13 <br />(i) The juniper woodland mix contains three introduced species that aze not necessary for <br />site stabilization or land use needs; tall wheatgrass, Russian wildrye, and prostrate <br />summer cypress. We recommend replacement of tall wheatgrass with the native slender <br />wheatgrass (Agropyron trachycaulum), and replacement of Russian wildrye with the <br />native Salina wildrye (Elymus salinus). Inclusion of bluebunch wheatgrass (Agropyron <br />spicatum) in this mix should also be considered. Addition of antelope bitterbrush <br />(Purshia tridentata) at a corresponding PLS seeds per squaze foot rate is recommended <br />to offset removal of the prostrate Kochia. <br />(ii) We do not consider planting of the three tree species to be necessary in the juniper <br />woodland disturbances, given the limited acreage of disturbance, and the uncertainties <br />of establishment of these species. Reclamation directed to ashrub/grass community will <br />satisfactorily address postmine Iand use needs. <br />(iii) The shadscale shrubland mix contains three introduced species that are not necessary <br />for site stabilization or land use needs; tall wheatgrass, Russian wildrye, and prostrate <br />summer cypress. We recommend replacement of tall wheatgrass with the native slender <br />wheatgrass (Agropyron trachycaulum), replacement of Russian wildrye with the native <br />Salina wildrye (Elymus salinus), and a corresponding increase in the seeding rate for <br />rubber rabbitbrush to offset removal of the prostrate Kochia. Also, two of the shrub <br />species aze not well adapted to the shadscale habitat, and could be deleted from the mix <br />(Utah serviceberry and true mountain mahogany). <br />(iv) The greasewood shrubland seedmix contains three introduced species that aze not <br />necessary for site stabilization or land use needs; tall wheatgrass, Russian wildrye, and <br />prostrate summer cypress. These species should be removed from the mix. Several <br />shrub species in the mix are not well adapted to the community type, and should be <br />deleted from the mix (Utah serviceberry, shadscale saltbush, true mountain mahogany, <br />and skunkbush). Consideration should be given to increasing the seeding rate of the <br />remaining species to offset the loss of the non-adapted species. Consideration should <br />also be given to inclusion of black greasewood (Sarcobatus vermiculatus) to this <br />seedmix at a relatively low rate. Greasewood is the dominant native shrub in this <br />community, is well adapted to the climatic, hydrologic, and soil conditions, and does <br />provide habitat for a variety of wildlife species. If greasewood is added to the mix, the <br />rate for fourwing saltbush should reduced by a corresponding amount. <br />11. Section 3.5 of the text, on pages 3-18 and 3-19 address Final Hydrologic Restoration , <br />The context of much of the narrative on page 3-19 (the first two pazagraphs) is unclear. <br />There is discussion of placement of a concrete slab within a trench beneath the <br />channel .The channel or channels to which this technique would be applied is not cleaz, <br />nor is the frequency of such slab installations specified. Please provide additional <br />detail for clarification. <br />13 <br />
