habitat
Effectiveness model is used by State and Federal agencies to
evaluate elk habitat in the region. Concerns about the
model's lack of differentiation between winter and...
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...
Few studies have evaluated non-migratory Roosevelt elk (Cervus elaphus roosevelti)
interactions and habitat use on lands undergoing extensive timber removal. We captured and
radio-tracked for 14 months representatives from 29 different bands of elk across a 37,000 ha area
of Oregon's Coast Range. We identified 6 habitat variables within individual...
Public agencies need information on the value of
recreational activities to assist in managing fish and
wildlife species. Over the past two decades economists have
developed and applied techniques to measure the value of such
non-marketed commodities.
The contingent valuation method (CVM) is one technique
used by economists to measure...
A wildfire burned over 40,000 ha of conifer and mixed conifer-hardwood forest in
the Silver Creek drainage of southwestern Oregon in the fall of 1987 allowing me to
assess big game use of a large natural burn. I used fecal pellet group counts to estimate
habitat use and effects of...
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...
Conflict over the management of public lands has increased markedly in the recent past. Forest Service personnel are responsible for making decisions about land allocations that are controversial and engender debate. This is a case study examining a conflict over the management of the Elk River drainage on the Siskiyou...
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...
Forage availability, diets, distribution, and productivity were
compared for Roosevelt elk, Cervus elaphus roosevelti, using improved
(i.e. seeded, fertilized, and grazed) and untreated areas of the Oregon
Coast Range. Seasonal forage availability was substantially different
on 1-year-old improved and untreated clearcuts, but the differences
diminished by clearcut age 4 and...
