Science in Action...

Maine Natural History Observatory is a nonprofit organization established in 2003 to help increase knowledge about Maine's flora and fauna. Our mission is to collect, interpret, publish, and archive information on Maine's plants and animals. To pursue this mission, we work collaboratively with numerous organizations, agencies, and individuals with a strong interest in Maine's natural history.  Please consider making a donation or becoming an MNHO member to support local, impartial natural history research in the wonderful state of Maine.
