A test of the relative height method in stands of pinus is presented in this work. The first study of case presented utilized data of 1200 trees scaling from Eucalyptus grandis W. Hill ex Maiden and Eucalyptus urophylla S. T. Blake hybrid to make inferences about the accuracy provided by the method, to develop one formula allowing the elimination and/or reduction the number of sample-trees in a forest inventory. The formula developed was hr= (Ht - 2)/ 2, where diameter together with dap and total height (Ht) were used to generate taper equations using procedures of analytical geometry. In a second case, the relative height method was tested in a forest inventory of a pinus stand. This same stand was inventoried by the usual method. According to thesc evaluations it was possible to conclude that the relative height method ressults in precise, now-based taper and solid volume estimates and trees be used instead of the usual method.
