General Habitat

Areas of Critical Environmental Concern


Salt Marsh


  • Gaining Ground: Defining Priority Research for Resilient Salt Marshes (PDF, 336 KB) - As co-lead of the Salt Marsh Working Group (SMWG), CZM helped to facilitate the identification of research priorities to support collaboration and research that promotes resilient salt marsh habitat now and into the future. SMWG released this summary document to communicate these priorities and to inspire coordinated, transdisciplinary discussion and action around the complex and intersecting challenges of salt marsh management and resilience. See Salt Marsh Working Group for additional information.
  • Managing Seaweed Accumulations on Recreational Beaches (PDF, 2 MB) - 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.
  • Non-Native Seaweed in Massachusetts (PDF, 2 MB) - 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.
  • Essential Fish Habitat (EFH) Assessment Gloucester Harbor, Massachusetts (PDF, 1 MB) - Prepared by the Maguire Group Inc. under contract to CZM as part of the dredged material management planning process, this 2001 publication was prepared for use in determining the potential impact of pending or future projects within Gloucester Harbor on the existing fisheries resources.
  • Gloucester Harbor Characterization Report: Environmental History, Human Influences, and Status of Marine Resources (PDF, 1 MB) - This 2004 report describes human and natural resources, discusses the environmental history of development and human influences, characterizes current understanding of environmental quality, examines lobster fishing and lobster population structure, investigates fish community structure, and describes seafloor habitat in Gloucester Harbor.
  • Massachusetts Aquatic Invasive Species Management Plan (PDF, 2 MB) - This plan, prepared by CZM in 2002 on behalf of the Massachusetts Aquatic Invasive Species Working Group, outlines a five-year strategy to manage threats from aquatic invaders.
  • BLOG: Not from Around Here - Green Crabs (originally posted on the EEA Mass Great Outdoor Blog on August 22, 2014) - A CZM intern explains her experience participating in a summer field project surveying green crab populations in the salt marsh.
