Thirteen species of salamanders and nine species of frogs and toads are recorded from the Jim Timmerman Natural Resources Area in South Carolina. Additionally, eight species of salamanders and five species of frogs are listed as potentially occurring within the boundaries of the property. Pseudotriton montanus (Mud Salamander) is considered rare on the property due to the scarcity of suitable habitat and is known only from historical records. Ambystoma maculatum (Spotted Salamander) may utilize non-breeding habitat on the property, but known breeding sites are located off the property near the southern boundary. Desmognathus fuscus (Northern Dusky Salamander) is apparently absent from the property, and perhaps from the entire escarpment and mountain region in South Carolina. Current range maps of D. fuscus, based on historical records, suggest a continuous distribution through this region, but a re-examination of pertinent museum specimens reveals that all records from the escarpment and mountains of South Carolina are based on erroneous identifications. Hemidactylium scutatum is known from only two localities in Pickens County near the southern boundary of the property. It is considered rare and patchily distributed in the upstate. Cryptobranchus alleganiensis is apparently absent from the property as well as the entire upstate. Its purported presence in South Carolina is based on one specimen record from the Lake Tugaloo section of the Savannah drainage system. Rana palustris (Pickerel Frog) is uncommon, and Rana sphenocephala (Southern Leopard Frog) is known only from historical records, and may now be extinct within the property. The reported isolate of Bufo terrestris in Pickens and Greenville counties has not been verified following field surveys. It is hypothesized that the several upstate records are based on anomalous specimens of Bufo americanus. The diverse amphibian fauna of the Jocassee Valley was extirpated when the valley was flooded following completion of the Jocassee Dam in 1972.
