<br />u <br />\J <br />Sample Adequacy <br />A summary of sample adequacy calculations for the parameters of cover, herbaceous <br />production, and woody stem density is presented in Table 15 (Appendix 1). <br />Details of a two-stage sampling design and the formula used to sample woody stem <br />density and calculate variance in Wadge Pasture was detailed in the Methods section. <br />The results of this variance calculation are expressed below: <br />1-(15/20) <br />VY= 9.11 <br />15 <br />1-(3/607) <br />+ 31.07 = 0.84 <br />3X15 <br />The result of the sample adequacy calculation determined using this variance (0.84) was <br />that with a sample size of fifteen (the number of primary units), the minimum sample size <br />required (using aone-tailed t-value with fourteen degrees of freedom: t= 1.345) was <br />five. <br />15 <br /> <br />
