3. Conclusion
This paper demonstrates that there is potential to develop a first ecosystem assessment on the basis of existing data if they are combined in a creative way.

4. Conclusion
However, substantial data gaps remain to be filled before a fully integrated and complete ecosystem assessment can be carried out.

5. Non-conclusion
The MAES process lacks scientific rigour

12. Integrated ecosystem assessment: condition and services
We need a working definition for ecosystem condition based on policy targets

14. Integrated ecosystem assessment: condition and services
Several approaches
Mapping the evidence
Detecting spatial congruence
Narratives and theoretical exercises (matrix)
Measurements

15. Why mapping is essential:
Ecosystems, ecosystem condition, ecosystem services and benefits of ecosystems are not equally distributed over space (and time)
