This concept is a revision of the concept published in 2019 (ICPR technical report no. 259). The adjustments are based on the findings of previous evaluations (see ICPR technical report no. 311) and the revision of environmental quality standards at EU level. The states may apply this revised concept to the biota surveys planned within their territory to ensure that the results remain comparable in future.
The report is only available in German, French and Dutch.
