Abstract

CHAPTER 7 1. RECAPITULATION To recapitulate the salient points made in the preceding chapters: The NAGP, extending from North Texas into the southern portions of the Canadian Prairie Provinces, was a vast grassland before the European settle- ment. Tall grasses dominated the subhumid eastern region and graded with decreasing annual rainfall through a zone of intermediate grasses in the central portion to short bunch grasses in the drier west. Since settlement, the grasslands of the NAGP region have been largely converted to agriculture and ranching. The region, covering some 2.25 million square kilometers, is one of abundant natural resources. It is endowed with mostly productive or potentially produc- tive soils. Deep, fertile, mollisols dominate the region. All of the NAGP’s soils are subject to wind and water erosion. The water resources of the region are substantial although not uniformly distributed; in some portions they are insuf- ficient to meet all needs. The major river systems of the region flow eastward to the Mississippi and northward to Hudson Bay. The region has one major under- ground water resource as well—the overused Ogallala or High Plains aquifer. The water resources of the region are threatened by groundwater mining, point and nonpoint
