The Integrated Monarch Monitoring Program (IMMP) is a national program to collect milkweed, nectar plant, and monarch use data from a variety of land-use types and regions. This information is vital to shaping our understanding of how monarchs interact with their environment, documenting conservation efforts, and tracking the population and its habitat as they change over time. The Monarch Joint Venture (MJV) is a partnership of federal and state agencies, non-governmental organizations, businesses and academic programs working together to protect the monarch migration across the United States.
