Spanning five American states, two Canadian provinces, two Canadian territories, and at least 75 Indigenous territories, the Yellowstone to Yukon region is unlike any other in the world. This incredible landscape of over half a million square miles — or 1.3M square kilometers — represents the most intact large mountain region in North America.
We know that keeping this vital region intact is the best way to tackle the loss of biodiversity and a changing climate. Y2Y’s work addresses the needs of the region’s wildlife and people, giving animals freedom to roam and protecting habitat for grizzly bears, caribou, wolves, and more.
We identify core habitat across this important landscape and work with partners to protect it.
We collaborate with communities to create safe wildlife corridors and mitigate barriers that wildlife face as they move throughout the region.
