The future of our butterfly and moth populations in Britain is under threat with many specialist species in serious decline. Butterfly Conservation's reason for being is to save these populations by identifying the causes for the decline and carrying out corrective measures to halt and reverse the trend.

To do this successfully we need volunteer help locally in Wiltshire, particularly from those who may not yet members of BC, to record what is out there by conducting butterfly transects and moth trapping. We have to know what species we have and how they are prospering if we are to save them. Help with scrub clearance on important sites is also a vital role for volunteers.

In parallel, we need to educate the community and in particular the younger generation about moths and butterflies by way of public events such as the annual Bird & Butterfly Day at Iford Manor near Bradford on Avon.
