What is BS EN 16150 -  Multi-Habitat sampling of benthic macro-invertebrates  about?

BS EN 16150 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 BS EN 16150  is one of the possible techniques among the existing pro-rata MHS techniques.
