Man-made structures provide a surface on which a variety of marine life can live. Offshore wind turbines are supported on a ‘monopile’, which is a long steel tube measuring 4 metres in diameter. Many plants and animals need a hard surface to attach to, and these monopiles can be a perfect base for them. Conditions change at different levels of the monopile, creating different types of habitat or ‘zones’, each with a unique selection of marine life. These zones can be plainly seen on the monopiles, each providing a habitat for different plants and animals. The open water and sea bed around wind turbines is also home to a wide range of creatures, each living in a habitat, which suits its way of life. Many are attracted to these areas by the diversity of potential prey living on and around the monopiles.
