<br />• <br />• <br />2.6.3 Section 16 <br />Tables 8 and 9 exhibit the average cover and composition of vegetation found on the four Section <br />16 units evaluated in 2003. Un"itr 516009 and 516010 (7 growing seasons) have progressed well toward <br />satisfaction of required bond release criteria with the exception of woody plant density. Perennial cover <br />{58.6% and 54.2%) and production (2,900 and 2,450 pounds per acre) should easily pass comparisons <br />with the reference areas, while the present diversity of perennial grasses and forts (7 perennial grasses <br />and i perennial fort) in 516010 meets the standard of 3 perennial grasses and 1 perennial fort with <br />between 3% and 50% relative cover. Unit 516009 presently has no perennial forts with at least 3% <br />relative cover and therefore, does not meet the standard. However, one perennial fort, cicer milkvetch, <br />presently exhibits 2.1% relative cover and is likely to eclipse the 3% mark in the future. Woody plant <br />densities in 516009 and 516010 are low at 152 and 265 woody plants per acre, respectively, which are <br />far below the present standard of 90% of 1,000 woody stems per acre. See Appendix AA -Section 7.4 <br />for a discussion on options and recommendations with regard to woody plant density. Present levels of <br />annual brumes are low in these units and treatment is not presently recommended. <br />Units 516016 and 516017 are exhibiting very positive resultr after four growing seasons. Perennial <br />vegetation appears to be healthy and presently exhibits 41.3% average ground cover in 516016 and <br />29.5% in S17017. Although annual bromes currently represent 17% cover in 516017, it would be <br />prudent to monitor these patches to gauge if they are expanding or shrinking. If monitoring reveals they <br />are expanding, use of the herbicide Oust or Plateau is recommended. Woody plant density is excellent in <br />516016 with 737 woody plants per acre, while 516017 exhibits onty 178 woody stems per acre. 516016 <br />will quite possibly meet the woody plant standard of 1,000 plants per acre in the future if the present <br />population continues to expand. <br />I(ennecotl Enorpy Co. / Colowyo Mitre <br />Page 73 <br />Revegetatlon Monttoring -2003 <br />
