Reptile Survey Haverfordwest

There are four widespread species of British reptile, comprising grass snake, slow-worm, adder and common lizard, and these are given so-called ‘partial protection’ under UK law – it is an offence to deliberately kill or injure them. All of them are commonly encountered on development sites.

Reptile surveys combine two techniques: a visual search and the use of artificial refugia. Surveys are conducted between April and September when animals are active and unlikely to be hibernating.

Reptile mitigation is also seasonally constrained to the period from April to September, and generally involves the erection of reptile-proof fencing and the use of artificial refugia. Substantial effort is required to capture and transfer animals off-site to pre-prepared receptor sites. Protected Species Licences are required if development proposals will affect the two scarcer species: smooth snake and sand lizard, although these are only rarely found on development sites.

Do you require a reptile survey?

We are well placed to help you through the planning process in a cost-efficient and timely manner. Our ecologists have extensive experience in surveying and designing mitigation for reptiles and can advise you on survey methodology, legal protection, mitigation options and the timing of development works. We’re able to provide our services across Pembrokeshire, including areas such as Haverfordwest, Milford Haven, Pembroke, Pembroke Dock and Tenby. In addition to Pembrokeshire, we can also cover the neighbouring counties of Carmarthenshire and Ceredigion.
