"ADVANCING REGIONAL LIVING SHORELINE KNOWLEDGE TRANSFER"
ELLA DIPETTO
Abstract
Living shorelines, novel solutions for shoreline protection,
are becoming a popular alternative to traditional shoreline armoring. These
nature-based techniques balance ecological considerations, like oyster
substrate or fish habitat, with social considerations, such as shoreline
erosion. Despite increasing regulatory support for living shorelines, there
remains key gaps in our understanding of the biological, physical, and
societal factors that influence project success. My graduate research at Old
Dominion University addresses the socioecological benefits and challenges of
living shoreline projects. In this presentation, I will provide an overview
of ongoing research relating to habitat benefits and shoreline protection
services that living shorelines provide. I will also highlight a project
supported by Virginia Sea Grant, which aims to integrate local practitioner
knowledge within a regional conservation framework. Recognizing the need for
inclusive and accessible avenues to disseminate lessons learned, this
project will be critical for improving design and implementation of living
shorelines in coastal Virginia and beyond.
Ella is a third year PhD Candidate in Dr. Eric L. Walters’ Avian Ecology lab at ODU, having received her bachelor’s degree in Wildlife Conservation from Virginia Tech in 2018. She then was involved in a variety of projects encompassing avian research, coastal restoration, and environmental education. Her graduate research is focused on nature-based shoreline solutions, particularly along developed coastlines and residential properties. Ella is interested in both ecological and social considerations of living shorelines and works to better understand the valuable ecosystem services that living shorelines provide.
"STAKEHOLDERS FROM MULTIPLE SECTORS VIEWS AND POLICY APPROACHES TO
MARINE DEBRIS REMOVAL:
A QUALITATIVE CASE STUDY OF VIRGINIA'S ELIZABETH RIVER"
ROBIN DUNBAR
Abstract
Marine debris is a wicked problem and there is a call for
action for stakeholders from across multiple sectors to address this issue
in Virginia. Marine debris can have negative impacts on navigation, aquatic
life, recreation, and economies. Research is rapidly growing on ocean
debris, but so far, it is limited regarding river debris. River systems
function as pathways to the sea for the transport of plastic pollution that
can be detrimental due to animal ingestion, entanglement, and
accumulation. Views and policies about marine debris removal are unknown
among stakeholders of Virginia’s Elizabeth River, home to the world’s
largest naval base and a world-class port. The Elizabeth River was
previously identified as one of three most toxic tributaries in the
Chesapeake Bay, and it has the highest sea level rise on the east coast of
the United States (U.S.EPA, 2022b; VIMS, 2022). During flood episodes and
waves generated by ships, macro plastics (> 25mm) can remobilize and travel from the river to the bay and to the ocean. To gain a deep
understanding of the complexity of the Elizabeth River’s marine debris
problem, a qualitative case study was implemented and included in-depth
interviews and a content analysis. This research contributed to the
literature on Narrative Policy Framework (NPF) illustrating the value of
qualitative studies in the policy process and how stakeholders from multiple
sectors use narratives to tell the story of marine debris in the Elizabeth
River. Thirty-one stakeholders from nine sectors participated; the
stakeholders included representatives from the government, public, private,
non-profit, military, resident, academic, volunteer and fisher sectors. This
study answered: 1.) What are the views of stakeholders from multiple sectors
on the marine debris problems at the mouth of the Elizabeth River? 2.) Which
stakeholders are considered in addressing marine debris issues? and 3.) What
is the match between the views of stakeholders’ and policies to address
marine debris?
Robin Dunbar is an Old Dominion University PhD candidate in the Strome College of Business in Public Administration and Policy and is studying environmental policy and watershed management with a focus on marine debris (litter) in industrial ports and rivers. In addition, for 23 years, she has worked for the nonprofit Elizabeth River Project as the Deputy Director of Education and created and led award-winning environmental education programs to inspire youth to help restore one of the most polluted rivers of the Chesapeake Bay. Her education platforms include the water based, 120’ x 32’ Dominion Energy Learning Barge that is powered by the wind and sun, known as America’s Greenest Vessel, and that was designed in partnership with the University of Virginia School of Architects. Her land-based platform includes the 40-acre Paradise Creek Nature Park that includes an ADA-accessible kayak launch, a maritime forest, a River Academy, and a natural playground that she designed. She has managed over 2.7 million dollars in grants and dozens of awards, including from the White House and the National Science Foundation, the 2019 Presidential Award for Science, Mathematics, Engineering, and Mentoring, and she was recognized as a Local Legacy in 2000 during the Bicentennial of the Library of Congress, by the late Congressman N. Sisisky.

"ASSESSING CARBON STORAGE IN THE LOWER CHESAPEAKE BAY SALT MARSHES:
A SEASCAPE ECOLOGY PERSPECTIVE"
ZLATKA REBOLLEDO SÁNCHEZ
Abstract
Carbon estimates in coastal ecosystems often rely on location,
regional, or national averages without considering spatial variability. This
study used seascape ecology to understand carbon storage in salt marshes of
the lower Chesapeake Bay. Our results indicate shape and size as
predictors. Small and medium-sized marsh patches are more susceptible to
edge effects, resulting in less carbon storage because the edges within the
patches contain less. We observed spatial heterogeneity at various spatial
scales, implying differences across sites, between and within patches. Our
study emphasizes the need for a finer spatially explicit approach to
estimating carbon in marshes, improving management and conservation strategies.
