Flood Plain Vegetation of the Central Missouri Valley and Contacts of Woodland with Prairie

So profoundly has this river modified the effects of the general grassland climate that in many places prairie has given way to woodland and forest. Several distinct forest communities along the river in southeastern Nebraska and adjacent parts of Kansas, Missouri, and Iowa extend for short distances over the uplands, but farther along the major streams. Most of the trees and shrubs of this forest are near the extreme western limit of their range. The extreme outposts of the forest are represented by relatively few species of trees and shrubs along the creeks and sheltered ravines which more or less dissect the hillv and rolling portions of the prairie.
