San Bernardino County is the largest county in the United States. It is an mostly arid inland county and includes much of the San Bernardino Mountain Range, the entirety of the Mojave National Preserve, and small portions of both Joshua Tree and Death Valley National Parks, giving it a great deal of desert and mountain diversity. It also includes the cities of San Bernardino and Victorville in its southwest corner. This list contains all of the plants, animals, and other wildlife I have photographically documented in the county.
