ERDC seeks applications for: Assessment of Secondary Production of Restored Submerged Aquatic Vegetation Beds in the Lynnhaven River, VA

B. Background

The Lynnhaven River, Virginia, is the southernmost tributary of the Chesapeake Bay. Its watershed lies mostly within the bounds of the heavily urbanized City of Virginia Beach. As part of the Lynnhaven River Basin Ecosystem Restoration Project, a joint U.S. Army Corps of Engineers (USACE) and City of Virginia effort, a multi-phase submerged aquatic vegetation restoration effort is currently underway. Submerged aquatic vegetation (SAV) has suffered extensive losses in many regions of the world, including the Chesapeake Bay. A pilot study started in 2021 and has successfully established a number of small, mixed species beds of SAV consisting of two species, eelgrass (Zostera marina) and widgeongrass (Ruppia maritima). The project will estimate overall ecosystem benefits by calculating the secondary production of the newly restored SAV beds.

C. Program Description/Objective:

The objectives are to monitor and estimate secondary production at the restored SAV beds, plus compare secondary production associated with the two SAV species habitat patches and to control sites in the Lynnhaven River. This should be done by sampling of all epifauna, infauna, and motile larger fauna within the SAV beds and at several unvegetated control sites outside the SAV beds with similar bottom conditions (sand to silty sand).
