River Invertebrate Prediction and Classification System

Considering evidence from both field and mesocosm studies, it may be concluded that certain groups of aquatic macroinvertebrates are sensitive to pyrethroids and that there can be changes, in the short term, at the population level and above with exposure to environmentally realistic concentrations of them. It should be possible to pick up effects of this kind in natural waters using ecological profiling, for example, the River Invertebrate Prediction and Classification System (RIVPACS). There is... 

RIVPACS River Invertebrate Prediction and Classification System. 

The SOILPACS study (Weeks et al. 1998). This study investigated the feasibility of the community census approach for soils. The study concluded that a system could be constructed but substantial development was needed. In particular, full faunistic, physical, geological and chemical surveys of many (diverse) reference sites would be needed to develop a system with predictive capability. For development of the UK river invertebrate prediction and classification scheme, over 400 sites were sampled in this manner. The fact that this number would need to be matched for SOILPACS presents a substantial hurdle to development.
