A NEW HOME ON THE RANGE?
"Pleistocene Park" may not have the same cinematic cachet as its Jurassic cousin, but a controversial proposal to introduce free-ranging lions, cheetahs, elephants and other wild animals to North America's Great Plains is generating its own share of dramatic reviews.
The "rewilding" of parts of North America's heartland could restore some balance to an ecosystem that lost a slew of similar species around 13,000 years ago, according to a commentary in this week's issue of the journal Nature. Although conceding that "huge cultural obstacles" would have to be surmounted, lead author and Cornell University ecologist Josh Donlan argues that the long-range plan also might help preserve animals in danger of extinction elsewhere."
