The Wider Countryside Butterfly Survey is the main scheme for monitoring population changes of the UK's common and widespread butterflies. It is important in both assessing the changing status of widespread butterfly species and in providing an indicator of the health of the wider countryside.
The survey is a partnership project run jointly by Butterfly Conservation, the British Trust for Ornithology (BTO) and the Centre for Ecology and Hydrology (CEH). We now have data from the WCBS, carried out on BBS squares spanning back to the pilot years of 2007 and 2008.
All BBS volunteers can take part in the survey by making extra visits to their square between June and August to count butterflies.
Butterfly Conservation have a new online data entry system for the WCBS. BBS volunteers taking part in the WCBS will need to register on this new system before the 2017 season starts. The old sysrtem is no longer available.
Full guidance on how to register to enter data on this system are now available below:
