Reptiles

Reptile populations in the UK have suffered significant declines due to the loss of suitable habitat from increasing development and agricultural pressures. The threats faced by all reptile species are highlighted by their inclusion on Schedule 5 of the Wildlife and Countryside Act 1981 (as amended). This legislation protects against deliberate or reckless killing and injuring and sale. The smooth snake and sand lizard are afforded additional protection under the Conservation of Habitats and Species Regulations 2010, which prohibits damage or destruction to their breeding sites and resting places.

The four more widespread species, comprising slow-worm, common lizard, adder and grass snake, are encountered fairly frequently on development sites and often exploit brownfield habitats which have been left to re-colonise with vegetation.

ECOSA have extensive experience in surveying for reptiles to assess for presence, population status and to identify key areas of habitat. Using our survey data to devise appropriate mitigation strategies, we have successfully implemented mitigation works, which include carrying out numerous large-scale exclusion and translocation projects. Mitigation works include the creation, maintenance and management of reptile habitat.

Reptile surveys are carried out between March and October, with peak survey seasons being April to June and September to October.

Minimum survey requirements for reptiles: seven visits during the months April to September to assess probable absence or presence.  If found to be present, a total of 20 visits would be required for population assessment within that time frame.
