About Mayors' Monarch Pledge

Mayors and other local and tribal government chief executives are taking action to help save the monarch butterfly, an iconic species whose populations have declined by 90% in the last 20 years. Through the National Wildlife Federation’s Mayors' Monarch Pledge, U.S. cities, municipalities, and other communities are committing to create habitat for the monarch butterfly and pollinators, and to educate citizens about how they can make a difference at home and in their community. Since the monarch's migration spans the United States, Mexico, and Canada, the pledge expanded to these countries through new tri-national partnerships in 2017. There are four steps to taking and implementing the pledge.

1. Take the Pledge

By taking the Mayors' Monarch Pledge, you are committing to both restore habitat in your community and encourage your citizens to do the same. Read the Mayors' Monarch Pledge language and then take the pledge online!

2. Specify Your Actions

We will follow up with the point person specified in the online pledge form and work to identify at least 3 specific actions that your community will initiate in the next year. Mayors who decide to take 8 or more actions will receive special recognition and become a member of the Mayors' Monarch Pledge Leadership Circle and those that take on every single action item will become a Monarch Champion City. Once these specific actions have been identified, communities will report their progress through a simple online survey form. Read the Mayors' Monarch Pledge Action Items and then specify which actions you will take.

3. Take Action

Once you have taken the pledge and specified which actions your community will take over the next year, it’s time to start taking action! Over the next several months, the National Wildlife Federation will be sharing best practices for cities and municipalities through our online resources section, occasional email updates, social media, and webinars. Please refer to our resources section below for more details.

4. Report Progress

Once you have specified your actions and begun to take action we will ask communities to fill out a simple reporting form on an annual basis. The reporting process will only take 5-20 minutes depending on how many action items you are reporting. The data we collect will allow us to track the collective outcomes and impact of our work.

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 U.S. 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.

Participating Cities

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.

CEC CCA CCE LogoThe Commission for Environmental Cooperation (CEC) is a tri-national organization through which the governments of Canada, Mexico, and the United States collaborate, with input from civil society, on the protection, conservation, and enhancement of North America’s environment.
