The next 10 to 20 years could be extremely significant for restoring
wild populations of American bison to their original roaming grounds.
But for this to happen, more land must be made available for herds to
roam free, government policies must be updated and the public must
change its attitude towards bison, a new report says.
A new publication by the International Union for Conservation of
Nature (IUCN), American Bison: Status Survey and Conservation
Guidelines 2010, reports on the current status of American bison,
in the wild and in conservation herds, and makes recommendations on how
to ensure that the species is conserved for the future.
"Although the effort to restore bison to the plains of North America
is considered to be one of the most ambitious and complex undertakings
in species conservation efforts in North America, it will only succeed
if legislation is introduced at a local and national level, with
significant funding and a shift in attitude towards the animal," says Dr
Simon Stuart, Chair of IUCN's Species Survival Commission.
Five hundred years ago, tens of millions of American bison roamed
free on the plains of North America, from Alaska to northern Mexico. Now
the American bison -- which includes both plains and wood bison -- is
listed as Near Threatened on IUCN's Red List of Threatened Species™. As
of 2008, there were approximately 400,000 bison in commercial herds in
North America, some 93 percent of the continental population. But little
progress has been made in recent decades to increase the number of
animals in conservation herds, which are managed carefully for their
genetic diversity and ecological roles. In 2008, there were 61 plains
bison conservation herds in North America containing about 20,500
animals, and 11 conservation herds of wood bison, containing nearly
"While substantial progress in saving bison from extinction was made
in the 20th century, much work remains to restore conservation herds
throughout their vast geographical range," says University of Calgary
Environmental Design Professor and co-editor of the study, Dr Cormack
Gates, who is also co-Chair of the IUCN Bison Specialist Group. "The
key is recognition that the bison is a wildlife species and to be
conserved as wildlife, it needs land and supportive government
The survival of bison populations is affected by many factors,
including limited habitat and severe winters. Yet the greatest challenge
is to overcome the common perception that the bison, which has had a
profound influence on the human history of North America, socially,
culturally and ecologically, no longer belongs on the landscape.
"The decimation of the American bison in the late 1800s
inspired the first recovery of bison and an entire conservation movement
that protected wildlife and wild places across North America," says
Keith Aune, Senior Conservation Scientist, Wildlife Conservation
Society. "The IUCN Status Survey and Conservation
Guidelines provide a new framework for inspiring a second recovery
of bison and restoring functional grassland ecosystems."
Bison have the best chance of full recovery as wildlife by being
allowed to roam freely across hundreds of thousands or even millions of
hectares. Making this possible poses one of the biggest challenges for
restoring bison herds as both public and private landowners will need to
give their support.
"The bison is the largest land mammal in North America, and yet it is
perhaps the most neglected icon," says Steve Forrest, WWF Northern
Great Plains Manager for Conservation Science. "These guidelines provide
a roadmap for bringing the bison back to its rightful place as a
keystone of the great plains."
American Bison: Status Survey and Conservation Guidelines 2010was edited by Cormack Gates, Curtis Freese, Peter Gogan
and Mandy Kotzman, and is the product of more than three years of
cooperative effort by numerous contributors. Production of the report
was made possible with funding from several non-governmental
organizations and government agencies including the World Wildlife Fund,
the Wildlife Conservation Society, the University of Calgary Faculty of
Environmental Design, the American Bison Society, the US Geological
Survey and the US National Parks Service.
