DEMNA : Diatoms samples from an ongoing monitoring network on surface waterbodies of Wallonia (since 2005)

Latest version published by Service Public de Wallonie – Département d’Etude du Milieu Naturel et Agricole (SPW – DEMNA) on Nov 8, 2017 Service Public de Wallonie – Département d’Etude du Milieu Naturel et Agricole (SPW – DEMNA)

WARNING: SOME ERRORS WHERE SPOTED WITHIN THE DATASET. USE IS NOT RECOMMENDED BEFORE 2018 UPDATE. This dataset refers to diatoms samplings performed in the frame of the Eu water framework directive. The microscope slides collection is created, implemented and maintened by the Hydrobiology unit at the Department for the Study of the Natural and Agricultural Environment (DEMNA - Public Service of Wallonia).

Phytoplankton samplings are based on an ongoing monitoring network comprising more than 440 surveyed stations distributed among the Wallonia (Southern Belgium), and which started in 2005. Diatoms, with macrophytes ( doi:10.15468/cumtkq ), fishes ( doi:10.15468/jgddny ) and macroinvertebrates ( doi:10.15468/ew00u8 ), is one of the 4 biological indicator groups used to assess the biological quality of surface water masses. In the case of this collection, the monitoring and sampling designs are adapted to the calculation of the IPS (Index of Specific Pollusensibility) that is reported to Europe every year.

The dataset will be updated yearly, after the reporting to Europe and its underlying validation work. We invite you to consult cigale ( geoapps.wallonie.be/CigaleInter/) to access the assessment results, or to adress specific requests to the DEMNA. please notice that this dataset does not replace any official convention on the provision of biological data delivered by the department.
