Description
Muskrat captures in Flanders, Belgium is an occurrence dataset published by the Research Institute for Nature and Forest (INBO). It contains information on all officially registered captures of muskrat (Ondatra zibethicus) in and around Flanders, Belgium between 1991 and 2018. These data are provided by different management actors: the Flanders Environment Agency (VMM), Rattenbestrijding Oost-Vlaanderen (RATO vzw), Polders and Wateringen (vvpw), and provincial and municipal trappers, and aggregated and analyzed by the INBO since 1991. more

Here it is published as a standardized Darwin Core Archive and includes for each occurrence record an occurrenceID, date, location, samplingProtocol (trap) and samplingEffort (number of days or traps), scientific name, and the organization who made the capture. The original dataset contains close to 450.000 occurrences and is available on GitHub, but only presence records (over 103.000) are included in this version, which can be used to track muskrat distribution in Flanders since 1991. Issues with the dataset can be reported at https://github.com/inbo/mica-occurrences/issues

This dataset was published for the MICA project, which received funding from the European Union’s LIFE Environment sub-programme under the grant agreement LIFE18 NAT/NL/001047.
This dataset contains officially registered captures of muskrat (Ondatra zibethicus) in Flanders and around. Muskrat is listed as an invasive species of EU concern sensu the EU Regulation 1143/2014, which requires member states to prevent or manage its introduction and spread.
Before 2000, baits infused with rodenticides were used to control muskrats. These catches were seldom registered as animals could not be recovered. It is therefore likely that reported catches up until this point in time are an underestimation. Since 2000, Flanders has banned the use of rodenticides for muskrat control and the control is performed purely mechanical using various types of traps. These traps will be laid out either at fixed distances close to the regional borders as a passive control mechanism or they will be placed where traces of muskrat presence are reported as active control mechanisms (Verbeylen et al. 2002). These traps are controlled minimally each week but at high densities it is more likely that a trapper will check them each day. The date of an observation is therefore the date that the animal was retrieved from the trap. Trapping techniques used in Flanders are described in the best practice of Stuyck (2016).
