"Contrat de Rivière - RIPARIAS: detection and management of aquatic invasive alien species" is a presence/absence dataset focusing on freshwater invasive alien species in the Senne basin, since spring 2021.

data are derived from the monitoring of a set of managed or surveilled water points (ponds, rivers) where the progress/elimination of a set of invasive species is followed up.

The dataset includes absence records and should be considered with caution. Each event corresponds to a complete survey of the site in search of a set of targeted IAS.

The dataset also include had hoc presence observations of other introduced or native species that are made on site.

Data Records

The data in this sampling event 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 1,276 records.

1 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.

Taxonomic Coverage

The monitoring mostly targets a specific list of freshwater invasive alien species (detailed below). Absence records are only available for these target species (as their search is part of the protocol). However, had hoc observations of other aquatic species - introduced or native - are also included in the dataset.

Project Data

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.

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.

Sampling Methods

During the visits, the entire site is prospected looking for a set of target IAS. The effort is adapted to the size of the site. For the search of invasive crayfish, traps are also set.

Study Extent freshwater managed or surveilled sites(ponds rivers) within the Senne river basin, from spring 2021 to present.

Method step description:

  1. Site prospection by officers in the RIPARIAS framework
  2. Enconding observations using Fulcrum
  3. Export and generate Darwin Core files for GBIF
