• Regulating: • Biodiversiy • Integrity/No Fragmentation
• Cultural: • Recreation
Ecosystem services
sensitivity to wind farm
• Maximum value = Destruction of the ecosystem service
• Minimum value = No impact
STEP 3
STEP 1
Data Source Model • Advantages
• complete spatial coverage • vertical profile
• Disadvantage • large uncertainty on vertical
profile à Measurement: tower + sodar
accurate vertical profile
