Water quality - Guidance on pro-rata Multi-Habitat sampling of benthic macro-invertebrates from wadeable rivers
This European Standard gives guidance on procedures for the pro rata Multi-Habitat-Sampling (MHS) of benthic macro invertebrates in wadeable rivers and streams. The term "pro-rata" reflects the intention to sample adequate proportions of riverine habitats with reference to their percentage occurrence.
The pro-rata MHS technique does not replace other techniques, but is rather, alongside other applications, a fundamental requisite of some multi-metric assessment approaches used to evaluate the ecological status of running waters. The method described in this document is one of the possible techniques among the existing pro-rata MHS techniques.
The MHS methodology is based on Rapid Bioassessment Protocols [1], the procedures of the Environment Agency for England and Wales [2], the Austrian Guidelines for the Assessment of the Saprobiological Water Quality of Rivers and Streams [3], the AQEM sampling manual [4], the AQEM & STAR site protocol [5], EN 27828, the Austrian Standards M 6232 and M 6119-2 [6], [7], the German Standard DIN 38410-1 [8] and the French Standard XP T90-333 [9].
This European Standard also describes in a detailed manner how to sample different habitats that might be suitable for sampling approaches other than Multi-Habitat-Sampling.

Qualité de l'eau — Lignes directrices pour l’échantillonnage des macroinvertébrés benthiques en cours d’eau peu profonds au prorata des surfaces de recouvrement des habitats présents
La présente Norme européenne fournit des lignes directrices sur les modes opératoires d'échantillonnage multi-habitats au prorata des surfaces de recouvrement (MHS) des macro-invertébrés benthiques des rivières et cours d'eau accessibles à pied. Le terme « prorata » indique l'intention de prélever des proportions appropriées d'échantillons de substrats de rivière en se basant sur leur pourcentage de recouvrement.
La technique d’échantillonnage MHS au prorata ne remplace pas les autres techniques, elle constitue plutôt, parallèlement aux autres applications, une condition préalable fondamentale de certaines approches d'évaluation multimétrique utilisées pour déterminer l'état écologique des eaux courantes. La méthode décrite dans le présent document est l'une des méthodes possibles parmi les techniques d'échantillonnage MHS au prorata existantes.
La méthodologie MHS est basée sur les protocoles de bioévaluation rapide [1], les modes opératoires de l'Agence anglo-écossaise de l'Environnement [2], les Directives autrichiennes relatives à l'évaluation de la qualité saprobiologique des rivières et des cours d'eau [3], le manuel d'échantillonnage AQEM [4], le plan d'échantillonnage sur site AQEM & STAR [5], l'EN 27828, et les normes autrichiennes M 6232 et M 6119-2 [6], [7], la norme allemande DIN 38410-1 [8] ainsi que la norme française XP T90-333 [9].
La présente Norme européenne décrit également une méthodologie détaillée pour échantillonner différents habitats susceptibles d'être adaptés à des approches d'échantillonnage autres que l'échantillonnage multi-habitats.
Kakovost vode - Navodilo za vzorčenje bentoških nevretenčarjev v sorazmerju z zastopanostjo habitatov v prebrodljivih rekah
Ta evropski standard vsebuje navodila za postopke vzorčenja bentoških nevretenčarjev v sorazmerju z zastopanostjo habitatov (MHS) v prebrodljivih rekah in potokih. Izraz »v sorazmerju« odraža namen, da se vzorčijo ustrezni deleži rečnih habitatov glede na odstotek njihovih pojavitev. Tehnika vzorčenja v sorazmerju z zastopanostjo habitatov ne nadomešča drugih tehnik, pač pa se med drugim uporablja kot temeljni pogoj za nekatere multi-metrične pristope ocenjevanja, ki se uporabljajo za vrednotenje ekološkega stanja tekočih voda. Metoda, opisana v tem dokumentu, je ena od možnih tehnik vzorčenja v sorazmerju z zastopanostjo habitatov. Metodologija vzorčenja z zastopanostjo habitatov temelji na protokolih za hitro biotsko vrednotenje (Rapid Bioassessment Protocols) [1], postopkih okoljske agencije Anglije in Walesa (Environment Agency for England and Wales) [2], avstrijskih smernicah za vrednotenje saprobiološke kakovosti vode rek in potokov (Austrian Guidelines for the Assessment of the Saprobiological Water Quality of Rivers and Streams) [3], priročniku za vzorčenje AQEM [4], protokolu za lokacijo AQEM & STAR (AQEM & STAR site protocol) [5], EN 27828, avstrijskih standardih M 6232 in M 6119-2 [6], [7], nemškem standardu DIN 38410-1 [8] in francoskem standardu XP T90-333 [9]. Ta evropski standard podrobno opisuje tudi način vzorčenja v različnih habitatih, ki bi lahko bil primeren za druge pristope k vzorčenju, ne za vzorčenje z zastopanostjo habitatov.

The pro-rata MHS technique does not replace other techniques, but is rather, alongside other applications, a fundamental requisite of some multi-metric assessment approaches used to evaluate the ecological status of running waters. The method described in this document is one of the possible techniques among the existing pro-rata MHS techniques. The MHS methodology is based on Rapid Bioassessment Protocols [1], the procedures of the Environment Agency for England and Wales [2], the Austrian Guidelines for the Assessment of the Saprobiological Water Quality of Rivers and Streams [3], the AQEM sampling manual [4], the AQEM & STAR site protocol [5], EN 27828, the Austrian Standards M 6232 and M 6119-2 [6], [7], the German Standard DIN 38410-1 [8] and the French Standard XP T90-333 [9]. This European Standard also describes in a detailed manner how to sample different habitats that might be suitable for sampling approaches other than Multi-Habitat-Sampling. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

5 cm to 10 cm for finer substrates (psammal, pelal, fine particulate organic matter (FPOM)),
10 cm to 15 cm for intermediate sized substrates (akal, microlithal, coarse particulate organic matter (CPOM)), or
15 cm to 20 cm for larger substrates (macrolithal; living parts of terrestrial plants). A distribution of 20 sampling units proportional to the share of habitats means if the total habitat in the sampling area consists of 50 % psammal (sand), then 10 "sampling units" are withdrawn from this substrate. The categories of habitat composition follow the descriptions given in Clause 3.
If a square net of 25 cm × 25 cm is used, the sampling procedure equals a sampled area of approximately 1,25 m2 of the stream bed (Figure 1).
