Resumo: The aims of this study were to evaluate the Brazilian law parameters for tropical forest management regarding forest recovery and to propose alternative criteria to achieve sustainability, using Mezilaurus itauba (Meisn.) Taub. ex Mez as case study. The diameter structure was obtained from a 100% forest inventory of a 500 ha forest compartment. The assessment of M. itauba growth, ingrowth and mortality were carried out in a two sample plot of 50 ha located on the compartment, where all commercial species were measured both before and 7 years after logging. First it was evaluated the species structure and its most productive diameter class. The species recovery of timber volume has been simulated for the minimum logging diameter (MLD) of 50, 60, 70 and 80 cm. The largest volume recover was reached for the 60 cm MLD class. We showed that there is a diametric limit to achieve net timber volume production and that different remnant structures produce different increments.

Taub. ex Mez como caso de estudo. A estrutura diamétrica foi obtida de inventário 100% em um talhão de 500 ha. Os dados de crescimento, recrutamento e mortalidade de M. itauba foram adquiridos de 2 parcelas de 50 ha instaladas no talhão, em que todas as espécies comerciais foram medidas antes e após 7 anos da exploração. Foram avaliadas previamente a estrutura da espécie e sua classe diamétrica mais produtiva em volume. Posteriormente, foi simulada a recuperação em volume para os diâmetros limite de corte (DLC) de 50, 60, 70 e 80 cm. A maior produção ocorreu com DLC de 60 cm. O trabalho evidenciou que existe um limite diamétrico para a produção líquida de volume de madeira e que distintas estruturas remanescentes produzem incrementos diferentes.Embrapa Florestas2018-10-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/164810.4336/2018.pfb.38e201801648Pesquisa Florestal Brasileira; v. 38 (2018)Pesquisa Florestal Brasileira; Vol. 38 (2018)1983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1648/746Braz, Evaldo MuñozCanetti, AlineMattos, Patricia PovoaBasso, Renato OlivirFigueiredo Filho, Afonsoinfo:eu-repo/semantics/openAccess2019-05-10T19:43:45Zoai:pfb.cnpf.embrapa.br/pfb:article/1648Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2019-05-10T19:43:45Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
