Be the Super Generation that saves the monarchs
Join the Illinois Monarch Project statewide initiative as we conserve the breeding and feeding habitat of the monarch butterfly and other regional pollinators.
Thanks to your involvement, weâre celebrating major monarch milestones as part of our 10-year progress report. But the work isnât done yet. Read on to learn more about what weâve accomplished and whatâs in store for 2038.
Monarchs in Illinois
The Great Monarch Migration
It takes 2 or 3 generations of butterflies to migrate from the mountains of MichoacĂĄn, Mexico, to the prairies of Illinois in the spring months. By late summer, a âsuper generationâ emerges, equipped to travel an estimated 2,500 miles back to Mexico for overwintering.Â
Illinois offers these iconic butterflies the crucial milkweed resources they require for breeding, along with the nectar plants they rely on for subsistence during their migratory journey.
About the Illinois Monarch Project
Over the past 20 years, the eastern monarch population has faced a significant decline in migratory habitat. The Illinois Monarch Project collaborates with public and private partners, in addition to individuals across the state, to protect and enhance existing habitat and establish new habitat that supports monarch butterflies and other pollinators.
With your help, we can reach our goal of adding 150 million new milkweed stems and other nectar resources to the Illinois landscape by 2038.
Join fellow Illinoisans in fostering a culture of conservation that ensures future biodiversity and flourishing pollinator habitat across diverse urban and rural landscapes in Illinois.

Whether you have a few pots on a porch, or acres of sprawling land, every Illinois resident plays a part in the regeneration of this vital pollinator. Every milkweed stem counts. Every nectar-producing wildflower brings the monarch one step closer to survival. Learn how to make a difference from your own backyard.
As of June 2026, over 4,300 Monarch Waystations, or monarch habitats, were registered with Monarch Watch in Illinois – many of which exist in individual home gardens.

The reciprocal relationship between Illinois producers and monarchs is a thing of beauty. Farmersâ futures depend on thriving pollinator populations. While agriculture industry specialists support the future of monarchs through sound science and research, outreach and education practitioners work closely with the agricultural community to share and encourage best practices for conserving, enhancing, and creating monarch habitat.
Agriculture in the Classroom programming provides pollinator specific education to over 106,000 students and nearly 5,000 teachers across Illinois.

Urban, suburban, and rural communities are home to a range of gathering spaces, from corporate campuses and local businesses, to schools, cultural institutions, and parks. From Chicago to Carbondale, communities are hubs of activity that bring people together to fuel the feeding, breeding, and migration of monarchs.
As of 2026, 75 mayors in Illinois have signed onto the Mayorâs Monarch Pledge.Â

From state lands to land trusts and county forest preserves, natural land managers have a long history of protecting and stewarding the unique natural heritage of Illinois. Through the preservation and restoration of native ecosystems, thereâs room for these natural protectors to make a lasting impact on this incredible species.
Since 2014, over 96,000 acres of new habitat has been added to Illinoisâ protected lands network, providing an estimated 3.8 million milkweed stems.

Imagine traveling across our countryâs highways with no rest stops along the way. Monarch butterflies, one of the great migratory species of our day, face a steep and rapid decline of rest stops along their 2,500 mile journey from Mexico to Illinois. State and local road authorities, electric and gas utilities, and other infrastructure land managers have the opportunity to foster feeding and breeding stations for monarchs along rights-of-way habitat across Illinois.
New mowing guidelines set forth by the Illinois DOT in 2017 resulted in the creation and enhancement of over 80,000 acres of monarch and pollinator habitat throughout the state

Milkweed Mania
Since 2014, weâve already seen an estimated 108 million additional milkweed stems planted across Illinois.
This puts us two-thirds of the way toward our Action Plan goal of 150 million stems planted by 2038.
Catch up on all weâve achieved and whatâs in store with our 10-year progress report.
Monarch Milestones
Illinois adopts the monarch as the state insect. Â
White House establishes the Federal Pollinator Health Task Force; the US Fish & Wildlife Service is petitioned to protect the monarch under the Endangered Species Act.Â
Illinois declares the monarch the Species of Greatest Conservation Need; the Midwest Association of Fish & Wildlife Agencies (MAFWA) begins a 20-year plan for monarch conservation in Illinois.
Illinois surpasses 1,000 registered Monarch Watch Waystations and the Illinois Monarch Project hosts the first statewide Monarch Summit.
Illinois designates milkweed as the state wildflower; MAFWA sets a goal of adding 1.3 billion milkweed stems across critical monarch habitat by 2038.
Illinois Departments of Natural Resources, Agriculture, Transportation, and Environmental Protection sign an agreement committing their support of the Illinois Monarch Project.
Illinois surpasses 2,000 Monarch Watch Waystations, and designates the month of May as âMonarch Monthâ to be observed annually in honor of the state insect.
The Second Monarch Summit launches the statewide implementation of the Illinois Action Plan, with the US Fish & Wildlife Service expected to make a listing decision for the monarch butterfly under the Endangered Species Act.
We did it! 150 million milkweed stems added to the Illinois landscape.
UIC and the Illinois Department of Natural Resources release a 10-year progress report on the status of voluntary monarch conservation efforts; over 108 million new milkweed stems added across Illinois since 2014.
Celebrating 10 Years of Progress
The Illinois Monarch Project 10-year Progress Report presents the first comprehensive assessment of the stateâs progress toward reaching the goals outlined in the Illinois Monarch Action Plan.
Through rights-of-way commitments, agricultural programs, improvements in grassland and protected natural areas, meaningful urban lands contributions and public engagement efforts, the report demonstrates how voluntary conservation relies on diverse participation to actively produce habitat benefits.
With a committed network of partners like yourself, Illinois is wellâpositioned to create lasting, resilient conservation outcomes that ensure monarch butterflies and pollinator habitats continue to thrive far into the future.
