Influence of Transport Infrastructure on Nature

Abstract: The work shows an example of drastic decrease in the size of amphibian population in the town of Poręba-Żegota, situated by the busy 780 road Cracow-Oświęcim. It is a result of the area draining and, until recently, massacre of the animals, mostly in the section of the road running along post-manor ponds and an old park. In this region grey toads and grass frogs used to occur in large numbers. A rescue action, initiated in 1999, starts to give positive results. It originally involved setting up road signs “Beware of amphibians” and subsequently, the construction of plastic fences of 300 m length, guiding animals to the special baskets. Three times a day frogs were transferred to the containers and carried to the other side of the road. Moreover, the article directs attention to the conditions which special passages for amphibians should meet in the Polish climate.
Key words: roads, fauna mortality, mitigation measures, amphibians passages
