America's Northern Plains
An Overview and Assessment of Natural Resources
United States Department of Agriculture
Natural Resources Conservation Service
May 1996
This brochure provides a general overview of the basic natural land resources in the Northern Plains region and their sustainability over time. It also describes the primary external forces (both natural and human caused) which are likely to affect those resources and it identifies projected changes in the resource base.
