The use of passive methods of sampling, such as automated recording systems, traps, and PVC pipes has enabled us to detect difficult-to-observe species with minimal investment of time. Much of the Okefenokee Swamp is extremely difficult to access and future field efforts will include the expanded use of these methods in remote areas of the Refuge.

We thank the rest of the Okefenokee field crew: William J. Barichivich, Kristina Sorensen, Maya Zacharow, Gary L. Hill, Bob Lewis, and C. Kenneth Dodd, Jr., the regional coordinator of Southeast ARMI. We also thank Amy D. Hester for fieldwork and the Refuge personnel for permission to work in the swamp. The frog loggers were built using a design modification developed by William J. Barichivich (firstname.lastname@example.org).
