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

    A study in 1990 in shrubland on Curieuse Island, Seychelles (Hambler 1994) found that a population of translocated Aldabra giant tortoises Aldabrachelys gigantea was still present on the island 12 years after translocation attempts began. A total of 117 tortoises (73 adult males, 38 adult females and 6 juveniles) were found (0.4 tortoises/ha overall; 2 tortoises/ha in occupied areas) 12 years after the start of translocations. Thirteen nesting sites and 21 clutches of eggs were also found. At least five dismembered shells were discovered, and 9% of adults had peeling and flaking shells. Around 250 tortoises were translocation to Curieuse Island between 1978–1982 (95 in 1978; 78 in 1980; around 80 in 1982). In July–October 1990, exhaustive surveys were conducted across the whole of the island and tortoises numbered with paint.
