Bison, the iconic animal of the American west, could once more roam wild across the great plains under a recovery roadmap prepared by international scientists.
A report by the International Union for the Conservation of Nature (IUCN) (pdf), prepared by dozens of scientists and bison experts from Mexico, America, and Canada, says there is a chance of a second recovery, nearly a century after the animals were rescued from the brink of extinction.
But success depends on allowing large herds to roam free over thousands or perhaps millions of hectares, an overhaul of government regulations, and a rethink of public attitudes to the animal.
