Study: Reintroducing just 20 species in strategic locations could boost global biodiversity a lot

For thousands of years, bison herds thundered freely throughout the Chihuahuan Desert on both sides of what is now the U.S.-Mexico border. In November 2009, after three frantic months of chasing down the required permits, Rurik List and Nélida Barajas watched as 23 bison from Wind Cave National Park in South Dakota arrived by tractor-trailer at the Santa Teresa international cattle crossing in southeastern New Mexico.


The animals, 20 females and three males, galloped through the dusty stockyards, across the border, and into the state of Chihuahua. A permanent herd of wild bison had been missing from Mexico for more than 150 years. “It’s hard to describe the feeling,” says Barajas. “We were bringing the bison back home.”
