Brown Bag Lecture Series

The GA Coastal Management Program is pleased to offer the Brownbag Lecture Series to provide professional development opportunities and information sharing amongst coastal management professionals.  The intent is to highlight the work of resource managers, researchers, and practitioners focusing on natural and cultural coastal resources. 

Please see below for upcoming events.  Unless otherwise noted the Brownbags will be held at the GA DNR Coastal Regional Headquarters at One Conservation Way, Brunswick, GA 31520 in the Susan Shipman Environmental Learning Center.  

If you are interested in presenting at a Brownbag please contact Kelly Hill at Kelly.Hill@dnr.ga.gov or 912-264-7218.

And as always, feel free to bring your lunch and a friend!

 


August 26th, 2022| 12pm-1pm| Boat Stories: Leveraging Cultural Heritage to Support Sustainable Coastal Communities| Dr. Jennifer Sweeney Tookes and Mr. Bryan Fluech

This collaborative research project focus on the cultural significance of commercial fishing boats to coastal communities. Tookes and Fluech trained student researchers to conduct oral history interviews with commercial fishers across Georgia to gather important data while providing scientific research training to students.  The project identified local perspectives on planning and development regarding vessels, and suggestions for supporting future resilience of the industry. By focusing on these key entities around which commercial fishers’ lives and businesses have revolved, we are preserving local heritage while simultaneously elucidating realistic approaches for sustaining the industry through future planning and development.  The results of this research are available to the general public and managers through wide-ranging outreach via the national NOAA oral history archive (https://voices.nmfs.noaa.gov/collection/boat-stories) and a Story Map (https://storymaps.arcgis.com/stories/021bc8965b784bd9832e6d88cc7faae0)

July 29th, 2022| 12pm-1pm| Quantifying oyster reef development and nekton use of habitat restored using traditional and alternative substrates in the Skidaway River| Cameron Atkinson, Savannah State University

The eastern oyster (Crassostrea virginica) is an important ecosystem engineer which has experienced declines throughout most of its range. Efforts to restore oyster reefs in Georgia have increased in popularity over the past few decades but there have been some challenges with constructing successful reef complexes. The success of the traditionally utilized restoration substrate, bagged oyster shell, has been hindered by the high sedimentation environment of Georgia’s estuaries and the diminishing availability of relic oyster shell. There is a need for alternative restoration substrates to be tested alongside the bagged shell substrate. Therefore, our research group is currently investigating the use of a novel restoration substrate, Oyster Catcher. The Oyster Catcher substrate consists of jute fibers which are coated in cement and molded into various designs. In May 2021, we constructed 6, 2 m X 10 m reefs (3 Bagged Shell & 3 Oyster Catcher) in the Skidaway River along the shoreline of the Skidaway Island State Park. Our group has been working to quantify the oyster reef development and the provisioning of nekton habitat at these restored reef sites with the aim of developing a better understanding of which substrate type could be the most beneficial for future restoration projects in Georgia.

April 20th, 2022| 12pm-1pm| A Virtual Tour of Gray's Reef National Marine Sanctuary| Superintendent Stan Rogers & Research Ecologist Kim Roberson

This presentation will provide a virtual tour of Gray’s Reef National Marine Sanctuary (GRNMS) including an overview of ongoing and new sanctuary programs and initiatives. To understand how the programs and initiatives support the management goals of the sanctuary, sanctuary representatives will start at the beginning of why GRNMS was designated in 1981, discuss major milestones over the years, and then provide the latest on resource protection, scientific research and monitoring, and education and outreach initiatives including upcoming condition report update and management plan review.

 

GRNMS, off the coast of Georgia, contains one of the largest nearshore, live-bottom reefs of the southeastern United States. Located 19 miles offshore from Sapelo Island, GRNMS is currently the only protected natural reef on the continental shelf off the Georgia coast and one of only a few marine protected areas in the ocean between Cape Hatteras, North Carolina and Cape Canaveral, Florida.

NOAA designated the sanctuary in 1981 to protect the quality of this unique and fragile ecological community. The approximately 22-square-mile sanctuary is just a small part of U.S. territorial waters, yet its value as a natural marine habitat is recognized nationally and internationally.

March 29th, 2022| 12pm-1pm| Evaluating Best Practices in Dune Restoration| Shannon Matzke, GA State Sea Grant Fellow/GADNR Coastal Resources Division 

Coastal communities are developing rapidly in the face of increased risks of sea level rise and hurricanes stemming from anthropogenic climate change. In the US, erosion is projected to cost $530 million/year in property loss, but beaches and dune systems can minimize these losses. Dunes are vital to coastal protection, particularly when they are colonized by native plant species that stabilize sand with their root systems and accumulate sand by trapping particles with their stems and leaves. Dune construction can be used as a nature-based solution to climate change, but more studies are needed to fully understand the best practices that should be associated with vegetating constructed dunes.

To gain more insight into dune restoration, a Coastal Incentive Grant funded team from Georgia Southern and Tybee Island conducted a 15 month study on Tybee Island, GA, the site of new dune construction. They examined the effects of planting density on plant survival and growth and on sand accretion, and they compared accretion rates to those on pre-existing dunes on Tybee and unvegetated sites on the constructed dune.

While specific restoration strategies must be viewed through the lens of management goals, the team’s findings are consistent with the literature and have proven to work well on Tybee Island. The results of this study provide a framework both to future restoration projects on Tybee and to those taking place in other coastal communities.

February 28th, 2022| 12pm-1pm| The Georgia Flood Literacy Project | Meghan Angelina, GADNR Coastal Resources Division Wetlands Biologist

Terms related to flood hazards are being used inconsistently and interchangeably among professionals and the public. This presentation will review the Georgia Flood Literacy Project, an effort to unite 30 professionals from various sectors of the field to see what flood terms are being used and how they are being used.

One of the major goals of this group, known as the Flood Literacy Taskforce, was to work toward clear, consistent, widely applicable, and scientifically accurate definitions of flood terminology. These terms were compiled into professional and public versions of a Glossary of Flood Terms and an ArcGIS StoryMap was created to highlight the project and serve as a resource for flood terms.
