Resumo: This study aimed to evaluate the medium-term impacts of forest management on natural regeneration in central Amazon forest. The study was conducted in the logged forest belonging to Mil MadeirasPreciosas (Amazonas, Brazil). It was used data from continuous inventories that were carried out in 41 permanent parcels distributed in three Annual Production Units (APU), named APU B, C and D, logged in 1996, 1997 and 1998, respectively. In all units, forest inventories were carried out before logging and in the years 2001 and 2014; for APU B there was an additional inventory in 1998. The sample included trees with diameter at breast height between 5 cm and 14.9 cm. The species diversity analysis was performed by Shannon (H') and Pielou (J) indexes and the similarity analysis by Jaccard index and cluster analysis. The analyzes were made for all grouped species and commercial species group. A total of 8,090 trees families were sampled, distributed in 244 species and 48 families. Shannon index ranged from 3.77 to 4.08; Pielou index ranged from 0.74 to 0.84. There was a significant difference between H' for all species in two APUs 16 and 18 years after logging. There was significant difference between H' for commercial species before and 16 and 18 years after logging. Jaccard indexes ranged from 66.7% to 100%. The largest differences for the species composition were observed between pre-exploration inventories and the last measurement. Diversity and composition of species in the natural regeneration in the logged forest changed in a period by 16, 17 and 18 years after logging.

O estudo foi conduzido na área de manejo da empresa Mil Madeiras Preciosas (Amazonas, Brasil). Foram utilizados inventários contínuos realizados em 41 parcelas permanentes distribuídas em três Unidades de Produção Anual (UPA), denominadas UPAs B, C e D, exploradas em 1996, 1997 e 1998, respectivamente. Em todas as unidades foram realizados inventários antes da exploração e nos anos de 2001 e 2014; para a UPA B houve um inventário adicional no ano de 1998. O nível de inclusão neste estudo foram árvores com diâmetro à altura do peito entre 5 cm e 14,9 cm. A análise de diversidade de espécies foi realizada considerando os índices de Shannon (H’) e Pielou (J).A análise de similaridade considerou o índice de Jaccard e análises de agrupamentos. As análises foram feitas para todas as espécies agrupadas e para grupo comercial de espécies. Foram amostrados um total de 8.090 indivíduos distribuídos em 244 espécies e 48 famílias. O H’ variou de 3,77 a 4,08; o J variou de 0,74 a 0,84. Houve diferença significativa entre H’ para o conjunto de todas as espécies nas UPAs B e D, 18 e 16 anos após exploração, respectivamente. Houve diferença significativa entre H’ de espécies comerciais em duas unidades (C e D), 17 e 18 anos após a exploração. Os índices de Jaccard variaram de 66,7% a 100,0%. As maiores diferenças para composição de espécies foram observadas entre os inventários pré-exploração e a última medição. A regeneração natural da floresta sob manejo florestal sofreu alterações na diversidade e composição de espécies no período de 16, 17 e 18 anos após a exploração.Universidade Federal de Santa Maria2020-12-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/4188110.5902/1980509841881Ciência Florestal; Vol. 30 No. 4 (2020); 1116-1129Ciência Florestal; v. 30 n. 4 (2020); 1116-11291980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/41881/pdfCopyright (c) 2020 Ciência Florestalinfo:eu-repo/semantics/openAccessVinhote, Eirie GentilFreitas, Filipe Campos deAzevedo, Celso Paulo deSouza, Cintia Rodrigues de2021-05-20T04:00:51Zoai:ojs.pkp.sfu.ca:article/41881Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2021-05-20T04:00:51Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
