Microtus oeconomus, Tundra Vole, Fjellrotte. 13cm.
Quite common in the higher forests and moorland zones. They prefer more swampy areas than the field vole and live higher up.
They eat sedges and other aquatic plants. In winter they eat the roots of these plants.
Their nests is a sphere of grasses and moss above the ground in swampy areas, otherwise they nest in an extensive tunnel system. They have similar population explosions to the lemming and field vole, every 3-5 years. The sexes are alike.
They can live for 2 years, but usually survive less than 1.
