Water quality - Guidance on pro-rata multi-habitat sampling of benthic macroinvertebrates from rivers and streams

Edition date: 2026-04-22
In Force
Available languages: German, English
Summary: This document gives guidance for pro-rata multi-habitat sampling of benthic macroinvertebrates in rivers and streams. The term "pro-rata" reflects the intention to sample all the main riverine habitats present at a monitoring site according to the proportion of the site that it covers. It is an objective way to divide sampling effort among the different habitats. This document is applicable to all flowing waters, both artificial, modified and natural. It enables comparable samples to be collected from any type of river, regardless of the habitats present. This document gives guidance on an overall approach rather than a specific method. This document is applicable to: - supporting environmental and conservation agencies, water boards, and water agencies to meet the monitoring requirements of the WFD (Article 8, Annex II, and Annex V) [1]; - generating data sets appropriate for monitoring and reporting of sites designated under the Habitats Directive and the Birds Directive to ensure that samples for comparing the overall composition of invertebrates from different stream types are comparable; - ensuring samples for environmental quality assessments across different stream types are comparable even when sampled by different people; - supporting river management and restoration initiatives; - sampling sites in a consistent way that is not dependent on the presence of particular types of habitat; a user-friendly strategy for collecting biological data depending on the distribution of habitats; - understanding the distribution of biological community types across different physical river types; and - assessing quality based on deviation from reference, as adopted in the European Water Framework Directive [1].

Le présent document fournit des recommandations relatives à l’échantillonnage multi habitats au prorata des macro invertébrés benthiques dans les cours d’eau. Le terme "prorata" reflète l’intention d’échantillonner tous les principaux habitats fluviaux présents sur le site de surveillance conformément aux proportions du site couvert. Il s’agit d’une façon objective de répartir les efforts d’échantillonnage sur les différents habitats. Le présent document est applicable à tous les cours d’eau, qu’ils soient artificiels, modifiés ou naturels. Il permet de prélever des échantillons comparables dans tout type de rivière, quels que soient les habitats présents. Le présent document donne des recommandations sur une approche globale plutôt qu’une méthode spécifique. Le présent document est applicable pour: — soutenir les agences de protection de l’environnement et de conservation, les offices de l'eau et les agences de l'eau afin de satisfaire aux exigences de surveillance de la DCE (Article 8, Annexe II et Annexe V) [1]; — générer des ensembles de données appropriés pour la surveillance et la création de rapports concernant les sites désignés dans la directive sur les habitats naturels et la directive Oiseaux en veillant à ce que les échantillons destinés à comparer la composition globale de la population d’invertébrés de différents types de cours d’eau soient comparables; — s'assurer que les échantillons destinés aux évaluations de la qualité environnementale dans différents types de cours d’eau sont comparables, même lorsqu’ils sont prélevés par différentes personnes; — soutenir les initiatives de gestion et de restauration des rivières; — échantillonner les sites d'une manière cohérente qui ne dépend pas de la présence de types d’habitats en particulier; — une stratégie conviviale de collecte de données biologiques en fonction de la répartition des habitats; — comprendre la répartition des types de communautés biologiques dans les différents types physiques de cours d’eau; — s'assurer de la qualité à partir de l’écart par rapport à une référence, comme adopté dans la directive cadre européenne sur l’eau [1].

Dieses Dokument gibt eine Anleitung zur pro-rata Multi-Habitat-Probenahme von benthischen Makroinvertebraten in Fließgewässern. Der Begriff „pro-rata“ spiegelt die Zielsetzung wider, alle an einem Monitoringstandort vorhandenen Haupthabitate in Flüssen entsprechend dem Anteil der Probenahmestelle, den sie abdecken, zu beproben. Es handelt sich um ein objektives Verfahren zur Aufteilung des Aufwands für die Probenahme auf die verschiedenen Habitate. Dieses Dokument ist anwendbar für alle Fließgewässer und umfasst künstliche, veränderte und natürliche Fließgewässer. Es ermöglicht die Entnahme vergleichbarer Proben aus jeder Art von Flüssen, unabhängig von den vorhandenen Habitaten. Dieses Dokument gibt einen allgemeinen Ansatz statt eines spezifischen Verfahrens vor. Dieses Dokument ist anwendbar, um:  Umwelt- und Artenschutzbehörden, bei der Einhaltung der Überwachungsanforderungen der Wasserrahmenrichtlinie (Artikel 8, Anhang II und Anhang V) [1] zu unterstützen;  Datensätze zu erstellen, die für die Überwachung und Berichterstattung von Probenahmestellen geeignet sind, die im Rahmen der Habitat-Richtlinie und der Vogelschutzrichtlinie ausgewiesen wurden, um sicherzustellen, dass Proben für den Vergleich der Gesamtzusammensetzung von Wirbellosen aus verschiedenen Fließgewässern vergleichbar sind;  sicherzustellen, dass Proben für die Bewertung der Umweltqualität verschiedener Fließgewässertypen miteinander vergleichbar sind, auch wenn die Proben von verschiedenen Personen entnommen wurden;  Initiativen zur Bewirtschaftung und Renaturierung von Flüssen zu unterstützen;  eine einheitliche Art der Probenahme an Stellen sicherzustellen, die nicht vom Vorhandensein bestimmter Habitattypen abhängig sind; als eine benutzerfreundliche Strategie zur Erfassung biologischer Daten abhängig von der Verteilung der Habitate;  die Verteilung biologischer Lebensgemeinschaftstypen über verschiedene physische Flusstypen zu verstehen;  Qualität auf der Grundlage der Abweichungen vom Referenzzustand zu beurteilen, wie in der Europäischen Wasserrahmenrichtlinie [1] festgelegt.
