  1. Translocate adult or juvenile reptiles: Tortoises, terrapins, side-necked & softshell turtles

    A study in 1989–1992 in a freshwater lake in north-west Italy (Gariboldi & Zuffi 1994) found that some translocated European pond turtles Emys orbicularis released initially into a holding pen (with other associated actions) survived at least three years but there was no evidence of breeding in the wild. Twenty-nine of 41 translocated European pond turtles placed initially in a holding pen were observed at least once in the first four months following their release. Three years after release, at least six of 45 turtles were observed near the release site and a further four turtles were regularly seen 4 km away. No breeding activity was recorded. Fourteen turtles dispersed within two days of release and were not seen again. No dead turtles were found. In spring 1989 and spring 1990, forty-five individually marked European pond turtles were released into a temporary holding pen (13 m2 with an artificial pool of 3 m2) next to a freshwater lake (157 m long) in a protected area closed to the public (1989: 41 individuals, 1990: 4 individuals). Most turtles were released from the holding pen after three weeks (two turtles escaped). Turtles were fed at the release site for two weeks to minimise dispersal. Turtles were surveyed in June–September 1989 and periodically in 1990–1992 (no details of survey method are provided). No specific survival information for the 1990 releases is provided.
