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

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. The 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.

本数据集涵盖英格兰南部12个农场内栖息的蜜蜂、蝴蝶、食蚜蝇、鸟类及植物的物种组成与个体丰度数据，同时包含授粉服务数据，以及农田花卉的物种与密度数据。该12个农场按区域划分为4组，每组包含3个农场。每组内的所有农场均纳入英国政府入门级管护计划（Entry Level Stewardship scheme）；其中每组各有1个有机农场，另有1个纳入保护等级管护计划（Conservation Grade scheme）。在4个有机农场与4个保护等级管护农场中，各有3个同时参与英国政府高级管护计划（Higher Level Stewardship scheme）。本次调查对每个农场的所有生境类型采集了代表性样本。记录的传粉类群包括蜜蜂、蝴蝶与食蚜蝇：所有调查年份中，蜜蜂与蝴蝶均尽可能鉴定至物种水平；食蚜蝇仅在2012年与2013年完成种群计数，2014年则尽可能将其鉴定至物种水平。传粉者样带调查数据采集于2012、2013及2014年，盆诱捕器（pan traps）采样数据采集于2012年与2013年。传粉者调查数据附带对应生境与气象配套数据。授粉服务数据来源于2013年放置于各农场的加州罂粟（Californian poppy）植物测定株（phytometer）。花卉与鸟类调查数据采集于2013年与2014年。
