United Kingdom Butterfly Monitoring Scheme: site location data 2011

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 2012

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 2012), 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 2011

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...

United Kingdom Butterfly Monitoring Scheme: site indices data 2017

M.S. Botham, T. Brereton, S. Harris, C. Harrower, I. Middlebrook, Z. Randle & D.B. Roy
Site indices, as a relative measure of the actual population size, for UK butterfly species calculated from data from the UK Butterfly Monitoring Scheme (UKBMS). Site indices are a relative rather than an absolute measure of the size of a population, and have been shown to relate closely to other, more intensive, measures of population size such as mark, release, recapture (MRR) methods. The site index can be thought of as a relative measure of...

Data from: Have Welsh agri-environment schemes delivered for focal species? Results from a comprehensive monitoring programme

Michael A. MacDonald, Ruth Angell, Trevor D. Dines, Stephen Dodd, Karen A. Haysom, Russel Hobson, Ian G. Johnstone, Vaughn Matthews, Anthony J. Morris, Rob Parry, Catharine H. Shellswell, James Skates, George M. Tordoff & Elizabeth M. Wilberforce
1. Agri-environment schemes (AES) have been criticised for being inadequately monitored and for not delivering the expected benefits to nature. Consequently, the Welsh Government funded a comprehensive programme of monitoring of Welsh AES, which took place between 2009 and 2012. The AES assessment focused primarily on Tir Gofal (which translates as “Land in Care”), but also included the Organic Farming Scheme, and monitoring focused on a range of taxa of conservation importance: arable plants, grassland...

Larval mass and survival data for Maniola jurtina under drought stress, UK

M.P. Greenwell, M.S. Botham, M.W. Bruford, J.C. Day, L.C. Evans, M. Gibbs, I. Middlebrook, D.B. Roy, K. Watts & T.H. Oliver
Larval mass and survival data for Meadow Brown butterflies (Maniola jurtina) originating from nine different source populations in the UK and reared under one of two host plant treatment groups (either control or drought stress) in an outdoor insectary at UKCEH under natural environmental conditions. Each individual larva was monitored at three growth check points throughout development: 49 days after hatching (pre-overwintering), 162 days after hatching (post overwintering during larval growth) and 309 days after...

United Kingdom Butterfly Monitoring Scheme: collated indices 2020

M.S. Botham, I. Middlebrook, S. Harris, C. Harrower, M. Lowe & D.B. Roy
Collated indices are a relative measure of butterfly abundance across sites monitored as part of the UK Butterfly Monitoring Scheme. Data from all survey sites (standard UKBMS transects, Wider Countryside Survey transects and targeted species surveys such as timed, larval web and egg counts) are used in the calculation of these indices. The statistics are presented as log10 values. These values are centred round an arbitrary value of 2 as a mean for the time...

Data on where and why species’ range shifts are hampered by unsuitable landscapes: for moth species in Great Britain

Jenny Hodgson, Zoë Randle, Chris Shortall & Tom Oliver
This dataset concerns moth (Lepidoptera) species in Great Britain and was compiled to address the question: Which landscape attributes have caused differential speeds of range expansion since 1985, both between landscapes and between species? More specifically, does the ‘conductance’ measured across a network of habitat help to predict the speed of range expansion? Conductance is a modelled measure of the speed at which a species could colonise a defined ‘target’ from a defined ‘source’ via...
