The NH Butterfly Monitoring Network (NHBMN) is an effort to engage volunteers in counting and identifying butterflies across New Hampshire. Data collected by volunteers can contribute to our understanding of long-term trends in butterfly populations and inform conservation actions for both common and declining species. The NHBMN promotes volunteer participation in formal surveys, as well as the collection of opportunistic data. 

The NHBMN is a collaboration between state agencies, land trusts, conservation organizations, and university partners interested in butterfly conservation. These partner groups and organizations provide regional leadership for the Network. Coordination is provided by NH Fish & Game Department and UNH Cooperative Extension.
