[Animals] Mass Yellowstone Hunt Kills 1,150 Bison

[Blackfire]

• An unusually harsh winter that buried Yellowstone National Park under a heavy blanket of snow and ice this year pushed a large portion of the park’s bison herd down to lower elevations and out of the park in search of milder climes and food.

  Many were stopped from migrating even farther.

  For four months, state and federal officials have sanctioned a hunt of the shaggy, humped animals that delight millions of tourists and are a centerpiece of Native American culture and history.

  Officials said they had no choice but to approve the lengthy culling of the roughly 6,000-member herd as the animals instinctually cross the park boundary onto other public land primarily to the north in Montana’s Paradise Valley, but also west of the park. It is part of a strategy to prevent them from getting near livestock, because some 60 percent of the bison herd carries a disease, brucellosis, that could infect cattle and cause cows to abort their calves.

  But in the last several weeks, the scope of the hunt, conducted mainly by members of eight Indigenous tribes, along with other park control measures, has generated more criticism than previous hunts. As the culling winds down, the record-breaking number of bison removed from Yellowstone’s herd has climbed to more than 1,530 — including hundreds of pregnant females that would have soon been giving birth. Hundreds more were sent out of the park — some to slaughterhouses and about 285 to a quarantine site where they will be held to determine if they are disease-free. The healthy ones will be sent to homes on Native American lands elsewhere.

  Yet another estimated 800 have been captured and held to protect them from the hunt.

  Government officials and conservation groups have wrestled with ways to manage the annual migration for decades.

  “It’s probably the single-most challenging wildlife issue in Yellowstone,” Cam Sholly, the park superintendent, said in an interview. “The bison is the only species we constrain to a boundary.”

• It’s a complex management scenario. Once the bison cross an invisible national park boundary and wander into Montana to the north and west on national forest land, they become the responsibility of the state.

  Under historic treaties bestowing the rights to take buffalo, members of the Nez Perce, Blackfeet, Confederated Tribes of the Umatilla Reservation, Northern Arapaho, Confederated Salish and Kootenai Tribes, the Crow and Shoshone-Bannock Tribes traveled to the region and harvested nearly 1,100 bison.

  “It’s a very cultural and spiritual endeavor and brings our families together,” said Jeremy Red Star Wolf, of the Confederated Tribes of the Umatilla Indian Reservation. “And it gives us an opportunity to talk about who we are and where we come from.”

  About 90 were shipped to slaughter facilities, and 75 were killed by other hunters.

  “We don’t want to see this many bison taken out of the po[CENSORED]tion in normal years,” Mr. Sholly said. “But we have had three years of very light migration out of the park. This is one of the first major migrations out of the park for a considerable amount of time.”

  Recent studies indicate that the po[CENSORED]tion should not be reduced to fewer than 3,500, Mr. Sholly said, to ensure genetic diversity. With a new calf crop this spring, the po[CENSORED]tion should be about 5,000, he estimated.

  Some have questioned whether killing so many animals disrupts the herds’ social structure. Mr. Sholly conceded the point, but said hunting was less invasive. “When shipping to slaughter occurred in the past, a lot of times you are taking an entire family,” he said. “The hunting is more sporadic and takes out individuals, not necessarily a whole family unit.”

• The park is home to the wildest bison po[CENSORED]tion in the contiguous United States, where there are virtually no fences, and where it is subject to myriad forces of nature, from weather to grizzlies and wolves. An adult bull bison can weigh up to 2,000 pounds, and cows weigh up to 1,000 pounds. Females and calves gather in herds, while bulls are usually solitary.

  Yellowstone officials have also been able to diminish the practice of sending bison to slaughterhouses by expanding the hunting and increasing the numbers now given to tribes to enlarge their herds or create new ones.

  Still, some critics of the hunt note that there has never been an outbreak of brucellosis infection among Montana’s roughly two million cattle that could be traced to Yellowstone bison. Bradley De Groot, the brucellosis program veterinarian for the state’s livestock department, credited constant monitoring and interventions.

  The wildlife in the greater Yellowstone ecosystem are the only known U.S. reservoir of the disease, according to the federal Animal and Plant Health Inspection Service.

  If cattle were to become infected with the highly contagious Brucella abortus bacterium, it would result in a lockdown of the animals. (The disease localizes in reproductive organs and is passed primarily through fetal tissue after birth.) “For livestock operations that are quarantined, the only place they can sell sexually intact animals is straight to slaughter,” Mr. De Groot said. “That puts a dramatic impact on their ability to continue to generate revenue.”

• Deer, moose and other species can also harbor brucellosis, but are less of a primary source of contagion.

  The hunt by Indigenous tribes is, in part, an effort to restore their ruptured relationship with the bison. At least 30 million once grazed across the West, and for thousands of years they were a vital source of food; their hides were used for shelter and clothing; and their vast roaming was a symbol of freedom. They were slaughtered in massive numbers in the late 19th century to force tribes onto reservations and for profit. Some experts say climate changes and disease brought by cattle contributed to the bison’s decline.

  The forced extinction reduced the once seemingly limitless herds to a handful, including some two dozen here at Yellowstone. Today’s herds are descended from the remnant po[CENSORED]tion.

  Beginning late last year, hundreds of Indigenous hunters from the Northwest United States have flocked to the boundaries of Yellowstone, especially to a small area called Beattie Gulch, adjacent to the park’s northern border.

  Some hunters have traveled with their families to harvest buffalo. Kola Shippentower-Thompson, a member of the Confederated Tribes of the Umatilla Indian Reservation in eastern Oregon, hunted with her husband, Tommy Thompson, who is the Umatilla tribal game warden, and her cousin, Dion Denny.

  Ms. Shippentower-Thompson said she had shot 13 bison since December, including a big bull last month, her first. After it fell to the snow, she and her husband gutted it, and she took a ceremonial bite of the old bull’s heart
