Daily and seasonal habitat use by Roosevelt elk was investigated
in the Oregon Coast Range on managed, public forestland. Over 3,700
locations of 6 radio-collared cow elk were recorded during 12 consecutive
months. Two elk formed part of a north band and 4 elk were
part of a south band....
Seasonal movements, home ranges, core areas and habitat use patterns of hunted, migratory Roosevelt elk (Cervus elaphus roosevelti) were investigated on the Olympic Peninsula, Washington. Radio telemetry was used to obtain more than 3,100 locations of 9 elk from May 1984 - March 1985, and November - December, 1985. Radio-collared...
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...
Seasonal movements, habitat use, home range selection, and
group interactions of Roosevelt elk (Cervus elaphus roosevelti)
were studied in the upper White River watershed in west-central
Washington. Over 2000 locations of 14 elk were recorded by
radio-telemetry from April 1983 to December 1984.
During winter, two herds used clearcut lands...
Elk River is a sixth order stream, draining a 200 square
kilometer basin in the Klainath Mountain province of
southwestern Oregon. Timber harvesting began in the basin
during the 1950's, with peak removal of wood occurring in the
mid to late 1960's. This activity lead to an increase in the...
This research provides information on the distribution of an
unexploited Roosevelt elk population in unaltered habitat in Olympic
National Park. Radio-telemetry was used to document home range and
habitat use by 11 adult cow elk in the Hoh Valley during March 1978,
from 10 June-15 September 1978, and from 1...
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...
Includes a brief report of a survey of the Yaquina River to the head of tide, including part of the Big Elk River up to Sunset Quarry. Concludes that the river is "sufficiently navigable to meet all demands of commerce," (p.2) and does not recommend any improvements.
