This study used data from 160 urban sites in England, collected by volunteers taking part in the Wider Countryside Butterfly Survey, in which BTO is a partner. Butterflies were chosen as the species group to investigate because they can be sensitive to small changes in habitat, are commonly seen in urban settings, and can reflect the responses of other insects.
