niels.schild@vlaanderen.be 2025-05-13 eng The Monitoring of invasive alien crayfishes in the Flemish part of the LIFE RIPARIAS areas is an event dataset published by Agency for nature and forests (Flemish government, Belgium). The data are collected from targeted monitoring on ponds within the nature areas managed by the Agency for nature and forests, in the summer of 2022. Only invasive 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 and scientific name.

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.

niels.schild@vlaanderen.be The source data for this standardized sampling event dataset is an Excel spreadsheet managed by the Agency for Nature and Forests. This data file was uploaded to a github repository (https://github.com/riparias/anb-crayfishes-occurrences/tree/main/data/raw). We developed an RMarkdown (https://github.com/riparias/anb-crayfishes-occurrences/blob/main/src/dwc_mapping.Rmd) and SQL (https://github.com/riparias/anb-crayfishes-occurrences/tree/main/sql) script to document and perform the transformation of the data to Darwin Core, which includes transforming the data to an event core (https://rs.gbif.org/core/dwc_event_2022-02-02.xml) and an occurrence core (https://rs.gbif.org/core/dwc_occurrence_2022-02-02.xml). The resulting Darwin Core data files are uploaded to the INBO IPT and documented with metadata. The dataset is published and registered with GBIF.

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: https://www.riparias.be. You can also follow LIFE RIPARIAS on Twitter (@LIFEriparias) and Facebook (LIFE Riparias). 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. Dijle, Mark and Zenne river basin of the Scheldt district, Belgium. 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. 2022-10-28T19:49:30.373+02:00 dataset Boets P, Pardon N, Reyserhove L, Oldoni D, Schild N (2025).
