Why do we tag monarchs?
Every fall, monarchs across the eastern US begin their journey south to their overwintering grounds in Mexico. Some travel hundreds, even thousands, of miles to get there. So, why tag them?
When we tag a monarch, we give it a small tag with a unique identification number. If that monarch is found again, researchers can see where it was tagged and where it was found. This helps us learn more about how far they travel, the routes they take, and where they stop along the way.
The information helps researchers better understand monarch migration and where habitat is most important. This is especially important as monarch populations continue to face challenges. Monarchs are currently being proposed for protection under the Endangered Species Act, making research and monitoring more important than ever.
All of our monarch work is led by Charlie Logsdon. Charlie runs our tagging program and spends countless hours in the field collecting migration data, photographing monarchs, and sharing what he’s learned with others.
