The macroinvertebrates are sampled according to the French method IBGN ( indice biologique global normalisé , agences de l' eau 2000). The results allow to classify the surface water bodies into 5 classes : high - good - moderate - poor - bad. Macroinvertebrates are sensitive to the hydromorphology, organic pollution , biological continuity , water regime and acidification. The Macroinvertebrates are one out of four biological parameters of the ecological status of surface water.
