摘要：Trachemys scripta (slider turtle) and other freshwater turtle species have been traded worldwide as pets, but they are often released by owners in wild or in semi-natural habitats, especially in suburban and urbanized areas. In four artificial lakes and ponds of a Regional Park in the North outskirt of Milan (Italy, Lombardy), we trapped non native turtles using basking-traps and landing nets from April to August 2013.We captured 156 Trachemys scripta, 10 Graptemys pseudogeographica and four Pseudemys sp.; the capture-mark-recapture approach estimated an overall number of 224 individuals (95% C.I. 195-270). There was also a strong indirect support for a probable in situ reproduction, with small juveniles captured and a nest-digging female observed.
