About the CEC

The Commission for Environmental Cooperation (CEC) is an intergovernmental organization that supports the cooperative environmental agenda of Canada, Mexico and the United States to green North America’s economy, address climate change by promoting a low-carbon economy, and protect North America’s environment and the health of its citizens. The CEC is composed of three bodies: a Council, representing the governments of the three member countries; a Joint Public Advisory Committee (JPAC), which advises the Council and serves as a liaison with the public; and a Secretariat, which supports the Council and JPAC and prepares independent reports. The CEC brings together governments, civil society, and businesses, to develop innovative North American solutions to global environmental challenges. Find out more at: <>.

In June 2015, Canada, Mexico and the United States, through the Commission for Environmental Cooperation (CEC), approved a trinational project to improve conservation outcomes for at-risk shorebirds.

The goal was to foster North American conservation opportunities for Semipalmated Sandpipers (Calidris pusilla) and Red Knots (Calidris canutusrufa and roselaari subspecies) by informing, engaging and connecting communities at key sites for these two species, species that have very broad breeding ranges and were identified as key biodiversity indicators for other co-occurring species.

Key outputs of the two-year project Arctic Migratory Birds Initiative (AMBI) – Americas Flyway Action Plan are now available on this website, including a compilation of information on Red Knot and Semipalmated Sandpiper sites of importance in North America, summaries of conservation actions at CEC-supported project sites, and a shorebird outreach and education toolkit.

It is hoped this website will help raise awareness among communities along North America’s Pacific and Atlantic flyways that they steward a shared resource; and that the website will serve to link these communities and facilitate the sharing of shorebird data and conservation strategies and results.

This initiative is undertaken with the financial support of the Government of Canada, through Environment and Climate Change Canada; the Government of the United States of America, through the Environmental Protection Agency; and the Government of the United Mexican States, through the Secretaría de Medio Ambiente y Recursos Naturales. Experts at the Canadian Wildlife Service, the Comisión Nacional para el Conocimiento y Uso de la Biodiversidad (Conabio) of Mexico and the U.S. Fish and Wildlife Service provided guidance on this initiative.
