9th Triennial Workshop on the Ecology, Status, and Conservation of Diamondback Terrapins
October 28-30, 2022
Athens, GA

We are excited to announce the 9th DTWG Triennial Workshop and to invite you to join us in Athens, GA for a great weekend talking terrapins, reconnecting with old friends, making new friends, and building the collaborations needed to restore and sustain wild terrapin populations and their coastal habitats.

The DTWG community has grown steadily since the inaugural Workshop at the Savannah River Ecology Laboratory in 1994.  The 1994 Workshop was convened in response to growing concern about declining terrapin populations, with the goals of identifying threats to terrapin populations and producing recommendations for management agencies.  The major findings and recommendations compiled from the 1994 Workshop have served as a springboard for scientific research and conservation actions that continue today. 


While a great deal of progress has been made over the past 25 years, the principal threats to terrapins have not been fully mitigated, additional management strategies must be developed and evaluated, and the adoption and implementation of sound conservation practices are needed. We still have work to do. This 9th Workshop renews our commitment to improve our knowledge of terrapin ecology and management, build new collaborations, and chart future initiatives toward recovering and sustaining wild terrapin populations and the marshes they inhabit. We look forward to a great meeting!

About Athens, GA.

Athens, GA is affectionately known as the "Classic City" and often treated as a much smaller sister city to Austin, TX and Madison, WI. Athens is famous for its music scene and being home to bands such as REM, the B-52s, Drive-by-Truckers, Widespread Panic, Cracker, and many more. It is also home to the University or Georgia, which is the oldest publicly chartered institution of higher education in the U.S. Athens has a great food scene and is home to many [arguably too many] award winning craft breweries including Creature Comforts, Akademia, Southern Brewing Company, Athentic Brewing, and ... of course ... is the home of the legendary Terrapin Beer Co. We look forward to providing you with some swag and an opportunity to share some of our great food and beverages. It will be a priority of our Workshop to use and showcase local businesses during your visit.


Flinchum's Pheonix

The main venue for our Workshop will be Flinchum's Phoenix (650 Phoenix Road, Athens, GA 30605) located in the Whitehall Forest just 4 miles from the University of Georgia campus and downtown Athens. Flinchum's is operated by the Warnell School of Forestry and Natural Resources at the University of Georgia. The venue has a spacious upstairs meeting room for our presentations and social events, an additional downstairs room for the poster presentations, decks and a gazebo perched in the canopy for breaks and casual conversations, and there are trails down to the Middle Oconee river if you need to stretch your legs.


Athens has lots to offer in terms of affordable lodging for the Workshop and we aim to make lodging options as flexible as possible for participants. We deliberate chose a weekend when there is no home football game, which should create many hotel and AirBnB options at affordable rates.

There are blocks of rooms at two hotels, the Hilton Garden Inn or SpringHill Suites, right in downtown Athens. Rooms are being held under the block name "Diamondback Terrapin Working Group".

In addition to these and other hotels in the area, Athens has a rich AirBnB community. If you plan to have your own car, you can find a wide range of options. If you plan on using the shuttles we provide, we recommend that you look for an AirBnB reasonable close to campus or downtown Athens. If you have questions on good locations for an AirBnB, you can contact

To assist participants, we have created an place on your Workshop registration where you indicate whether you would like assistance identifying a roommate or roommates to share a hotel room or AirBnB.

We will provide free shuttles that will run Workshop registrants between Flinchum's Phoenix, downtown Athens, Five-Points, and other in-town areas.


Getting to Athens

Athens is located in northeast Georgia about 1 hour east of north Atlanta. Athens is about a 3 hour drive from Charlotte, NC, 4.5 hours from Charleston, SC, 5.5 hours from Wilmington, NC or Jacksonville, FL, 6 hours  from Mobile, AL, 11.5 hours from Cape May, NJ, 12.5 hours from Jamaica Bay, NY, 15 hours from Corpus Christi, TX, and 16 hours from Cape Cod, MA.

The closest airport with easy shuttle access is Atlanta's Hartsfield-Jackson airport. Hartsfield-Jackson Airport is about a 70 mile drive (1.5 hrs) to Athens.

To get from the airport, there are multiple rental car services or you can arrange a one-way or round trip shuttle. We recommend two shuttle services.


