    dct:description """Freshwater diatoms (phytobenthos) are free-living microscopic plants that form a biofilm on submerged substrates such as rock/stone or large plants. They are used as an indicator of water quality because their silica shells are easy to identify under the microscope. This dataset is made up of the relative abundance of different species within the sample from freshwater diatom surveys conducted across Wales by Natural Resources Wales and former Environment Agency Wales. These surveys are conducted as part of on-going monitoring of river water quality for legislative requirements and to meet business drivers.

A geospatial version of this dataset is available to download from DataMapWales.
Please see metadata NRW_DS125742 for more information.""" ;
