Conserving Borderline Species: A Partnership between the United States and Canada

Wild species know no borders. Many inhabit ecological regions that stretch across political boundaries. Canada and the United States share several ecological regions- forests, mountain ranges, the coastal plains, the Great Plains, the Great Lakes, and the Arctic tundra. A great number of wild species, from western prairie fringed orchids to grizzly bears, occur in both countries, or migrate between them.
