Transect walking is a method for assessing butterfly abundance and involves walking a fixed route, called the transect, through an area at least once a week from 1st April until the end of September and within specific weather conditions.

Sites where transects are carried out in Wiltshire are listed below. If you want to become involved Mike Fuller, Wiltshire County Butterfly Recorder, would be very pleased to hear from you. Contact: fullermike@btinternet.com
