| Popis: | Remnant forest structure and increment by diameter class play a decisive role in the recovery volume for the next cutting cycle. Tree species in the Amazon Forest do not present a defined pattern of diameter structure, which is discussed here using Cedrela odorata L. as a case study The aim of this study was to identify, by simulation, recovery from logging in a real situation at three timber production sites, and the alternatives that are available to ensure commercial timber volume to a second cut cycle in the Brazilian Amazon. The study is concerned regarding the diametric classes of productive trees to the next cycle, the comparison demonstrates that one of the strategies recovers stock volume more quickly than expected in the cut cycle defined by Brazilian law. The number of trees remaining at the sites does not corroborate the common assumption that forest management depletes large diameter trees. This paper presents assessment strategies to evaluate and establish the diametric structure that would enable the possible recovery in the second cut cycle, depending on the volume logged during the first cut cycle. |
