site. Noxious weeds were the second most dominant plant life form, contributing 4.92 percent of the total plant cover and 17.60 percent of the total relative cover. Annuals and biennials contributed 1.24 percent of the total plant cover and 4.43 percent of the total relative cover. Native shrubs contributed 0.76 percent of the total plant cover and 2.72 percent of the total relative cover. Native perennial forbs contributed 0.32 percent of the total plant cover and 1.14 percent of the total relative cover found on this area. Russian Wildrye, a planted introduced perennial grass was the dominant plant species encountered, contributing 58.37 percent of the total relative plant cover found on this site. The other dominant plants encountered were: Storksbill, Russian Knapweed, Western Wheatgrass and Smooth Bromegrass which contributed 9.01, 6.29, 4.58 and 4.15 percent, respectively, of the total relative cover on this area. The locations of the 25 cover sampled in the NH1 Reclamation Predisturbance Area are shown on Map 2.04.10-1. The sample adequacy calculations in Table 2.04.10-2\, document that the number of samples required to describe this site at the 90 percent confidence interval was 14.3 transects. The results obtained from the June 2010 sampling of the Intensively Managed Irrigated Pasture are found in Appendix 2.04.10A, and the results obtained from the June 2011 sampling of this same property are found in Appendix 2.04. l OB. Application of the historical record approach as a revegetation success standard for this vegetation and land use type yields the following results: Average total plant cover in 2009 was 94.00 percent, in 2010 was 95.33 percent and in 2011 was 92.13 percent. The average total plant cover from the three monitoring periods was 93.82 percent. Ninety percent of this value equals 84.44 percent total plant cover. Thus, at the time of final bond release the total plant cover revegetation success standard for the Intensively Managed Irrigated Pasture type will be 84.44 percent total plant cover. Production The results obtained from the sampling of 50 production transects on this area are summarized in Table 2.04.10-4. The average total herbaceous forage production equaled 23.70 g/1/4 m2 or 845.0 pounds of air dry -dry forage per acre. Perennial grasses contributed 23.11 g/1/4 m2 or 97.47 percent of the herbaceous forage. Perennial forbs, contributed 0.60 g/1/4 m2 or 2.53 percent of the herbaceous forage production. The locations of the 50 production transects sampled on this site are shown on Map 2.04.10-1. The sample adequacy calculations in Table 2.04.10-2,, document that the number of samples required to describe this site at the 90 percent confidence interval was 60.4 transects.
