History:

This colony, based in the grounds of large garden in Bristol's city centre, was discovered by am employee of the BBC Natural History Unit in 2006. The species has been confirmed by photograph and survey. The animals are the green-backed form that is normally associated with North Western Italy.

Gardeners at the site report that lizards have been present for 'some years'. Juveniles with an estimated birth year of 2007 have been observed, suggesting that this is a breeding colony.

Recently, groundskeeping staff have taken an interest in the lizards and are improving the habitat to better suit the animals.

 
Ecological impact:

This city centre park is isolated from most native herpeta, with the exception of the occasional Grass snake, and perhaps Slow worms. The ecological impact of this colony is judged as negligible.

 
Habitat:

Public city-centre recreation park, using rockeries, steps and architectural features.

 
Morphology:

Some animal appear to resemble the Podarcis muralis maculiventris sub-species of northen Italy.
