SISélune : update of benthic macroinvertebrate data (spring 2024)

The "Bioindicators" data on benthic macroinvertebrates have been updated with the addition of data from spring 2024.

The benthic macroinvertebrate data for spring 2024 has been updated on the SISélune information system. This data includes the updating of biological indices (especiallly the I2M2) as well as the addition of fauna inventories by campaign and by station.

Benthic macroinvertebrate data on the web mapping portal

Focus on two data sets

The "Macroinvertébrés Benthiques : Indices biologiques (I2M2)" dataset displays the value of the I2M2 index at the various stations. By default, the last campaign is displayed, but it is possible to change this campaign (by clicking on the"V" pictogram below the layer legend). Once you have clicked on a station, you can see the value of the I2M2, the graph showing changes in this index over time at the various stations and the Radar graphs of the indicators in the ODInvertebres diagnostic tool.

The "Macroinvertébrés Benthiques : Abondances MIB" dataset displays the list of fauna and their abundance at the various stations. By default, the last campaign is displayed (it is also possible to change this campaign). After clicking on a station, it is possible to view the taxa identified and their abundance.
