Description
"Contrats de Rivière IAS surveillance : monitoring of aquatic and riparian invasive alien species in Wallonia, 2023" is a presence/absence dataset focusing on invasive alien aquatic plants and crayfish collected from the field all over Wallonia (Southern Belgium) since spring 2023.
Data are derived from the monitoring of a set of priority ponds and river stretches where observations of IAS were reported in the past to allow site prioritization for management purposes.
Data compilation, cleaning and validation were performed by the Département de l’Etude du Milieu Naturel et Agricole (SPW ARNE / DEMNA).
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 1,838 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.

Sampling Methods
For vascular plants, the entire site is prospected looking for target species listed in the taxonomic scope section, including banks and water bodies. The effort is adapted to the size of the site. Baited live traps are used to sample crayfish and their activity period was restricted to 1-2 consecutive trapping nights.
| Study Extent | Priority ponds and river stretches, Wallonia, Belgium – April 2023 to present. |
