My site during mid-July

The Monarch Larva Monitoring Project (MLMP) is a citizen science project involving volunteers from across the United States and Canada in monarch research. It was developed by researchers at the University of Minnesota to collect long-term data on larval monarch populations and milkweed habitat. The overarching goal of the project is to better understand how and why monarch populations vary in time and space, with a focus on monarch distribution and abundance during the breeding season in North America.

As an MLMP volunteer, your contributions will aid in conserving monarchs and their threatened migratory phenomenon, and advance our understanding of butterfly ecology in general.

Does your heart soar and fill with wonder when a monarch flutters by? Are you concerned about the monarch population or wild species in general?

The Monarch Larva Monitoring Project (MLMP) is an exciting way for monarch and nature enthusiasts to contribute basic knowledge about monarch population dynamics, and foster monarch and habitat conservation. Help from citizens across the country gives scientists a far bigger picture of the health of the monarch population. Your involvement is the key!

MLMP volunteers are always learning. During Nature Center training sessions, volunteers learn about monarch biology, practice monitoring and data entry protocols, and receive all of the materials necessary to conduct monitoring. Or, you can learn on your own with our online directions. Learning to monitor is only the beginning; your observations and data collection activities will invoke awareness of and curiosity about the local environment. Volunteers communicate with monarch scientists with their questions and concerns through email. All data are compiled by scientists and made available to volunteers. So, you’ll see your direct contribution to increased understanding of the monarch population.

Monitoring can be done alone or with others. The MLMP is a terrific way to introduce young adults to field science and the love of nature. Monitoring is also a passion to share with a friend or relative.

The best reason to participate in the MLMP is your enthusiasm: about monarchs, nature, conservation, and continued learning. Please consider signing up today, contact us for further information on how to become an MLMP volunteer, or check to see if there will be a training session at a Nature Center near you. We hope to hear from you!
