    20. 20. “For bottlenose dolphins, auditory injury would only have occurred within 100m of the pile-driving…and behavioural disturbance, defined as modifications in behaviour, could have occurred up to 50km away” Assessing underwater noise levels during pile-driving at an offshore windfarm and its potential effects on marine mammals, Bailey et al, 2010

    25. 25. “Overall, less than 1% of the ducks and geese fly close enough to the turbines to be at any risk of collision…” Avian collision risk at an offshore wind farm, Desholm et al, 2005
    26. 26. “…efforts should also be made to assess the cumulative impacts of small-scale local effects on the different geographically-defined avian populations…”
    27. 27. ? not enough data
    28. 28. “…direct habitat loss is between 2% and 5% of the total development area…potential positive impacts may arise from the creation of refuges free from fishing pressure” Impacts of climate change and selected renewables on EU biodiversity and Natura 2000 network, Keder et al, 2009 http://en.wikipedia.org/wiki/File:Flounder_camo_md.jpg
