CSU Professor Studies Impact of Prairie Dogs

Several communities in the state are debating how to control prairie dogs, everything from fences to poison. Earlier this year, the Colorado Division of Wildlife approved use of a device called the Rodenator, which pumps a mix of propane and oxygen to blow up prairie dog burrows. Meanwhile, environmentalists think the prairie dog should be protected, not eliminated. Ryan Warner talks to CSU biology professor Jim Detling, who recently completed a study of prairie dogs in grazing areas.
