United Kingdom Butterfly Monitoring Scheme: site location data 2022

This dataset provides the details of all sites on which butterflies have been monitored as part of the UK Butterfly Monitoring Scheme (UKBMS). This includes all standard UKBMS transect sites, Wider Countryside Butterfly Survey (WCBS) sites and targeted species survey sites (timed counts, single-species transects, larval web and egg counts). Data includes the location within the UK, the length and number of sections for the butterfly transect on each site and the number of years each transect has been monitored. The location of some sites are sensitive and are excluded from this dataset. Users requiring access to the complete dataset, including sensitive site location data, can submit a request via the UKBMS website. The UKBMS started in 1976 with fewer than 50 sites. Since then the number of sites monitored each year has increased to several thousand. There are new sites each year and a small number where the transect is no longer surveyed. Details of this are provided in the site dataset in the form of the first and last year in which each site was surveyed. The majority of site data is provided by recorders at the time a transect is created. Site data are crucial in order to determine where extra recording effort is required and to investigate where butterfly populations are changing most and thus where conservation should be targeted, including across different habitat types. The UK Butterfly Monitoring Scheme is organized and funded by Butterfly Conservation (BC), the UK Centre for Ecology & Hydrology (UKCEH), the British Trust for Ornithology (BTO), and the Joint Nature Conservation Committee (JNCC). The UKBMS is indebted to all volunteers who contribute data to the scheme. This work was supported by the Natural Environment Research Council award number NE/R016429/1 as part of the UK-SCAPE programme delivering National Capability.

本数据集详尽地记录了英国蝴蝶监测计划（UKBMS）所涉及的监测站点详情。该计划涵盖了所有标准的UKBMS横断面站点、更广阔乡村蝴蝶调查（WCBS）站点以及特定物种调查站点（包括定时计数、单一物种横断面、幼虫网和卵计数）。数据信息包括英国境内的具体位置、每个站点蝴蝶横断面的段落长度及数量，以及每个横断面监测的年数。部分站点的位置信息由于敏感性而被排除在此数据集之外。如需获取包括敏感站点位置信息在内的完整数据集，用户可通过UKBMS网站提交申请。自1976年启动以来，UKBMS的监测站点数量逐年增加，目前已达到数千个。每年都会有新的站点加入，同时也会有一些站点由于不再进行横断面调查而减少。关于站点调查年份的详细信息以站点数据集的形式提供，包括每个站点首次和最后一次被调查的年份。大部分站点数据由创建横断面时的记录者提供。站点数据对于确定额外记录工作所需的地点、探究蝴蝶种群变化最为显著的区域，并据此确定保护目标至关重要，这包括不同生境类型之间的保护。英国蝴蝶监测计划由蝴蝶保护组织（BC）、英国生态与水文中心（UKCEH）、英国鸟类观察信托（BTO）以及联合自然保护委员会（JNCC）组织并资助。UKBMS对向该计划提供数据的所有志愿者表示衷心的感谢。本项工作得到了自然环境研究理事会（NERC）资助，项目编号为NE/R016429/1，作为英国-SCAPE项目的一部分，旨在提供国家能力。
