These herbivorous, game animals are found at all elevations, but will exhibit seasonal altitudinal migrations. They occupy winter range from December to April. Sun-exposed, south facing slopes are critical for winter food availability. The rut occurs during November and December. After a 6-7 month gestation period, the precocial young are born from May to July. Weaning begins at 5 weeks of age. Mule deer winter habitat has been severely impacted by fires in our area. Deer hunting is allowed with proper permits within the Reserve. If illegal poaching of mule deer or any other protected wildlife is observed, please report to the poaching hotline: 1-800-662-3337.
In the Red Cliffs Desert Reserve, mule deer are most commonly observed during late fall and winter, especially along the Cottonwood Springs Road. In higher country, they may be observed year-round.
