Agenda item 2:

Practical information for reporting of State-of-Environment biology data

Training on reporting of SoE biological elements in rivers and lakes

25-26 September 2013,

Skopje and Ohrid, the Former Yugoslav Republic of Macedonia

2Event, date: Reporting of SoE biology, 25-26.09.2013 Author: Jannicke Moe (NIVA)

Outline

• Building blocks of SoE biology data– Concepts– Purpose– (More details on calculation in Agenda item 4)

• Tools for reporting biology data– Excel files from NIVA (unofficial)– Web pages and templates from EEA


Building blocks of SoE biology data

– Biological Quality Elements (BQE)– National classification system:

Class boundaries and reference conditions– Ecological status class– Ecological Quality Ratios (EQR) - national and normalised

4

Biological Quality Elements (BQEs)

BQEs for which EEA requests data:•Phytobenthos in rivers (PB)

– Main pressure: eutrophication

•Macroinvertebrates in rivers (MI)– Main pressure: general degradation

•Phytoplankton in lakes (PP)– Main pressure: eutrophication

•Macrophytes in lakes (PP)– Main pressure: eutrophication

– Other main pressures: Acidification, Hydromorphology

National classification system:Reference value and class boundaries

Hypothetical metric:•Metric value: 15•Reference value: 20•Class boundaries for ecological status:

– High/Good = 17 – Good/Moderate = 11 – Moderate/Poor = 7 – Poor/Bad = 4

•Worst possible value: 0•Best possible value: 20 (?)

METRICEQR

(NATIONAL)

H/G

M/P

P/B

• WFD requires calculation of EQR values

• EEA requests EQR values for SoE biology data

• A (national) EQR value for a metric is the ratio between the measured value and the reference value

8

National EQRs

• National EQR is normally in the range 0 (bad) - 1 (high)– Can also exceed 1 !

• For metrics that decrease with the pressure gradient:EQR = measured value divided by reference value ("Method 1")

• For metrics that increase with the pressure gradient: EQR = reference value divided by measured value ("Method

2")or

alternative method ("Method 3")

• (More details in session 4)


9

• Normalisation adjusts the nationalEQR values relative to the set of normalised class boundaries:– H/G = 0.8

– G/M = 0.6

– M/P = 0.4

– P/B = 0.2

EQR (NATIONAL)

NORMALISED EQR

10

Why do we normalise EQR values?

• Normalised class boundaries are common for all countries

• Benefits of normalised EQR (nEQR):– Can be compared across countries

– Useful for trend analyses

– Can more easily combine metrics for one Biological Quality Element

• E.g. Norway has 4 metrics for phytoplankton, combined as nEQR

– More informative about ecogical state relative to class boundaries• nEQR >0.6 always means Good status or better

– Can be used for trend analyses (in future)

• The process is relatively new - no official documentation available


11

Should countries report national or normalised EQRs?

• Biology data now are integrated with Rivers / Lakes databases, and can be linked to pressures, nutrients and hazardous substances through a common Stations table.

• Two types of biology data:– Ecological quality ratios– Additional metrics (lakes only)
