Variation in Jacob’s index (see text for explanation) between years (centered around mid-winter for boat data) for Herring Gull Larus argentatus based on aerial (top) and boat survey (bottom) data. Indices from the pre-construction period are shown with open symbols and broken lines, indices from the post-construction period with filled symbols and full lines. Red = the wind farm area, Blue = the buffer zone, up to 2 km from the wind farm. 2005a = winter-spring 2005, 2005b = autumn-winter 2005. Variation i Jacobs index (se text för förklaring) mellan år (centrerade runt midvinter för index från båtdata) för gråtrut Larus argentatus vid flyg (överst) och båtinventeringar (underst). Index från innan vindkraftparken byggdes visas med ofyllda symboler och streckade linjer, index från perioden med parken i drift med fyllda symboler och heldragna linjer. Röd = vindkraftparken, blå = buffertzonen upp till 2 km från parken. 2005a = första halvåret 2005, 2005b = andra halvåret.
