Oyster Restoration in the Tred Avon River

Partners including the Maryland Department of Natural Resources, National Oceanic and Atmospheric Administration, U.S. Army Corps of Engineers Baltimore District, and Oyster Recovery Partnership are teaming up on a project to restore native oysters to the Tred Avon River on Maryland's Eastern Shore. The project includes:

  • Developing a Tributary Plan for when and where restoration will occur, based on scientific analysis.
  • Enhancing existing oyster reefs with more oysters and building new reefs to grow the native oyster population.
  • Monitoring the health of the rivers by deploying observation buoys and profilers, which can track water quality throughout the water column.
  • Researching how fish—including tracking how many and what species—use oyster reefs as habitat, before, during and after oyster restoration projects. This includes funding research to be conducted by academic institutions in our area.

Building and enhancing oyster reefs is a complex process that involves comprehensive studies before, during, and after construction efforts. Using scientific analysis developed with cutting-edge sonar equipment, the Maryland Interagency Oyster Workgroup developed the "Blueprint" for oyster restoration in the Tred Avon River; this document describes when and where reefs will be constructed or enhanced. An important part of the Blueprint is maps that show where shell or granite substrate and/or oyster seed are proposed to be placed. 

Citizen input on oyster restoration in the Tred Avon River is welcomed. The Maryland Interagency Oyster Workgroup hosted an open house on Thursday, November 7, 2013, at the NOAA Environmental Science Training Center at the Cooperative Oxford Lab where the public was invited to learn about and comment on concepts for oyster restoration in the Tred Avon.
