Influence of Transport Infrastructure on Nature

Abstract: Germany has made much effort to mitigate habitat fragmentation caused by transportation infrastructure. Examples are wildlife underpasses, overpasses, river crossings and tunnels at road and railway systems. More than 50 overpasses have been built during the last 20 years. Most of them mitigate fragmentation effects of new roads or highways, respectively. River passes have been upgraded with top soil and veg­etation to connect biotopes. In order to prove the invested efforts, three large and several minor investigation projects have been carried out. The main results found their way into a German guideline: Construction of Fauna Passages at Roads. It outlines not only the demands of red deer, roe deer, wild boar, badger, European otter and other animals with large and small habitats. But it distinguishes between passes for single species and those to connect habitats with all their inventory.
