Illinois Butterfly Monitoring Network (IBMN)
The Illinois Butterfly Monitoring Network (IBMN) is a model for butterfly monitoring nationwide. It now monitors all sites within Illinois—including inside of the City of Chicago.
IBMN is a diverse group of volunteers who, since 1987, have identified and counted butterflies, running more than 3,000 routes on sites in Illinois. These investigators collect data that are valuable to scientists, researchers and land managers in evaluating how restoration practices and other changes affect butterfly populations.
