United Kingdom Butterfly Monitoring Scheme: site location data 2013

M. Botham, D. Roy, T. Brereton, I. Middlebrook & Z. Randle
This dataset provides the details of all sites which have been monitored as part of the UK Butterfly Monitoring Scheme (UKBMS). Data includes the location within the UK, the length and width of the line transect on each site, and how long the transect has been monitored. The UKBMS started in 1976 with fewer than 50 sites. The number of sites monitored each year has increased to over a thousand since 2008. There is turnover...

United Kingdom Butterfly Monitoring Scheme: species trends 2013

M. Botham, D. Roy, T. Brereton, I. Middlebrook & Z. Randle
This dataset provides linear trends, over varying time periods, for the UK Butterfly Monitoring Scheme (UKBMS) Collated Indices of individual butterfly species across the UK. The main statistical values derived from a linear regression (slope, standard error, P-value) are presented for the entire time series for each species (1976 to 2013), for the last 20 years, and for the last decade. In addition a trend class, based on slope direction and its significance, and a...

United Kingdom Butterfly Monitoring Scheme: collated indices 2013

M. Botham, D. Roy, T. Brereton, I. Middlebrook & Z. Randle
Collated indices are a relative measure of butterfly abundance across monitored sites in the UK, calculated from data collected by the UK Butterfly Monitoring Scheme (UKBMS). Collated indices are calculated annually for each individual butterfly species that has been recorded on five or more sites in that year. Based on this criterion collated indices have been calculated for the entire UKBMS time series from 1976 to the current year for the majority of species. For...
