Memphis Zoo & Amphibian Foundation: Working Together to Conserve Georgia's Rarest Frog, the Gopher Frog
In 2019, the Memphis Zoo and the Amphibian Foundation began collaborating on a project to further conserve the Gopher Frog, Rana (Lithobates) capito, through a Memphis Zoo Conservation Action Network (CAN) Grant. The grant was aimed at supporting the expansion of both the in situ and ex situ research initiatives developing at the Amphibian Foundation, and we are extremely grateful for the zoo's support in this project.
In situ Goals

In a task team meeting, we identified Alligator Creek Wildlife Management Area (ACWMA) as a survey site for the Amphibian Foundation, given its relative proximity to Atlanta and the records of Gopher Frogs occupying portions of the WMA. The Memphis Zoo CAN Grant not only supported our research at Alligator Creek, but allowed us to initiate a Community Science project — bringing city-folks who are interested in contributing to amphibian conservation to the area to survey for Gopher Frogs. These sampling events consist of larval (tadpole) surveys with dipnets, and upland surveys of adults, which can be detected in Gopher Tortoise burrows using a Burrow Camera. All of the equipment needed for these surveys were provided by the CAN grant. Through the AF mailing list and social media posts, we recruited people interested in joining us for our field surveys.

Our task is to confirm the presence of Gopher Frog on the WMA, and identify breeding populations.

Ex situ Goals
Back at the Amphibian Foundation, we are focused on two population augmentation programs to bolster wild populations of imperiled Gopher Frogs. The first one is a head-start program (AKA assisted metamorphosis). Head-start in this instance means that eggs are collected from the wild and reared through metamorphosis — then released as small froglets— either right back where they came from or translocated to a recipient pond. The second initiative is to establish captive breeding populations of Gopher Frogs, where we will produce eggs at the Foundation that can be translocated in egg, larvae, or froglet stage into recipient wetlands at Georgia Department of Natural Resource's discretion.
