(Bonham, 1974). To calculate this index, the following formula was given by <br />McIntosh (1967): <br />s <br />Djh = < (Xi' - Xih)2 <br />1 <br />Where (X) is the number or some measure of the ith species in the two stands, j <br />and h: and (S) is the total number of species encountered. <br />In explaining his concept, McIntosh (1967) stated that a sample from a community <br />may be located as a point in space. The occurrence of this point in hyperspace <br />is given by the following formula: <br />s <br />nit <br />i = 1 <br />where n refers to the number of individuals of a single species and (s) has the <br />• same value as the previous formula. McIntosh (1967) concluded that the above <br />formula is a true measure of diversity since it "... is dependent upon the number <br />of individuals in the sample and their distribution among species." In order to <br />determine the diversity (1) of any sample directly, the following formula was ' <br />suggested by McIntosh (1967): <br />s <br />D=N -? ni 2 <br />i = 1 <br />where (N) refers to the total number of individuals in the sampled population and <br />may be taken as unity (Bonham, 1974). <br />The method of describing vegetation in terms of diversity is based on the object- <br />ives of the study. One method used by Bonham (1974) was designed to detect the <br />dissimilarity between groups and was based on the relative cover values of common <br />0 3-65
