RIVPACS

River Invertebrate Prediction and Classification System (RIVPACS)

'Pristine' freshwater sites are sampled to collect information on physical characteristics, chemistry and macroinvertebrates. This information is then used to predict what invertebrates are present from samples of physiochemistry from other sites.

This classification of freshwater sites based on the macroinvertebrate fauna was first derived in 1977. Since then it has been developed and updated with addition of a wider range of freshwater sites.
