This work analyzes the volumetric and economic production of Eucalyptus urophylla S. T. Blake stands oriented to firewood production in a three-y ears cutting cycle, in the region of Ipameri, State of Goias . 1,545 trees were measured and rigorously scaled. T he volume data obtained was adjusted by Schumacher log-reciprocal model. The volumetrically optimal rotation was defined by the Mean Annual Increment and Land Expectation Value maximization criteria. The optimal rotation ages we re between 5 and 6 years, and the economically optimal rotations were around 3 years of age. In relation to the sampled data, it may be inferred that the optimal harvest age should be at age 4.
