species contributed between 12 and 24 percent relative cover. These species included <br />Agropyron intermedium and Astragalus titer, as well as Chrysothamnus nauseosus <br />Agropyron smithii, and Artemisia tridentata. The lack of dominance by one or two <br />species (as represented by relafive cover) indicates a maturing of the plant community. <br />The relative contribution of the lifeforms in the community has changed between 2000 <br />and 2006. In, 2000, gtaminoids contributed 48.55 percent of the relative cover, forbs <br />33.45 percent, and shrubs 18.00 percent. In 2006, graminoids again contributed the <br />highest level of relative cover (41.45%), while shrubs overtook forbs in contributions <br />(34.19 and 24.35%, respectively). The relative cover contributions by the lifeforms in <br />2006 also reflect a maturation in the vegetation community as stand age leads to <br />competition between shrubs, forbs, and graminoids, as well as definition of <br />microenvironments and niche spaces for the lifeforms and individual species. <br />The contributions of individual species have changed between 2000 and 2006 as <br />illustrated in Figure 5. The relative cover contributions of Agropyron cristatum, <br />t Oryzopsis hymenoides, Astragalus titer, Artemesia frigida, and Atriplex confertifolia <br />have remained the same or close to the same over the six yeaz period. The relative cover <br />contributions of Agropyron intermedium, Poa ampla, Melilotus offrcinalis, and <br />' Penstemon strictus have significantly decreased between 2000 and 2006. Whether this is <br />related to succession in the vegetation community or precipitation regime is open to <br />further investigation, but the trend is notable. The above decreases in relative cover <br />' contributions by those noted species have been countered by increases in others, notably <br />Agropyron smithii, along-lived native cool season grass, the ubiquitous annual Bromus <br />tectorum, and the shrubs Artemesia tridentata and Chrysothamnus nauseosus, dominants <br />' of the adjacent native shrub communities. <br />5.0 CONCLUSION <br />The quantitative vegetative cover and species composition data indicate that the permittee <br />' has established a diverse, effective, and permanent vegetative cover of the same seasonal <br />variety as the original vegetation. The revegetated azea is capable of self-regeneration <br />' and plant succession. The data shows development of a stable, self-sustaining vegetation <br />community, with seasonality and diversity sufficient to demonstrate successful <br />reestablishment of vegetation on the reclaimed area. <br />Fastside Goal Comparry Fastside Mine Page 7 <br />2006 Vegetation Sampling Report <br />
