  1. Relocate nests/eggs for artificial incubation: Lizards

    A study in 1979 in the USA (Trautwein 1983) found that a wild-caught northern fence lizard Sceloporus undulatus hyacinthinus laid eggs that hatched successfully following artificial incubation in captivity. Two weeks after being brought into captivity, a female produced a clutch of 17 eggs. Sixteen of 17 eggs hatched successfully after an incubation period of 45 days. In 1979, a female lizard was captured and housed in a plywood box (3 x 4 x 1 feet) with 11 other northern fence lizards of varying sizes and sexes. The enclosures contained rocks and sand and temperatures ranged from 20–46°C. Eggs were moved to a plastic container with holes drilled in the bottom edge and placed in wet vermiculite. Incubation temperatures were 33–34°C for 20 days, and then varied between 20–29°C for the remainder of the incubation period.
