Description
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)
Data Records
The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 299,176 records.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Method step description:
- Data are collected in the field by specialized trappers, using the predefined sampling protocol.
- Data from 1987-2014 are registered in atlas blocks (5 x 5 km). All data are aggregated in 13 four-weeks' time periods each year and entered in an Excel spreadsheet.
- An R script script is created to transform the original data structure into a single occurrence format with one value per time period per atlas block each year. Only values for atlas blocks with a number for trapped muskrats remained (299K records i.e. 64% of all records).
- In R geographic coordinates and accuracy are added, based on atlas block indexes, and the time periods are to rewritten into an eventDate format with a begin and an end date.
- The output is an DarwinCore occurrence file, which is uploaded via the NLBIF IPT and documented with metadata.
