The situation
What’s happening to Greater Yellowstone Ecosystem
The last intact temperate ecosystem in North America, and the park boundary means nothing to the grizzlies, wolves, and bison that cross it daily. Beyond the line, mining proposals, grazing conflicts, and wildlife management rollbacks are dismantling the ecosystem that makes Yellowstone possible. One lease sale, one hazing operation, one bullet at a time.
