Top Ten Invasive Species

The Invaders of the New England Coastline is an innovative campaign dedicated to empowering volunteer “citizen scientists” to more effectively slow the spread of harmful invasive species and reduce their economic damages. Through partnerships with the Massachusetts Office of Coastal Zone Management and USGS, and with assistance from Salem Sound Coastwatch, the data collected by volunteers will be added to a national database that will be used to track the spread, as well as the eradication and control of, invasive species.

We depend on feed back from you to make this a success. Please let us know how we can improve this program.
