Ecological Importance
As with many other small mammal species, M. pennsylvanicus plays important ecological roles. The meadow vole is an important food source for many predators, and disperses mycorrhizal fungi. It is a major consumer of grass and disperses grass nutrients in its feces. After disruptive site disturbances such as forest or meadow fires, the meadow vole's activities contribute to habitat restoration. It prefers open, nonforest habitats and colonizes such open areas created by fire or other clearing disturbances. Very few meadow voles are found in forest or woodland areas. In newly opened areas, it is quite abundant. In these new open areas, the vole quickly becomes a food source for predators.

Famous quotes containing the words ecological and/or importance:
“The question that will decide our destiny is not whether we shall expand into space. It is: shall we be one species or a million? A million species will not exhaust the ecological niches that are awaiting the arrival of intelligence.”
—Freeman Dyson (b. 1923)
“More than ten million women march to work every morning side by side with the men. Steadily the importance of women is gaining not only in the routine tasks of industry but in executive responsibility. I include also the woman who stays at home as the guardian of the welfare of the family. She is a partner in the job and wages. Women constitute a part of our industrial achievement.”
—Herbert Hoover (1874–1964)
