Gunnison Basin 2017 Winter Big Game Baiting Operation

​The weather for the week of Feb. 20 is predicted to be mild with highs in the 40s. Some snow is expected this week, but warm temperatures are helping to melt snow and reveal vegetation. 

CPW has stopped baiting deer west of Gunnison. Some baiting is continuing east of Gunnison, Those sites are being evaluated to determine if it will be necessary to continue. Because of continued conflicts with ranchers, elk are still being baited at the Gunnison State Wildlife Area.   

CPW staff is monitoring winter-range conditions, making visual and physical assessments of the body-condition of deer, surveying locations of deer herds, looking for evidence of road kills and monitoring weather conditions. 

Winter is tough on wildlife in the Gunnison Basin, but deer and elk have evolved in these conditions over thousands of years. While this year seems particularly difficult, the animals are able to find natural sources of food.  Everyone is reminded to stay well away from herds to minimize disturbance.

Tracking Winter Deer Survival

After the difficult winter of 2008, CPW started monitoring deer in the basin to determine survival. Radio collars are placed on a representative sample of deer and then tracked via telemetry. Over the past eight years, the average winter survival rate of adult does is 89 percent annually, while average winter fawn survival rate is 64 percent. 

As of Feb. 15, of the radio-collared deer which CPW is tracking, 93 percent of the does have survived, and 56 percent of the fawns have survived. Annual winter monitoring for survival continues through June 15. ​

​​​CPW biologists have been studying deer survival in the Southwest Region and throughout the state. To gain a better understanding of mule deer study and survival, please read this report: Southwest Mule ​Deer Survival.

CPW's Big Game Aerial Inventories

To manage big game herds in Colorado for long-term sustainability, CPW biologists conduct aerial surveys throughout the state every winter. Learn how surveys are conducted and what big-game biologists learn from them​. ​

Minimizing Disturbance of Big Game -- Emergency Regulation 

Deer and elk minimize their movements during the winter to save energy. If they are forced to move during the cold winter months, it reduces the chances that they will make it through the winter. In order to minimize disturbance of deer and elk now on winter range in the Gunnison Basin, CPW has enacted an emergency regulation that prohibits several forms of wildlife-related recreation on public lands at 9,500-feet and below in an area from, roughly from Sargents to five-miles west of Blue Mesa Dam, and Crested Butte to Lake City. The regulation prohibits lion hunting, small game hunting, the collection of antlers and skulls of wildlife, and suspends all night-hunting permits through May 15. See map​ and official regulation order

CPW also asks that people refrain from other forms of recreation in areas where deer and elk can be seen. This includes snowshoeing, snowmobiling, mountain biking, cross-country skiing and sledding.  Recreationists can find plenty of areas for fun activities on public lands above 9,500 feet.

Winter and Big Game

The Western Association of Fish and Wildlife Agencies brings together wildlife experts from throughout the western states. The association’s Mule Deer Working Group has assembled experts to look at and make recommendations on management of this species. Following are links to three fact sheets that explain big game issues, specifically how these animals get through the winter and how the actions of humans affect mule deer. Please, take time to read these authoritative reports.

Elk gather in herds during the winter and their numbers tap down snow to reveal vegetation. Deer have been mingling with elk to take advantage of available forage.  ​
