Abstract: Mule deer (Odocoileus hemionus), white-
tailed deer (Odocolieus virginianus), and pronghorn
antelope (Antilocapra americana) use of 6 agricultural
land use categories in southeastern Montana were
monitored to identify use patterns at specific sites.
Alfalfa (Medicago sativa L.), bottom rangeland,
Conservation Reserve Program (CRP) lands, upland
rangeland, wheat (Triticum aestivum L.) stubble, and
growing wheat were observed during dawn, day,
dusk, and night hours over a period of 12 months.
Mule deer densities on alfalfa peaked in fall and
again in spring. The CRP lands were selected in all
seasons. Rangeland sites were most heavily used in
winter and summer. White-tailed deer used CRP
lands in all seasons except fall. Alfalfa was selected
in fall, spring, and summer. Antelope densities on
alfalfa were highest in spring and fall, while growing
wheat fields were used most in spring. Antelope in
the northern study area selected CRP land in all
seasons except fall. Densities of animals and
patterns of use observed during this study would be
unlikely to produce significant impacts on forage or
crops at most of our study sites.
