Using Seeds To Propagate And Restore Vallisneria Americana Michaux (Wild Celery) In The Chesapeake Bay, Kenneth A. Moore, Jesse C. Jarvis Dec 2007

Using Seeds To Propagate And Restore Vallisneria Americana Michaux (Wild Celery) In The Chesapeake Bay, Kenneth A. Moore, Jesse C. Jarvis

Reports

Loss of submerged aquatic vegetation (SAV) has been significant in many coastal and estuarine systems such as the Chesapeake Bay where SAV die-offs have been observed in marine, brackish, and freshwater SAV communities (Orth and Moore 1983). Large-scale replanting using whole plants can be cost-prohibitive, and the use of plants taken from wild populations for propagule supply may not be possible or desirable. The use of SAV seeds for restoration has been increasingly demonstrated to be an effective method for replanting large areas of bottom, especially for marine species such as eelgrass, Zostera marina (Pickerell et al. 2005; Orth et …

Performance Of Sills: St. Mary’S City, St. Mary’S River, Maryland, C. Scott Hardaway Jr., W. G. Reay, Jian Shen, Scott Lerberg, Donna A. Milligan, Christine A. Wilcox, Kevin P. O'Brien

Reports

Living shorelines represent a shoreline management option that combines various erosion control methodologies and/or structures while at the same time restoring or preserving natural shoreline vegetation communities. A common living shoreline design in Chesapeake Bay includes a low offshore rock sill to absorb wave energy with an emergent wetland landward of the sill to enhance erosion control, provide critical habitat, and improve water quality condition. This study is part of a larger, ongoing project to (1) evaluate erosion control effectiveness and the sustainability of offshore sill and fringing marsh design and structure, (2) evaluate ecological services (e.g., habitat value, water …

Coastal Maritime Forests In Virginia – Delineation And Distribution, Marcia Berman, Harry Berquist Nov 2007

Coastal Maritime Forests In Virginia – Delineation And Distribution, Marcia Berman, Harry Berquist

Reports

This project had two major goals. The first builds on an earlier effort by the Virginia Department of Forestry, who delineated maritime forests using remote sensing techniques. Their project integrated land use and soils data to generate a map that defines potential boundaries of maritime forest. This study follows an identical approach with two major exceptions. The first is the soils data used in this study is mapped at a much finer scale. The second is this study has a field validation component that reviewed random sites around selected locations to ground-truth the remote sensing output. The Virginia Department of …

Lynnhaven River Virginia Beach, Virginia Shoreline Inventory Report, Marcia Berman, Harry Berquist, Sharon Killeen, Karinna Nunez, Tamia Rudnicky, Daniel E. Schatt, Karen Reay, David Weiss

Reports

The data contained within the Shoreline Inventory is based on a three-tiered shoreline assessment approach. The assessment characterizes conditions that are observed from a small boat navigating along the shoreline. Hand-held GPS units are used to log features. The three tiered shoreline assessment approach reports conditions in three regions: 1) the immediate riparian zone, evaluated for land use; 2) the bank, evaluated for height, stability, cover and natural protection; and 3) the shoreline, describing the presence of shoreline structures for shore protection and recreational purposes. Three GIS coverages are generated. The lynn_lubc coverage contains features related to the land use …


Shallow Water Fish Communities And Coastal Development Stressors In The Lynnhaven River, Donna M. Bilkovic, David Stanhope, Kory Angstadt Aug 2007

Shallow Water Fish Communities And Coastal Development Stressors In The Lynnhaven River, Donna M. Bilkovic, David Stanhope, Kory Angstadt

Reports

Coastal development pressures in the Mid-Atlantic have been attributed to significant negative impacts to aquatic ecosystems. The Lynnhaven River watershed, located in the southernmost extent of the Chesapeake Bay and encompassing Virginia Beach, is an example of a shallow-water tidal system under intense development pressure that is confronted with multiple and often conflicting coastal management issues. Rapid development in and around the City of Virginia Beach over the past few decades has led to the loss of natural buffers and habitat (e.g. oyster, wetlands and seagrasses), increased sedimentation, and degraded water quality. The Lynnhaven Ecosystem Restoration Project, led by U.S …


The Stability Of Living Shorelines - An Evaluation, Center For Coastal Resources Management, Virginia Institute Of Marine Science, Marcia Berman, Harry Berquist, Julie Herman, Karinna Nunez Jun 2007

The Stability Of Living Shorelines - An Evaluation, Center For Coastal Resources Management, Virginia Institute Of Marine Science, Marcia Berman, Harry Berquist, Julie Herman, Karinna Nunez

Reports

This project set out to strengthen arguments that living shorelines were a viable and preferred method of erosion control along much of the Chesapeake Bay shoreline. Using statistical tests and data that describe shoreline and environmental condition along tidal shoreline, the study found that indeed marshes are frequently associated with stable shoreline and therefore recommending living shoreline treatments to manage erosion problems was a reasonable strategy that warranted strong consideration. Additional tests revealed a lower occurrence of marshes when traditional erosion control structures like bulkheads and revetments were present. This confirms these structures can permanently impact the growth of tidal …


Monitoring Relative Abundance Of American Shad In Virginia Rivers 2006 Annual Report, John E. Olney, Kristen Delano Walter Apr 2007

Monitoring Relative Abundance Of American Shad In Virginia Rivers 2006 Annual Report, John E. Olney, Kristen Delano Walter

Reports

Concern about the decline in landings of American shad (Alosa sapidissima) along the Atlantic coast prompted the development of an interstate fisheries management plan (FMP) under the auspices of the Atlantic States Marine Fisheries Management Program (ASMFC 1999). Legislation enables imposition of federal sanctions on fishing in those states that fail to comply with the FMP. To be in compliance, coastal states are required to implement and maintain fishery-dependent and fishery-independent monitoring programs as specified by the FMP. For Virginia, these requirements include spawning stock assessments, the collection of biological data on the spawning run (e.g., age-structure, sex ratio, and …

Integrated Guidance For Tidal Shorelines, Center For Coastal Resources Management, Virginia Institute Of Marine Science Jan 2007

Integrated Guidance For Tidal Shorelines, Center For Coastal Resources Management, Virginia Institute Of Marine Science

Reports

Tidal shorelines are the site of complex interactions between terrestrial and aquatic systems. These areas have values that far outweigh their relative size in the larger ecosystem. They are exceptionally important habitat for a wide variety of organisms, some living primarily on land, others that live in water, and a few that are found only in the intertidal zone between land and water. Tidal shoreline systems provide important filtration capacity for materials carried in runoff and groundwater. They are uniquely valued by human users of coastal systems. In Virginia, tidal shoreline systems are managed in small segments, rather than as …
