' ~~ <br />2. The Standard Deviation formula on page 2.04.-67 appears to be incorrect <br />~ as presented. Please clarify. <br />' Response: The formula for the standard deviation given in 2.04.10(4) <br />does not have a summation sign in the numerator.

The reference area locations and sample locations should be included <br />on the vegetation map. <br />Response: Map No. 7, Mine 3 Premine Vegetation, has been revised to show <br />the areas within each vegetation type which were sampled. (See Map No. 7a). <br />4. In the vegetation type tables (12, 13, 14, 15), is Composition (%) <br />' equivalent to Frequency (%)? <br />Response: Percent composition as shown in vegetation tables 12,13,14, <br />t 15 is generated from the percent cover data and is determined by dividing the <br />total cover into the percent cover of each species. Except for some rounding <br />error, the addition (100.3) of the percent composition column equals 100 and <br />is often referred to as the relative percent composition or the relative <br />' percent cover. Percent frequency (the relative number of plots in which a <br />species occurred) was not calculated for this study. <br />S. Does the narrative for the meadow hay cropland vegetation type correspond <br />to Map 1~7 Unit 021 Hay Cropland? <br />1 <br />Response: Map unit 021, hay cropland, is synonymous with meadow hay <br />cropland as used in the narrative. <br />1~ <br />-2 <br />L- <br />
