attached weed control daily log spreadsheet for more detailed information of the 2007 herbicide application. <br />. Actual field logs are on file at the mine site. <br />• Grazing <br />Cattle (170 cow/calf pairs) were moved on to the Seneca II-W Salt River Reclaim Pasture for 14 days <br />between September 9~ and September 23~. Then the cattle (200 cow/calf pairs) were moved to the Seneca <br />Reclaim Top Pasture for 15 days between September 23~ and October 9~. This grazing scheme resulted in a <br />total of 179 AUMs for 2007.
