Colorado To Kill Bears, Mountain Lions In Bid To Boost Mule Deer

DENVER Colorado officials will proceed with a controversial plan to kill dozens of mountain lions and bears to bolster the state’s declining mule deer population. 

Wednesday’s vote by Parks and Wildlife commissioners authorizes specialized contractors to kill up to 25 black bears and 15 mountain lions per year across two regions in the central and western parts of the state. The project will run for three years, to be followed by a six-year study of how deer populations respond to fewer predators. 

The population of Colorado’s mule deer, a prized quarry of hunters, has dropped sharply in a puzzling, decades-long decline to about 450,000 animals, which state officials said was about 110,000 fewer than there should be. 

A 2014 state study tied the decline to seven factors, including predators, whose numbers have swelled because of a “decline in frequency of severe winters.”

Critics, however, said the state should focus first on the human-led destruction of mule deer habitat.

Amule deer (Odocoileus hemionus) is a deer indigenous to western North America; it is named for its ears, which are large like those of the mule.

“The decline of mule deer in western Colorado and around the west is obviously a complex issue with complex causes,” Brian Kurzel, Rocky Mountain regional director for the National Wildlife Federation, told The Huffington Post. “By far, the greatest issue — and one that I think deserves the most attention in any science-based study — is habitat quantity and quality.”

Kurzel pointed out that the U.S. Bureau of Land Management recently approved 15,000 new oil and gas wells in a patch of western Colorado sometimes referred to as “the mule-deer factory,” where the herd has declined to about 30,000 from more than 100,000 in the early 1980s. Though state officials have acknowledged oil and gas development affects mule deer populations, they didn’t oppose the federal decision.

Other factors, including highways (which disrupt migratory corridors), residential growth and human recreation are also curbing the mule deer population, Kurzel said.

State Parks and Wildlife officials don’t necessarily disagree. They pitched the $4.5 million predator-culling program as a way to gather research for later decisions.

“We acknowledge that any and all those things can have an effect on mule deer,” Jeff Ver Steeg, the Parks and Wildlife assistant director for research, policy and planning, said at Wednesday’s meeting. “We’re in the business of learning … We have come up with a new hypothesis … We are proposing to act in the form of research.”

The state budget and the contribution of deer hunters to it also may be a factor. The Denver Post reported Parks and Wildlife gets 90 percent of its funding from hunting and fishing licenses.

The department denied that its plan to kill predators of animals prized by hunters is influenced by money, but there’s no question more diversified funding would be a good thing, especially if deer populations continue to decline.
