Quality of rivers vis-à-vis the Biological Macrophyte Index (IBMR) in the territory of Breton SAGEs

This map represents the status of the quality stations of the Breton water courses vis-à-vis the macrophyte biological index (IBMR) in 2018. For each of the stations presenting data (all collection devices combined), this index is represented by a quality class (very good, good, medium, poor, bad), in accordance with the requirements of the WFD. The winning table contains the data history from 2007 to 2018. __Origin__ Source of source data: Agence de l'eau Loire-Bretagne (BD OSUR), AFB, export 2019. Data processing carried out by the observatory of the environment in Brittany in 2019. The winning table contains the data history since 2007. Coordinate fields are expressed in WGS84. Matching of the values of the winning table and the quality classes: 1 = Very good condition 2 & #x3D; Good condition 3 = Average State 4 = Poor State 5 & #x3D; Bad state 0 = No data For more information, you can also consult the data visualisation on the website of l'OEB: https://bretagne-environnement.fr/indices-biologiques-qualite-cours-eau-bretons-datavisualisation __Partner organisations__ Observatory of l’' environment in Brittany [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/d8f5238b9e05694971a108292f8c392d2870ab1e)
