Translocate amphibians Amphibian Conservation

A replicated, before-and-after study in 1980–1999 of 19 amphibian translocations to five upland sites near to New York, USA (Cook 2002) found that nine translocations of four species resulted in established populations (spring peeper Pseudacris crucifer, grey tree frog Hyla versicolor, Fowler’s toad Bufo fowleri, redback salamander Plethodon cinereus). Four translocations of four species were likely to have been successful based on persistence of offspring records and one translocation failed. The success of five could not be assessed because of insufficient data. In 1980–1995, nine species of locally caught amphibians of different life stages were translocated to one or more of five sites. Monitoring involved frog call counts, funnel traps, drift-fences with pitfall traps, artificial coverboards and visual searches.
