Pan-trap survey data from the UK Pollinator Monitoring Scheme, 2017-2020 version 2

This dataset contains samples and occurrences of insects and flowers collected for the 1 km square survey of the UK Pollinator Monitoring Scheme (PoMS). It covers the years 2017 to 2020 (note that 2017 was a pilot year and has less data than subsequent years). This is version 2 of the dataset; the previous version contained some incorrect values for the summed totals of counted insect specimens, which have been corrected in this version. This survey uses pan-traps positioned on transects within a randomly allocated set of 1 km squares in England, Scotland and Wales. The sample data contains information on the location of the traps, various environmental variables, and the total number of insect specimens collected. The occurrence data for insects contains records of all hoverflies and bees from the traps, identified (wherever possible) to species level. The occurrence data for flowers contains records of all forbs that are in flower within 2 metres of each pan-tap station. (In addition, Flower-Insect Timed Counts are carried out in the same 1 km squares, see separate dataset for these data.) The UK Pollinator Monitoring Scheme is a partnership between the UK Centre for Ecology & Hydrology, Bumblebee Conservation Trust, Butterfly Conservation, British Trust for Ornithology, Hymettus, Natural History Museum, University of Reading and University of Leeds, working with the Bees, Wasps and Ants Recording Society, wider stakeholders and volunteer networks. PoMS in 2017-2020 has been jointly funded by Defra, the Welsh and Scottish Governments, JNCC and project partners.

本数据集收录了为英国传粉昆虫监测计划（PoMS）1平方公里方格调查所采集的昆虫和花卉样本及其出现情况。该数据集涵盖了2017年至2020年的数据（请注意，2017年为试点年份，数据量少于后续年份）。这是数据集的第二个版本；前一个版本中昆虫样本计数总和存在一些错误值，在本版本中已进行修正。该调查采用在英格兰、苏格兰和威尔士随机分配的1平方公里方格内的样带上的全捕捉陷阱进行。样本数据包含了陷阱位置、各种环境变量以及收集到的昆虫标本总数的信息。昆虫出现数据包含了陷阱中所有飘虫和蜜蜂的记录，尽可能识别到物种水平。花卉出现数据包含了每个全捕捉陷阱站点2米范围内所有开花的杂草的记录。（此外，在相同的1平方公里方格内还进行了花卉-昆虫定时计数，有关这些数据的详细情况请参阅单独的数据集。）英国传粉昆虫监测计划是由英国生态与水文中心、大黄蜂保护信托、蝴蝶保护组织、英国鸟类保护信托、Hymettus、自然历史博物馆、雷丁大学和利兹大学联合发起的一项合作项目，并与蜜蜂、黄蜂和蚂蚁记录协会、更广泛的利益相关者和志愿者网络共同合作。2017-2020年的PoMS项目由英国环境、食品和农村事务部（Defra）、威尔士和苏格兰政府、联合自然保护委员会（JNCC）和项目合作伙伴共同资助。关于本数据集的详细信息可查阅https://doi.org/10.5285/2c43ba3c-d821-442c-989b-754451d72091。
