BILLINGS, Mont. (AP) — Federal officials said Monday that 20 parcels of public lands in 10 states could be suitable for bison from Yellowstone National Park, although it's likely to be years before any animals are relocated to the sites.
The locations 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, and had roughly 4,600 bison at last count. During their winter migrations, the animals periodically spill into neighboring Montana, triggering large-scale bison slaughters to prevent the spread of the animal disease brucellosis.
A pilot bison relocation program in Montana has struggled to overcome opposition from ranchers. They worry both about the disease and the possibility of bison competing with cattle for grazing space.
The pilot program quarantined Yellowstone bison for several years before they could be moved, to protect against disease transmissions. Even so, many within the livestock industry remain wary and most of the animals in the program have not yet been relocated.
Those animals are in control of Montana Fish, Wildlife and Parks, which is considering proposals from tribes, government agencies and private groups that want to take the bison.
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, an official with the U.S. Department of the Interior.
