. Ecology of sympatric populations of mule deer and white-tailed deer in a prairie environment . 3412341 23412 July August September October WEEK AND MONTH Fig. 15. Alfalfa field use by mule deer and white-tailed deer on the Cherry Creek area during July-October, 1983 and 1984. Data are percent of total deer counted in the drainage during autumn aerial survey that were observed during weekly spotlight counts. similar to those occupied by yearlong residents. Cells used by autumn migrants during summer contained significantly less badlands area and edge than those used by the resident segment (Table 15). However, they were more mesic than those occupied by the summer migrants in that they contained greater area of badlands, greater area and edge of hardwood draws, less area of mixed prairie, and less edge of mesic shrubland. Although differences in habitat characteristics between areas used by autumn migrants and resident deer were minor, they did influence some differences in habitat use. Cells used by autumn migrants during summer contained greater area of sagebrush grassland and less edge of bunchgrass prairie than cells used during winter (Table 16). Thus, autumn migrants, like summer migrants, may have compensated for reduced area of badlands or other habitat deficiencies within their home ranges by using a greater variety of habitats to meet their resource needs. It was only during late summer and autumn, when those needs could not be met on ranges occupied during the remainder of the year, that they moved to alternate ranges. Habitat characteristics associated with areas (grid cells) receiving relatively high and low use by radio-collared females are listed in Table 17. Variables significantly influencing intensity of use differed between summer and winter, and among residents, autumn migrants, and summer migrants. During winter, cells used intensively by yearlong residents contained more badlands habitat than those receiving only light use (P<). Cells u
