The recommended procedures focus on 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 a minimum occurrence of 5% of total habitat. Among other applications the pro-rata Multi-Habitat-Sampling technique is a fundamental requisite of multimetric assessment approaches that evaluate the ecological status of running waters.
