• 2.4.3 S36O16 <br />516016 is comprised of 23.9 aces of gently sloping revegetation that has a predominately <br />southeasterly aspect. This unit was seeded in 1999 and therefore, has undergone four growing seasons <br />prior to sampling in 2003. A total of 41 plant taxa were observed in the unit (see Table 19). <br />Ground cover (Fgure 16) wnsisted of 54.6% live vegetation, 0.7% rock, 0.1% standing dead, <br />25.1% litter, and bare soil exposure of 19.5%. Perennial cover across the unit averaged 41.3% with <br />annual and biennial cover averaging 13.3%. The dominant taxa were Kentucky bluegrass, field <br />pennycress, slender wheatgrass, smooth brome, and Japanese brome with 16.490, 5.5%, 4.6%, 3.7%, <br />and 3.2% average Dover, respectively. Woody plant density was determined from 15 belt transeds and <br />totaled 737 young and mature stems per acre (Table 2) with big sagebrush the dominant woody plant. <br />With regard to diversity, S16016 exhibited 6 perennial grasses and 1 perennial fort with between 3% and <br />50% relative cover. <br />Unit 516016 currently passes the bond release diversity standard of 3 perennial grasses and i <br />perennial fort with between 3% and 50% relative cover. This unit should also readily pass both the <br />• Dover and production bond release wmparisons to the reference areas. This unit does not presentty <br />meet the woody plant standard of 90% of 1000 stems per acre, but the likelihood is good that it will <br />meet this standard in the foreseeable future. See Appendix AA -Section 7.4 for a discussion on options <br />and recommendations with regard to woody plant density. Noxious weeds appear to be controlled in this <br />unit. Although annual bromes currently represent only 5.5% cover, these populations should be <br />monitored to gauge if they are expanding or shrinking. If monitoring reveals they are expanding, use of <br />the herbiade Oust or Plateau is recommended. <br />At present, S16016 is progressing very well toward satisfaction of all Phase III success criteria. This <br />unit is also a good example of an improved pasture grassland community that would contribute to the <br />local system as foraging habitat for wildlife (especially elk), as well as provide a variety of management <br />opportunities for livestock grazing. <br />• <br />Kennernn Energy Co. ~ Coloeryo Nine Page 56 RevegeTetlon MonNorirrg -2003 <br />
