Long-term Impact Assessment of the CEC Monarch Butterfly Conservation Work (1996–2016)
July 16, 2019 2 pages Ecosystems
Since 1996, the Commission for Environmental Cooperation has been actively involved in the conservation of the monarch butterfly (Danaus plexippus), a symbol of trinational environmental cooperation between Canada, Mexico, and the United States. Although interrupted for a few years, CEC efforts to conserve the species intensified after population declines were recorded at overwintering sites in Mexico in 2005 (Rendon-Salinas and Galindo-Leal 2005).
What We Do
We conduct research, provide tools and training, and provide a unique space for decision-makers and the public to engage on environmental policy issues affecting the North American region.
