Delivering biodiversity and pollination services on farmland: a comparison of three wildlife-friendly farming schemes

摘要

Data on the species and abundances of bees, butterflies, hoverflies, birds and plants found on farms together with data on the pollination services and species and densities of flowers, from twelve farms in the south of England. Triplets of farms were selected from four regions. All farms in each triplet were in the Government's Entry Level Stewardship scheme, one from each triplet was organic and one from each triplet was in the Conservation Grade scheme. For the four organic and four Conservation Grade farms, three were also in the Government’s Higher Level Stewardship scheme. A representative sample of all habitats on each farm was surveyed.ududThe pollinator groups recorded were bees, butterflies and hoverflies. Bees and butterflies were recorded to species level as far as possible in all years and hoverflies were counted in 2012 and 2013 and recorded to species level as far as possible in 2014. Data from pollinator transects are from 2012, 2013 and 2014 and data from pan traps are from 2012 and 2013. The pollinator survey data have associated habitat and weather data. Pollination service data are from Californian poppy phytometer plants placed on farms in 2013. Flower and bird data are from 2013 and 2014.
