Lyons Quarry ��� <br /> 112d Reclamation Permit Operations <br /> Technical Revision <br /> Ecologist David Hirt. This seed mix incorporates species that have performed well. Table 3 shows <br /> the native seed mix recommended for 5,500 to 7,000 feet elevation (reclaimed areas at the site <br /> range in elevation from 5,500 to 5,820 feet). The listed quantities and application rates are shown in <br /> pounds of pure live seed per acre (#PLS/Acre). Assumed application rates have been doubled to <br /> account for broadcast seeding. The seeding is anticipated to be completed from March -April 15, <br /> 2022. If any areas must be prepared in the summer, fall, or winter, then the topsoil will be mulched at <br /> that time and seeded the following spring. <br /> Table 3 — Native Seed Mixes 5,500 Feet to 7,000 Feet Elevation <br /> Common Name Species Name Variety <br /> Canada Wildrye Elymus canadensis Mandan 12 3.64 <br /> Blue Grama Bouteloua gracilis Native,Alma, or Hachita 14 0.59 T <br /> Slender Wheatgrass Elymus trachycaulus San Luis or First Strike 10 2.19 <br /> Squirrel Tail Elymus elymoides Pueblo 12 2.18 <br /> Thickspike Wheatgrass Elymus trachycaulus Critana 10 2.26 <br /> Sandberg Bluegrass Poa secunda Colorado Plateau 5 0.38 <br /> Switchgrass Panicum virgatum Blackwell or Nebraska 28 or 9 0.81 <br /> BOCO <br /> Green Needlegrass Stipa viridula Lodorm or Native 8 1.54 <br /> Fringed Sage Artemesia frigida VNS 4 0.03 <br /> Hairy Golden Aster Heterotheca viliosa VNS 5 0.20 <br /> Rocky Mtn.

A soil <br /> analysis will be performed as part of the Test Plots to determine the fertilizer needs. Immediately <br /> following the seeding and fertilizing, the area will be lightly scarified and mulched using various <br /> application processes, based on the final grade, soil conditions, and equipment access. These may <br /> include: <br /> • Long-stemmed native prairie hay, (4000 lbs./acre) and a tackifier emulsion (150 gal/acre <br /> hydro mulched. It is assumed that hydro mulch will be applied to slopes 2H:1V or steeper <br /> (unless prohibited by access or topography) (See Exhibit F— Reclamation Plan). Based on <br /> the revised grading plan, at least 11.3 acres are in this slope range. <br /> March 2021 1 20 <br />
