It must be remembered that on the Great Plains the conditions vary enormously, and that few plants naturally range over the whole area, or are capable of being successfully grown in artificial plantations throughout the whole area Two special localities are frequently mentioned in the list. Arbor Lodge is the arboretum established by the late J. Sterling Morton at Nebraska City, within a few miles of the Missouri River. The University Arboretum is at Lincoln, Nebraska, on the high prairies 60 miles west of the Missouri River.
