Native species such as swift foxes and black-footed ferrets disappeared from the Fort Belknap reservation in the United States generations ago, wiped out by poisoning campaigns, disease and farm ploughs that turned the open prairie into cropland and cattle pastures.
Now, with guidance from Native American elders and outside wildlife groups, students and interns from the tribal college are helping to reintroduce the small predators to the northern Montana reservation, which sprawls across more than 2,600sq km (1,000 square miles) near the US-Canada border.
