Colorado Parks and Wildlife managers say they’re compelled to allow hunting to control mountain lion numbers amid a human population growth and development boom drawing more people onto lion habitat. They point to “conflicts,” saying staffers received 116 calls about lions over 13 months from people in the Roaring Fork and Eagle River valleys. In one case, a lion was brushing up against stopped vehicles before it and another lion were found dead a few days later along Highway 82. Lions also have raised alarms by wandering near a school and homes, where they occasionally snatch pets.

Colorado officials are basing their plan on a statewide estimate of 4,000 to 5,500 lions today, half a century after bounty killing pushed this species toward extinction.

The CPW 10-year plan, up for approval this summer by state wildlife commissioners, calls for preserving mountain lions while also giving opportunities to hunters, who currently are allowed to kill lions at levels intended to reduce numbers across 11,372 square miles in western Colorado designated for “suppression.”
