River assessment in Germany
The Federal Environment Agency (Umweltbundesamt) and the Working Group of the Federal States on Water Problems (Länderarbeitsgemeinschaft Wasser) have recently funded several projects, which developed the basis of a new, highly standardised river assessment method for Germany, which fulfils the demands of the WFD.
Products of the projects are:
Field- and lab methods for benthic invertebrate samples
An operational taxa list describing the identification level for future investigations
New identification keys and a compilation of existing keys
New assessment and calculation methods
Software to assess the ecological status of rivers
This website describes the assessment procedure from the selection of a sampling site up to data interpretation.
