Habitat: Woodlands and riparian areas.

Habits: The quills of porcupines are attached loosely to the body and are easily transferred to other animals where they penetrate the skin causing pain. Individuals generally are solitary. Mating takes place in the fall and a single young (usually) is born after a gestation of about 210 days. The diet consists of vegetation. In the spring leaves, flowers, roots, and other plant parts are eaten. In the winter, the diet consists almost entirely of the cambium and phloem of trees. Bacteria that are able to digest cellulose are found in the intestines of porcupines.
