  • Roosevelt elk habitat use in the Oregon Coast Range

    Creator:
    Pope, Michael D. (Michael Dickens)
    Abstract:
    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...

  • Factors affecting habitat use by black-tailed deer and Roosevelt elk in the Silver Burn, Southwestern Oregon

    Creator:
    Michalski, Bret L.
    Abstract:
    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...

    Friesen, Cheryl Ann
    Abstract:
    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...

  • The effects of forage improvement practices on Roosevelt elk in the Oregon Coast Range

    Creator:
    Stussy, Rosemary J.
    Abstract:
    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...

  • Influence of limited access roads on Roosevelt elk in the Oregon Coast Range

    Creator:
    Cole, Eric K.
    Abstract:
    No studies have evaluated the effects of limited vehicle access on movements, survival and habitat use of Roosevelt elk (Cervus elaphus roosevelti) . We installed twenty gates, restricting motorized vehicle access by the public in seven discrete Road Management Areas (RMAs), comprising 35% of the study area. We radio-tracked 31...

  • 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...
