Sand Lizard

Before the impact of large scale farming, much of England and Wales was covered in heath land between extensive forests. In recent times, however, these heath lands have been decimated.

Today dry lowland heath is the world's rarest habitat, and the tiny areas of it which remain in the UK make up 40% of that total. We are therefore custodians of nearly half of the dry lowland heath left in the world, and its occupants which include one of the world's rarest lizards, (Lacerta agilis) the Sand Lizard.

The sand lizard used to be much more common even fifty years ago than it is now, but it was probably never very widespread within historical times. Very little is known about its history in Britain before the 19th century.

It presumably arrived in Britain some time after the last Ice Age ended about 11,000 years ago. During the freezing conditions of the Ice Age, the sand lizard and other warmth loving species would have been restricted southern Europe.

Only when the ice sheets melted did they make their way northwards into Britain. This must have happened before Britain was separated from the continent by sea level rise, about 8,000 years ago. There is no record of sand lizards from archaeological sites so it is difficult to know anything about its history in Britain.
