1. Proposals of some general rules (DEMNA, INBO, IBGE/BIM, FOD)
How to integrate data from three (or more) administrative regions? A case study: Belgium
Proposals of some general rules (DEMNA, INBO, IBGE/BIM, FOD)
J.-M. Couvreur
Expert Group on Reporting
Meeting 20 th March 2013

2. 3 Administrative Regions with 3 institutions
(+ federal level dealing with marine habitats)
=> Different methodological approaches

4. Ex: 3150
(Permanent eutrophic lakes,
ponds and pools )

5. Ex: 3150
(Permanent eutrophic lakes,
ponds and pools )

6. Ex: 3150
(Permanent eutrophic lakes,
ponds and pools )

7. The general rules suggested
(Source of inspiration: ‘ Guidelines for assessing conservation status of habitats (2008) and species at the biogeographical level ’ ETC/BD (EEA))
1) Method used (1.1.2., , and so on) when different:
W or Fl
Integration 1 3 2
2) Year or period (1.1.3 ; and so on) when different : we integrate the widest period. Ex : and =>

8. The general rules suggested are (2) :
3) Reason for change  ( for example) : if they is one ‘YES’ => ‘YES’.
Reasons for change: genuine, improved knowledge, use of different method?
W or Fl
Integration
YES NO

9. The general rules suggested are (3) :
4) Trends ( ‘Area’ for example)
If values available:
Take into account the assessments in each administrative region
Sum the values of each administrative region
Produce the final assessment.
Proportion of habitat/population in each administrative region?
If at least 1 ‘unknown’:
‘majority’ in one region (ex: >75%)
Almost equal (+/- 50%) in each region
Final ‘trend’ = trend of the majority
Final ‘trend’ to be discussed between experts!
Either ‘unknown’ or ‘increasing/decreasing’!

10. The general rules suggested are (4) :
5) Threats and Pressures (2.5 and 2.6)
- Sum the lists from administrative regions => More than 20? More than 5 with ‘H’ ranking => Discussion between experts!
- If same Pressure/Threat with different ranking => if ‘majority’ in one administrative region => ranking of that region
=> if almost equal in each region => discussion between experts!

11. Ex: 3150
(Permanent eutrophic lakes,
ponds and pools )

12. Thank you for your attention!
