They typically make a nest in a burrow underground. The bank vole is one of the most important prey species for many predators, thus the small bank vole plays a big role in our ecosystem.
The bank vole is a vigorous species. Their population size in Finland varies with a relatively regular cycle of a few years. The bank vole is common throughout almost all of Europe.
