Abstract

The purpose of the study was to find where and why two species of owls were killed by traffic along motorways. Three different factors have an important influence on the mortality of the two owl species: the biotops crossed by motorways, the road elevation and the presence of small rodents, the Common Vole (Microtus arvalis) being most numerous. In order to limit the mortality caused by motorways, it is proposed to let the bordering vegetation grow naturally.
