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

Monarch Conservation CoverMonarch 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 National Wildlife Federation's 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.
