Freshwater samples in MZNA-INV-FRW: Macroinvertebrate samples from the water quality monitoring network along the Ebro Basin

This dataset gathers information about the macroinvertebrate samples collected on rivers and streams of the Ebro River Basin (NE Iberian Peninsula), the second largest catchment in the Iberian Peninsula. The aim was to use freshwater macroinvertebrates to calculate the biological indices required to evaluate the ecological status of the open water bodies within this basin. This dataset is a part of a monitoring network set up by the Confederaci?n Hidrogr?fica del Ebro (hereinafter CHE). This network was established to fulfill the requirements of the European Water Framework Directive (hereinafter WFD).
