Release reptiles outside of their native range
A replicated study in 2003 on an island containing forest and scrub in the US Virgin Islands (McNair & Mackay 2005) found that releasing St. Croix ground lizards Ameiva polops outside of their native range on to a newly created island resulted in a population that survived and grew over 10 years after release. Ten years after release, 21 individual lizards were identified on the island (9 adults, 11 juveniles and 1 not aged) and the total population size was estimated at 60. Ten lizards were translocated from Protestant Cay in 1990 and one from Green Cay in 1995 to the dredge spoil islet, Ruth Island (7.5 ha, made in 1965 from the construction of a shipping channel), where the species had not been present before. Lizards were visually surveyed five times from March to May 2003 on 20 randomly chosen 25 x 4 m plots in vegetated parts of the island.
