.l because nearly all plants consisted of only one stem. Number and height <br />of living shoot sprouts from local traasplaat crowns were recorded. <br />Average crown diameters were estimated by measuring the longest distance <br />betveea living sprouts and then measuring the distance between living <br />- sprouts on a line perpendiculaz to the first measurement. <br />" 2.8 Data Aaalvsis <br />The five quadrat values for density and production for each treat- <br />went plot were summed to obtain a density or biomass value/.5 mz <br />(5 z .1 m2 quads). Quadrat cover values for each plot were sued and <br />divided by five to obtain as average cover value/plot. A consequence of <br />this procedure is that ao variance for quadrats is plots vas estimated. <br />Since there were no signifieaat statistical differences within treatment <br />replications (p < 0.05) statistical analyses of quadrats vithia treatment <br />plots were warranted. <br />Values for cover, density, sad biomass for. each replication within <br />each slope-aspect mulch-mixture treatment were entered into a standard <br />analysis of variance (AOV) program for statistical analyses. <br />,~ The statistical analyses were complicated by the fact that all <br />mulch-seeding methods are not present across all slopes, sad the fact <br />that controls are sot replicated. The analysis approach vas to compare <br />selected treatments that would yield information about the major experi- <br />.. mental questions being asked (effect of slope, aspect, seeding method <br />and mulch). Four separate AOV's were nm to compare different groups of <br />treatments. The analyses are outlined on Figures 2.8-1 and 2.8-2. <br />15 <br />
