Reptiles in Scotland are given protection under the Wildlife and Countryside Act (as amended). Reasonable measures need to be taken to avoid the incidental killing or injuring of common lizards, slow-worms, adders and grass snakes in the context of development activities.
Surveys can be carried out in order to establish the presence or absence of reptiles utilising visual observation, walkovers and the use of refugia (tin sheeting or carpet tiles) which they use for shelter. Optimum survey times are the months of April, May and September although reptiles are generally active between March and October.
Any impacts which may destroy suitable habitat where the animals are present or have the potential to kill or injure reptiles during the active period or winter months, when they are hibernating below ground, are likely to require licensing.
