Worth noting the Wareham Forest fire area, and the Puddletown Forest are actually two quite different areas some miles apart. Puddletown Forest is an isolated outlier lying to the west of the main block of Dorset Heaths. Its best known as the hilly heathland area directly behind Thomas Hardy's birthplace. Today it is mostly planted with thick conifer forest with two areas of unplanted heathland, which is obviously the lizard release site(s). The extensive area burned by fire near Wareham (which I saw on the day it was happening), did/does hold Sand Lizard too, but I have only ever seen the odd one or two there. Colonies of Sand Lizard in Dorset seem very thinly distributed nowadays. A couple of places I know I see just the same(?) single individual on repeat visits, with no others. These may be isolated non-breeding individuals nowadays.
