        WHO WE ARE

        The Piscataqua Region Estuaries Partnership (PREP) is a collaboration-driven local organization and National Estuary Program. We work with towns, researchers, and local organizations to offer scientifically-informed solutions to improve the health of our waters. We offer grant funding, process facilitation, collaborative workshop development, and outreach (like community building and project guidance). We also conduct habitat restoration to help our ecosystem bounce back, monitor our estuaries, and publish publicly available data about health trends that impact the entire watershed. Through region-wide collaboration and a non-regulatory approach, we’re here to tackle big clean water challenges.

        Our 2025-2035 Piscataqua Region Comprehensive Conservation and Management Plan which contains 79 action plans that provide a roadmap to protecting and restoring the Great Bay and Hampton-Seabrook estuaries.
