~ Vegetation Cover <br />,• <br />Total vegetation cover of the 1985 Reclamation Area was 21.00%. Based on cover <br />sampling, graminoids represented 20.00% mean cover (95.35% relative cover), fortis <br />accounted for 0.80% mean cover (3.72% relative cover), and shrubs 0.20% mean <br />cover (0.93% relative cove). <br />_ _ The co-dominant plant species were CalamovilFa longi(olia (prairie sandreed) with <br />6.40% mean cover and 31.16% relative cover and Bromus marginatus (mountain <br />brome) at 6.20% mean cover (28.84% relative cover). Sub-dominant species included <br />_ Agropyron cristatum (crested wheatgrass) with 2.40% mean cover and 11.16% relative <br />cover, Sporobolus cryptandrus (sand dropseed) with 1.6% mean cover and 7.44% <br />relative cover. Additional significant components included; Andropogon hallii (sand <br />• bluestem) with 1.00% mean cover and 5.12% relative cover, Bouteloua gracilis (blue <br />grama) at 1.00% mean cover and 5.12% relative cover, and Bromus tectorum <br />(cheatgrass) with 1.00% mean cover and 4.65% relative cover. <br />Vegetative litter (prior years growth, dead wood, and other biologic organic material) <br />comprised 52.80% ground cover within the 1985 Reclamation Area. Bare soil <br />comprised 26.20% of the ground cover encountered in the 1985 Reclamation Area. <br />Herbaceous Production <br />Total herbaceous production on the 1985 Reclamation Area was 87.33 g/m2 (778.44 <br />16/ac). Perennial grasses dominated herbaceous production, comprising 84.45 g/m2 <br />(754.91 ]b/ac) or 97 percent of total herbaceous production. Annual grasses <br />contributed 0.24 g/m (2.14 lb/ac), or 0.3 percent to herbaceous production in this <br />area. No perennial (orbs were present in the production sampling in this area. Annual <br />fortis accounted for 2.64 g/m2 (23.53 16/ac) of the reference area herbaceous <br />production. Annual fortis provided 3 percent of the total herbaceous production in this <br />area. <br />Species Diversity <br />I. <br />l <br />Within the 1985 Reclamation Area three lifeforms were represented. The total number <br />of species encountered during cover sampling was eleven (I 1). They included seven <br />species of perennial grasses, one annual grass species, one annual forb, one perennial <br />forb, and one woody shrub species. Of the species encountered on the 1985 <br />Reclamation Area, eight (8) were native and three were introduced. Perennial species <br />outnumbered annual species by nine to two. Seasonality of 1985 Reclamation Area <br />species was split between cool season, warm season and evergreen species. Four <br />graminoids were cool season species and four were warm season species. All forb <br />species were identified as cool season. The shrub species was evergreen. <br />-~- <br />
