Western red-backed vole
The body color is chestnut brown, or brown mixed with a considerable quantity of black hair gradually lightening on the sides and grading into a buffy-gray belly, with an indistinct reddish stripe on the back and a bicolored tail about half as long as the head and body.The northern limit is defined by the Columbia River, with the range extending south to around 100 km (62 mi) north of the San Francisco Bay.However, the spores are found in the vole's droppings and are deposited throughout its burrows, thus enabling the fungus to spread and form associations with uninfected trees.It has been found that in a clear-cut forest where all the dead wood and trimmings are removed, the mycorrhiza stops fruiting, the vole population dies out and newly planted trees fail to thrive.[6] The western red-backed vole plays an important role as prey to a number of species, including martens, ermines, and long-tailed weasels.
