Artificially created animal migration passages and their effectiveness

Highways, expressway and other infrastructure have a negative impact on the surrounding population of animals. These linear structures in the landscape create impassable barriers and thus cause more or less isolated subpopulations (called barrier effect). Therefore, the newly constructed building of European highways and passages specially built for the animals, known as green bridges (ecoduct). Effectiveness of transitions is influenced by several factors (width of the bridge, the frequency of passing cars, the speed limit, etc.). This thesis deals with the efficiency of artificial crossings for wildlife and provides an overview of the results published so far
