relative cover data will be ranked to determine the importance of the species in the <br />revegetated azea. <br />Woody Plant Density <br />Woody plant density will be evaluated through use of belt transects. Two by twenty-five <br />meter transects (50 square meters in azea) will be located adjacent to the cover trarisects. <br />If necessary, additional plots will be randomly located. Woody plants rooted within the <br />transect will be counted by species. Woody plant density is not proposed to be sampled in <br />the existing reference areas, as density values have already been established for these <br />areas. <br />Sample Adequacy <br />The proposed disturbed area and reference azea(s) will be sampled until sample adequacy <br />is reached for each parameter, or a maximum of fifty samples is collected for a given <br />parameter in each area. A minimum of fifteen samples (15) for each parameter will be <br />collected in the proposed disturbed azea, and a minimum of ten (10) samples for each <br />parameter will be collected in any reference area(s) sampled. A maximum of fifty (50) <br />samples for each parameter will be collected within the proposed disturbed area and any <br />reference area(s) sampled. For the purposes of evaluating vaziability of the reference and <br />proposed disturbed azea, sample adequacy will be calculated for each parameter. The <br />following formula will be used for these calculations: <br />(t)Z (s)2 <br />mm ------ <br />(d Xbar)z <br />where: n~ =minimum sample size <br />t =the Student's t distribution value at the 90% confidence level <br />s =sample standazd deviation <br />s2= sample variance <br />d =percent acceptable deviation from the mean (] 0%j <br />X~ =sample mean <br />Summary Report <br />Savage and Savage will prepare a technical report addressing vegetation condition of the <br />any reference area sampled and the proposed disturbed area, the results of the 1999 <br />vegetation sampling, analysis of the physical chazacter, and developmental trends of the <br />vegetation. We will prepare a statistical comparison of the reference area(s) and proposed <br />disturbed area. Pertinent maps, figures, and tables will be prepared to graphically illustrate <br />results, conclusions, and any trends. <br />-4- <br />
