cover), (orbs accounted for 2.60 percent mean cover (10.42% relative cover), and a succulent accounted for 0.2 percent total and 1.39 percent relative cover. The dominant plant species was Calamovilfa longifolia (prairie sandreed) with 8.00 percent mean cover and 29.86 percent relative cover. Following CalamovilFa closely was Andropogon hallii with 5.60 percent mean cover and 24.31 percent relative cover. Additional significant species included Bromus marginatus, which accounted for 3.00 percent mean cover and 10.42 percent relative cover, Ambrosia psilostachya contributing 2.20 percent cover (9.03% relative cover), Sporobolus cryptandrus at 2.40 percent mean cover (8.33% relative cover), Bouteloua gracilis with 2.00 percent mean cover (7.64% relative cover), and Schirachyrium scoparium (little bluestem) providing 0.80 percent total cover and 4.86 percent relative cover. Vegetative litter (prior yeazs growth, dead wood, and other biologic organic material) comprised 60.80 percent ground cover within the 1986 Reclamation Area. Bare soil comprised 14.00 percent of the ground cover enwuntered in the 1986 Reclamation Area. No rock was encountered in the cover sampling of this area. Herbaceous Production Total herbaceous production in the 1986 Reclamation Area was the highest of all azeas sampled this year with 80.71 g/m2 (719.4 lb/ac). As with other azeas, perennial • grasses dominated herbaceous production, contributing 72.13 g/m2 (643.0 lb/ac) or 89.4 percent of total herbaceous production. Annual grasses did not contribute to herbaceous production in this area this year. Perennial forbs were present in the production sampling in this area and contributed 7.05 g/m2 (62.8 lb/ac), accounting for 8.7 percent of the total mean herbaceous production. Annual forbs accounted for 1.52 g/m (13.5 lb/ac) and 1.9 percent of total herbaceous production. Species Diversity Within the 1986 Reclamation Area three lifeforms were represented; graminoids, forbs, and succulents. The lifeforms included eight species of perennial grasses, one perennial and two annual forbs, and one evergreen succulent. Of the species encountered on the 1986 Reclamation Area, ten were native and two were introduced. Perennial species outnumbered annual species by ten to two. Seasonality of 1986 Reclamation Area species was split between cool season and warm season species. Two graminoids were cool season and six were wazm season species. All forb species were identified as cool season. The succulent was evergreen in habit. Of the species encountered, six perennial grasses, and one perennial forb each contributed greater than three percent relative cover. These species were: Calamovilfa longifolia (29.86%), Andropogon hallii (24.31%) Bromus marginatus (10.42%), • Ambrosia psi/ostachya (9.03%), Sporobo/us cryptandrus (8.33%), Bouteloua gracilis (7.64%), and Schizachyrium scoparium (4.86%). -9-
