According to state and federal scientists, the population of a major elk herd that migrates between Yellowstone National Park and Montana is down by 10 percent in 2012 (in 2011 the herd saw a 24% drop). The 2012 numbers are roughly, 4,174 elk in the herd. Experts attribute the drop in population to the cumulative effects of predator attacks, a difficult winter, and hunters.

The herd’s population peaked in 1992, when an estimated 20,000 elk roamed the park. That was just a few years before park officials reintroduced wolves to the area. Since the wolves’ return—they had been absent for decades—elk population levels have returned to historic averages.

However, Yellowstone biologist Doug Smith says that the wolves cannot be blamed entirely for the decline of the elk herd. The wolves' populations have been decreasing as well, from 94 in 2007 down to 38 in 2011. Smith blames the elements: "This was one of the hardest winters we've had in decades,” he told the Associated Press (via “We've got a leaner, meaner elk herd."

Montana Wildlife officials will instate a new permit system as a way to dissuade hunters from killing members of the Northern Yellowstone herd. There will be unlimited numbers of the $9 permits, but experts expect the new requirement to be a deterrent.



Yellowstone Bison Hunt Takes Record Numbers

So far in 2013 hunters have killed more wild bison migrating from Yellowstone National Park than any year since 1989. Participation by American Indians, who harvest the animals under long-standing treaty rights, helped to drive the numbers skyward.
