Resumen:
Nothofagus pumilio is the most important timber native species in Patagonian forest. There is not any site index equation for lenga forest. So, the aim of this work was to provide an equation for Nothofagus pumilio based. One hundred trees were selected along ten sites to make stem analysis and the obtained data was used in the nonlinear regression analysis. The constrained Weibull-type site index model was selected, because it showed the best statistics and 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 satisfies some information required for different management regimes and silvicultural situations on lenga forest.
