Initial assessment methods for 28 European stream types and more generally applicabletoolsforstreambiomonitoringinEuropeweregenerated. The development of the system was based on a newly collected data set covering stream types in Austria, the Czech Republic, Germany, Greece, Italy, The Netherlands, Portugal and Sweden. Altogether, 901 benthic invertebrate samples were taken using a standardised multi-habitat sampling procedure and a large number of parametersdescribing the streamsand theircatchmentswas recordedfor all sampling sites.
