DistributionRead full entry
The biogeographic range of Plestiodon obsoletus (Great Plains skinks) begins in western Missouri and northwest Arkansas and extends to eastern Arizona. It reaches as far north as the southern portions of Nebraska and ends in northern Mexico. They are found in Nebraska, Colorado, Arizona, New Mexico, Texas, Oklahoma, Kansas, Missouri, and Arkansas. They are only found in the Nearctic region and specifically in the southern half of the North American Grassland Biome. Plestiodon obsoletus are most abundant in Kansas. Scattered populations are found in more northern portions of Nebraska, Iowa, and Missouri but are not connected to the main distribution. Lack of rocks coupled with a decrease of mean daily temperatures has limited distribution around these isolated populations.
