Habitat and niche
M. pennsylvanicus is the most widespread of any other rodent group, ranging from Mexico to the Arctic.[6] They can be found throughout Northern and Eastern United States and right across Canada, from Newfoundland and Labrador to British Columbia, including the Yukon Territory and Alaska. Because of the broad range of climates found within these areas, M. pennsylvanicus has varying phenotypic characteristics depending on the environment, having a larger body size in cold climates and a smaller body size in warmer climates.[7] They often live in open fields as opposed to heavily wooded areas, and are abundant in areas with a high degree of plant cover.

Diet
The Meadow Vole is a herbivore, feeding mainly on the grasses that are abundant in its environment. When grass is not readily available, such as during the winter months, the meadow vole may often gnaw on tree bark as a source of nourishment.[12] They often will eat nuts and seeds when available.
