• 2.4.2 S16030 <br />516010 is comprised of 15.17 aces of gentle to moderatey sloping revegetation that has a <br />predominatey southeasterly aspect. This unit was seeded in 19% and therefore, has undergone seven <br />growing seasons prior to sampling in 2003. A total of 45 plant taxa, including Canada thistle, were <br />observed in the unit (see Table 19). Current annual production across the unit averaged 2,481 pounds <br />per acre in 2003 with perennial grasses the dominant category (see Table 1). Ground Dover (Fgure 15) <br />consisted of 59.7% live vegetation, 0.6% rods, 0.0% standing dead, 20.5% litter, and bare soil exposure <br />of 19.3%. Perennial cover across the unit averaged 54.2% with annual and biennial cover averaging only <br />5.6%. The dominant taxa were intermediate wheatgrass, thickspike wheatgrass, Kentucky bluegrass, <br />and cicer milkvetch (AStragalus craer) with 14.2%, 14.0%, 4.2%, and 3.7% average cover, respedivey. <br />Woody plant density was determined from 20 heft transects and totaled 265 young and mature stems per <br />acre (Table 2) with big sagebrush the dominant woody plant. With regard to diversity, 516010 exhibited <br />7 perennial grasses and 1 perennial fort with between 3% and 50% relative cover. <br />Unit S16010 currently passes the bond release diversity standard of 3 perennial grasses and 1 <br />perennial fort with between 3% and 50% relative cover. This unit should also readiy pass both the <br />• cover and production bond release comparisons to the reference areas. This unit does not presently <br />meet the woody plant standard of 90% of 1000 stems per aae and will probaby not meet this in the <br />foreseeable future. See Appendix AA -Section 7.4 for a discussion on options and recommendations with <br />regard to woody plant density. Noxious weeds and annual bromes appear to be controlled in this unit <br />although a few scattered individual Canada thistles were observed. <br />At present, 516010 is a good example of an improved pasture grassland community that would <br />contribute to the kxal system as foraging habitat for wildlife (espedaly elk), as v+eN as provide a variety <br />of management opportunities for livestock grazing. <br />• <br />icennecoo erergy Co. / Cdowyo rune Page 53 Revegetatlon MonttoAng -2003 <br />
