<br />production. Annual grasses contributed 1.5 g/m2 (13.4 lb/ac), or 0.3 percent to <br />herbaceous production in this area. Perennial forbs were significantly present in the <br />' production sampling in this area and contributed 70.6 g/m2 (629.3 lb/ac), accounting <br />for 14.2 percent of the total mean herbaceous production. Annual forbs accounted for <br />24.6 g/m2 (219.3 Ib/ac) and 4.9 percent of total herbaceous production. Forbs <br />' represented over 19 percent of the herbaceous production in the 1987 reclamation area <br />in 1995. <br />' Species Diversity <br />' Within the 1987 Reclamation Area four lifeforms were represented; graminoids, forbs, <br />succulents, and woody shrubs. The lifeforms included nine species of perennial grass, <br />eight annual forbs, one succulent, and one woody shrub. Of the species encountered <br />on the 1987 Reclamation Area, thirteen were native and six were introduced. Perennial <br />species outnumbered annual species by eleven to eight. Seasonality of 1987 <br />Reclamation Area species was split between cool season, warm season, evergreen, and <br />~, deciduous species. Graminoids were nearly evenly split, five were cool season, and <br />four were warm season species. With the exception of Helianthus annuus, all fort <br />species were identified as cool season. The succulent was evergreen and the shrub <br />' species was deciduous. <br />Six species (five grasses and one forb) represented greater than three percent relative <br />'' • cover. These species included Calamovilla /ongikilia (56.31%), Agropyron cristatum <br />(7.17%), 6rigeron be/lid~astrum (6.8390), Bromus margmatus (5.4640), Agropyron <br />~ dasystachyum (4.104'0), and Bouteloua gracilis (3.0796). <br />1 <br /> <br />1 <br /> <br /> <br />1 • <br />' -11- <br />
