Monitoring of Thin-Layer Placement of Material Dredged from Bogues Bay Channel in Virginia This project involves assessment of the impacts of spray dredging with disposal onto intertidal salt marshes in the Chincoteague Bay area. Plant communities and dredged material placement will be monitored over several years to develop management guidance for potential wider use of this disposal method. This project is the first phase of the study and incorporates the preliminary survey work and the initial post dredging followup.
Monitoring the Active Replenishment of Subsiding Habitat (MARSH) project This project is an ongoing study of the Lee, Hill, and Sweet Hall marshes in the Pamunkey River. The study focuses on the documentation of the relationship between marsh surface elevation and the marsh plant community. The project includes experimental manipulation of the study sites involving a variety of methods for raising the elevation of the marsh. Evaluation of the potential for controlling the composition of the marsh plant community by incremental additions of material to the marsh surface is underway. Other studies include the community structure of birds, fish, insects, and benthos as well as detailed water quality and elevation monitoring.

MARSH Project Newsletter Scientists at VIMS are studying the effect of spray dredging a thin layer of material on the marsh surface in three locations. At the same time, other smaller scale experiments involving Koir logs and mesh were installed to test sediment trapping effectiveness.
Tulloch Ditching This publication investigates tulloch ditching or the practice of digging drainage ditches in wetlands with careful removal of the excavated materials from the wetland.
Marina Suitability The tidal waters of Virginia were divided into 28 tiles for publication purposes. For each geographic boundary defined by a tile, there is one map for each major category: habitat, water quality, and design. A fourth map represents the cumulative landscape assessment of all three major criteria evaluated together.
