2008 Mar 23. Anger Over Culling of Yellowstone's Bison By JIM ROBBINS, NY Times. Excerpt: GARDINER, Mont. - This was not the Yellowstone National Park that tourists see. ...more than 60 of the park's wild bison were being loaded on a semi-trailer to be shipped to a slaughterhouse. With heavy snow still covering the park's vast grasslands, hundreds of bison have been leaving Yellowstone in search of food at lower elevations. A record number of the migrating animals - 1,195, or about a quarter of the park's population - have been killed by hunters or rounded up and sent to slaughterhouses by park employees. The bison are being killed because they have ventured outside the park into Montana and some might carry a disease called brucellosis, which can be passed along to cattle.
The large-scale culling, which is expected to continue through April, has outraged groups working to preserve the park's bison herds.... ...The standoff has been made all the worse by the detection last year of brucellosis in several cattle elsewhere in Montana. Though experts believe the disease was transmitted by elk, not bison, the case has stirred passions among ranchers. Brucellosis ...when detected, requires that the cattle be destroyed. If another incidence of brucellosis appears in Montana, the state would lose its brucellosis-free status, ....
"Our interest is having a brucellosis-free United States," said Mr. Knight, the agriculture official. "The sole remaining reservoir is in the Greater Yellowstone. ...the best solution would be a vaccine for bison, .... Park officials, however, say it is not known when a vaccine, which they are researching, will be available.... In the last few years biologists have discovered that Yellowstone's bison are one of only two genetically pure herds owned by the federal government.
James Derr, a professor of genetics at Texas A&M who is studying the Yellowstone bison, said he feared that some behaviors or traits, including the propensity to migrate, could be lost with the killed bison. "The great-grandmother, grandmother, mother and daughter often travel together," he said. Killing them "is like going to a family reunion and killing off all of the Smiths. You are affecting the genetic architecture of the herd."...

13 February 2007. Sharing of Bison Range Management Breaks Down. By JIM ROBBINS, New York Times. Excerpt: MOIESE, Mont. - An effort to have two Indian tribes assist government officials in operating a federal wildlife refuge that is surrounded by their reservation has collapsed amid accusations of racism, harassment, intimidation and poor performance. But top federal officials say they are determined to resurrect it. ...The Indian Self-Determination Act of 1975 allows tribal involvement in the management of federal lands, and the Confederated Salish and Kootenai Tribes, which have strong cultural links to bison, wanted the authority to manage the refuge. The Fish and Wildlife Service opposed ceding control over the bison range, and the Interior Department and tribal officials decided to split the mission. ..
