Nate Schweber, New York Times: “More than 70 percent of tribal land in the Northern Plains is unplowed, compared with around 60 percent of private land, the World Wildlife Fund said. Around 90 million acres of unplowed grasses remain on the Northern Plains. Tribes on 14 reservations here saved about 10 percent of that 90 million — an area bigger than New Jersey and Massachusetts combined…Wildlife stewardship on the Northern Plains’ prairies, bluffs and badlands is spread fairly evenly among private, public and tribal lands, conservationists say. But for a few of the rarest native animals, tribal land has been more welcoming. The swift fox, for example, was once considered for listing as an endangered species after it was killed in droves by agricultural poison and coyotes that proliferated after the elimination of wolves. Now it has been reintroduced in six habitats, four on tribal lands.”
