1 <br />1 <br /> 3.2.1 Meadow <br />' The Meadow vegetation type occurred in the bottom of Delagua <br /> Canyon and extended partially uphill where it interphases with the <br /> Pinyon-Juniper Woodland Complex. The soils in the canyon bottom were <br />' generally deep and alluvial in origin. Total affected area of this <br /> vegetation type was only about 8 acres (Table 21. The Meadow vegeta- <br /> tion type contained numerous disturbances, including old coal spoils <br /> and homesites. This vegetation type was dominated by numerous species <br />' of grasses, predominantly western wheatgrass IAganpyava wn<#hlil. <br />' Cover <br /> Total absolute vegetation cover in the Meadow vegetation <br /> type averaged 72.2 percent,(' Bare soil was only 3.8 percent while fitter <br /> cover was high 123.2 percent). Rock cover was very low, with only <br /> 0.8 percent. Absolute cover by lifeform was as follows: perennial <br /> graminoids--65.8 percent, perennial forbs--2.7 percent, annual forbs-- <br /> 1.9 percent, annual graminoids--0.9 percent, shrubs and subshrubs--0.8 <br />' percent, and succulents--0.1 percent (Table 31. <br />' Perennial graminoids contributed over 90 percent of the <br />relative vegetation cover. Western wheatgrass was dominant with 32.1' <br /> percent absolute cover while green needlegrass IS,Lipa vt~.idu.lal and <br /> Aggasiz bluegrass l%va ago~~i~v~+.iial were subdominants with 13.0 and <br />' 11.3 percent cover, respectively. Other common species were sleepy <br /> grass (St<pv aobu~tal with 3.9 percent, sand dropseed 15pv~oGolua <br /> clr~ptnndnua) with 3.3 percent, and blue grama 1/3oufe.louo gaacili~l <br /> with 1.3 percent. Blue grama was more common on upland areas with <br />' drier and shallower soils. Less common graminoids included needle-and- <br /> thread fStipo comafa), elk sedge ICn22x ge~e2i1, and red three awn <br /> (A.¢iatidv Aoagi~elal. See Table 3. <br />t <br /> Perennial forb cover was lav, with only 4.1 percent relative <br /> cover. The more common species included field bindweed lCvavu.lvu.lua <br />' navennial, timber milkvetch (A~.t2aga.lua mi~e~), Louisiana sage <br /> (A.¢lemiaiv (udvvicianal, hairy goldenaster (H¢te2vthecn v1.Llow 1, and <br /> scarlet globemallow (Sphaem.lceo eoeeirzevl. <br /> Annual forb cover was low, but consisted entirety of prickly <br /> lettuce ILoctuco ~e~civ.lo) and yellow sweetclover (Melt.(vtu~ o~~iuav.(i~l. <br />' Annual graminoids accounted for little cover. Species <br /> present were Japanese hrome I/3.zvmu~ aapvrz<cuol and cheatgrass Illavmu~ <br /> tec.to.eum 1 . <br />' Shrubs and subshrubs provided only 1.1 percent of the <br /> relative cover. Only rubber rabbitbrush ICh~~ev.thomnu~ nnu~ev~u~l <br /> and broom snakeweed lsu.tie,22e~io 4ono#h.2ne) contributed to cover. <br />' See Table 3 for additional minor plant species. <br />1 <br />-7 <br />
