Transect walk data collected in English agroforestry and monoculture fields.

Data on <b>bumblebee</b>, <b>solitary</b> <b>bee</b>, <b>hoverfly</b>, and <b>butterfly</b> observations. Data were collected on standardised transect walks between 2011-2013 at six agroforestry sites in England, in paired agroforestry and monoculture fields. All farmers gave approval for data collection at their sites.Columns A-AA give details of sites, dates of visits, position on transect, and environmental variables.Columns AB-BS give abundance counts for bees, butterflies and hoverflies. Bumblebees and butterflies were recorded at the level of individual species, apart from Bombus terrestris and Bombus lucorum which were recorded as one aggregate species, and Pieris rapae &amp; Pieris brassicae which were also recorded as one aggregate species. Solitary bees and hoverflies were not identified to species.Below are details of column names where their content is not immediately obvious:<i>visit</i> - we sequentially numbered visits to each site.<i>jdate</i> - number of days since 1st March<i>landuse</i> - a, arable; p, pasture<i>treatment</i> - AF, agroforestry; MC, monoculture<i>alleywidth</i> - distance between tree rows, in meters<i>alleylength</i> - the length of tree rows, in meters<i>hedg_dist</i> - the shortest distance between the transect and the nearest hedgerow<i>boundSR_all</i> - plant species richness in field boundaries (both hedges and margins)<i>boundSR_ip</i> - the species richness of insect-pollinated plants in field boundaries (both hedges and margins)<i>bound_area</i> - the area covered by the field boundaries<i>n_hedg_bound</i> - the number of hedged field boundaries<i>n_hedg_trees</i> - the number of trees in field boundaries<i>snh</i> - the percentage of semi-natural habitat (SNH) in a 1 km buffer around field perimeters<i>tran_pos</i> - whether that part of the transect was at the edge or the centre of an alley<i>tran_dist</i> - each transect was separated into 25 meter sections, and this variable specifies the section<i>start_time</i> / <i>end_time</i> - the start and end of the transect. Where it was necessary to stop to catch and identify a bee, the transect walk was paused. This means that transects are not all of equal time length, although time actually spent walking and searching for pollinators was standardised.<i>sun</i> - the percentage of the transect that was sunny (time estimated during transect)<i>wind</i> - how windy it was during the transect, using Beaufort scale values<i>beeact</i> / <i>buttact</i> - a subjective indication of how active bees / butterflies were during the transect ('low', 'medium' or 'high' activity)Columns giving butterfly family names (e.g., Nymphalidae) are row sums of observations of species in that family.
