The Long Island Sound Collaborative is a diverse group of funders with missions that include the protection and restoration of the Long Island Sound. Initially created to align grantmaking around the protection and restoration of the Sound, the Collaborative has focused on understanding the myriad of issues facing this tidal estuary and identifying possible solutions. The goal is to have a greater impact by pooling our knowledge, expertise, relationships, and funding. These efforts have resulted in annual Long Island Sound Report Cards and an ongoing Unified Water Study initiative, which have subsequently been funded by the Environmental Protection Agency. Today, the collaborative continues its commitment to support projects that address pressing challenges and provide for a healthy, productive, and resilient Sound now and into the future.
