<br /> <br />RESULTS ARID DISCUSSION <br />Vegetation cover, production and density means are discussed <br />for each separate reference area and its corresponding vegetation <br />type. Dominant species are selected for each type based on cover, <br />production and density means. These dominant species are discussed <br />in relation to their physical environment. <br />The Maxwell !line, including the grassland and pinyon-juniper <br />types will be discussed first. Table 1 shows the mean cover values <br />for the grassland reference area. 6outeloua racilis had a mean <br />cover value of 31.3", Artemisia frigida had a mean cover value of <br />( ~ 7.5~, Carex eleocharis had a mean cover value of 3.5%, and <br />Xanthocephaluin sarothrae had a mean cover value of 2.7". The remain- <br />ing grasses and fortis had mean cover values of 1.8~ and below. Total <br />mean cover for the grassland site v,as 52.3';. Bare ground accounted <br />for 33.5;, of sampled areas, litter accounted for 14.0'x, and rock <br />accounted for 0.2~. (Tables are found in Appendix B.) <br />Production means for the grassland type are given in Table 2. <br />6outeloua gracilis had a mean production value of 23.5 gms/int. <br />Artemisia frinida had a mean production vaiue of 8.1 oms/m2, <br />0 <br />",stranalus issour'ensis had a .'~e~r ;r-o:i,.c[ion value or 5.4 g~:~si~n`, <br />Xanthocephalu~^ sarothrae had a mean production value of 4.9 gms/m`, <br />and Carer, eleocharis had a mean production vai;,e of 3.7 gins/int. The <br />re~~,aining species had mean prcduction values of 1.5 gnis/nit and below. <br />L Total mean production for the grassland site ,~,as 52.5 gms/m2. <br />8 <br />u <br />
