This European Standard provides guidelines for the survey/sampling; identification and basic quantification of phytobenthos (other than macrophytes) in running waters. It is applicable to rivers where benthic algae and bryophytes are the main phototrophs.This method encompasses all phytobenthic growth forms and enables biological responses to environmental events over one or more years to be monitored. InThis respect it provides an alternative to methods based on benthic diatoms (EN 13946; EN 14407) and macrophytes (EN 14184). Data obtained for the phytobenthos growth forms are suitable for pilot surveys; water quality assessment and trend monitoring.This European Standard encompasses all aspects from the design of survey and sampling programmes to the identification and basic quantification of the phytobenthos.
