An armadillo invasion of Kansas is underway. Each year more sightings are reported and they now are recorded as far north as the Platte River in southern Nebraska. They are abundant enough in some areas in southern Kansas to be considered nuisances because of their burrowing habit. They prefer soft ground which in Kansas includes the Pennsylvanian sandstone and shale in the Chautauqua Hills in the southeast, the Permian redbeds in the Red Hills country in south-central, and the shales and siltstones of the Cretaceous in central and western Kansas. Because their metabolism requires a constant intake of food, they can not tolerate long periods of severe weather. The change in climate and other factors, however, favors their continued northward migration. They now have been reported from almost one-quarter of the Kansas counties.
