Creation of new habitats
The construction of overhead lines creates new habitats. In some locations, the power lines run through woodlands, crossing them in forest aisles. From an ecological perspective, these forest aisles can be considered "life lines".
Within these forest aisles, varied biotopes and habitats for insects, reptiles, birds and mammals may develop which are often worthy of conservation. In these newly created habitats, plants requiring special conditions such as extensive cultivation and regular clearance of undergrowth can be found – like many of the native orchids. The diversity of plant and animal species in the surrounding woodlands and agricultural land is usually considerably lower.
Electricity pylons provide birds with additional breeding opportunities. In north-eastern Germany, osprey now breed more frequently on towers than in trees. Amongst other species, falcons and ravens now use towers.
