The appearance of revegetated areas varied based on seeding date, degree of <br />development and other factors, but atl revegetated areas were visually dominated by <br />graminoid species. Undisturbed areas adjacent to the revegetated areas were dominated <br />by native riparian vegetation communities characteristic of ephemeral drainages in the <br />Colorado Plateau. Specific sampling information for Area 2 is contained in Table 4. <br />1 <br />Five lifeform classes were represented within Area 2; graminoids, forts, shrubs, <br />suffrutescent shrubs, and cryptogams. Total vegetation cover of the Area 2 was <br />21.88% (excluding cryptogams). Cryptogams accounted for O.19'o cover, litter 18.4° <br />cover, rock 3.5 % cover, and bare areas 56.1 ~O cover. Based on cover sampling, <br />graminoids represented 10.9% mean wver, forts accounted for 9.596 mean cover, and <br />shrubs and suffrutescent shrubs 1.596 mean cover. <br />The co-dominant vascular plant species were the graminoids Bromus tectorum <br />(Cheatgrass) at 3.5`% mean cover (16.0% relative cover) and ~gropyron cristatum <br />(Crested Wheatgrass) at 3.496 mean cover (15.496 relative cover). Subdominant <br />species included .~gropyron trachycaulum (Slender Wheatgrass) at 0.88 % mean cover <br />(4.0% relative cover) and ~ropyron mtermedium (Intermediate Wheatgrass) at 0.7596 <br />mean cover (3.490 relative cover). Bromus inermis (Smooth Brome) was close to the <br />3°/o relative cover level at 0.6396 mean cover and 2.9°k relative cover. The remaining <br />graminoid species comprised between 0.196 and 0.5% mean cover. With the exception <br />of Bromus tectorum, all of the dominant and subdominant grasses are perennial cool- <br />season reclamation grasses. Several perennial grass species native to the area were <br />encountered in Area 2. These included Agropyron smithii (Western Wheatgrsss), <br />,~gropyron trirnphorum (Pubescent Wheatgrass), Bouteloua gracilis (Blue grama), <br />FJymus junceus (Russian Wildrye), Hilaria jamesii (Galleta), and Oryznpsis hymenoides <br />(Indian Ricegrass). <br />The dominant forb species in Area 2 was Medicago saliva (Alfalfa) at 4.596 mean <br />cover (20.6'% relative cover). Additional dominant species (representing more than 3% <br />relative cover) were Centaurea repens (Russian Knapweed) at 1.390 mean cover (5.79'0 <br />relative cover), Conwvulus ar~ensis (Field Bindweed) at 1.0% mean cover (4.690 <br />relative cover), and Erodium circutarium (Filaree) at 0.75% mean cover (3.496 relative <br />cover). Kochia scaparia (Kochia) and Melilotus alba (White Sweetclover) each <br />represented 0.6% mean cover (2.99'o relative cover), approaching the other dominant <br />species. 1Nedicago sativa, the dominant forb represents a leguminous perennial <br />moderately long-lived reclamation, pasture, and range species. Remaining dominant <br />species represent annual species or noxious species characteristic of disturbed areas. <br />Noteworthy among the lesser species was Sphaeralcea coccinea, Copper Globemallow, <br />a native of the area which was seeded in the reclamation seed mix for Area 2. <br />The dominant woody plant species in Area 2 was Atriplex canescens (Four Wing <br />' Saltbush) representing 0.8% mean cover and 3.4% relative cover. Three other shrubs <br />and subshrubs were encountered in Area 2. <br />I <br />I 10 <br />
