The test will be one -tailed with eo = 0.1. However, <br />because the denominator in equation 6 is not quite as efficient as the denominator in <br />equation 5, the degrees of freedom must be calculated using equation 7. <br />(7) <br />2 2 2 <br />( S1 + S2 ) <br />df = ni 1 n2 I -2 <br />2 2 2 2 <br />S1 1 + s2 I <br />(nl - 1) (n` - I) (n2 - I) (n2 + I) <br />2 <br />Sl = release area sample variance, <br />s22 =reference area sample variation <br />n, = release area sample size and <br />n2 = reference area sample size. <br />Woody plant density will be determined by conducting a total census within each clump. <br />All shrub and tree species , which have been established over two growing seasons and <br />area alive and healthy, will be identified and counted. <br />The results of revegetation sampling studies will be contained in the annual <br />reclamation report.
