3. EWEA Vice-President Jos Beurskens, 2001 “ We need to avoid the situation in the Netherlands where one faction wants to save nature and the other to introduce renewables. If you don’t bring them together it will be disastrous.”

4. Potential environmental effects of offshore windfarms SeabedBirdsSeascape and coastal character Coastal processes Fish and fisheries Visual Beach zone coastal habitats Marine mammals Historic landscape Water qualityCollisions Exclusions Amenity and water use

5. Uncertainties – the main ones! Birds – displacement, barrier effect collisions Fish – electromagnetic effects; change in fishing effort Marine mammals – underwater noise Seascape – how evaluate, layout? Cumulative assessments – how?

9. Sharks, skates and rays Will windfarm cables affect behaviour or populations? Many species depleted in UK waters Use inshore sandbanks for feeding, breeding, nursery areas Lab tests show avoidance and attraction Shielding and burial of cables

10. Seascapes

11. Stages of assessment Delineate seascape unit Visual analysis Describe - marine, coastline, hinterland Identify seascape character Evaluate – quality, value, capacity

12. Dynamism and variability Scale and distance Different sea to land/land to sea Visual movement Historic and cultural aspects Functions and uses
