For example, the prairie deer mouse avoids wooded areas, even if the surface layer is grass-dominated. Logging frequently has a positive effect on deer mouse populations although some studies report no change or negative effects on deer mouse abundance. Increased cover in slash and increased production of seed by annuals probably contribute to the positive effect. Most studies concluded that the size of the deer mouse home range was directly related to food supply, and varies with season. There is often, but not always, an inverse relationship between deer mouse population density and home range size.
Deer mice use and maintain several home sites or refuges within the home range.
Prairie deer mice travel over a different area within the home range on successive nights, returning to the nest on the same path used for the outward trip. The extent of travel and intensity of use of the home range varies with habitat change and loss or gain of conspecific neighbors. Home range fidelity is fairly strong. Adults shift home ranges in response to habitat alteration or disturbance. Nests are also constructed in various structures and artifacts including old boards and abandoned vehicles.
