•~ Analyses in Figure 4 are iateaded to show aspect, mixture, and <br />mulch relationships on the same slope. Drill-strav is included here <br />• because it occurs on both aspects of 4:1 slopes, but is should be recog- <br />sized that straw plots are seeded at a lower rate. <br />Analysis in Figure 5 vas made because excelsior mulch sad control <br />treatments vere the_only treatments that occurred on ail slopes and <br />north and south aspects. West and east slopes were not analyzed in <br />order to reduce the complexity sad because of iasufficieat replication. <br />Excelsior Mulch <br />• Level (topsoil) Level (no topsoil) <br />~ mesic zerie mesie uric <br />` This aaalysia va- made to compare the effect of ao topsoil on level <br />1~ plots versus topsoiled level and k:1 plots. <br />Differences betveen treatment +~~~*+~ vere compared by the best sig- <br />aifieaat difference method (LSD) (Snedecor and Cochran 1967). LSD <br />values for each analysis of variance vere calculated by multiplying the <br />standard error of the differences between means by the tabular value of <br />Students' t with the degrees of freedom of the error mean square. <br /> <br />10 <br />
