metadata.revistascielo.dc.description: Two no thinned stands of Tectona grandis L.f, situated in the Baixo Rio Acre microregion, Rio Branco, Acre were analyzed: the first stand with 2.083 trees/ha and the second with 1.111 trees/ha. The objectives of the work were: to determine the optimum economic rotation (OER), to evaluate the economic viability and analyze the sensitivity of the economic indicators as regards the oscillation of the minimum attractiveness rate (MAR) and cost reduction. The economic criteria were the net present value (NPV) and equivalent periodic benefit (EPB). To measure the land heritage shadow cost the land expected value was employed. The results of the economic analysis showed that the OER based on the maximization values of NPV and EPB, considering a minimum attractiveness rate of 10 per year, it was possible to foresee for the next 25 years of age in area 1 at the 27 years of age in area 2. The teak stands evaluated are economically viable for a MAR of 10% per year; the stand of area 1 presented better results for NPV and EPB, than that of area 2; if maintained the same levels of investment and MAR superior to 12. 67% shows that the investment in unthinned stands would not be an attractive investment.
