    General Information on Aquatic Invasive Species

    • Defending Massachusetts Against Biological Invaders - This article on page 33 of the Summer 2002 Coastlines pdf format of Coastlines 2002 - Hurricanes
file size 4MB provides an overview of the marine aquatic species issue.
    • State of the Gulf of Maine Report - Marine Invasive Species - This paper, written by CZM and published by the Gulf of Maine Council on the Marine Environment, provides a review of established marine invasive species in the Gulf of Maine, and describes impacts, vectors, emerging threats, and management responses.


    • Implementing Rapid Response to Aquatic Nuisance Species in the Northeast: Key Components of a Successful Program - This document presents proceedings from a May 2005 workshop of the Northeast Aquatic Nuisance Species Panel that offered in-depth information about the key aspects of a successful early detection and rapid response program by featuring presentations on developing a rapid response protocol, model state legislation, obtaining emergency powers, getting legislation passed, alternatives to legislation, and rapid response protocols for other sectors.
    • Managing Seaweed Accumulations on Recreational Beaches pdf format of Seaweed Management Guidance
file size 2MB - This guidance published by CZM in 2013 was developed to help local officials and beach managers effectively address seaweed accumulations on recreational beaches while protecting coastal resources. It focuses on how seaweed is a natural and important part of the marine ecosystem, but when accumulations occur on recreational beaches, conflicts can arise that need to be addressed.
    • Massachusetts Aquatic Invasive Species Management Plan - This plan, released in 2002, outlines a five-year strategy to manage threats from aquatic invaders. Major components of the plan include a description of existing state and federal authorities and programs, a focus on the impacts of invasive species and management priorities, management objectives and actions, and an implementation timeline.
    • Rapid Response to Aquatic Nuisance Species in the Northeast: Developing an Early Detection and Eradication Protocol - This document presents proceedings from a May 2003 workshop of the Northeast Aquatic Nuisance Species Panel that laid the groundwork for rapid response planning in the region through the presentation of a series of rapid response case studies and other rapid response planning efforts from around the country.


    • Identification Cards - To help detect and monitor marine invasive species, CZM funded the development of 23 species identification cards for marine invaders in the Gulf of Maine. These cards were created by Salem Sound Coastwatch.
    • Non-Native Seaweed in Massachusetts pdf format of non-native-seaweed-fact-sheet.pdf
file size 1MB - Published by CZM in 2013, this fact sheet summarizes information on invasive seaweed species in Massachusetts, their ecology, and potential impacts to the marine ecosystem and economy.
    • Rock Snot Brochure pdf format of Didymo Brochure
- In November 2007, CZM, the Department of Conservation and Recreation, and the Massachusetts Aquatic Invasive Species Working Group issued an alert for the invasive freshwater diatom, Didymosphenia geminata, otherwise known as Didymo or Rock Snot. This alga has the potential to blanket streambeds in a thick mat, leading to a loss of habitat for fish and invertebrates and making swimming and fishing undesirable. Didymo has been discovered in New Hampshire, Vermont, and New York rivers, and the working group is seeking the public's help to keep this invasive species out of Massachusetts waters.


    Rapid Assessment Surveys


    • Codium Up, Eelgrass Down: Invasives Impact Buzzards Bay - This article on page 59 of the 2007 Coastlines pdf format of Coastlines 2007
file size 38MB discusses the impact of the invasive Codium alga on eelgrass habitat.
