Log piles
As well as providing cover from adverse weather, dead wood attracts insects on which amphibians and reptiles will feed. Leave piles of logs around your garden to also provide basking spots for common lizards. Allow vegetation to grow around and through the log pile to provide more shelter and to increase the variety of insects attracted to it.
Rockeries
South-facing rockeries might attract reptiles such as common lizards into gardens, if they are in the area. As well as being a warm place to bask, the nooks and crannies mean they can quickly escape if disturbed. If you have recently dug a pond, use the excavated soil to create a sunny bank and then build rocks and stones into and around it.
