1 <br />Two grass species were encountered during cover sampling in the reference area. <br />' Bromus japonicas/tectorum dominated at 29.0% mean cover (80.4% relative cover). <br />fiilaria jamesii comprised 1.4% mean cover and 3.7% relative cover. <br />' Annual fort species were represented by siz species in this transect. Descurainia <br /> Sophia and Ceratocepha/a orthoceras each comprised 0.6% mean cover (1.6% relative <br />' cover). I~pidium montanum accounted for 0.4% mean cover (1.1 % relative), while <br />Chorispora tenella and Lappula redows&ii each represented 0.2% mean cover and 0.8% <br /> and 0.5% relative cover each. Sphaera/cea coccinea (Scarlet Globemallow) accounted <br />' for 0.2% mean cover and 0.5 % relative cover. t7puntia polyacantha (Prickly Pear) <br />represented the succulent component in this area with 0.2% mean cover and 0.5% <br /> relative cover. <br />' <br /> Atriplex confertifo/ia comprised 3.0% mean cover and 8.7% relative cover while <br /> Atriplex obovata (Obovate Saltbush) accounted for 0.2% mean cover and 0.5% relative <br />' cover. <br /> Herbaceous Production <br /> <br /> Sample adequacy for herbaceous production sampling was achieved after five <br /> herbaceous production quadrats were sampled. Total herbaceous production for the <br />z <br />' Reference Area was 98.22 g/m <br />(874.16 lblac). Total production value on the <br /> Reference Area was roughly at the mid-point of all areas sampled. Bromus <br /> japonicas/tectorum dominated production with 88.16 g/m2 and 89.8% of total <br />production. Four perennial grasses accounted for 4.72 g/m2 representing 4.8% of total <br /> production. Sisymbrium altissimum (Jim Hill Mustard) was the major contributor to <br /> annual forb production with 4.8 g/mz and 4.8% of total production. Herbaceous <br /> production sampling results for the Shadscale Shrubland Reference Area are presented <br /> in Table 28. <br /> i <br />i <br /> es D <br />Spec <br />versity <br /> Five lifeforms were represented on this treatment plot. Perennial and annual grasses <br /> were each represented by one species. Annual fortis were represented by five species, <br /> succulents had one species represented, and woody plants three species. Only three <br />' lifeforms had representatives accounting for greater than three percent relative cover; <br /> perennial grasses, annual grasses, and woody plants with one species each. <br />44 <br />
