Photographing Animal Migrations, the Heartbeat of Yellowstone | Nat Geo Live

The successful comeback of wolves and bears in the Greater Yellowstone Ecosystem have been in large part thanks to the migration of pronghorn and elk that roam the vast landscapes. Not only are these migrations critical for sustaining the ecosystem, but they also help to sustain the local economy. National Geographic photographer Joe Riis and wildlife ecologist Arthur Middleton talk about their efforts to better understand these migrations through photography and mapping and why the vast distances these animals cover is so critical to the health of the region.
