Empire Eagle Mine Vegetation Final Bond Release Monitoring 2005-2006 <br />square meters in size (2 x 50 meters). Belt transects will begin at the designated <br />sample start point and will be oriented as previously described above. <br />In reclaimed areas where woody stem density is highly variable, mapping of <br />higher density woody stem sub-areas may be performed. This will allow <br />segregation of woody stem density samples into high and low density subsets for <br />bond release and statistical testing purposes. <br />Each full shrub or subshrub that is rooted within and whose crown emerges from <br />the ground within the belt transect will be recorded by plant species. Shrubs and <br />subshrubs with multiple stems from a specific crown will be recorded as one <br />plant. Density data will be reported by plant species, plant life form (i.e., shrub, <br />subshrub and tree) and total woody plant density in the monitoring report. <br />VEGETATION PARAMETER SAMPLE POPULATION ADEQUACY <br />Sample population statistics will be provided demonstrating that the sample <br />population is comprised of at least the minimum number of required samples and <br />that adequacy has been met, or the maximum sample size has been reached for <br />each vegetation parameter sampled. The standard population sample adequacy <br />formula will be used to determine when an adequate sample has been collected: <br />tZSZ <br />N~ _ (~u)Z <br />Where: <br />Nm;,, =the minimum number of sample points needed in a given vegetation <br />type <br />2 x; - ll , x.1 ~n <br />S =sample variance S - <br />n-1 <br />d =Precision (0.10 by regulation) <br />Habitat Management, Inc. <br />13 <br />sm2oos <br />1 <br />
