Portrait of Green lizard

The wall lizard and the western green lizard, both from continental Europe, have been introduced to the UK.  Of these two, the wall lizard is by far the most abundant.  Wall lizards are tracked through Surrey Amphibian and Reptile Group's excellent Wall Lizard Project

The wall lizard grows to about 19 cm, but more than half of this length is tail.   The male (above left) has bright green markings on its back. The female (above right) is predominantly brown. Green Lizard - Lacerta bilineata - young adult female

There are more than 30 populations of wall lizards scattered throughout the southern UK.  Their distribution suggests multiple releases of this non-native species rather than natural spread.   Any additional populations should be reported to the Wall Lizard Project

The Western green lizard (right) is a little bigger than the wall lizard.  It is native to Jersey but a non-native population has been established on cliff tops in Bournemouth.
