Localized Species Maps

• Mass Audubon’s Ecological Extension Service completed a detailed inventory of invasive species on the Assabet River National Wildlife Refuge (ARNWR), incompassing 2,200-acres.  The work resulted in the following maps which are directly informing management decisions.  Maps for specific invasive species:
• Black Locust
• Common Buckthorn
• Glossy Buckthorn
• Honeysuckle
• Japanese Barberry
• Combined species

• Autumn Olive at Drumlin Farm  -  This map shows sample data from work completed at Mass Audubon’s Drumlin Farm Wildlife Sanctuary. The Sudbury Foundation supported the development of a GPS-based mapping tool and a website to display information collected by CISMA partner staff and volunteers.
