Description
. Within the National Surface Water Quality Monitoring Programme (NAWA), water quality is recorded jointly by the federal and cantonal authorities at around 100 monitoring stations. The biological water status is assessed on the basis of macrozoobenthos investigations by the macrozoobenthos module in the Modular Stepwise Procedure (www.modul-stufen-konzept.ch). The outcome of anthropogenic interference in the rivers is generally assumed to be reduced biodiversity, which particularly affects some insects. The small invertebrates on the bed of a watercourse are called macrozoobenthos. A large part of the life cycle of these organisms is spent in the water, which makes them suitable bioindicators because they integrate the water status throughout their life span and because their requirements in terms of water quality and habitat are largely well known
