  1. Create ponds for amphibians

    A before-and-after site comparison study in 1979–1991 of three created ponds in a Carolina bay wetland in South Carolina, USA (Pechmann et al. 2001) found that the permanent created ponds supported a significantly different amphibian community structure compared to the seasonal wetlands they were replacing. Four to 13 frog and toad and two salamander species were recorded in created ponds, with three other salamanders seen rarely. Juveniles of 10 frog and toad and two salamander species metamorphosized and left the ponds. The original wetland had breeding populations of 7–15 frog and toad and 4–5 salamander species. Few frog and toad colonists had been recorded at the original wetland. Mean size at metamorphosis was significantly smaller for two species of frogs and greater for two salamander species at created ponds compared to a reference site. In 1983, three ponds (200 m2, <1 m deep) were created (and lined) on the edge of the original wetland. Amphibians were monitored in the original wetland, created ponds and a reference wetland. Drift-fencing with pitfall traps, minnow traps, dip-netting and seine netting was used.
