River macroinvertebrate metric: ASPTBackground information
Event, date: Reporting of SoE biology, 25-26.09.2013 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:http://en.wikipedia.org/wiki/Biological_monitoring_working_party

• The metric ranges from -100 (worst) to +100 (best).

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, 25-26.09.2013 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]

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...

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

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]

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 0.2 + [Lower nEQR cb] [Upper EQR cb] - [Lower EQR cb]
• Normalised EQR should not exceed 1– values >1 are rounded down to 1.

5) Filling in EEA templates
Tools:
Templates Rivers.xls and Lakes.xls (can be downloaded from DD).
Data in Excel files delivered 2012 from Norway and Macedonia: NO_Phytobenthos_Rivers_2011.xls, Prespa_Lake_2010.xls, Ohrid_Lake_2011.xls (can be downloaded from CDR).
How to use the tools:Transfer data delivered in 2012 into the templates for 2013. Make sure that data are put into the correct tables and columns.
(NB: There are changes in the template format from 2012 to 2013).
25
Download most recent EEA Excel template
Event, date: Reporting of SoE biology, 25-26.09.2013 Author: Jannicke Moe (NIVA)
26
Fill inn the relevant tables
Event, date: Reporting of SoE biology, 25-26.09.2013 Author: Jannicke Moe (NIVA)
27
Use of excel templates from EEA
• Always download and use most recent version• Do not change format (sheets, columns, headings, etc.)• Report both data and class boundaries in the correct
scale (EQR)Excel template does not contain any built-in tools for calculation or checking of consistency with DD
• Deviations from DD can be discovered by automatic quality assessment (QA) directly after delivery to CDR
• Automatic feedback should be checked; if necessary correct and redeliver data
