and 4-9 in fortis). The graminoid increases are due to increased representation by perennials <br />• from the revegetation seed mix. The majority of fort increases aze due to representation by <br />native fortis infilling from adjacent native areas. <br />5.0 SUMMARY <br />Quantitative monitoring of the 1995, 1997, and 1999 reclamation areas, the 1998 reseeded or <br />interseeded azeas, and the Osgood sand reference azea in 2004 showed that all of the <br />reclamation areas exceeded the final revegetation success criteria for total vegetation cover. <br />With regard to total herbaceous production, all reclamation areas exceeded the total <br />herbaceous production value from the Osgood sand reference azea, therefore exceeding the <br />revegetation success criterion for herbaceous production. Of the revegetated azeas sampled in <br />2004, none of the areas sampled could meet the species composition revegetation success <br />criterion (including the Osgood sand reference azea). Though the reclamation areas did not <br />meet the cover or species composition success criteria, it was concluded that the reclamation <br />areas have established a diverse, effective, and permanent vegetation cover of the same <br />seasonal 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 />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 31, June 21, July 22, and November 23, 2004. 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 vegetation. <br />No bare areas, or areas which appeared to be affected by infestation or blight were found <br />during the inspections. <br />• <br />Coors Energy Company Page 22 <br />2004 Revegetation Mon'rtoring Report <br />
