grass. Both of these species provide good forage for cattle. Warm season grasses were also well <br />represented including blue grama, and red three awn. It should be noted that sampling occurred <br />relatively early in the growing season for warm season species. However, it is interesting to note <br />that the dominant grasses at the loadout in 2006 were equally western wheatgrass and blue grama <br />both native species more tolerant of drought. Smooth brome, an introduced species, did not <br />contribute to the cover at the loadout and its' relative cover at the portal was much less in 2006 <br />than in 2007. <br />Relative cover of forbs at the portal was only 0.5% in 2006 and 7.7% in 2007. At the loadout <br />relative forb cover was 3.2% in 2006 and 10.3% in 2007. These numbers again reflect the <br />change in climatic conditions between the two years. None of the forb species are listed on <br />Fremont Counties noxious weed list. <br />Summary <br />When the Twin Pines Mine site was permitted in 1984 it was a drastically disturbed area with <br />only IO % to 20% cover characterized by introduced annual forbs and scattered rabbitbrush. In <br />contrast the post reclamation vegetation cover under extreme stress in 2006 was 20% at both the <br />portal and loadout. Under better conditions in 2007 vegetative cover at the portal was 30.2% and <br />at the loadout 40.6%. Both reclaimed areas aze characterized by native species indigenous to <br />Fremont County. Data collected from the reclaimed mine site indicates the area is in much better <br />condition now than when the abandoned contour strip pit was permitted in 1984. <br />In 2007 the production values far exceeded the success standard of 200 pounds air dry herbage <br />per yeaz. Although the standazd was not achieved in 2006 the extreme drought conditions would <br />explain this. With the more favorable conditions in 2007 the standazd was far exceeded by 667 <br />pounds/acre at the portal and by 749 pounds/acre at the loadout. <br />The reclaimed vegetation represents a native, diverse plant community that sustains the post <br />mining land use of rangeland. Weeds are not a problem at the reclaimed mine site contributing <br />very little to the overall plant community. No erosion problems were observed at either the <br />portal area or at the loadout. The historic mine site has been reclaimed to a condition much <br />better than what it was in 1984 when the site was permitted. The Division believes the reclaimed <br />Twin Pines Mine Site is capable of self-generation and plant succession in accordance with the <br />requirements of the Colorado Surface Coal Mining Reclamation Act. <br />5 <br />
