Roads and railways connected to the fixed link over the Fehmarnbelt create new barriers in the landscape. These can have an impact on the way animals and plants spread in the area. What is affected? One example is the agile frog, which migrates between its wintering grounds in deciduous forest and waterholes where it breeds. Another example is bat, which orientate themselves in relation to trees and watercourses when moving around in the landscape.

The chances improve when a passage is laid along existing landmark lines like watercourses, forest fringes and hedgerows along which animals often move. |
It is not just the link itself that may constitute a barrier. Light, noise, and pollution can also function as indirect barriers by making an area unsuitable as a habitat or feeding ground for animals.
