Muskrat trapping data in the Netherlands 1987 – 2014

Trapped muskrats in the Netherlands have been manually registered at municipal and provincial level since 1941, from 1987 they have been registered on atlas blocks (5 x 5 km) and from 2014 this is done with a smartphone at the trap location. The years of registration have yielded a valuable dataset that has been used in multiple studies. The trapping data is in multiple GBIF datasets with different accuracies: -> MICA - Muskrat and coypu occurrences collected by UVW in the Netherlands (from 2014), data per trapped animal with exact location and date (https://doi.org/10.15468/qjds4c) -> Muskrat trapping data in the Netherlands 1987 – 2014, data on atlasblock level per period of four weeks (this dataset) -> Muskrat trapping data in the Netherlands 1964 – 1986, data on province level per year (to be delivered) -> Muskrat trapping data in the Netherlands 1941 – 1963, data at municipality level per year (to be delivered) -> Coypu trapping data in the Netherlands 1988 – 2013, data at organization level per year (to be delivered)自1941年起，荷兰便对人工捕获的麝鼠（muskrat）开展市级与省级层面的人工登记工作；1987年起，登记工作转为以5×5公里的地图方块（atlas block）为单位进行；2014年至今，则改为在捕获现场使用智能手机完成登记。历年积累的登记数据形成了极具科研价值的数据集，已被多项研究采用。 该捕获数据分布于多个收录于全球生物多样性信息机构（Global Biodiversity Information Facility，简称GBIF）的数据集，各数据集的精度存在差异，具体如下： 1. MICA项目：荷兰UVW机构收集的2014年至今麝鼠与河狸鼠（coypu）观测记录数据集，包含单只捕获个体的精确位置与捕获日期信息（https://doi.org/10.15468/qjds4c） 2. 荷兰1987–2014年麝鼠捕获数据集：以地图方块为单位、按四周为周期汇总的登记数据（即本数据集） 3. 荷兰1964–1986年麝鼠捕获数据集：按年度汇总的省级层面登记数据（待发布） 4. 荷兰1941–1963年麝鼠捕获数据集：按年度汇总的市级层面登记数据（待发布） 5. 荷兰1988–2013年河狸鼠捕获数据集：按年度汇总的机构层面登记数据（待发布）
