Since Slovakia joined the EU, a notable increase in traffic volume and the development of the road infrastructure has been recorded. This process is directly connected with the increase of wildlife - traffic collisions and disruption of migration corridors for the larger mammals. Until recently, the government bodies responsible for the construction of roads and traffic safety ignored the issue of animals on the roads. At an important meeting in 1997 we expressed concern about this problem of wildlife on the roads. The answer we received says it all ”Dear colleague, do not worry, your animals will get used to the cars.” What happened a few years later is shown in the following graphs. Until 2008 wildlife traffic mortality was not recorded. Based on our recommendations, since 2008 the National Forest Centre in Zvolen has started to keep records on traffic mortality of wildlife from all hunting grounds in Slovakia. The data is included in the National Hunting Statistics. Because Slovakia was lacking information about wildlife corridors, we conducted a migration study focused on the identification of crossings between highways and wildlife habitats. The output of this study was published in the book “Brown bear corridors in Slovakia” (2007). Maintaining the possibility of migration through these crossings with the help of ecoducts can secure the habitat connectivity across the country.
