Details

These statistics on butterflies in England contribute to a suite of indicators due to be updated later this year the Biodiversity 2020 indicators for England; earlier data availability allows their release ahead of that publication. Two measures of annual butterfly population abundance are presented: the first for butterflies of the wider countryside on farmland; the second for butterflies of the wider countryside in woodland. The measures are multi-species indices compiled by Butterfly Conservation (BC) and the Centre for Ecology and Hydrology (CEH) from data collated through the UK Butterfly Monitoring Scheme (UKBMS) and the Wider Countryside Butterfly Survey (WCBS). The indicators use data from butterfly transect sites on farmland and in woodland from the UKBMS and additional randomly selected farmland plots from the WCBS. Further details of the methods used to compile the indicators and assess change can be found on the UK BMS website. More information about farmland and woodland indicators is available on the England biodiversity indicators homepage.
