From your description you may be dealing with voles. If you are noticing holes about the size of a silver dollar, suspect voles. They are a type of meadow mouse that feeds on the roots of trees, shrubs, and herbaceous plants. Control involves trapping with mouse traps baited with apple slices or peanut butter. See our publication on voles extension.umd.edu/publications/PDFs/FS654.pdf
