Disease may be exacerbated by warm water, low stream flows
The Yellowstone River, part of Montana’s iconic western landscape, is once again beset by environmental woes, as a rapidly spreading fish kill has spurred state resource managers to close the river to all recreational uses, including fishing, boating and tubing. Biologists with Montana Fish, Wildlife and Parks said they’ve counted more than 2,000 dead mountain whitefish, and the estimate the total mortality in the tens of thousands. The river was also hammered by an oilspill in 2011 after pipeline burst. Continue reading “Environment: Massive fish kill reported in Yellowstone River”→
Elk deemed mostly responsible for spreading disease to livestock
The most rapidly spreading strains of brucellosis, a disease with implications for livestock and wildlife management, appear to be centered around areas where humans feed elk to keep populations artificially high for hunters.
Those findings come from scientists with the U.S. Geological Survey and partners, who studied how the disease is transmitted back and forth between cattle, bison and elk in the greater Yellowstone area. Notably, the researchers found that a fifth, genetically distinct strain, originated, and was mainly found in bison of Yellowstone National Park. This strain appeared to be spreading less rapidly.

FRISCO — Wildlife managers in Montana are exploring options for restoring bison to parts of the state where they haven’t roamed in more than 100 years.
Bison were nearly eliminated from their historic range more than a century ago. By the late 1890s, only 1,000 bison remained in North America, and most of these animals were held on private ranches where they were interbred with cattle. By 1902, only 25 bison remained in the wild in the U.S., seeking refuge deep within Yellowstone National Park. Today, this Yellowstone herd numbers around 4,500 animals.

FRISCO — Despite polls showing widespread public support for relocating Yellowstone bison to start herds in appropriate locations across the state, the National Park Service has once again started rounding up wild bison for slaughter.
The animals wander out of the park each winter searching for food at lower elevations. This year’s killing program is slated to be the largest in seven years to cap the bison population in the park at 3,500, part of a settlement with the state of Montana over now-discredited concerns about brucellosis and carrying capacity.
FRISCO — A Montana district court judge this month rejected yet another attempt by ranchers to block the restoration of bison in the northern plains. The ranchers sought to have wild bison classified as livestock rather than wildlife, but Montana District Judge John McKeon ruled last week that wild bison are wildlife under state law — regardless of their confinement in quarantine.
A legal classification as livestock would have transferred jurisdiction over quarantined bison from the Montana Department of Fish, Wildlife and Parks to the Montana Department of Livestock—a move that threatened to impede any future efforts to restore native bison as a wildlife species in appropriate portions of their historic habitat.
