2005 Edna Mine Vegetation Sampling Report <br />• Additionally, two reference areas (snowberry/sage vegetation community and oak <br />mountain shrub vegetation community) were sampled for cover and production to <br />establish vegetation bond release standards. The snowberry/sage vegetation community <br />represents 83% of the pre-mine disturbance. The oak mountain shrub vegetation <br />community represents 17% of the pre-mine disturbance. Appropriate vegetation <br />parameters for each reclaimed unit were compared to the reference areas' weighted <br />mean herbaceous cover and production values. <br />7.3. Summarized Results <br /> <br />• <br />Results of the vegetation sampling in 2005 are summarized below in Table 1-2. All <br />sampled units met or exceeded the appropriate Bonded Reclaimed Areas & Vegetation <br />Performance Standards. It should be noted that data from 'West Ridge BRU: No- <br />Topsoil" and "Moffat BRU: No-Topsoil" were combined for sampling purposes as <br />detailed in the sampling plan. <br />Table 1-2: 2005 Edna Mine Veqetation Results Summarv <br />Sampling West Ridge Moffat BRU: West Ridge BRU <br />Parameter BRU: Topsoiled' Topsoiled' & Moffat BRU: <br /> No-Topsoil <br />Cover Standard 24.1 24.1 47.0 <br />(oho) 2005 Mean 55.1 52.9 41.6 <br /> Standard Passed YES YES YES <br />Production Standard 80.2 80.2 n/a <br />(g/m) 2005 Mean 126.5 160.9 n/a <br /> Standard Passed YES YES n/a <br />Shrub Density Standard n/a 1000 n/a <br />(stems/ac) 2005 Mean n/a 2119 n/a <br /> Standard Passed n/a YES n/a <br /> Min 5 Species Min 5 Species 90% graminoids3 <br /> Standard between 3 & 40% between 3 & 40% 5% forbs3 <br /> Re[ Importance Rel.
