The Oyster Recovery Partnership (ORP) and the Severn River Association (SRA) are seeking the community’s support to plant a total of 50 million water-filtering oysters in the Severn River this summer. The fundraising campaign, Operation Build a Reef, presents a unique opportunity for the public to purchase bushels of juvenile oysters to further boost already-scheduled oyster reef restoration efforts taking place this July.

“Operation Build a Reef serves as an exciting opportunity for residents to make a real, tangible difference in the health of their local waterway,” said ORP Executive Director Stephan Abel. “With the help of Severn River friends and supporters, we can take advantage of the resources already being devoted this large scale oyster reef project and maximize the amount of oysters the river will receive.”

Earlier this year, the Maryland Department of Natural Resources contracted ORP to produce and plant 40 million oysters onto a carefully selected oyster reef in the Severn River, a 13-acre protected sanctuary between the Naval Academy and Severn River bridges.

The plantings, slated to begin in mid-July and take place over several days, are the largest the Severn River has seen in nearly a decade. ORP and SRA hope to amplify these efforts, and have set a goal to plant an additional 10 million juvenile oysters in the Severn River for a total of 50 million.

“The department supports innovative partnerships and projects, such as the one between the Oyster Recovery Partnership and Severn River Association, aimed at putting more oysters in the Bay and its tributaries,” Natural Resources Secretary Mark Belton said. “Reef building and construction are an essential part of the state’s commitment to oyster restoration, and complements and enhances our existing efforts.”

To reach the 50-million oyster goal, the organizations are asking local residents and businesses to purchase bushels of spat on shell (baby oysters) at Every donation will directly support the production, transport and planting of juvenile oysters in the Severn River. Each bushel contains approximately 2,600 spat that will grow, reproduce and provide critical water-filtering and habitat services.

“SRA and ORP are taking this bold step to repopulate the Severn River because our river and creeks are hurting,” said SRA President Lynne Rockenbauch. “We just suffered through two algae blooms, a red mahogany tide and a toxic green tide all at the same time. To make sure we can fish and swim in our river and creeks, we need to take action now. That’s why we’re investing in oyster restoration ̶ to take advantage of the oyster’s remarkable ability to clean and filter up to 50 gallons of water a day.”

Maryland’s large scale oyster planting projects typically take place on the Eastern Shore as part of the 2014 Chesapeake Bay Watershed Agreement, which calls for restoration of native oyster habitat and populations in 10 Maryland and Virginia tributaries by 2025.

In this instance, ORP’s planting vessel, the Robert Lee will journey beyond its usual planting sites in the Little Choptank and Tred Avon rivers. The donated spat on shell will be added to the vessel at the University of Maryland Center for Environmental Science Horn Point Oyster Hatchery located in Cambridge, Maryland, and make its way to the Severn River in Annapolis on the tentatively scheduled dates: July 16, 18, 23 and 30.

“This joint effort will help strengthen our Bay’s natural filtration system and further assist in our efforts to clean up Anne Arundel County’s more than 530 miles of majestic shoreline,” said Anne Arundel County Executive Steve Schuh. “I encourage every citizen to do their part to restore our oyster population.”
