The Wider Countryside Butterfly Survey is intended to complement, not replace transects, and enables records from a wide variety of habitats to be collected. Some squares will be rich in butterflies, others less so, but all results are important. Taking part involves doing two 1km walks on two days in July and August. In order to do the walks the survey route must be planned, and access permission must be obtained. For more information about this, see the WCBS guidance document produced by the UKBMS.

If you would like to volunteer to survey one of the vacant squares, or get more information, please contact the WCBS Co-ordinator at wcbs-coordinator@upperthames-butterflies.upperthames-butterflies.org.uk
