Grazing <br />use should be rotated to rest plants from continuous winter defoliation. <br /> <br />.--- <br /> <br />N <br /> <br />Table 1 shows the result of two treatments on reducing salinity in <br />surface runoff from highly saline lands in the Upper Basin States of <br />Colorado, Utah, and Wyoming. The winter grazing treatment reflects a <br />10 percent decrease in the amount of salinity compared to the un grazed <br />condition (based on discussion with Gregg Lusby - 27). Salinity control <br />through grazing management would cost over twice as much as that achieved <br />by total removal of livestock. However, salinity control through grazing <br />management still yields nearly two dollars in benefits for everyone <br />dollar spent. The reductions in livestock shown for winter grazing <br />(grazing management) may, in many cases, be accomplished in connection <br />with proposed adjustments in use as analyzed in grazing environmental <br />impact statements (EIS), e.g., adjustments proposed in the Grand Junction <br />Grazing EIS (4). <br /> <br />10 <br /> <br />.. <br /> <br />J:;^ ~ - .-.;,-_ -",,_ _d_~ <br />
