Zusammenfassung:Two seepage bogs in Blackwater River State Forest, Okaloosa County, Florida, were surveyed using funnel traps along drift fences for 165 trapping days from 23 September 1998 to 1 September 1999. Fourteen amphibian and 23 reptile species were trapped, and two additional anuran species were heard calling in bogs. Bogs were used by some species from the surrounding pine uplands and provided ideal habitat for Pine Barrens treefrogs (Hyla andersonii), dwarf salamanders (Eurycea cf. quadridigitata), southern coal skinks (Eumeces anthracinus pluvialis), and several snake species. Most species were apparently more common in the herbaceous than the shrub portions of bogs. The species composition of amphibian and reptile communities differed between bogs and often between shrub and herb portions of the same bog. Much of this difference was probably due to incomplete sampling of the herpetofaunal community, but some of the difference was due to habitat variation. The warmest months, June and August, produced the greatest diversity of species. Stream temperatures in shrub bogs never dropped below 10°C during the sampling period. Herpetofauna inhabiting seepage bogs is primarily threatened by improper fire frequency or timing, alteration of hydrology, and siltation from and impoundment by roads.
