Tamar Estuary Sites

Site overview: The Tamar Estuary Marine Conservation Zone, a type of Marine Protected Area, is actually located in two separate areas. The total area is approximately 15 km2 and includes the upper area of the Tamar and Lynher estuaries. Both areas are home to saltmarsh and intertidal mudflats; mussel beds have been recorded here. These mussels form a type of reef, as their shells are bonded together with mud and sand, and by the sticky thread or ├óÔé¼┼ôbeards├óÔé¼┬Ø of the mussels. These living reefs are ecologically important as they provide a home for seaweeds and animals including barnacles, winkles and small crabs. The estuaries are also the only known home to smelt, a type of fish, which use the sites for breeding. The sites also acts as a nursery for many other fish species.
