Incredible variety from Yellowstone to Yukon  

The Yellowstone to Yukon region remains one of the few remaining intact mountain ecosystems on Earth, running 2,000 miles (3,200 kilometers) from Yellowstone to Yukon. Y2Y’s goal is to keep it this way.

At 502,000 square miles (1.3 million square km) it is equivalent in size to twice that of Texas or Alberta. 

This dynamic landscape is home to: 

  • The full suite of wildlife that were present when Europeans first arrived to North America;  
  • A wide diversity of ecosystems including alpine, forests, parkland, and grassland; and  
  • The source of 13 major rivers, all of which provide clean, safe drinking water for more than 15 million people.

Yellowstone to Yukon priority areas 

Spanning five American states, two Canadian provinces, two Canadian territories, and the traditional territories of at least 75 Indigenous groups, the Yellowstone to Yukon region encompasses a diverse array of communities. We divide it into 11 priority areas for conservation action.

These areas are based on ground-breaking research on the continental status of grizzly bear populations and the connections between these populations.

Each area functions either as a core habitat or as linkage zones that connect one core to another. Y2Y focuses its efforts on the areas that will help advance the Yellowstone to Yukon vision the most.
