The common vole is hardly restricted in means of distribution and habitat and inhabits large areas of Eurasia but, apart from the Orkney vole, not the British Isles. As Microtus arvalis followed human civilization, primary and secondary habitats can be distinguished. The primary habitats are everything but dense forests, such as meadows, heath lands, and fallow land. The secondary habitats are mainly agricultural fields, where shallow sloped areas are preferred. The natural food of the common vole is grass, but it also feeds on many agricultural crops (within secondary habitats) and here its reproduction is faster than in primary habitats.
They are listed as least concern
There are around 155 species of voles, though whether any other of these are added, we will wait and see
