Canada, Mexico, and the U.S. share a wide array of ecosystems, habitats and species. They are also linked by strong economic, social and cultural ties.

To more effectively address priorities of continental significance and boost the concerted efforts of the three countries of the North America bioregion, the Canada/Mexico/U.S. Trilateral Committee of Wildlife and Ecosystem Conservation and Management was established in 1995. The Trilateral Committee is headed by the directors of the Canadian Wildlife Service (CWS), the U.S. Fish and Wildlife Service (USFWS), and the Ministry of Environment and Natural Resources of Mexico (SEMARNAT).