Grizzly Delivery 706.352.3638. Grizzly Delivery is a local shuttle and delivery and minority-owned business owned and operated by Wesley Chenoweth. Wesley is a wonderful person and many UGA faculty use his services when traveling to the airport.

Groome Transportation is a regional shuttle service that offers frequent trips direct from Hartsfield-Jackson Airport to several locations within Athens.

Getting around Athens

As stated previously, we will provide free shuttle vans to transport registrants between Flinchum's Phoenix and areas near downtown Athens. Uber and Lyft are also available in Athens at a typical ride costs about $7.50. Athens Transit and the University of Georgia also offer free buses that run around town and campus and should be accessible to most locations of interest.

Oral and Poster Presentations

A key component of the Workshop is the sharing of information and ideas. We invite individual to share their work (research, management, education, advocacy, regulation, community building, etc...). We have several options for participants: an oral presentation or a poster presentation.


Oral presentations will be either 15 minute (12-13 minute talk with 2-3 minutes for questions) or speed talks (5 minutes with a Q&A for all presenters at the end of the session). We do not know the number of 15 and 5 minute talks. We will make this determination to accommodate as many participants as we can. You can indicate if you are willing to present a 15 minute or 5 minute speed talk.


Posters will be hung at the start of the conference and available for viewing and discussion during the entire workshop. Poster presentations will be part of the social event on Saturday, October 29. IMPORTANT: The format size for posters is a maximum of 4 ft X 4 ft. That's right! Try a poster that is 4 ft tall by 3 feet wide or, be square! Posters larger than 4 ft wide or tall will not be displayed. The poster dimensions are to maximize the number of posters we can accommodate and to encourage people to be creative and efficient with information. Break away from that stale old dense poster format. Have some fun. Here is a link to a Pinterest page with lots of ideas for vertical or square poster formats:

You will select whether you want to present and the types of presentation formats that you will consider as part of your registration. You will also upload your abstract as part of the registration process. You can modify your abstract submission and registration until September 30, 2022.

Abstract Submission

Abstracts for posters or oral presentations must be received by 11:59 PM on Thursday, September 1, 2022. Abstracts must be 300 words or less (excluding the title, author names and affiliations, and key words). A sample Abstract is included below. Please attach abstracts as a Word document to your abstract registration. Please label the file as the last name of the first presenter and then "_2022_DTWG_Abstract". (e.g., Smith_2022_DTWG_Abstract).




TITLE: Effects of Salinity on Hatchling Diamond-Backed Terrapin (Malaclemys terrapin) Growth, Behavior, and Stress Physiology

ABSTRACT: Diamond-backed terrapins inhabit coastal salt marshes along the eastern and Gulf coasts of North America. Terrapins are adapted to intermediate salinities yet frequently face saltwater-inundated marsh habitat exceeding 25 ppt (or grams/kilogram). We investigated the effect of salinity on the growth of hatchling terrapins and on their compensatory responses to salinity stress. We randomly assigned 30 terrapin hatchlings each to one of five salinity treatments (1, 5, 10, 20, or 35 ppt). Over 75 d, we regularly monitored behavior, appetite, and changes in growth; and calculated ratios of heterophils to lymphocytes (H:L ratio) to assess responses to prolonged salinity stress. Consistent with prior studies, chronic exposure to high salinity significantly reduced hatchling growth. Hatchlings in 20-ppt and 35-ppt salinities exhibited appetite suppression and saltwater avoidance and were more likely to show freshwater-seeking behaviors. H:L ratios were higher among hatchlings in 20- and 35-ppt salinities, consistent with a corticosterone-driven stress response to sustained high-salinity exposure, which may play a role in limiting growth. Our findings suggest hatchling growth and distribution among local habitats will vary spatially depending on habitat salinity and freshwater accessibility. The growth-limiting effects of chronically high salinity or limited access to freshwater could therefore increase hatchling mortality and be an important driver of spatial variation in terrapin demography and abundance. However, when freshwater sources are available, compensatory behaviors might reduce growth-limiting effects. Terrapin recruitment is likely to be impacted as rising sea levels, increased human water use, land development, and other anthropogenic changes alter freshwater inputs to coastal marshes. 


KEY WORDS: Climate change; H:L ratio; Salt marsh; Sea level rise
