There are six native species of reptiles. The more rare sand lizard and smooth snake are protected by both national and international law. Grass snake, slow worm, common lizard and adder are partially protected under UK law making it an offence to deliberately kill or injure them.
When would I need a reptile survey?
The first stage preliminary ecological appraisal (PEA) would identify if suitable habitat exists on the development site for reptiles. Suitable habitat typically would include rough grassland, hedgerow bases, heathland, brash/log piles and tall ruderal vegetation. If the habitat was going to be impacted on which could result in killing and injury to reptiles, a reptile survey may be recommended.
What is a reptile survey?
The aim of a reptile survey is to establish the presence or likely absence of reptiles on site. This is generally achieved through the installation of a series or artificial refugia (squares of roofing felt or corrugated tin), which are then subject to a minimum of seven inspections in suitable weather conditions. Any natural refugia that may already be present on site, e.g. log piles, will also be inspected where safe to do so.
Reptiles will hibernate over winter so they are generally active between March and October. The optimal survey months tend to be April, May and September. It is possible to survey between June – August, but only in suitable weather conditions.
What happens if reptiles are found?
If surveys confirm reptiles are present on site and it is not possible to avoid impacting on them, it will be necessary to implement appropriate mitigation. The exact mitigation will be project-specific however it could include habitat manipulation (encouraging them to move out of the working area into suitable adjacent habitat) or fencing and translocation for larger projects. If the project involves smooth snakes or sand lizard, a European Protected Species Mitigation licence may be required.
