Can anyone tell me if there has been anything published on estimating Viviparous Lizard density or population numbers from Survey and mitigation information from the field? I believe there are estimates for Slowworm numbers per hectare is there any information on Viviparous Lizards?

I have been carrying out lizard translocations over the last two to three years. I have found massive numbers (Adults and Juveniles) from very small sites that are surrounded by residential areas.

Various habitat types have been assessed Grassland (undisturbed) Grazing meadows, and even an old car wreckers yard.

from sites less than a Hectare in area have produced around 700 animals. the Brownfield site produced around 350 Lizards but 700 Slowworms were found along with 35 Grass snakes! (this wasnt one of my sites) the information was supplied to the county recorder in Essex.

regards
