YnghylchThe sand lizard is one of the UK's rarest reptiles. It favours sandy heathland habitats and sand dunes, and can be spotted basking on bare patches of sand. Sand lizards are confined to a few sites as destruction of their habitat has reduced their range.
Males emerge from hibernation in spring, turning a bright green colour as they get ready to mate. Females lay their eggs in the sand in June and July, and the young hatch one to two months later.
