The Sweco Ecology Calendar

The Sweco Ecology Calendar provides useful guidance for survey and mitigation timings – both optimal and sub-optimal – throughout the year. Our focus is on 10 species – please contact us if you need advice on animals that are not included in this overview.

Professional advice should always be sought when carrying out surveys, and a survey/mitigation licence from the relevant statutory nature conservation organisation may be required, which Sweco can provide.
