The Mayors’ Monarch Pledge is a tri-national initiative to encourage mayors and other local government chief executives to take community-wide actions to help save the monarch butterfly. Following its launch by the National Wildlife Federation in the United States in September 2015, mayors across the US took the pledge and began taking actions to help save the monarch butterfly. Within 18 months, over 300 cities had taken the Mayors’ Monarch Pledge across the United States.

While the pledge was originally designed for municipalities in the United States, the pledge was expanded in 2017 to Canada and Mexico through the Commission for Environmental Cooperation.


Trinational Mayor's Monarch Pledge

Monarch butterflies “overwinter” in the oyamel fir forests of the Sierra Madre Mountains west of Mexico City. In the spring they head north, mate and lay eggs on milkweed in the northern states of Coahuila, Nuevo León, and Tamaulipas in Mexico and Texas in the United States. Four additional generations will spread north across the northern United States and southern Canada. All three countries play a critical role in saving the monarch butterfly!Trilateral collaboration is critical for a species like the monarch butterfly whose eastern population’s (east of the continental divide) multigenerational migration spans the three countries.
