“The vision for the Sound is of waters that are clean, clear, safe to swim in, and charged with life. It is a vision of waters nourished and protected by extensive coastal wetlands, by publicly accessible, litter-free beaches and preserves, and of undeveloped islands. It is a vision of abundant and diverse wildlife, of flourishing commercial fisheries, of harbors accessible to the boating community, and of a regional consciousness and a way of life that protects and sustains the ecosystem.”

—Vision statement from the 2015 Comprehensive Conservation and Management Plan (CCMP)

Go to the overview page of the Our Plan section to find out what our partners are doing to implement the CCMP and how our goals are being measured and tracked.


Themes and Goals of the CCMP

To fulfill the vision of a restored and protected Long Island Sound the partner agencies of the Long Island Sound Study in 2015 revised its Comprehensive Conservation and Management Plan. The Plan seeks to achieve  four primary goals under four  themes:

  1. Clean Waters and Healthy WatershedsImprove water quality by reducing contaminant and nutrient loads from the land and the waters impacting Long Island Sound.
  2. Thriving Habitats and Abundant WildlifeRestore and protect the Sound’s ecological balance in a healthy, productive, and resilient state for the benefit of both people and the natural environment.
  3. Sustainable and Resilient CommunitiesSupport vibrant, informed, and engaged communities that use, appreciate, and help protect Long Island Sound; and.
  4. Sound Science and Inclusive ManagementManage Long Island Sound using sound science and cross-jurisdictional governance that is inclusive, adaptive, innovative, and accountable.

Ecosystem Targets

The 2015 CCMP also sets ambitious, but achievable, long-term targets for the Sound. These ecosystem targets are intended to drive progress toward attaining CCMP goals. Measuring, tracking, and reporting environmental indicators of each ecosystem target will provide information to assess progress and refine and adapt management as needed. The ecosystem targets are described below in pdf documents (note: there are no ecosystem targets for theme 4):

1. Ecosystem targets for Clean Waters and Healthy Watersheds

2. Ecosystem targets for Thriving Habitats and Abundant Wildlife

3. Ecosystem targets for Sustainable and Resilient Communities

  • The 2015 CCMP  is available to read in the media center of the Long Island Sound Study website. It includes chapters on each of the four themes with a list of the outcomes, objectives, strategies and implementation actions needed to achieve the goals and meet the ecosystem targets.
  • The Implementation Actions are also described in detail in supplemental documents that are posted in the media center.  Each “IA” was developed as a five-year action (2015-2019) to be updated every five years  to allow for adaptive management and inclusion of emerging scientific and technological advances.

Did You Know?

Pages from LISS_CCMP_FIN_Sept3_LOWRES-2Estuaries such as Long Island Sound are where rivers meet the sea

These valuable coastal bodies of water face many threats, including development and the impacts of sea level rise. In the US, the Long Island Sound, through the Long Island Sound Study, is one of 28 estuaries managed through EPA’s National Estuary Program to safeguard the health of these ecosystems.
