Abstract
In the last years, in the Northern Pre-Urals there have been significant changes in the population dynamics of forest voles. In the foothill area the abundance of red vole decreased, and that of bank vole increased significantly, as a result of which there was the change of dominant species. In the nearby lowland areas abundance of the bank vole population remained stable, and that of the red vole increased. The main reason of these changes was the transformation of the environment under the influence of global climate change. Most of all it affected the coniferous forests of the foothills and less - the forest lowlands. As a consequence, response of the various species of voles to these changes in different landscape areas were non-identical.
