Description
"Participatory inventory of the Himalayan balsam within the Dyle basin since 2008" is an occurrence-only dataset serving as an assessment of the invasion on the rivers of the Dyle basin by Impatiens glandulifra .
The majority of the data was collected between 2008 and 2010 in a participative way thanks to all the partners of Contrat Rivière Dyle-Gette (CRDG), the coordination of this large-scale inventory being ensured by the Coordination Unit at CRDG. Other data came of course to complete and specify this first inventory according to the multiple activities of the CRDG partnership and following the new detections made during the operations of management of the invasive alien species set up annually on the whole sub-basin since summer 2010.
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 1,397 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
The data are collected thanks to all the partners of the Dyle-Gette River Contract, the coordination of this large scale inventory being ensured by the Coordination Unit of Contrats Rivières.
| Study Extent | The dataset focuses the Himalayan balsam along rivers banks within Dyle basin, since 2008. Most of the data has been collected during the 2008-2010 period, but few records were added later, until March 2022. Most of recording dates has not been saved, and the time extent of the inventories has been used as a default value. Thus, the dataset should be considered with caution. |

Method step description:
- various activities with partners, under coordination by Contrats Rivières.
- Gathering of the records within a dedicated GIS layer serving as a state of the art regarding to the Himalayan balsam distribution within the bassin.
Additional Metadata
Dates are uncertain, and provided by default. Caution should be paid on this parameter and the dataset should rather be considered as a 'pre 2023' state of the art.
| Purpose | To establish and maintain an assessment of the invasion of Impatiens glandulifera in the rivers and water points of the Dyle watershed. |
|---|---|
| Maintenance Description | The dataset should no evolve in the future, since new data are aggregated in a new system. |
