2006 Edna Mine Vegetation Sampling Report <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 Vegetation Results <br />Sampling West Ridge <br />Parameter Topsoiled BRU <br /> Standard 24.1 <br />Cover 2006 Mean 40.0 <br />(%) Standard Passed YF '-- ,. <br /> Standard 41\7- <br />Production <br />Production <br />2 <br />2006 Mean <br />149.1 a, <br />(g/m <br />) Standard Passed ` YES <br /> Mil- SpeciE <br /> Standard bet, 4G: o <br /> l: G»po,._,ce <br />Diversity <br />Top-soiled' <br />y-_ <br />39.7 <br />:%185.2 <br />YES <br />Min 5 Species <br />between 3 & 40% <br />Rel.
