Overall within the 1995 reclamation azeas, Calamovilfa longifolia and Sporobolus <br />cryptandrus (sand dropseed) were co-dominant, with both contributing 3.00 percent mean <br />• cover and 12.14 percent relative cover. Ten additional species contributed significantly to <br />cover, including Bouteloua gracilis with 2.20 percent mean and 11.43 percent relative <br />cover, Agropyron cristatum (crested wheatgrass) providing 2.40 percent mean cover <br />(9.29% relative cover), Bouteloua curtipendula (sideoats grams) with 1.60 and 8.57 <br />percent mean and relative cover respectively, Panicum virgatum (switchgrass) <br />contnbuting 1.20 percent mean cover (7.14°(o relative), Schizachyrium scoparium (little <br />bluestem) with 1.40 percent mean and 6.43 percent relative, Agropyron dasystachyum <br />(thicksp>7ce wheatgrass) and Bromus marginatus (mountain brome) both with 1.60 percent <br />mean cover and 5.71 percent relative cover, Agropyron smithii (western wheatgrass) <br />contributing 1.40 percent mean and 5.00 percent relative cover, and Andropogon hallii <br />and Kochia scoparia each contributing 1.20 and 1.00 percent mean cover respectively, <br />with 4.29 percent relative cover. <br />Vegetative litter (prior yeazs growth, dead wood, and other biologic organic material) <br />comprised 52.60 percent ground cover overall within the 1995 reclamation azeas. Baze <br />soil comprised 24.20 percent of the ground cover. No rock or cryptogams were <br />encountered during the cover sampling in the 1995 reclamation azeas. <br />Herbaceous Production <br />Overall total herbaceous production within the 1995 reclamation azeas was 52.13 g/m2 <br />(465 lb/ac). Perennial grasses contributed the most to herbaceous production, 46.45 g/tnz <br />(414 Ib/ac), accounting for 89.1 percent of total herbaceous production. Perennial forbs <br />• contributed the second highest productions with 4.17 g/m2 (37 lb/ac), which was eight <br />percent of the total mean herbaceous production Biennial forbs contributed 1.49 g/m2 <br />(13 Ib/ac) or 2.8 percent of total herbaceous production. Annual grasses contributed the <br />least to annual herbaceous production in this azea this yeaz (0.01 g/tttz or <l lb/ac). <br />Annual forbs did not contribute to total herbaceous production this season. <br />Species Composition <br />Cover sampling identified three lifeforms and 18 species within the 1995 reclamation <br />azeas. The lifeforms included twelve species of perennial grass, one annual grass, one <br />perennial forb, three annual forbs, and one woody shrub. Of the species encountered on <br />the 1995 reclamation azeas, thirteen were native and five were introduced. Perennial <br />species outnumbered annual species by fourteen to four. Warm and cool season species <br />contributed neazly equally to the seasonality of the 1995 reclamation azeas. Warm season <br />graminoid species accounted for seven species and cool season species included six <br />species. Three forb species were identified as cool season and one was warm season. The <br />shrub was deciduous. <br />The 1995 reclamation azeas had twelve species contributing greater than three percent <br />relative cover this yeaz. These species included eleven perennial grasses and one annual <br />I • <br />Coore Energy Company Page 8 <br />2002 Revegetation Monitoring Report <br />
