Event, date: Reporting of SoE biology, Author: Jannicke Moe (NIVA) PIT = periphyton index of trophic status IVi = indicator value of species i ni = number of indicator species 4,37+6,98+3,72 3 = 5,02 Example

6 River macroinvertebrate metric: ASPT Background information Event, date: Reporting of SoE biology, Author: Jannicke Moe (NIVA) Average Score Per Taxon: The ASPT equals the average of the tolerance scores of all macroinvertebrate families found, and ranges from 0 to 10. Tolerance scoring table and more information:

7 Four different metrics are combined into a single normalised EQR value Lake Phytoplankton metrics Background information Event, date: Reporting of SoE biology, Author: Jannicke Moe (NIVA) Biomass Chlorophyll a Planteplankton EQRn nEQR average nEQR Abundance nEQR nEQR Composition nEQR Cyanomax nEQR* average Species composition: PTI (Phytoplankton Trophic Index) Bloom index: Max. biomass of cyanobacteria Cyanomax nEQR is included if worse than average of nEQR for Abundance and Composition

8 TIc (Trophic Index count) represents the relationship between number of sensitive and tolerante taxa in a lake. The metric ranges from -100 (worst) to +100 (best). More information: Penning, E., B.

10 Setting ecological status with Excel tool Event, date: Reporting of SoE biology, Author: Jannicke Moe (NIVA) Formula will determine the status given the metric value and the class boundaries

Event, date: Reporting of SoE biology, Author: Jannicke Moe (NIVA) 11 3) Calculation of national Ecological Quality Ratios (EQR) from biological metrics and reference value Tools: EQR_calc_NIVA_empty_[date].xlsx EQR_calc_NIVA_answers_[date].xlsx How to use the tools: Check the formula and check the calculated EQR value against the sheet with answers.

12 Three "methods" for calculation of EQR EQR should decrease from 1 to 0 when pressure increases from best to worst Method 1: for metrics that decrease with higher pressure Method 2: for metrics that increase with higher pressure Method 3: for both types of metrics ("Methods" are my own labels - not official descriptions) Event, date: Reporting of SoE biology, Author: Jannicke Moe (NIVA)

13 Calculation of national EQR: "Method 1" For metrics with LOWER value at higher pressure The simplest case Example: ASPT (macroinvertebrates in rivers elv, general degradation incl. organic pressures) Formula:EQR = [observed] / [reference] Event, date: Reporting of SoE biology, Author: Jannicke Moe (NIVA)

14 Calculation of national EQR: "Method 1" Event, date: Reporting of SoE biology, Author: Jannicke Moe (NIVA) "Best value" "Worst value" METRIC EQR (NATIONAL) H/G P/B M/P

15 Calculation of national EQR: "Method 2" For metrics with HIGHER value at higher pressure Example: Chl-a (eutrophication) Formula:EQR = [reference] / [observed] Not ideal solution... Event, date: Reporting of SoE biology, Author: Jannicke Moe (NIVA)

16 Calculation of national EQR: "Method 2" Problem: When the formula is turnet "upside down", the EQR value becomes "distorted" The EQR value will "behave strangely" in the extreme ends of the pressure gradient Event, date: Reporting of SoE biology, Author: Jannicke Moe (NIVA) Total P Chl-a Ref Total P Ref Chl-a

17 Calculation of national EQR: "Method 3" Can be used for both types of metrics: For metrics with LOWER value at higher pressure –Example: macrophytes in lakes, eutrophication (TIc) For metrics with HIGHER value at higher pressure –Example: phytobenthos in rivers, eutrophication (PIT) Formula: EQR = [observed]-[worst possible value] [reference]-[worst possible value] Event, date: Reporting of SoE biology, Author: Jannicke Moe (NIVA)

22 Calculation of normalised EQR Generel formula for normalised EQR: (cb = class boundary for the status of the given EQR value) = ([EQR] - [Lower EQR cb]) x ([Upper nEQR cb] - [Lower nEQR cb]) + [Lower nEQR cb] [Upper EQR cb] - [Lower EQR cb] = ([EQR] - [Lower EQR cb]) x [Lower nEQR cb] [Upper EQR cb] - [Lower EQR cb] Normalised EQR should not exceed 1 –values >1 are rounded down to 1.
