South Dakota Grasslands, Their Condition and Management

Statewide surveys of South Dakota grasslands have been made in 1940, 1942, and 1946. The stocking rates presented on the map (center pages) were determined from the 1946 survey, based upon the past ten years\u27 actual use-grazing records from representative farms and ranches. The range and pasture condition method of study was introduced into the 1946 resurvey of South Dakota grassland. The condition approach is much more usable by stockmen and agricultural workers alike than former methods of making grassland inventories. The 1946 inventory of range and pasture condition shows South Dakota grasslands are near the peak of productivity. Above-average rainfall is largely responsible for this condition. When the precipitation cycle becomes less favorable and dry years come and they surely will-then only good management of our grasslands can maintain their productivity and prevent the unfavorable conditions of the mid-thirties. Further studies and follow-up surveys will be made periodically to keep abreast of changes in condition and stocking rates for South Dakota grassland
