This dataset contains the observed abundances of different freshwater macroinvertebrates taxa in French streams and rivers, extracted from the national surveys, with IBGN protocol (sampling_method). Macroinvertebrates are described at the family level (Taxon). It covers 305 survey sites (site_ID), from 1992 to 2017. The sites have been selected to match the 2 following criteria: shortest time-serie is 10 years and the smallest number of sample occasions is 8 (sampling_date).
Coordinates of sampling points are WGS84 decimal degrees (X_coordinate, Y_coordinate).
