Marine Invasives Monitoring Information Collaborative (MIMIC)
The National Park Service and the Boston Harbor Islands Partnership are developing a long-term monitoring program of invasive marine organisms in the Boston Harbor Islands. The monitoring program, called MIMIC (Marine Invasive Monitoring Information Collaborative), relies on a network of trained volunteers who are working to identify new invaders before they spin out of control, and to better understand the behavior of established species.

If you are interested in volunteering, please review the documents below and register for a program on Stewardship Saturdays. For more information on aquatic invasive species, go to the Aquatic Invasive Species Program on the Massachusetts Office of Coastal Zone Management website.
