Invasive species are organisms that are introduced to a new location by human activity and can harm the environment, economy, or public health.​ The Massachusetts Office of Coastal Zone Management (CZM) Marine Invasive Species Program promotes understanding, effective monitoring, and management of these species.

Program Priorities

The CZM Marine Invasive Species Program focuses on:

  • Rapid Assessment Surveys - Every few years, CZM coordinates teams of scientific experts to visit marinas in New England to collect and accurately identify marine organisms to detect new marine invaders and document regional patterns of established invaders.
  • Volunteer Monitoring with the Marine Invader Monitoring and Information Collaborative (MIMIC) - Organized by CZM, MIMIC brings together volunteers and scientific experts to monitor for marine invasive species along the New England coast.
  • MIMIC Story Map - This story map provides photos and descriptions of species monitored, maps of where each species has been observed, and additional information.
  • Marine Invasive Species Identification Cards - These identification cards provide information on 18 common invasive species in New England monitored by MIMIC.
  • Publications - This page includes an annotated listing of all CZM publications related to marine invasive species, covering these topic areas: general information, management, identification, monitoring, rapid assessment surveys, impacts, and prevention.
