Cumulatieve effecten windparken op zee

Research into the effects of Offshore Wind Farm Egmond aan Zee (OWEZ)

Cumulative effects of wind farms at sea on birds

In order to assess the potential effects of multiple offshore wind farms in the North Sea on birds a study was carried out that used both field data and modeling techniques. Based on literature and data collected at Offshore Wind Farm Egmond aan Zee collisions were considered to have more influence on bird populations than the other main effects of disturbance or habitat loss and barrier effects.

The effects of multiple wind farms on bird populations from around the North Sea were assessed using population models. Species assessed included seabirds such as gannet, fulmar, great skua, guillemot, razorbill and puffin as well as several gull species and species that pass over the North Sea during migration.

These population models formed the basis against which the effects of multiple wind farms could be assessed. The potential effects of multiple wind farms, such as collision-related mortality, were applied to each of the populations. These potential effects were calculated based on the results obtained from the field studies at Offshore Wind Farm Egmond aan Zee.
