The Campestrian element predominates in three of four Great Plains faunal districts. Eastern and Neotropical elements are present only in the South Platte and Arkansas Valley faunal districts. The Eastern element is more important in the former district than in the latter, but Chihuahuan species are more prominent in the Arkansas drainage.
