The North Dakota surface mining control statute, N.D.C.C. 38-14.1-24 (17) requires that mined lands designated for postmining agricultural purposes be restored to productivity levels equal to or greater than those obtained on nonmined agricultural lands of similar soil types in the surrounding area. For lands to be rehabilitated to native grasslands, the statute requires restoration to productivity levels at least equal to those of the natural vegetation of the area. The purpose of the report was to evaluate selected harvest method approaches for estimating aboveground production. These methods are: To determine peak aboveground biomass, i.e. total peak yield, by harvesting, i.e. clipping, once or more per growing season to determine the best time of actual maximum biomass production; and To determine total amounts of aboveground production by summing peak biomasses of species or species groups.
