Flower-insect timed count data from the UK Pollinator Monitoring Scheme, 2017-2020 version 2

This dataset contains information on the location of the count, some environmental variables, and the number of insects of each type counted for the Flower-Insect Timed Count survey as part 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 duplicate data rows, which have been deduplicated in version 2. The “public” FIT Count asks volunteer citizen scientists to count the number of insects, identified into broad taxon groups, seen landing on the flowers of a particular target plant within a 50 cm × 50 cm quadrat during a period of ten minutes. The “1 km square” FIT Count uses the same methodology, but is carried out by PoMS volunteers and staff as part of the PoMS 1 km square survey, which takes place within a randomly allocated set of 1 km squares in England, Scotland and Wales, and also gathers data on pan-trapped insects (see separate dataset). 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 is jointly funded by Defra, the Welsh and Scottish Governments, JNCC and project partners.

本数据集为英国传粉者监测计划（UK Pollinator Monitoring Scheme, PoMS）下属的花-昆虫计时计数（Flower-Insect Timed Count, FIT Count）调查相关数据，包含计数点位信息、部分环境变量，以及各类被统计昆虫的数量。该数据集涵盖2017至2020年的数据（注：2017年为试点年份，数据量少于后续年份）。本数据集为第2版；此前版本存在部分重复数据行，第2版已完成去重处理。"公开式FIT计数"要求志愿公民科学家在10分钟内，统计50 cm × 50 cm样方内落在特定目标植物花朵上的昆虫数量，并将其归类至宽泛的分类单元组中。"1平方公里样方FIT计数"采用相同的调查方法，但由PoMS志愿者与工作人员作为PoMS 1平方公里样方调查的一部分开展。该调查在英格兰、苏格兰与威尔士随机分配的1平方公里样方范围内进行，同时还会采集盘诱昆虫的相关数据（详见独立数据集）。英国传粉者监测计划由英国生态与水文中心（UK Centre for Ecology & Hydrology）、熊蜂保护信托基金（Bumblebee Conservation Trust）、蝴蝶保护协会（Butterfly Conservation）、英国鸟类学信托基金会（British Trust for Ornithology）、Hymettus、英国自然历史博物馆（Natural History Museum）、雷丁大学（University of Reading）与利兹大学（University of Leeds）联合发起，并与蜜蜂、胡蜂与蚂蚁记录协会（Bees, Wasps and Ants Recording Society）、更广范围的利益相关方以及志愿网络开展合作。PoMS由英国环境、食品与农村事务部（Defra）、威尔士与苏格兰政府、英国自然保护委员会（JNCC）以及项目合作方联合资助。
