October 15, 2014 C- 1981 - 010 /Trapper Mine JLE <br />were not observed. DRMS verified topsoil replacement depths of the Z -A -07 and 08 parcels during the October <br />24, 2007 and April 20, 2010 inspections. The 2.2 acre Z -A -07 and the .5 acre Z -A -08 parcels were observed. A <br />dense stand of grasses have established on these parcels. The dominant grass species established were Basin <br />Wildrye, Sheep Fescue, Bromus marginatus; Mountain Brome and various Wheatgrasses. The forb Western <br />Yarrow was observed. Shrubs were not dominant within this parcel; however the adjacent Z -AB -05 parcel has <br />thick stands of Rubber Rabbitbrush established. It is likely shrubs will volunteer into these parcels in the future. <br />Bare areas were not observed. Overall, it appears vegetation has established on these parcels to support the post <br />mine land use. Rills and gullies were not observed on these parcels. <br />Parcel K -A -10 is 18.0 acres in size. The topsoil depth was evaluated during the August 15, 2013 site inspection. <br />The Division found the average depth at this parcel to be 16.75 inches. The dominant perennial grasses observed <br />were Kentucky Bluegrass, Wheatgrass and Sheep Fescue. The forb species observed were Western Yarrow and <br />Cicer Milkvetch. Small shrub saplings of Big Sagebrush and Rubber Rabbitbrush were observed on this parcel. <br />Cheatgrass and either Bull or Musk thistle was observed on this parcel. Dense patches of thisle were not observed <br />and the cheatgrass did not appear to be hindering the development of the desired vegetation. Overall, it appears <br />vegetation has established in this area to support the post mine land use. This parcel is the lower half of the face of <br />Horse Gulch Fill. It appears small rills has formed on this parcel but have since stabilized with dense vegetation <br />cover. Gullies, bulges and cracks were not observed. <br />The 8.6 acre portion of Parcel Z -A -07 was observed. The topsoil depth for the Z -A -07 parcels was evaluated <br />during the October 24, 2007 Division inspection, the average topsoil depth observed for this parcel was 11.3 <br />inches. The dominant perennial grass species observed was various Wheatgrasses and Basin Wildrye. The forb <br />species Sphaeralcea coccinea, Scarlet Globemallow was observed. Musk thistle was observed in small patches <br />within this parcel and small rosettes were observed. Trapper will need to continue to monitor this area and <br />conduct weed control measures in the future. The Division observed several species of shrubs such as Big <br />sagebursh and Atriplex canescens; Fourwing Saltbush within this parcel. Overall, it appears vegetation has <br />established in this area to support the post mine land use. It appears small rills had formed on this parcel but have <br />since stabilized with vegetation cover. Gullies and other erosion features were not observed. <br />The 2.3 acre and 1.2 acre portion of parcel Z -A -10 was observed. The Division evaluated topsoil replacement <br />depth on these parcels during the August 15, 2013 inspection. The average topsoil depth found was 13.75 inches. <br />The dominant species observed appeared to Cheatgrass and Sisymbrium altissimum; Tumble mustard on this <br />parcel. Sparse perennial grasses such as Wheatgrass, Sheep Fescue and Basin Wildrye were observed. Canada <br />thistle was also observed on 2.3 acre parcel. The Division is currently evaluating if these two parcels are eligible <br />for bond release. Rills and gullies were not observed on this parcel. <br />The 4.2 acre portion of parcel Z -A -08 was observed. The Division evaluated topsoil replacement depth on the Z- <br />A-08 parcel during the April 20, 2010 inspection. It appears the topsoil was observed to have been replaced at a <br />depth of greater than 10 inches. Dense grass has established on this parcel. The dominant perennial grasses <br />observed were Wheatgrasses, Sheep Fescue and Basin Wildrye. The forb Cicer Milkvetch was observed. Either <br />Musk or Bull Thistle was observed as small rosettes on this parcel.
