The use of contour furrows for controlling runoff and for restoration of depleted pastures has been advocated widely. A relatively small amount of experimental data is available to show the response of pasture vegetation after such a treatment. Complete protection from grazing to restore the vegetation of pastures has been a recognized practice. A study of contour furrows and varied protection on a mixed prairie type of vegetation was made possible by a series of experiments on the control of runoff and erosion, conducted by the Hydrological Division of the Soil Conservation Service.
In 1941 a study was made of the vegetation on two pastures in which different methods of restoration had been in effect since 1939. The purpose of this study was to determine the status of recovery of the pastures, and to establish a basis for measurement of later changes in the vegetation.
