DEMNA : MacroInvertebrate occurrences in monitored surface water bodies of Wallonia

WARNING: SOME ERRORS WHERE SPOTED WITHIN THE DATASET. USE IS NOT RECOMMENDED BEFORE 2018 UPDATE. "DEMNA : MacroInvertebrate occurrences in monitored surface water bodies of Wallonia" is an occurrence dataset created by the Hydrobiology unit at the Department of Study of the Natural and Agricultural Environment (DEMNA- Public Service of Wallonia). The data come from an ongoing monitoring network on the biological quality of water bodies in Wallonia set up to undertake the Eu Water framework directive missions (since 2005). MacroInvertebrates are one of the 4 indicator groups used to assess the biological quality of water bodies with macrophytes(doi:10.15468/cumtkq), diatoms(doi:10.15468/vvkk9a) and fishes(doi:10.15468/jgddny). The occurrences are derived from standardized IBGN/IBGA samplings, and are completed with had hoc observations from non-specific monitorings. Some IBGN/IBGA target taxa have been removed from the dataset, due to the low taxonomic resolution used (classes, orders). The Current monitoring network is composed of more than 440 sites, distributed among small streams to the largest rivers/canals from the hydrographic districts of the Meuse, the Scheldt, the Rhine and the Seine (Wallonia areas). Some data can be previous to the set up of the current monitoring network, collected during other activies of the hydrobiology unit. The results of the Biological quality assessment can be acessed through cigale ( information is available upon request adressed to the DEMNA, and please note that this dataset does not replace any official convention on the provision of biological data delivered by the department. Maintenance of the dataset will be realised each year in order to include previous-year reported samlings.
