22R Tordon and 2.5 gallons of 2,4,-D with 250 gallons of water. Control areas were sprayed in June. A spot spray gvn was used to concentrate control activities on target areas, reducing potential impacts to adjacent desirable vegetation. The herbicide mix, based on recommendations from the Colorado State Extension Service, was mixed and applied under the supervision of the Seneca Mine Reclamation Supervisor who is a certified applicator.

Revege to tion Monitoring Revegetation monitoring o£ permanently revege rated areas was conducted during the summer of 1995 by ESCO Associates, Inc. The 1995 annual revegetation monitoring report is submitted as a separate document (ESCO and PWCC, 19961. Grazing Long yearlings were run in the Wedge Pasture during 1995. On July 27, 205 head were placed in the wedge Pasture. On September 28, all cattle were moved oEf the Wedge pasture. Limited amounts of grazing were allowed in the Pecoco Pasture in order to protect the re-seeding work done in 1994. In addition, the Pze-law areas north of Pecoco Pasture and the old Wolf Creek spoil areas were grazed with a roving band of 500 ewes and 690 lambs. The sheep grazed those areas from August 3, 1995 until November B, 1995. This grazing scheme resulted in 328 animal unit months (AUMs) of grazing in the Wedge Pasture. Based on 1995 Wedge Pasture sampling data, the annual production was 4570 pounds per acre, resulting in 1690 AUMe available. The resulting utilization in the Wedge Pasture was 19 percent. See the 1995 Annual Revege to tion Monitoring Report Eor discussion concerning the effects of grazing in the Wedge Pasture, (ESCO, 19961.
