Some researchers estimate the average population at two to four chipmunks per acre of adequate habitat. Predation does not usually have a great effect on local populations. Chipmunks can tolerate a wide range of living situations. Their population is currently holding steady. They are among our most common and best known mammals.
Few chipmunks inhabit swamps or marshland.
Habitat for chipmunks, and most other forms of wildlife, is constantly changing.
