4-51 <br /> present within the quadrats and it was 4 m high and had a DBH <br />• of 12 cm. See Table 9.5-205. <br />4.5.2.2.6 Agricultural <br />Numerous small agricultural areas occur along East Salt Creek <br />in what was once Greasewood Shrubland habitat. These fields <br />today are deteriorated haylands. Alfalfa Medicago sativa, <br />native bluegrass Poa pratensis, and alta fescue Festuca arun- <br />dinacea, an introduced grass, are the dominant plants. Invading <br />species present in the Hayfields include: cheatgrass, meadow <br />baYley Hordeum brachyantherum,tdll wheatgrass Agropyron elongatum, <br />slender wheatgrass Agroypron trachycaulum, Pacific aster Aster <br />chilensis, siskiyou aster Aster hesperus, Chicory Chicorium <br />intybus, dandelion Taraxacum officinaZe,cocklebur Xanthium sp., <br />Russian thistle SaZsola iberica, dodder Grammica sp., and <br />bindweed Convolvulus arvensis. <br />Herbaceous production within the unirrigated hayfield, based <br />• upon estimates of the rancher farming the area, is approximately <br />2,000 lbs/ac. <br />4.5.2.3 Species Diversity <br />Table 4.5-215 identifies, by major life form for each of the <br />quantitatively sampled vegetation types, all species having <br />a relative cover greater than 3 percent. Thus, the Greasewood <br />Shrubland affected area has a species diversity of 4 composed <br />of two shrubs, one annual grass, and one annual forb. The <br />reference area for this vegetation type has a species diversity <br />of 6 composed of two shrubs, one perennial grass, one annual <br />grass, and two annual forbs. <br />The Shadscale cheatgrass vegetation type has a species diversity <br />of 4 composed of three shrubs and one annual grass. The species <br />diversity of the Shadscale Wildrye area is four. The composition <br />includes one tree, one shrub, and two perennial grasses. <br /> <br />
