Resumo: | The knowledge of forest populations dynamics after logging and under the events of silvicultural treatments is important to establish management and conservation strategies. We aimed to show results of structural changes of tree species populations (from seedlings to adult trees), during 27 years in an area where reduced impact logging and silvicultural treatments were performed. In 1985 timber of trees with DBH ≥ 60 cm was logged from 400 ha, considering three volume reduction intensities (15, 25, 35%). In 1994, thinning was applied considering individuals with DBH ≥ 15 cm, and four intensities of basal area reduction (0, 30, 50, 70%). Twelve statistical treatments were performed considering the thinning combined with harvest intensities. Trees, saplings, sticks and seedlings were monitored and measured in 40 permanent sample plots. The plots were assessed in 1984, 1986, 1994, 1996, 2004 and 2011. Statistical analyses were performed using generalized linear models. Our results show that forest structure was not altered significantly even in areas where the trees basal area reduction was higher. There was no significant influence on the establishment of the main species in the area and in dynamics of the remnant forest after logging. |

O objetivo desse trabalho foi mostrar resultados da mudança estrutural das populações de espécies arbóreas (de mudas a árvores adultas), durante 27 anos, em uma área com colheita de madeira e aplicação de tratamentos silviculturais. Em 1985, colheu-se madeira com DAP ≥ 60 cm, em 400 ha, com três intensidades de redução volumétrica (15, 25, 35%). Em 1994, realizou-se desbaste dos indivíduos com DAP ≥ 15 cm, com quatro intensidades de redução da área basal (0, 30, 50, 70%). Doze tratamentos estatísticos foram aplicados, considerando-se desbaste combinado com intensidades de colheita. O monitoramento ocorreu em 40 parcelas permanentes, medindo-se árvores, arvoretas, varas e mudas em 1984, 1986, 1994, 1996, 2004 e 2011. Realizou-se análises estatísticas com modelos lineares generalizados. A estrutura da floresta não foi alterada significativamente, mesmo nas áreas onde foram aplicados tratamentos silviculturais com maior redução de área basal, não sendo registrada influência significativa no estabelecimento das principais espécies na área, nem na dinâmica da floresta remanescente.Embrapa Florestas2023-10-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/octet-streamhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/213910.4336/2023.pfb.43e202002139Pesquisa Florestal Brasileira; v. 43 (2023)Pesquisa Florestal Brasileira; Vol. 43 (2023)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/2139/1701Copyright (c) 2023 Fernanda da Silva Mendes, Renildo Medeiros da Silva, Ademir Roberto Ruschel, Aurélio Lourenço Rodrigues, João Olegário Pereira de Carvalho, Sebastião do Amaral Machado, Afonso Figueiredo Filhohttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessMendes, Fernanda da SilvaSilva, Renildo Medeiros daRuschel, Ademir RobertoCarvalho, João Olegário Pereira deRodrigues, Aurélio LourençoMachado, Sebastião do AmaralFigueiredo Filho, Afonso2023-04-03T11:01:18Zoai:pfb.cnpf.embrapa.br/pfb:article/2139Revistahttps://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:2023-04-03T11:01:18Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
