In several locations within both areas, significant perennial graminoid growth was present, <br />particularly Bouteloua gractlis and Panicum virgatum. In areas bordering native range, <br />• annuals (Kochia scoparia and Bromus tectorum) dominated. As noted last season, <br />Kochia scoparia serves as a cover crop and moisture holder (particulazly snow) for <br />perennial graminoids, providing shade and desiccation protection for developing perennial <br />graminoids. Total vegetation cover was estimated at 40 percent. <br />3.2.5 2002 RECLAMATION AREA <br />In 2002, a 0.66 acre azea east of the southern segment of B Pit was seeded to the <br />perennial seed mix. This area bounds the active haul road to B Pit and reclaimed and <br />revegetated azeas. Initial observations revealed typical annual growth during the first <br />season with small perennial Bass sprouts below. <br />3.3 COMPARISON OF RECLAII~IED AND REFERENCE AREAS <br />Monitoring of the revegetated areas allows for the identification of vegetation community <br />development trends during the extended liability period. This evaluation also assists in <br />decisions regarding yearly grazing, husbandry practices, interseeding, fertilizing, and weed <br />management. Comparison of the reclaimed area values for vegetation cover, herbaceous <br />production, and species composition with the values from the reference azea or standazd, <br />indicates whether revegetation has been successfirl, or whether additional measures need <br />to be initiated to enhance vegetation community development. The tables below allow the <br />• comparison of the parameter values with the standazd to be achieved, either from the <br />reference area in the case of vegetation cover and herbaceous production, or the <br />established standard for species wmposition. <br />Total Vegetation Cover (2003) <br />Reference 1995 Ree. 1997 Rea i99g A~ 1999 Ree. <br />Xpu 55.80 39.00 43.60 40,67 27.60 <br />5 7.69 7.96 7.99 15.16 6.69 <br />N 10 10 10 6 5 <br />Nmin 6 14 11 47 20 <br />Total Herbaceous Production (2003) <br />Refereace 1995 Rea 1997 Rec. 1998 Areas 1999 Ra, <br />~ar 130,21 148.99 163.05 148.51 142,08 <br />5 31.53 54.9? 53.91 55,36 90.45 <br />N 15 15 15 9 5 <br />Nmin 18 42 34 43 126 <br />CooroEnergyCompary Page 16 <br />2003 Revegetatbn Monitoring Report <br />
