The Yellowstone to Yukon Conservation Initiative (Y2Y), a project spanning 33 years dedicated to connecting and protecting wildlife habitats from Wyoming to Canada, has been selected as a finalist for Prince William's prestigious Earthshot Prize. The initiative is recognized for its extensive conservation efforts, which include supporting the establishment of 204 wildlife crossings and helping to protect 59 million acres across a vital ecological corridor.

Established in 1991, the Y2Y initiative aims to ensure the long-term ecological health of a vast 3,200-kilometer (2,000-mile) mountain ecosystem, allowing for the unhindered movement of diverse wildlife species. This region, stretching from the Greater Yellowstone Ecosystem in the United States to the Yukon Territory in Canada, is crucial for species such as grizzly bears, elk, wolves, caribou, and wolverines. The project’s efforts are focused on mitigating habitat fragmentation caused by human development, advocating for protected areas, and fostering ecological resilience in the face of environmental changes.

The development of 204 wildlife crossings represents a significant component of the Y2Y strategy. These structures, including underpasses and overpasses, facilitate safe passage for animals across major highways and other infrastructure, thereby reducing wildlife-vehicle collisions and maintaining genetic connectivity between populations. The protection of 59 million acres has been achieved through a combination of land purchases, conservation easements, and advocacy for government-designated protected areas, safeguarding critical habitats and migratory routes.

The Earthshot Prize, founded by Prince William in 2020, recognizes and scales innovative solutions to the world’s most pressing environmental challenges. Y2Y's nomination highlights its long-term, collaborative approach to large-scale conservation. The prize annually awards five winners £1 million (approximately $1.27 million USD) each, along with global recognition and support to further develop and implement their solutions.

The Yellowstone to Yukon Conservation Initiative was co-founded by Harvey Locke, Elizabeth May, and Mike Halleran. Their vision established a framework for cross-border cooperation involving governments, Indigenous communities, landowners, and conservation organizations. The initiative's work demonstrates a sustained effort to preserve biodiversity and promote ecological connectivity across one of North America's most significant wilderness areas.

The selection of Y2Y as an Earthshot Prize finalist brings international attention to its model of regional conservation. The annual Earthshot Prize awards ceremony is anticipated to announce the final winners later this year, potentially providing additional resources and a broader platform for Y2Y's ongoing work to ensure a connected and resilient landscape for wildlife from Wyoming to Canada.
