Study Examines What Scares Elk More – Human Hunters or Wolves?

ISLAND PARK, Idaho - Elk behavior is definitely changing in the Greater Yellowstone area, according to a report published in the "Journal of Wildlife Management." Researchers using GPS technology have been following elk, wolves and hunters there to find out how elk respond to threats from predators and sportsmen.

The results were not what the scientists expected, explains one of the researchers, terrestrial biologist Jamin Grigg of the Colorado Division of Wildlife.

"Both wolves and human hunters had impacts on elk movement and elk distribution, but we found that hunters generally had larger impacts."

Elk congregated in smaller groups and traveled farther when hunters were present than when wolves were active, Grigg says, which indicates elk sensed more of a threat from humans than from wolves. The bottom line, he says, is that elk are more sensitive to human activity than wolf activity. That is important to note in all kinds of wildlife and public lands decisions, he adds.

"Management agencies can use that information to structure hunting seasons, to allocate hunting licenses, to evaluate travel management plans up on the forest."

Regardless of whether human hunters or wolves are affecting elk migration, if the result is that elk spend more time grazing on private pasture instead of on public lands, that's a concern for livestock producers who own those rangelands, Grigg suggests.
