Riparian canopy and channel response to hillslope disturbance in Elk River Basin, southwest Oregon

Creator:: Ryan-Burkett, Sandra E.
Abstract:: 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...

Validation of elk distribution models at Sled Springs Wildlife Demonstration Area, northeast Oregon

Creator:: Coe, Priscilla K.
Abstract:: Landscape models for elk distribution developed at Starkey Experimental Forest and Range from 1993-1995 were tested on another landscape during 2003-2005 at Sled Springs Wildlife Demonstration Area. Using location data obtained from 23 wild elk captured and fitted with GPS telemetry collars, 8 spatial resource selection function models representing 8...

Implications of cougar prey selection and demography on population dynamics of elk in northeast Oregon

Creator:: Clark, Darren A.
Abstract:: Mule deer (Odocoileus hemionus hemionus) and Rocky Mountain elk (Cervus canadensis nelsoni; hereafter elk) populations in northeast Oregon have declined in the past 10 to 20 years. Concurrent with these declines, cougar (Puma concolor) populations have apparently increased, leading to speculation that predation by cougars may be responsible for declining...

Analysis of dredge tailings pile patterns : applications for historical archaeological research

Creator:: Purdy, Sarah E.
Abstract:: For centuries humans have been searching for precious metals. The search for gold has greatly changed the landscape of the American West, beginning in the 1850s and continuing today. Various gold rushes around the country created mining colonies in remote areas, thereby connecting the frontier with the rest of America...

Investigating Calving Areas for Rocky Mountain Elk on the Plumas National Forest: Implications for Land Management

Creator:: Marshall, Abigail C.
Abstract:: Sustainable elk (Cervus canadensis) habitat management on U.S. Forest Service (USFS) lands involves a complex relationship between management practices and ecological processes. A relatively novel Rocky Mountain elk population (Cervus canadensis nelsoni) on the Plumas National Forest (PNF) in northeastern California became established in the early 2000s, but there is...

Rocky Mountain elk (Cervus elaphus nelsoni) behavior and movement in relation to lunar phases

Creator:: Woodside, Gail J.
Abstract:: Two small herds of Rocky Mountain (Cervus elaphus nelsoni) cow elk were, collared, observed, and spatially mapped for 10 continuous six day trials, conducted during 2008-2009. Five trials occurred during full moon periods and five trials during new moon periods. The elk were collared with 1 second interval GPS loggers...

Aspen age structure and stand conditions on elk winter range in the northern Yellowstone ecosystem

Creator:: Larsen, Eric J.
Abstract:: Aerial photographs and field sampling were used to compare aspen (Populus tremuloides) age structure and stand conditions on elk winter range in the northern Yellowstone ecosystem. The elk winter ranges studied were the northern range in Yellowstone National Park (YNP) and the Gallatin National Forest and the Sunlight/Crandall elk winter...

Juvenile survival and birth-site selection of Rocky Mountain elk in northeastern Oregon

Creator:: Rearden, Spencer N.
Abstract:: With declining populations and low calf recruitment in northeastern Oregon, much interest has been generated to study the survival rates and causes of mortality of Rocky Mountain elk (Cervus elaphus nelsoni). I investigated the causes of elk calf mortality and the effects of predation risk on birth-site selection by cow...

Ungulate activity classification : calibrating activity monitor GPS collars for Rocky Mountain elk, mule deer, and cattle

Creator:: Gaylord, Adam J.
Abstract:: Ungulate behavior has been studied extensively but direct observation of free-ranging animals over long periods of time and large geographic areas is often prohibitively difficult. Improved technology, such as GPS collars fitted with motion-sensitive activity monitors, provides researchers with a potential tool to remotely collect fine scale activity and location...

Behavioral responses of Rocky Mountain Elk (Cervus elaphus) to recreational disturbance

Creator:: Naylor, Leslie M.
Abstract:: I measured responses of free-ranging Rocky Mountain elk (Cervus elaphus) to recreational disturbance at Starkey Experimental Forest and Range, Oregon from April to October, 2003 and 2004. Resting, feeding, and travel activities of 13 cow elk were recorded at 5-minute intervals using Actiwatch™ motion sensors. Elk were subjected to four...
