|Congratulations to the Summer 2019 class of Master Herpetologists! Here we are at Sweetwater Creek State Park for our 'reptile' field trip (we found amphibians too).

Another semester of the Master Herpetologist program just came to a close, and we certified a group of talented Master Herpetologists. This course has been an exceptional experience for me, and a lot of fun — a great way to get to know other critter enthusiasts and advocates in the area. This semester, we also we lucky enough to have esteemed guest lecturers like John Jensen from GA DNR (now retired) introducing the course, giving a background of the reptiles and amphibians of Georgia, as well as state policies and regulations, Grover Brown from the University of Southern Mississippi talking about — turtles, of course, and Dr. Chris Jenkins of the Orianne Society lecturing about snakes. We are honored to have such authorities come and share their experience and knowledge with our students.

With the support of our partners at the Amphibian and Reptile Conservancy, we were able to make another trip this season to Fort Stewart, GA to search for the endangered Frosted Flatwoods Salamander (Ambystoma cingulatum). Other partners on the project are the US Army, GA DNR and USFWS.
If you didn't see our post a few weeks ago, Fort Stewart has the last known population of Atlantic clade Frosted Flatwoods Salamanders on the planet. (click here to see 'Part 1' of the story). We have been working with Fort Stewart Biologists Larry Carlile, Tim Beaty and Roy King on identifying where on the base these salamanders are still present, as well as collecting a portion of the larvae for the establishment of the world's only captive propagation colony for the species.
This time, we were also assisted by students from my Biology of Amphibians class at Agnes Scott, as well as dedicated Ft Stewart staff and USFWS.

We were eager to sample wetlands we hadn't been to yet this season, but we also wanted to check the water levels at the pond where we detected larvae weeks before — and lucky we did! The occupied wetland had dried to just a few inches of water in some parts, and the larvae were in risk of desiccating before they could metamorphose. That changes the parameters of our study from collection to rescue/salvage.

|We detected another 20 larvae in the pond where we had found 21 just a couple of weeks earlier.|

We returned to the same area of the pond were we had detections on the prior visit and found another 20 larvae for inclusion in our captive propagation program back in Atlanta at the Amphibian Foundation.

|Chris Peterson and Paul Block from the US Navy team of Biologists assisted with the sampling as well. Here Chris is showing off a Frosty he dipnetted in the Alpha 10 Pond.|
|Tom 'Hambone' Hamlin, a Fort Stewart Biologist who has worked on the base for many years, is showing of the first Flatwoods Salamander he has ever detected.|
Next steps: In the upcoming week we will be building an indoor rainchamber/mesocosm for the Frosted Flatwoods Salamanders we collected at Fort Stewart. This will be an indoor rearing and breeding enclosure complete with an upland, wetland, and ecotone mimicking the natural habitat of the Coastal Plain. The hydroperiod and photoperiod (as well as other climatic parameters) will be fully controllable to endure healthy growth and optimal breeding conditions when the salamanders are ready in 2-3 years.

This indoor system was made possible by the generous donations from Zilla and the Joyce Tillman Trust.
