The Monitoring of fishes and crustaceans by Province East Flanders in Flanders, Belgium is an sampling event dataset published by the Province East Flanders (Belgium). The data are collected from targeted monitoring on non-navigable watercourses, from 1985 onwards. Earlier collected data was digitized afterwards, newly collected data is digitized immediately. Only non-threatened species are presented in this dataset. The data are published as a standardized Darwin Core Archive and includes for each occurrence record an occurrenceID, date, location, quantification, length, weight where available and scientific name. Also the physico-chemical parameters of the watercourses at that moment are given when available. Issues with the dataset can be reported at

Data Records

The data in this sampling event 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 16,525 records.

2 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.

Event (core)

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.

Project Data

The spread of invasive alien species (IAS) is not hampered by administrative borders. Aquatic IAS, in particular, spread rapidly through the hydrographic network. To effectively control such species requires coordinated management at higher spatial scales. LIFE RIPARIAS (Reaching Integrated and Prompt Action in Response to Invasive Alien Species) aims to achieve such coordination across regional borders in Belgium, supported by open data and open infrastructure for early warning and management reporting. LIFE RIPARIAS aims at improving decision making on IAS management, early warning systems and management reporting tools. To this end, it develops an evidence-based workflow, translating national management objectives into concrete actions in an efficient manner. Ultimately the project aims at increasing the conservation status of aquatic and riparian habitats. More information on LIFE RIPARIAS is available at the project homepage: You can also follow LIFE RIPARIAS on Twitter (@LIFEriparias) and Facebook (LIFE Riparias).

Title Reaching Integrated and Prompt Action in Response to Invasive Alien Species (LIFE RIPARIAS)
Funding LIFE RIPARIAS is co-funded by the three Belgian regions and the European Union in the framework of the LIFE Programme (LIFE19 NAT/BE/000953). It is running from 2021 to 2026.
Study Area Description Dijle, Mark and Zenne river basin of the Scheldt district, Belgium.
Design Description LIFE RIPARIAS focuses on aquatic and riparian plants as well as crayfish species located in the Dijle, Mark and Zenne river basin of the Scheldt district in Belgium. Cumulative observation data collected in 2000-2015, completed by data gathered from field surveillance in 2021-2022, will provide the baseline to design management objectives and define quantitative targets.

Sampling Methods

Targeted monitoring

Study Extent Flanders
Quality Control All inventarisations are performed and controlled by people with sufficient biological knowledge.

Method step description:

  1. The source data for this standardized occurrence dataset is retrieved from a web feature service (WFS)
  2. This data file was uploaded to a github repository (
  3. We developed a RMarkdown ( and SQL ( script to document and perform the transformation of the data to Darwin Core,which includes transforming the data to an event core (, an occurrence extension ( and a measurement or facts extension (
  4. The resulting Darwin Core data files are uploaded to the INBO IPT ( and documented with metadata.
  5. The dataset is published and registered with GBIF.
