short record of sampling precludes any observation or speculation regazding long-term trends <br />at this time. <br />4.5.5.2002 Reclamation Areas <br />Quantitative sampling was conducted in the 2002 reclamation azeas for the first time this <br />season. The small number and short duration of sampling precludes any observation or <br />speculation regarding long-term trends at this time. <br />5.0 SUMMARY <br />Quantitative monitoring of the 1998 reseeded or interseeded areas, the 1999, 2000, and 2002 <br />reclamation areas, and the Osgood sand reference azea in 2005 revealed that the 1998 azeas <br />met the requirements for final revegetation success criterion for total vegetation cover while <br />the 1999, 2000, and 2002 reclamation azeas did not. <br />With regard to total herbaceous production, the 1999 and 2002 azeas met the final <br />revegetation success standazd for herbaceous production. The 2000 reclamation areas and the <br />1948 areas did not meet the final revegetation success criterion for herbaceous production. <br />Of the revegetated areas sampled in 2005, none of the azeas sampled could meet the species <br />composition revegetation success criterion (including the Osgood sand reference azea). <br />Though the reclamation azeas did not meet the cover or species composition success criteria, <br />• it was concluded that the 1998 and 1999 areas have established a diverse, effective, and <br />permanent vegetation cover of the same seasonal variety native to the azea and aze capable of <br />self-regeneration and plant succession in accordance with the requirements of the Colorado <br />Surface Coal Mining Reclamation Act. The 2000 and 2002 reclamation areas have been <br />sampled for three years and one yeaz respectively and do not show any long-term trends. <br />6.0 PEST AND DISEASE INSPECTIONS <br />Four quarterly inspections were conducted at the Keenesburg Mine to evaluate the presence <br />or potential for pest or disease infestations or outbreaks. The inspections were conducted on <br />Mazch 17, June 23, August 8-16, and December 5, 2005. Inspection reports from those <br />inspections aze located in the appendix. <br />During those inspections no disease conditions at any of the reclaimed and revegetated azeas <br />were identified. No plant pests were found which were affecting the growth of the <br />vegetation. No baze areas, or azeas which appeared to be affected by infestation or blight <br />were found during the inspections. <br /> <br />Coors Energy Company Keenesburg Mine Page 27 <br />2005 Revegetation Monitoring Report <br />
