Translocating reptiles is an important component of mitigation. Slow worms are a species commonly encountered during development.
European Adder (Vipera berus)

The British Isles are home to six indigenous reptile species. The four species that are widespread and most frequently encountered during development works are common lizard (Lacerta vivipara), slow worm (Anguis fragilis), grass snake (Natrix natrix) and adder (Vipera berus). All four species are protected by law and survey work for these species is often required prior to development. The rarer two species of reptile; sand lizard (Lacerta agilis) and smooth snake (Coronella austriaca) have a far more restricted range and specialist habitat requirements. These species require European Protected species licensing from Natural England.

Survey work for reptiles is seasonally constrained and so it is recommended that surveys are commissioned early on to avoid delays to the development. Mitigation efforts typically involve the erection of barrier fencing to prevent reptiles from entering the development site. Artificial refuges are placed within the site footprint and reptiles can then be captured and translocated to a pre-prepared receptor site. We have experience in both reptile survey and mitigation techniques and are able to give advice on legal requirements, timing of works and options for mitigation. We and our associates are also able to supply and erect barrier fencing cost effectively without the need to employ sub-contractors saving both the client's time and resources.
