DATA SHOW NO STRONG LINKS BETWEEN WOLF NUMBERS
AND IDAHO ELK DECLINES
Research Shows Elk Declines Not Significantly Greater Where Wolves Present
PRAY, Montana – Wolves "cannot plausibly account for the majority of elk ‘missing’ from the Idaho elk harvests since 1995," according to new research presented today by wildlife biologists associated with Defenders of Wildlife and Nez Perce wildlife management. They found that elk harvest declines were not significantly greater in areas with wolves than in those without, and that wolves cannot be linked to declines in elk density.
"The numbers couldn’t be clearer. Wolves can’t plausibly account for a majority – never mind all – of reduction in the elk taken by hunters in Idaho," said Dr. J. Christopher Haney of Defenders of Wildlife. "It’s particularly telling that elk harvests have declined by about the same amount in areas without wolves as in those with them."
Haney and Dr. Keith Lawrence presented their preliminary findings today at the 17th Annual North American Wolf Conference in Pray, Montana. They addressed head-on the explosive question of whether reintroduced wolves were responsible for declines in hunter harvests of elk.
They looked at the question from two different perspectives. First, they excluded inverse associations between wolves and elk in Idaho – did elk numbers decline by more in areas with wolves than in those places without them? Second, they analyzed well-established rates of wolf predation on elk, to determine if the number of wolves in the region could possibly account for the numbers of elk "missing" from elk hunt numbers since 1995.
On both counts, the data clearly show that factors other than wolf predation play a much larger role in elk availability to hunters than the presence or absence of wolves. In fact, since wolf reintroduction in Idaho, hunter effort was the best predictor of elk harvest levels, not wolf numbers.
