Collecting fallen antlers and horns from some of Colorado’s mammals is a beloved pastime for many. While picking up antlers that get left behind may seem like a pretty straightforward process, there are actually a few rules and regulations to be aware of – and it could cost you big time if these rules aren’t followed.

Shed antler and horn collection is prohibited on all public lands west of I-25 from January 1 through April 30 in Colorado.

Additionally, the Gunnison Basin is closed from May 1-15 from sunset to 10 a.m. to further protect the Gunnison sage-grouse. This closure applies to public lands in Game Management Units 54, 55, 66, 67, and 551.

According to Colorado Parks and Wildlife, these regulations are in place to reduce stress on wintering big game animals (including deer, elk, pronghorn, and moose) during a time of year when they are most vulnerable. Stress can result in “decreased body condition, increased mortality, and decreased fawn/calf survival.”

Winter can be a stressful and difficult time for wildlife, as body weight drops and access to food is limited. CPW explains that winter conditions affect big game into late April or early May, and the April 30 date is chosen to “minimize additional stress during this critical time frame.”

Violators of these regulations may face a $137 fine per violation and five hunting license suspension points. Shed antler hunting and the illegal possession of each shed antler are separate offenses. If someone accumulates 20 or more license suspension points within five years they could be suspended from hunting and fishing for up to five years.

While there are some pretty strict penalties for illegal hunting, following the rules and regulations as laid out by Colorado Parks and Wildlife more important helps Colorado’s wildlife survive and thrive.
