• Savage and Savage <br />Memorandum <br />To: Donald W. MacDonald, Coors Energy Company <br />From: Michael Savage, Savage and Savage, Inc. <br />Date: August 15, 2002 <br />Subject: Thvd Quarter 2002 Pest and Disease Inspection; Keenesburg Mine <br />File #: C-81-028 <br />On August t5, 2002 I inspected the reclaimed and revegetated areas at the Keenesburg <br />Mme for evidence of plant pests or diseases that could affect the re-established vegetation <br />at the Keenesburg Mine. <br />All reclaimed and revegetated areas of the mine were inspected by vehicular and <br />pedestrian means. I did not identify any disease conditions at any of the reclaimed and <br />revegetated azeas. Nor did I identify any plant pests which had affected the gowth of the <br />vegetation during the past growing season. No bare areas, or azeas which experienced any <br />infestation or blight were found during the inspection. <br />• The extremely dry conditions have impacted vegetation growth at the mine in several <br />ways. Revegetated areas reveal little overall currem yeaz growth in the cool season plant <br />species. Warm season plant species are showing some growth but will not produce <br />significant flowers or seed this season. The lack of growing season moisture (total 2002 <br />precipitation through July is 4,28 inches, and September-July precipitation was 6.46 <br />inches, lowest recorded) has had the positive benefit of largely curtailing cheatgrass and <br />annual fort growth, Tn several areas, this has removed competition and allowed <br />establishment of native perennial warm season graminoids. <br />c: Keenesbnrg Pest and Disease Inspection Fite <br />• <br />AHR-2002 -43- <br />
