MICA - Muskrat and coypu occurrences collected by UVW in the Netherlands is an occurrence dataset published by the Research Institute of Nature and Forest (INBO) and the Netherlands Biodiversity Information Facility (NLBIF). It is part of the LIFE project MICA, in which innovative techniques are tested for a more efficient control of muskrat and coypu populations, both invasive species. This dataset contains muskrat and coypu counts. Here it is published as a standardized Darwin Core Archive and includes for each occurrence record an occurrenceID, date, location, the number of recorded individuals, status (present/absent) and scientific name. Issues with the dataset can be reported at https://github.com/inbo/mica-occurrences/issues

We have released this dataset to the public domain under a Creative Commons Zero waiver. We would appreciate it if you follow the INBO norms for data use (https://www.inbo.be/en/norms-data-use) when using the data. If you have any questions regarding this dataset, don't hesitate to contact us via the contact information provided in the metadata or via opendata@inbo.be.

The data were collected as part of the MICA project, which received funding from the European Union’s LIFE Environment sub-programme under the grant agreement LIFE18 NAT/NL/001047.

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 566,791 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.


The table below shows only published versions of the resource that are publicly accessible.

Project Data

Invasive alien species such as the coypu and muskrat pose a major threat to biodiversity and cost millions of euros annually. By feeding on rushes and reeds, these animals cause serious damage to the environment in which they live and endangered species suffer from habitat loss. The disappearance of reeds and digging in dikes represents a safety risk for humans in the lowland areas. With the LIFE project MICA (https://lifemica.eu/), the partners from the participating countries want to develop a transnational plan for the management of coypu and muskrat populations in Europe and aim to reduce their population. The objective of an effective population control of coypu and muskrat is to protect lowlands from flooding, to prevent crop damage and loss of biodiversity. The objective of the project is to serve as a pilot and demonstration project in which ‘best practices’ are tested and new techniques are developed for a more efficient control of muskrat and coypu populations. By involving organisations from Belgium, Germany and the Netherlands, the project also promotes international cooperation and knowledge exchange in the field of muskrat and coypu management.

Sampling Methods

No Description available

Method step description:

  1. Data are collected in the field by specialized trappers, using the predefined sampling protocol.
  2. An R script script is created to map the original data to Darwin Core as occurrence Core.
  3. The Darwin Core text file (occurrence.txt) is uploaded in the NLBIF IPT and documented with metadata.
  4. The dataset is published and registered with GBIF.
