Ten states considered for relocating park bisonJul 1, 2014 The Associated Press
BILLINGS, Mont. -- Federal wildlife officials on Monday listed 20 parcels of public lands in 10 states that could be suitable for bison from Yellowstone National Park, but said it would be years before any relocations of the animals.
The sites eyed for potential future herds include areas as diverse as Arizona's Grand Canyon National Park, an Iowa wildlife refuge, and a North Dakota national historic site.
They were identified in a long-awaited Department of Interior report that looked at using Yellowstone's bison herds to further the restoration of a species that once ranged most of the continent.
Tens of millions of bison occupied North America before overhunting nearly drove them extinct by the late 19th century.
Yellowstone was one of the last holdouts for the animals in the wild. It had roughly 4,600 bison at last count, more than many wildlife managers recommend. During their winter migrations, the animals periodically spill into neighboring Montana, triggering large-scale, government-sponsored bison slaughters to prevent the spread of the animal disease brucellosis.
Capturing the animals and shipping them to other public lands would ease those population pressures.
A pilot bison relocation program in Montana has struggled for years against opposition from ranchers. They worry both about the disease and the possibility of bison competing with cattle for grazing space.
Several dozen Yellowstone bison have been moved onto American Indian reservations in the state after the animals were held in quarantine for years to make sure they were disease-free.
Efforts to relocate another group of about 145 bison that went through the quarantine have stalled. Montana Fish, Wildlife and Parks officials in June said they were considering new requests to take the animals from tribes, private conservation groups and the state of Utah.
If the park service were to revive the quarantine program and make it permanent, federal officials said it could be five years to a decade before more animals were relocated.
"If we were to do this, where would you place these bison? This report gives us a head-start on that question," said Jorge Silva-Banuelos, a U.S. Interior Department official.
Some of the 20 sites listed Monday already have bison.
