SUMMARY <br />• Quantitative monitoring of the 1995 and 1997 reclamation areas, the 1998 reseeded or <br />interseeded azeas, and the Osgood sand reference area in 2002 showed that all reclamation <br />areas met final revegetation success criteria for total vegetation cover. With regazd to total <br />herbaceous production, all reclamation areas exceeded the total herbaceous production <br />value from the Osgood sand reference azea, therefore meeting the revegetation success <br />criterion for herbaceous production. Of the azeas sampled in 2002, none of the azeas <br />sampled could meet the species composition revegetation success criterion (including the <br />Osgood sand reference area). It was concluded that the reclamation azeas have <br />established a diverse, effective, and permanent vegetation cover of the same seasonal <br />variety native to the azea and are capable of self-regeneration and plant succession in <br />accordance with the requirements of the Colorado Surface Coal Mining Reclamation Act. <br />V. PE5T AND DISEASE INSPECTIONS <br />Four quarterly inspections were conducted at the Keenesburg Mine to evaluate the <br />presence or potential for pest or disease infestations or outbreaks. The inspections were <br />conducted on Mazch 28, May 30, August 15, and December 19, 2002. Inspection reports <br />from those inspections aze located in the appendix. <br />During those inspections no disease conditions at any of the reclaimed and revegetated <br />• areas were identified. No plant pests were found which were affecting the growth of the <br />vegetation. No haze azeas, or azeas which appeazed to be affected by infestation or blight <br />were found during the inspections. <br />• <br />Coors Energy Company Page 21 <br />2002 Revegetatwn Monttoring Report <br />
