Main Development Site

Activity: Ecological work

Four species of reptile are known to be present within the main development site area: adder, slow-worm, grass snake and common lizard. During the planning process for Sizewell C, the project published a strategy for limiting the impact on these species during the construction phase. Broadly, this comprised: preparing and managing sites to receive translocated reptiles; capturing and translocating reptiles in areas of the main site; and monitoring the reptile populations throughout all phases of the project. Five receptor sites – Kenton Hills, St James Covert, Studio Field Complex, Great Mount Walk/ Low 40 Acres, and Aldhurst Farm – have been created in advance of impact, providing a total habitat of around 170 hectares.

A number of techniques will be used to capture the reptiles in the areas needed to build Sizewell C, so that they can be moved safely to one of the receptor sites.
