An elk-habitat evaluation procedure for winter ranges in the Blue Mountains of eastern Oregon and Washington is described. The index is based on an interaction of size and spacing of cover and forage areas, roads open to traffic per unit of area, cover quality, and quantity and quality of forage.

The effects on eastside forest ecosystems from long-term grazing by large mammals are assessed, because long-term herbivory can reduce or increase ecosystem productivity. The assessment emphasizes elk and cattle in the Blue Mountains of northeast Oregon and southeast Washington. Histories of…

Existing literature was used to estimate the economic value of elk to hunters and wildlife watchers, and the economic impact on personal income to local communities in the Blue Mountains (Blues) of Oregon and Washington. An annual survey of hunters at the Starkey Experimental Forest and Range…

The Starkey Project, a large-scale, multidisciplinary research venture, began in 1987 in the Starkey Experimental Forest and Range in northeast Oregon. Researchers are studying effects of forest management on interactions and habitat use of mule deer (Odocoileus hemionus hemionus), elk (…

A stand-replacement prescribed fire in an over-mature lodgepole pine (Pinus contorta Dougl. ex Loud.)-subalpine fir (Abies lasiocarpa (Hook.) Nutt.) stand (snag area) and in a mature lodgepole pine thicket (thicket area) resulted in lower plant diversity within the first year…

In the 1980s resource managers were increasingly concerned about effects of timber harvest on ungulates in National Forests. Land and resource management plans incorporated restrictions on timber harvest to maintain cover for Rocky Mountain elk (Cervus elaphus nelsoni V. Bailey…

We researched the environmental attributes (n = 28) associated with elk (n = 50) summer range (1 May ­30 Sep) in the central Black Hills of South Dakota, USA, during 1998-­2001. We defined high-use areas or centers of activity as landscapes underlying large concentrations of elk locations resulting…

Livestock grazing has been considered detrimental to wildlife habitat. Managed gazing programs, however, have the potential to maintain habitat diversity and quality. In cases in which single-species management predominates (sage-grouse [Centrocercus urophasianus] or elk [Cervus…

The effects of vaginal implant transmitters for tissue damage after 11 wk in 13 captive adult elk (Cervus elaphus nelsoni) and subsequent reproductive performance in 38 free-ranging elk were evaluated. Vaginal implant transmitters are designed to be shed at parturition and are used to…

Ponderosa pine ecosystems provide important foraging habitats for both wild and domestic ungulates. Livestock typically graze ponderosa pine ecosystems from May through October. Mule deer and elk may utilize these habitats on a yearlong basis in some areas. Stand density has a significant effect on…
