Wood bison: giant blast from the past
Biologists hope to re-establish herds of the 2,000-plus-pound beasts

Pelted with fat drops of rain in a grassy field not far from Portage Glacier, a chocolate-brown wood bison shook its coat like a wet dog, flinging water in all directions.
It was a scene straight out of Alaska's distant past. And, biologists hope, its near future.
Bison lived in Alaska for more than 400,000 years but then disappeared in a drought spurred by changing habitat and hunting, biologists say. Wood bison -- a tall, rangy subspecies well suited to the cold -- haven't been seen here for roughly 100 years or more, according to Fish and Game.
Now they're back.
In June, the state packed more than 50 wood bison into a pair of special semi trailers and trucked them from Canada to the Alaska Wildlife Conservation Center in hopes of creating a new seed stock that could one day repopulate portions of the state.
The bison imported last month aren't alone. They join another 30 or so bison that a Delta Junction rancher illegally brought into Alaska within the past 10 years, according to the state.
Those animals were at the Conservation Center too. They're the ones visitors were most likely to spot Tuesday, chewing absently and lounging in the wet grass with their rusty brown calves. The newer bison are smaller, more shy and less used to human gawkers.
Tuesday, biologists trumpeted the arrival of the new animals and pitched their plans for re-establishing herds across the state.
"All the wood bison in the United States of America are here," Fish and Game spokeswoman Cathie Harms said Tuesday. (No, she's not counting zoos.)
"They're very rare in the United States right now, and we've got them," she said.
Alaska already has about 800 to 1,000 so-called "plains bison" in the wild, said Fish and Game wildlife planner Randy Rogers.
Unlike wood bison, plains bison aren't native to the state and were first brought to the Delta area from Montana in 1928.

Wood bison are bigger -- a bull can hit 2,200 pounds or more -- darker, and with a squarer hump.
"Wood bison are the largest land mammal in North America," Rogers said.
Biologists once thought the subspecies hadn't lived in Alaska for hundreds if not thousands of years. But Athabascan elders talk of relatives who remember the big animals, said wood bison project biologist Bob Stephenson.
In 1969, an archeologist and his kids found a wood bison skull in Anchorage's Chester Creek. Radiocarbon-dating said it was about 170 years old.
Stephenson has been talking about bringing the animals back to their former range in the Interior for more than 15 years.
Bringing the bison back would be good for soil, good for bison and good for Alaska's ecology, he said.
They're also good eating, Stephenson said, comparing the meat to grass-fed beef.
Researchers see the bison playing another role -- preparing Alaska for global warming, or climate change.
Some University of Alaska Fairbanks professors predict our boreal forests may start converting to grasslands, Rogers said, which are better suited to a grazing animal like bison than to moose that browse woody stems and shrubs.
The state hopes to put the bison in three areas -- the Minto Flats, the Yukon Flats, and Innoko/Yukon River area.
The project could cost $500,000, Stephenson said. Television mogul Ted Turner kicked in $100,000 through his endangered species fund.
Arnold Hamilton, from the village of Shageluk, sat on an advisory board on the bison project. He hopes bringing wood bison to his region will ease hunter competition for moose.
But how's the meat taste? Hamilton was diplomatic. "It's different," he said.
The state plans to hold the Canadian wood bison in quarantine for about two years before taking some of the animals to the Minto Flats area to kick off the restoration project.
"It's a smaller area but it has road access. We think we could have 400 or 500 there," Rogers said.
In the meantime, there's still plenty of work to do.
For example, Doyon Ltd. -- a Fairbanks-based Native corporation -- considers the Minto and Yukon flats as potential places to explore for oil and gas. Things get complicated if the bison are placed in those areas and considered an endangered species.
"While we support the general notion of reintroduction of wood bison in both places, we don't support reintroduction currently when there are Endangered Species Act implications," said Jim Mery, Doyon vice president of lands and natural resources.
Rogers said the state is looking into getting a special ruling from the U.S. Fish and Wildlife Service that would allow for moving the bison without impeding development.
After the state moves the bison to their new home, it would likely be another 10 years before hunting is allowed, according to Fish and Game.
