The area of the proposed Teck Frontier mine overlaps with critical habitat for wildlife and species at risk, and captures the convergence of four major migratory bird flyways

The Frontier poses serious threats to the almost one million migratory birds that fly over the region, species at risk that depend on intact boreal forest habitat, and downstream waters of the Athabasca River.

It threatens to destroy large portions of habitat for one of the only free-roaming disease-free herds of Wood Bison and it lies directly along the migration route for the only wild population of endangered Whooping Crane as they head to Wood Buffalo National Park to breed.

Degrading the habitat that sustains these species will likely jeopardize their recovery, and proposed mitigation measures are unlikely to address these adverse effects; and contributing to a loss of food security for local Indigenous communities.
