It contains management actions on invasive and nuisance species, with a primary focus on muskrat. Data are collected with the Ecosystem2 app. Here it is published as a standardized Darwin Core Archive.

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 Flanders Environment Agency (VMM) is responsible for controlling muskrats on all streams under Flemish regional jurisdiction. They are complemented by other management actors, such as provincial and municipal trappers, and Rattenbestrijding Oost-Vlaanderen (RATO vzw) and Polders. monthly Piet De Rycke Province West Flanders

piet.derycke@west-vlaanderen.be Field managers record daily operations in a dedicated app. A script periodically retrieves app data via WFS (see https://github.com/riparias/wfl-occurrences/blob/main/src/get_data.R). Data are filtered for confirmed observations/catches of species of interest. This excludes operations where the presence of an animal/plant is uncertain (e.g. extra trap placed, beaver dam observed, etc.). Data are transformed to Darwin Core (see https://github.com/riparias/wfl-occurrences/blob/main/src/dwc_mapping.R) and pushed to GitHub. The INBO IPT is set to auto-publication and periodically retrieves the Darwin Core data from GitHub. The dataset is (re)published to 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. 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. 2026-04-17T09:00:33.043+00:00 dataset De Rycke P, Lejeune K, Reyserhove L, Huybrechts P, Desmet P (2026).
