The annual elk reduction program in Grand Teton National Park begins on October 6.
Federal law requires the park to maintain a sustainable population of the Jackson elk herd. To keep the numbers low enough, they’ve had to harvest elk each year for decades.
Park Spokeswoman Jackie Skaggs says an over-sized elk herd could harm the park.
“The risk of having too large of a population is that they would over-graze the range," Skaggs said. "And that would probably be a detrimental impact to other species.”
