Translocate frogs Amphibian Conservation

A study in 2000 at Guadalupe Dunes, California, USA (Rathbun & Schneider 2001) found that eight of 11 translocated California red-legged frogs Rana aurora daytonii returned to the original pond within a few days. All seven adults left the release ponds between 24–48 hours after release. Six returned to the original pond in 1–9 days; one was found dead there. The five surviving were translocated again and four remained at the release pond for at least 10–17 days. The fifth adult was found back at the original pond within 32 days having travelled 3 km. Two juvenile frogs also returned to the original pond a number of times; the other two were not recaptured. In February 2000, seven adult and four juvenile frogs were marked and translocated 2 km, from a polluted pond to three natural ponds. The original pond was pumped dry at the end of February. Frogs were monitored by radio-tracking for a month.
