Living Shoreline Design Guidelines For Shore Protection In Virginia’S Estuarine Environment, C. Scott Hardaway Jr., Donna A. Milligan, Karen Duhring Sep 2021

Living Shoreline Design Guidelines For Shore Protection In Virginia’S Estuarine Environment, C. Scott Hardaway Jr., Donna A. Milligan, Karen Duhring

Reports

The Chesapeake Bay has about 6.5 million people living in its coastal counties and much of the shoreline is privately-owned. For communities along the shore, the continual shore retreat may be a problem. When land along the shore show signs of erosion, property owners tend to address it.

These guidelines are meant to address the need to educate consultants, contractors, and other professionals in the use of living shoreline strategies. It provides the necessary information to determine where they are appropriate and what is involved in their design and construction. The guidelines focus on the use of created marsh fringes …

Evaluation Of Private Landowner Intention To Create Early Successional Habitat In Virginia's Appalachian Region, Hannah M. Coovert Jan 2019

Evaluation Of Private Landowner Intention To Create Early Successional Habitat In Virginia's Appalachian Region, Hannah M. Coovert

Theses and Dissertations

As human land uses continue to expand rapidly across the landscape, the management practices of private landowners are an essential part of effective conservation of biodiversity. Conservation of early successional habitats (ESH) and the species that depend on them is a priority in the eastern United States, and efforts to create more ESH on private lands has primarily focused on forest landowners and the harvesting of timber. Private lands with significant pasture cover in a forested landscape present an additional opportunity to create and maintain ESH, yet our understanding of landowner values and attitudes about management strategies in pastures (i.e., …

A Comparison Of Riparian Characteristics And Resulting Water Quality In Restored Agricultural Systems, Amanda Y. Crandall May 2017

A Comparison Of Riparian Characteristics And Resulting Water Quality In Restored Agricultural Systems, Amanda Y. Crandall

Senior Honors Projects, 2010-2019

Agronomic land use and urbanization are the leading causes of water quality decline within streams of the Shenandoah Valley. Implementation of riparian buffer zones is a common, beneficial approach to initiate restoration of negatively affected waterways. In the Commonwealth of Virginia, the Conservation Reserve Enhancement Program (CREP) assists landowners in repairing natural habitat through the provision of cattle fencing and reintroduction of hardwood trees, native warm season grasses, and shrubs. We analyzed seven CREP restored sites of varying time since restoration (5-15 years) to determine the effects of time, land use, and riparian zone characteristics on water quality. The Virginia …

Shoreline Evolution: City Of Chesapeake, Virginia Elizabeth River Shorelines Data Summary Report, Donna A. Milligan, Christine Wilcox, C. Scott Hardaway Jr. Aug 2016

Shoreline Evolution: City Of Chesapeake, Virginia Elizabeth River Shorelines Data Summary Report, Donna A. Milligan, Christine Wilcox, C. Scott Hardaway Jr.

Reports

City of Chesapeake is situated between the Cities of Norfolk and Portsmouth along several branches of the Elizabeth River (Figure 1). Because the City's shoreline is continually changing, determining where the shoreline was in the past, how far and how fast it is moving, and what factors drive shoreline change will help define where the shoreline will be going in the future. These rates and patterns of shore change along Chesapeake Bay’s estuarine shores will differ through time as winds, waves, tides and currents shape and modify coastlines by eroding, transporting and depositing sediments.

The purpose of this report is …

Evaluating Recruitment Of American Eel, Anguilla Rostrata, In The Potomac River (Spring 2016), Troy D. Tuckey, Mary C. Fabrizio

Reports

American Eel (Anguilla rostrata) is a valuable commercial species along the Atlantic coast of North America from New Brunswick to Florida. Landings from Chesapeake Bay typically represent 60% of the annual United States commercial harvest (ASMFC 2012). American Eel is also important to the recreational fishery as it is often used live as bait for Striped Bass (Morone saxatilis) and Cobia (Rachycentron canadum). In 2012, Chesapeake Bay commercial landings of American Eel (771,536 lbs) were 72% of the U.S. landings (personal communication from the National Marine Fisheries Service, Fisheries Statistics Division). Since the 1980s, harvest along the U.S. Atlantic Coast …


Forest Diversity And Disturbance: Changing Influences And The Future Of Virginia’S Forests, Christine J. Small, James L. Chamberlain Oct 2015

Forest Diversity And Disturbance: Changing Influences And The Future Of Virginia’S Forests, Christine J. Small, James L. Chamberlain

Virginia Journal of Science

The Virginia landscape supports a remarkable diversity of forests, from maritime dune woodlands, swamp forests, and pine savannas of the Atlantic Coastal Plain, to post-agricultural pine-hardwood forests of the Piedmont, to mixed oak, mesophytic, northern hardwood, and high elevation spruce-fir forests across three mountain provinces in western parts of the state. Virginia’s forests also have been profoundly shaped by disturbance. Chestnut blight, hemlock woolly adelgid, emerald ash borer, and other pests have caused declines or functional extirpation of foundation species. Invasive plants like multiflora rose, Oriental bittersweet, and Japanese stiltgrass threaten both disturbed and intact forests. Oaks and other fire-dependent …

Reports

This project is an extension of earlier efforts within the coastal zone of Virginia to build a platform for enhanced Blue and Green Infrastructure planning. This project is motivated by an interest in extending statewide conservation efforts into estuarine systems and recognition that land use decisions on the upland effect water quality and habitat health in the receiving waters. The project in its entirety has been accomplished in distinct parts. Part one develops a Cumulative Resource Assessment to evaluate the distribution of aquatic natural resources within waters of Virginia’s Chesapeake Bay waters, Back Bay of Virginia Beach, Virginia, and the …


Occohannock Creek Shoreline Erosion Assessment And Living Shoreline Options Report, C. Scott Hardaway Jr., Donna A. Milligan, Kevin O'Brien, Christine Wilcox, Shoreline Studies Program, Marcia Berman, Sharon Killeen, Tami Rudnicky, Center For Coastal Resources Management Oct 2008

Occohannock Creek Shoreline Erosion Assessment And Living Shoreline Options Report, C. Scott Hardaway Jr., Donna A. Milligan, Kevin O'Brien, Christine Wilcox, Shoreline Studies Program, Marcia Berman, Sharon Killeen, Tami Rudnicky, Center For Coastal Resources Management

Reports

This study provides information to Occohannock Creek property owners to help them assess their shoreline stability and their options if erosion is a problem. In the past, shoreline erosion control options were typically limited to rip-rap, groins, or bulkheads. These hard structures often destroyed marsh and other habitat and may not have provided the protection desired. Other methods of erosion control now exist that have been used in a variety of conditions and evaluated for their durability and performance. The alternative techniques incorporate vegetation and are referred to as Living Shoreline designs. Conditions on Occohannock Creek make it a very …
