| Step in identification process | User & Policy Needs Assessment |
| Definition | Composition of benthic invertebrates in the European catchments and rivers network system (ECRINS), as measured by the Ecological Quality Ratio (EQR) or based on presence-absence or (relative) abundance of indicator taxa |
| Metric | (Relative) abundance of benthic invertebrates as sampled for the WFD or, if that is not available, the Ecological Quality Ratio (EQR) of benthic invertebrates in the European catchments and rivers network system (ECRINS), expressed as a numerical value between zero (low) and one (high), quantifying the ecological status of benthic invertebrate community composition and its deviation from a reference condition. The metric describes the deviation from natural benthic invertebrate communities. |
| Spatial resolution unit | ECRINS spatial units between fundamental catchment units and L2. |
| Temporal resolution unit | 3 to 6 years |
| Entity | Benthic invertebrate species with indicator value, as well as taxa without indicator value (at the level to which they are identified) as defined in the Water Framework Directive Intercalibration Technical Reports (Part 1, Rivers; Part 2, Lakes). This includes pollution-sensitive taxa such as: Mayflies (Ephemeroptera), Stoneflies (Plecoptera), Caddisflies (Trichoptera) |
