Prairie Vole (Microtus ochrogaster), a state Special Concern species, is found in dry sand prairies, along fence lines, in open fields, sandy grassland terraces of large rivers, bluff prairies, abandoned farm fields, and seldom in barrens areas. Its preferred habitat seems to be native prairie sod, of which there is little left in Wisconsin. It avoids marshes and wet places. Semi-colonial, this species breeds throughout the year with a peak in July, August, and September.
