The northern region of Arizona provides rocky slopes and coniferous forests, which are able to accommodate the state's rodent population. Temperatures are cooler throughout the year in northern Arizona due to the region's high elevation. Only certain spots in southern Arizona, such as Mount Graham, are habitable for rodents. The Arizona Game and Fish Department track the state's rodent population to ensure their survival.
Stephen's woodrat, or Neotoma stephensi, is only found in the mountainous regions of northern Arizona, northwestern New Mexico and southern Utah. These rodents live at the base of trees in rocky environments. Stephen's woodrats have hair on their tails, which is indicative of rats native to the Western Hemisphere. The diet of the herbivorous Stephen's woodrat consists of berries, seeds and vegetation of its home tree.
Found in Northeast Arizona, long-tailed voles, or Microtus longicaudus, are small rodents with tails approximately half of their body length; a long-tailed vole's body length is approximately 6 to 8 inches.

Also called the tassel-eared squirrel, Abert's squirrel primarily lives in Colorado, but is also found in ponderosa pine and douglas-fir forests in northern Arizona.

The tip of this squirrel's ears have tassels less than an inch tall. When they mature, Abert's squirrels grow up to 2 feet in length.
Arizona Chisel-toothed Kangaroo Rat
