United Kingdom Butterfly Monitoring Scheme: site location data 2012

This dataset provides the details of all sites which have been monitored as part of the UK Butterfly Monitoring Scheme (UKBMS). Data includes the location within the UK, the length and width of the line transect on each site, and how long the transect has been monitored. The UKBMS started in 1976 with fewer than 50 sites. The number of sites monitored each year has increased to over a thousand since 2008. There is turnover in sites monitored each year and details of the first and last year in which each site was surveyed are given. The majority of site data is provided by recorders at the time a transect is created. The majority of these recorders are volunteers. The Centre for Ecology & Hydrology (CEH) and Butterfly Conservation (BC) collate the data and the UKBMS is funded by a consortium of organisations led by the Joint Nature Conservation Committee (JNCC).

该数据集提供了作为英国蝴蝶监测计划（UK Butterfly Monitoring Scheme，UKBMS）组成部分的所有监测站点的详细信息。数据涵盖各站点在英国境内的位置、样线（line transect）的长度与宽度，以及样线的监测时长。UKBMS于1976年启动，初始监测站点不足50个。自2008年以来，每年的监测站点数量已增至一千余个。每年的监测站点存在更替，数据集还包含每个站点首次和最后一次调查的年份详情。大部分站点数据由记录员在样线创建时提供。这些记录员中多数为志愿者。生态与水文中心（Centre for Ecology & Hydrology，CEH）及蝴蝶保护组织（Butterfly Conservation，BC）负责整理数据，而UKBMS则由联合自然保护委员会（Joint Nature Conservation Committee，JNCC）牵头的组织联盟资助。
