Figures 1 and 2 illustrate the location of the reference and reclaimed <br />areas and sample point locations for each area sampled. <br />During the initial overview of the sampling sites it was observed that Area 10 had burned <br />and while perennial vegetation was sprouting, it was concluded that this area should not <br />be included in quarttitative sampling this year. To augment this years monitoring, the two <br />areas revegetated in 1999 (Areas 5 and 9) were proportionally sampled. <br />In the areas reclaimed in 1985, 1986, 1987, 2000, and 2002 a qualitative evaluation of <br />. revegetation success was undertaken this year. The 1985, 1986, and 1987 areas were <br />previously monitored (1994-1998) and after successfully meeting revegetation success <br />criteria, were released from the Phase II liability requirements by the Colorado Division of <br />Minerals and Geology August 11, 1998. This year, qualitative evahtation of these areas <br />included estimating vegetative cover, herbaceous production, and identifying the dominant <br />plant species. Any locations or trends in vegetation developmem that required attention <br />were also noted. The areas revegetated in 2000 (Areas 6 and 19) and 2002 (Area 25) <br />were qualitatively evaluated this year. Area 29 was seeded in the autumn of 2003 and was <br />not evaluated. <br />The Osgood sand reference area was measured and mapped in the field in 1994 by Savage <br />and Savage staff; and this scaled drawing of the reference area was used. On the scaled <br />drawing, a Cartesian coordinate grid (50x50 feet) was established. Computer generated <br />random ntunbers were used to establish a pool of x,y coordinates. Ten vegetation cover <br />and fifteen herbaceous production sample locations were randomly established for the <br />reference area. Sample sites were located in the field through compass triangulation and <br />pacing from known landmarks. <br />• <br />CooroEnergyCompany Page 8 <br />?A03 ReYegetation Monitoring Report <br />
