Preserving Plum Island

Will we ever get another chance to save an 840-acre island in Long Island Sound? An island that’s a haven for wildlife, at the joining of two nationally significant estuaries, and part of a chain of islands so rich in ecological diversity that it has received numerous official recognitions from state, federal, and indigenous entities? Sadly, because of a 2009 act of Congress, the federal government put Plum Island on the auction block. Action by dedicated champions in Congress halted that momentum, but a permanent solution for conservation and management of this precious place is still needed.

This is the only chance we will have to protect this critical place. Save the Sound has stepped up. We’ve mobilized citizens in three states, developed a coalition of over 100 varied organizations, filed a federal lawsuit to block the sale based on the Endangered Species Act and the National Environmental Policy Act, worked with your local elected officials to promote Plum’s preservation, and are in the midst of new efforts to ensure Congress takes action to conserve the island’s wildlands.

We lead a mission to save Plum Island, and we need our secret campaign ingredient—YOU—now more than ever. 

Plum Island is like no other

  • Largest seal haul-out in New York
  • Habitat for 220 bird species—nearly one out of four bird species found in North America!
  • Significant ecological communities, including sea turtles, marine eelgrass beds, and rich fish populations
  • Several distinct subtidal marine habitats, as documented in a 2022 report by the New York Natural Heritage Program and InnerSpace Scientific Diving
  • Site of Fort Terry, in use from the Spanish American War until after World War II
  • Plum Island Light, a National Register Historic Site
  • Internationally renowned Plum Island Animal Disease Center

Save the Sound leads the way

We lead the charge to save Plum Island at the local, state, and federal levels. We are fighting to make sure Plum Island remains a sanctuary for wildlife and becomes a place where people can enjoy fishing its waters and walking its beaches.

Save the Sound directs the campaign to save Plum Island, a multi-year, multi-state effort that includes:

  • Coordinating Envision Plum Island, a planning process that included the coalition and 160 stakeholders from diverse fields to develop a vision and plan for the island’s future with broad local and regional consensus. View the report here. To learn more, visit:
  • Successfully supporting bills introduced by Plum Island champions in Congress that repealed the language driving a private sale.
  • Suing two federal agencies for their faulty environmental impact statement. Read about the lawsuit.
  • Coordinating the Preserve Plum Island Coalition, made up of nearly 100 organizations! Learn more and join the coalition at or contact Louise (NY) today.
  • Supporting New York’s 2016 Open Space Conservation Plan. It says New York could acquire 600–700 acres of open space on Plum Island for “wildlife habitat, shoreline preservation and protection of significant cultural resources,” if the U.S. Fish and Wildlife Service does not create a wildlife refuge there. 
  • Urging New York to use all its power under its Long Island Sound Coastal Management Program to block the sale of Plum Island to a private entity, and to support permanent conservation.
