2006 Edna Mine Vegetation Sampling Report <br /> <br />mine disturbance. The oak mountain shrub vegetation community represents 17% of the pre- <br />mine disturbance. Appropriate vegetation parameters for each reclaimed unit were compared to <br />the reference areas' weighted mean herbaceous cover and production values. <br />1.3. Summarized Results <br />Results of the vegetation sampling in 2006 are summarized below in Table 1-2. West Ridge <br />Topsoiled BRU and Moffat Topsoiled BRU met or exceeded the appropriate Bonded Reclaimed <br />Areas & Vegetation Performance Standards. However, West Ridge BRU: No-Topsoil and Moffat <br />BRU: No-Topsoil, which were combined for sampling purposes as detailed in the sampling plan, <br />did not meet the appropriate Bonded Reclaimed Areas & Vegetation Performance Standards. <br />The non-topsoiled areas exceeded the standard set by the reference areas, but these two areas <br />were held to a different performance standard of 47% vegetation cover. Shrub density exceeded <br />the Bonded Reclaimed Areas & Vegetation Performance Standards in 2005 and therefore it was <br />unnecessary to sample it again in 2006. <br />Table 1-2. 2006 Edna Mine Ve etation Results Summar <br /> West Ridge BRU <br />Sampling West Ridge <br />' Moffat BRU: <br />' <br />& Moffat BRU <br />Parameter Topsoiled BRU Topsoiled No-Topsoil'' <br /> Standard 24.1 24.1 47.0 <br />Covet 2006 Mean 40.0 39.7 30.5 <br />` <br />Standard Passed <br />YES <br />YES <br />NO <br />Standard 41.6 416 n/a <br />Production <br />/m2 2006 Mean <br />( 149.6 _ <br />185.2 _ n/a <br />g Standard Passed YES YES n/a <br /> <br />Standard Min 5 Species <br />between 3 & 40% Min 5 Species <br />between 3 & 40% 90% graminoids3 <br />5% (orbs' <br /> Rel.
