Mayors' Monarch Pledge

Mayors and other local 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, cities and municipalities are committing to create habitat and educate citizens about how they can make a difference at home. There are four steps to taking and implementing the pledge.

San Antonio, TX

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 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 take 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. 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 in English or Spanish 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, NWF 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 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 a quarterly basis. The reporting process will only take about 5 minutes and the data we collect will allow us to track the collective outcomes and impact of our work.

The Mayors' Monarch Pledge is an effort to engage mayors (or the principal leader of any city, town, county or HOA) in monarch butterfly conservation. Mayors that take the pledge will receive recognition on NWF’s website. If your mayor is not already on the list of signatories, please take action to get them involved!

Research Your City

If your mayor has not already taken the pledge, then you should do some online research about your city to see if they are currently implementing efforts related to monarchs, pollinators, natural resources, wildlife, sustainability or beautification. The best place to start is your city’s website or social media page(s) like Facebook and Twitter. You can also research what local non-profits are doing in this space – they could be excellent allies in your outreach. Examples include local garden clubs, Keep America Beautiful Affiliates, Wild One Chapters, NABA Butterfly Clubs and other local entities of the Million Pollinator Garden Network or the Monarch Joint Venture.

Reach Out to Your Mayor:

Depending on the size of your community, you may know or have easy access to your mayor. In larger cities, you may wish to first connect with municipal leadership such as the city manager, sustainability director or director of parks and recreation. Many of these contacts can be tracked down through the city website or directory.

Send an email to your mayor or these leadership staff and ask them to sign the Mayors' Monarch Pledge.  You can also request a meeting to discuss the pledge.

Through the Mayors' Monarch Pledge, the National Wildlife Federation seeks to share best practices and lessons learned for each of the 25 potential actions that mayors can take for the monarch butterfly. This page includes links to model polices and case studies of what mayors are doing for monarchs. Please also check out the “open” Facebook Group for real time sharing about the pledge. You can submit a best practice by posting to the Facebook Group or by emailing mayorsmonarchpledge@nwf.org.

Monarch Conservation in America's Cities: A Solutions Guide for Municipal Leaders

This guide is intended for mayors, local government chief executives, municipal staff and others that want to take action to help save the declining monarch butterfly in their community. This guide provides case studies and shares innovative best practices that can be replicated by municipalities across the nation. It includes model language for proclamations, ordinances and other best practices. By learning from one another and understanding what has worked (and what hasn’t) cities can more effectively and more quickly take action and make a difference for the monarch (and other pollinators too).

​Mayors are issuing proclamations to help educate the public about the decline of the monarch butterfly and what citizens can do to take action. Proclamations have been issued on the day mayors take the pledge or other significant national or local days ranging from National Pollinator Week to the date of a local monarch butterfly festival.

​Abandoned Lots:

Most municipalities have abandoned or vacant lands in their communities. These lands can be temporarily or permanently converted to monarch butterfly habitat. These habitats could be managed to produce milkweed seeds and plants for distribution at native plant sales or other events.

Austin, Texas:

This Wildlife Promise blog summarizes the recent actions of Mayor Steven Adler and the City of Austin and includes direct links to the May 2015 proclamation directing the city to plant more milkweed on its 27,000 acres of public lands and 500 municipal buildings.

St. Louis, Missouri:

This blog summarizes many of the initiatives underway in St. Louis, including Mayor Francis Slay’s Milkweed for Monarch program launched in 2014 that is continuing to grow today.

Northville, Michigan:

Like many smaller cities and towns, Northville’s noxious weed ordinance had not been updated in many years.  Under the town’s old ordinance, dating back to 1962, milkweed was specifically prohibited. Northville passed an amendment to the noxious weed ordinance to adopt the state of Michigan’s listing of noxious and poisonous weeds which does not include milkweed on the noxious plant list. Northville intentionally tied their ordinance to the state guidelines because the state lists are updated on a more regular basis based on the best and most recent science. Cities that might wish to consider this approach should visit the U.S. Plant Database, which includes a helpful list of state noxious plant lists and policies.

Ordinance Language

Noxious and poisonous weeds means all species identified in the State of Michigan’s noxious weeds, and the restricted noxious weed list available from the Michigan Department of Agriculture and Rural Development, as established under Act 329 of 1965.
