The site quality of plantations is estimated mainly by the local index used in forest management for growth and production models. The indices are obtained by mathematical models using variable Height dominant (Hd), however to obtain the measurements of this variable, its demands many economic resources at permanent plots inventories. In the present research, it was determined the efficiency of five Analytical Methods usage in the local Index estimation using the dominant Height (Hd) and the

The local indices method is the one that has given the best result, preliminarily defined with 23 % variation in the classification of plots as a function of the classification with the variable Hd. This method was adjusted with the Richards model, obtaining a coefficient of correlation between the observed data and the estimated 0,982. The dominant Dap variable can be used in the estimation of site quality.
