Evaluation of Cattle Use of A Deer Winter Range in the Black Hills
Cattle use of a deer winter range in the Black Hills was investigated during the summer grazing seasons of 1971-1972. A U.S. Forest Service grazing allotment situated between Mystic and Redfern, South Dakota, was used as the study area. The allotment was divided into five grazing units or pastures …

Riparian willow dynamics and their interaction with environmental and biological factors in the elk winter range of Rocky Mountain National Park (Colorado) - a multi-scale analysis
… factors were evaluated in two valleys of the elk winter range of Rocky Mountain National Park (Colorado). Studies at the individual, population, and landscape scale were conducted, and results from these studies were incorporated into a spatial, process based model (SAVANNA). Morphological and …

Effect of enhanced nutrition during winter on the Uncompahgre Plateau mule deer population
… edulis) and juniper (Juniperus osteosperma) winter range was the primary cause of the observed decline. In contrast, many of the Colorado Division of Wildlife’s (CDOW) constituents hypothesized that high predation rates were keeping the mule deer herd below nutritional carrying capacity. …

Trade-off analysis of accuracy and spatial resolution in strategic forest planning models
… (area of natural disturbance type and ungulate winter range) and outputs (harvest volume, growing stock and seral stage distribution). In general, deviations in all criteria increased with the block size. Spatial resolution was also evaluated by the database size and simulation runtime. A …

Conserving Montana's sagebrush highway: long distance migration in sage-grouse
… migration, a 240-km journey between summer range in north central Montana, USA, and Saskatchewan, Canada, to winter range north of the Missouri River. We learned more about grouse migration by asking: Do birds fly quickly through a corridor, or do they use stopover habitats within a larger …

Mule Deer Responses to a Pinyon-Juniper Removal
… a pinyon-juniper removal treatment on mule deer winter range in the Toiyabe Range of central Nevada to assess changes in resource selection and diet diversity of mule deer following the treatment. The pinyon-juniper removal treatment was conducted in autumn of 2018. We captured 36 adult female …

Habitat Selection and Sexual Suggestion of Rocky Mountain Bighorn Sheep in Custer State Park, South Dakota
… the sexes congregate on a traditional breeding range (cf. Geist 1971, p 209). These studies also have shown that the sexes remain separated during the winter, when segregation should be least likely. During winter, resources, particularly forage, are most limiting and when the sexes would be …

Winter habitat use by mule deer in Idaho and Montana
Winter survival for species such as Rocky Mountain mule deer (Odocoileus hemionus hemionus) depends on an energy conservation strategy where they use habitats at lower elevations and on south facing slopes with adequate thermal or canopy cover. However, not all mule deer habitats are equivalent in …
