Book Description
Migratory behavior of Rocky Mountain mule deer (Odocoileus hemionus hemionus) wintering on the east side of the Sierra Nevada, Inyo and Mono counties, was studied from January 1984 to November 1987. Radio-telemetry indicated no differences between years in timing of migration from the winter range, although generally females proceeded males. Upon leaving the winter range, deer moved to spring holding areas on the east slope at higher elevations. There were no year or sex differences in leaving spring holding areas for summer ranges. Summer ranges were mainly on the western slope. Summer home ranges of males were at higher elevations, nearer water, and on steeper slopes than those of females. Fill migration was influenced by snowstorms, particularly in males. Few opportunities for habitat improvement exist on either summer or winter range. Antlerless harvests of deer during periods of population growth can dampen fluctuations in animal numbers caused by variable rainfall.

Book Description
Excerpt from Behavior of Mule Deer on the Keating Winter Range As weather conditions worsen with the onset of winter in eastern Oregon, deer migrate from the forests of the Wallowa Mountains to the surrounding rangelands (fig. Those moving south concentrate on the benchlands near the Powder River (fig. In an area ranging from 1 to 10 miles wide by 40 miles long to 16 km by 64 km), designated here as the Keating Winter Range.

Book Description
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 components or weather conditions, which contribute to differences in habitat use patterns and behavior among wintering populations. We examined winter habitat use by mule deer on the East Front of the Rocky Mountains, Montana and Warm Springs and Sink Creek, east-central Idaho to determine how weather and vegetation affect habitat use in different winter ranges. We used radiotelemetry to locate adult female mule deer and estimated microsite habitat conditions including wind speed, snow depth, percent cover of individual plant species, hiding cover, and canopy cover during winter 2010--2011. We compared data at deer locations to random locations across each study area using logistic regression, developing models based on pooled data for each study area, times of snow accumulation, and times of high wind speeds (for the East Front). We evaluated model fit using a Receiver Operating Characteristic (ROC). Our final models indicated that deer use different habitat components on different winter ranges. On the East Front, a combination of landscape and weather variables predicted probability of deer use of areas. These included percent cover of trees, creeping juniper (Juniperus horizontalis), buffaloberry (Shepherdia canadensis), curly sedge (Carex rupestris), prairie sagewort (Artemisia frigida), whitemargin phlox (Phlox albomarginata), percent slope, snow depth, wind speed, and exposure to wind. These and additional covariates changed in magnitude depending upon weather conditions. Model covariates also changed depending on deer behavior. In Idaho, tall threetip sagebrush (A. tripartita tripartita) and phlox (Phlox spp.) were important predictors of mule deer habitat use, while tall threetip sagebrush and cumulative forbs predicted use of areas under snow conditions. Mule deer habitat use differed between Idaho study areas. In the Warm Springs study area, covariates related to foraging predicted habitat use whereas in Sink Creek, covariates related to thermal or hiding cover predicted habitat use. Differences among all 3 study areas indicate that deer use different habitat components under different winter conditions. Discrepancies among winter ranges are important considerations for habitat requirements of mule deer.
