Resumen:
Nothofagus pumilio is the most important timber native species in Patagonian forest. Since there is not any site index equation for lenga forest, we set as our aim to provide such an equation. One hundred trees were selected (along ten sites) for stem analysis and the data obtained were used in the nonlinear regression analysis. The constrained Weibull-type site index model was selected, because it showed the best statistics; it also has the property of H=S at index age. Base age at 60 years was selected, and a range SI60 of 9.8 to 23.22 m of total height was obtained. The use of this equation provides some of the information required for different management regimes and silvicultural situations on lenga forests.
