Early warning system on Introduced Species in Wallonia is a presence-only dataset aimed to deliver in real time the occurrence records of introduced species within Wallonia. Data are aggregated from various online recording systems that are maintenaid by the Département d'Étude du Milieu Naturel et Agricole (SPW-DEMNA).
Among these encoding systems, we find OFFH (Observations Faune Flore Habitats), the main occurrence encoding platform for the department experts and partners. But also specific surveys on exotic species (e.g. on the Giant Hogweed) open to the general public and thus based on citizen participation.
As this dataset aims to feed an alert system on exotic species, it also include non-validated data and attention should be paid to the validation status of the records!
If you have any return or remark, please do not hesitate to contact the Department for further details.
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 74,939 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.
The table below shows only published versions of the resource that are publicly accessible.

introduced species from Wallonia. The dataset covers both plant and animal species mentionned as non native by the Global Register of Introduced and Invasive Species - Belgium, and within other shorter listings. As mentionned in the basic metadata, this watch list also includes taxa that should not be considered as invasive for the entire wallonia/Belgium but from which the distribution dynamics are monitored.
|Kingdom||Animalia Linnaeus, 1758 (Animals, Metazoan), Haeckel (1866) (Plants)|
|Living Time Period||1978 to now|
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: https://www.riparias.be/.

|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.|
The personnel involved in the project:
- Principal Investigator
Data are derived from a variety of contexts, including structured or targeted inventories conducted by the Department's experts and partners, their opportunistic observations, as well as citizen science via online survey modules targeting invasives and facilitating their participatory monitoring
|Study Extent||Wallonia, southern Belgium. Data derives from diverse encoding facilities, all managed by the Département d'Etude du Milieu Naturel et Agricole (SPW-DEMNA).|
|Quality Control||Validation of each record is an important part of DEMNA-SPW's data policy. All raw records are submitted to a validation by biodiversity experts of the department. This validation can be based on a photo, on the observer's expertise or on plausibility. However, as this dataset serves as an early warning system, it also contains UNVALIDATED data and special attention must be paid to the identificationVerificationStatus field.|
