All but one of Yellowstone\u2019s nine packs lost wolves to hunters and trappers. The Junction Butte Pack was hit the hardest. Eight wolves from the once 35-animal-strong mega pack were shot or trapped over the boundary.<\/p>\n\t\t<\/div>\n\t\t\t<\/blockquote>\n\n

MIKE KOSHMRL:<\/strong> A recent spate of wolf killings just outside of Yellowstone National Park has altered fundamental aspects of the canines\u2019 behavior, and threatened the foundations of one of the most storied wildlife research efforts in American history, according to park scientists.<\/em><\/p>\n

Twice in recent months Yellowstone National Park senior wildlife biologist Doug Smith and his team of researchers have observed highly unusual mating behavior. Many more wolves have been getting frisky than expected. Ordinarily in Yellowstone, only each pack\u2019s dominant alpha male and female get the opportunity to mate. The custom is reflected in 27 years of hard data: 85% of the time, park packs produce single litters.<\/em><\/p>\n

But this year \u2014 in the wake of at least 25 wolves being shot or trapped just beyond the park\u2019s boundaries \u2014 Yellowstone Wolf Project personnel observed three or four females in two different Northern Range packs \u201ctied\u201d and breeding, Smith said. \u201cUsually the most dominant wolf prevents other wolves from breeding,\u201d he said. \u201cYou lose that [dominant] wolf and it opens up opportunities for other wolves.\u201d<\/em><\/p>\n

It appears, in other words, that with their pack hierarchies disrupted by the record-setting killings, some wolves have abandoned their selective mating customs. \u201cWe have multiple females pregnant in at least two packs \u2014 Junction and Wapiti \u2014 that could be due to the mortality that we\u2019ve experienced,\u201d Smith said. \u201cIt\u2019s broken apart the social structure, it\u2019s messed with the hierarchy, and it\u2019s actually produced more pups. Now this is a hypothesis, but this is what I would call an artificial stimulation of wolf reproductive capacity. By going in and killing them, you stimulate reproduction.\u201d<\/em><\/p>\n

Yellowstone\u2019s Northern Range is widely regarded as the best place on the planet to watch wild wolves. For researchers it holds a unique appeal: In the Lower 48, Yellowstone is the easiest place to observe wolves in their natural state.<\/em><\/p>\n

Since the U.S. Fish and Wildlife Service reintroduced 31 wolves to the park in 1995 and \u201996, the intensive research effort has been predicated on understanding wolf ecology in the absence of human persecution. Yellowstone\u2019s 2.2 million acres have proven a grand arena for this research. Outside of Yellowstone about 80% of Idaho, Montana and Wyoming wolf deaths can be attributed to people, Smith said, but just 2% to 3% of wolves within the park\u2019s boundaries succumb to humankind.<\/em><\/p>\n

\u201cHuman-caused mortality is the story of wolves across North America,\u201d Smith said. \u201cOne place that was not the case was Yellowstone, and we\u2019re not anymore.\u201d Smith estimates it will take three to five years for Yellowstone\u2019s wolf population to revert to a more natural condition following the 2021-22 state managed hunt \u2014 provided Montana changes the rules that allow wolf hunters to aggressively pursue the naive, human-conditioned canines without limit just outside the protected park.<\/em><\/p>\n

All but one of Yellowstone\u2019s nine packs lost wolves to hunters and trappers, he said. The Junction Butte Pack \u2014 Yellowstone\u2019s most visible wolf pack thanks to a den site near the road \u2014 was hit the hardest. Eight wolves from the once 35-animal-strong mega pack were shot or trapped over the boundary.<\/em><\/p>\n

The Phantom Lake Pack, typically positioned between Junction Butte\u2019s territory and the northern park boundary, used to keep the Junction Butte wolves from straying out of Yellowstone. But after six of its wolves were killed by boundary hunters, the remaining Phantom Lake wolves dispersed.<\/em><\/p>\n

\u201cThey\u2019re gone,\u201d Smith said. Other packs lost particularly influential wolves. An \u201cunmistakable\u201d half gray, half black 8-year-old alpha female from the 8 Mile Pack, for example, was caught in a trapper\u2019s set outside the park boundary, Smith said. \u201cAfter she was dead,\u201d he said, \u201cthe rest of the pack went places that they haven\u2019t been in 10 years”. <\/em>SOURCE…<\/em><\/strong><\/a><\/p>\n
