The scheme has monitored changes in the abundance of butterflies throughout the United Kingdom since 1976. Since then, recorders have made around a quarter of a million weekly visits to more than 1,500 separate sites, walking over half a million kilometres and counting over 16.4 million butterflies! The UKBMS is based on a well-established and enjoyable recording method and has produced important insights into almost all aspects of butterfly ecology.
