areas sampled during 2020 is given in Table 1.2-4. A summary of individual transects, reclaimed parcels <br />and reclaimed blocks is presented in Appendix 2. <br />Table 1.2-1 indicates that the Phase II cover standard was achieved for the sampled block. The <br />reclaimed block summary in Appendix 2 further indicates that plant cover sample adequacy was easily <br />achieved for the areas sampled. <br />Shrub density data is included in Tables 1.2-1 and 1.2-3 for interest only, as shrub density is not a Phase II <br />bond release requirement. These data also serve to help demonstrate that plant diversity is being <br />achieved on all Range Sites A and B bond release blocks. <br />Table 1.2-2 breaks out sampling results at a plant life form and plant species level for cover. This table <br />gives a good indication of the overall performance of individual grass and forb species in reclaimed <br />vegetation communities. Dominant grass species include a variety of Wheatgrasses, Kentucky <br />Bluegrass, Sheep Fescue, Mountain Brome and Great Basin Wildrye. Other grasses that appear to be <br />well established and contributing to plant community diversity are Green Needlegrass and Smooth Brome. <br />Dominant forb species include Western Yarrow, Lewis Flax and Alfalfa. Other established forbs that <br />contributed to diversity are Cicer Milkvetch and Penstemon spp. Detection of several perennial noxious <br />weeds (Whitetop, Canada Thistle and Hound's Tongue) at low levels indicates a need to continue weed <br />control efforts, which is occurring on an annual basis. Cheatgrass was also present at relatively low level <br />in the proposed bond release area. <br />Stem density results in Table 1.2-3 demonstrate that five shrub species, Big Sagebrush, Silver Sagebrush, <br />Rubber Rabbitbrush, Bitterbrush and Snowberry make up the vast majority of the shrubs counted on belt <br />transects. Fourwing Saltbush, Mountain Snowberry and Green Rabbitbrush are also well established in <br />lower numbers across the reclaimed lands included in this bond release application. <br />Relative cover evaluation of perennial plant species and life forms for block and parcel summaries in <br />Appendix 2 conclusively demonstrates that established plant species are exhibiting seasonality and <br />species composition supportive of the post -mining land use. <br />G <br />
