Located just west of the City of Saint John, the Musquash Estuary is one of the most ecologically significant areas in Atlantic Canada. Identified as the last fully functioning estuary in the Bay of Fundy region, conservation of this site is critical to the health of the larger Bay of Fundy ecosystem. The estuary contains all of the habitat types found in the greater Bay of Fundy, from cobble and sand beaches to mudflats, salt marshes and coastal forests.
