Few, if any, would believe this small rodent may be playing a key role in the study of monogamous relationships between adults, may have caused a fire which destroyed over 16,000 acres and 60 homes, and could be providing critical information regarding global warming. However, these 'accomplishments' are all credited to the comm

a result of these studies, Ms. Spaeth believes a decline in the Montane Vole population could readily indicate improper management of the grasslands (such as overgrazing). It could also indicate global warming if the climate were to become hotter and drier thus creating less suitable Montane Vole habitat.

Apparently the Forest Service stopped the power company from clearing the trees from underneath the power lines which ran through Forest Service land. Their reason? To protect the voles which were an important food source for the Spotted Owl.
