Skunks make up a diverse group of carnivores living in a variety of habitats, have different ecological requirements, and a wide variety of behavioral and reproductive idiosyncrasies" (Skunk, 2003). The striped skunk can be found almost everywhere in the United States, as well as in Mexico. One author indicates that, "Striped skunks occur throughout North America except for the boreal forest, Alaska, coastal British Columbia, and the extreme desert southwest (Godin 1982 via Hanson 1997)" (Adams, 2002).
