Protected Species surveys are best undertaken at certain times of the year. These times vary according to the species concerned and the type of survey required.

We have produced this protected species and habitats ecology survey calendar as a guide to when the different surveys can be undertaken. This can vary slightly according to when the different seasons occur and therefore when animals come in and out of hibernation or lifecycle stage.

The Thomson Mitigation calendar highlights the best time to undertake mitigation for protected species.

Most protected habitats and protected species need a licence from Natural England for ecological mitigation works. It is important that you check your legal requirements before undertaking any ecological mitigation.
