Resumo: | Natural regeneration is one of the most appropriate techniques to promote the restoration of vegetation in degraded areas. Thus, this study aimed to evaluate the composition and the structure of the tree and regenerative strata in three areas under natural regeneration, characterized by different ages after the removal of stands of Eucalyptus grandis. The study area is located in the basin of Itajai river in Brusque, SC state. Data collection was performed with the deployment of 56 sample units (AU) of 200 m² distributed along the banks of a watercourse in areas that had five periods (AT I), three (AT II) and one and a half (AT III) years of abandonment. In each AU, individuals living with PAP ≥ 5 cm and height greater than 1.3 m were sampled. To survey the regenerative stratum, it was demarcated a subunit of 20 m² within each AU of tree communities where the plants were sampled with height ≤ 1,30 m. The studied vegetation presented distinctions in structural values, showing a succession dynamics during the study period. The pioneering suffered decrease in number of species, both in the tree layer as the regenerative, while shade-tolerant climax species had recruitments along with the advancement of the age of abandoned areas. The number of plants for ecological groups showed more pronounced changes in the regeneration layer with the increased abandonment period of areas and pioneer species decreased while the demanding climax light increased in density. |

Assim, o presente estudo teve por objetivo avaliar a composição e estrutura dos estratos arbóreo e regenerativo em três áreas sob regeneração natural, caracterizados por diferentes idades após retirada de povoamentos de Eucalyptus grandis. A área de estudo localiza-se na bacia hidrográfica do rio Itajaí, em Brusque - SC. A coleta dos dados foi realizada com a implantação de 56 unidades amostrais (UA) de 200 m² distribuídas ao longo das margens de um curso d'água em áreas que apresentavam períodos de cinco (AT I), três (AT II) e um e meio (AT III) anos de abandono. Em cada UA foram amostrados os indivíduos vivos com PAP ≥ 5 cm e altura maior que 1,3 m. Para o levantamento do estrato regenerativo, foi demarcada uma subunidade de 20 m² dentro de cada UA do estrato arbóreo, no qual foram amostradas as plantas com altura ≤ 1,30 m. A vegetação estudada apresentou distinções em valores estruturais, evidenciando um dinamismo sucessional no período avaliado. As pioneiras sofreram decréscimo em número de espécies, tanto no estrato arbóreo quanto no regenerativo, enquanto que as espécies clímax tolerantes à sombra apresentaram ingressos com o avanço da idade de abandono das áreas. O número de indivíduos por grupos ecológicos sofreu alterações mais evidentes no estrato regenerativo com o aumento do período de abandono das áreas e as pioneiras diminuíram enquanto que as espécies clímax exigentes em luz aumentaram em densidade.Universidade Federal de Santa Maria2017-03-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/2644310.5902/1980509826443Ciência Florestal; Vol. 27 No. 1 (2017); 1-19Ciência Florestal; v. 27 n. 1 (2017); 1-191980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/26443/pdfCopyright (c) 2017 Ciência Florestalinfo:eu-repo/semantics/openAccessSeubert, Rafaela CristinaMaçaneiro, João PauloSchorn, Lauri AmândioSebold, Deisi Cristine2017-04-04T14:09:48Zoai:ojs.pkp.sfu.ca:article/26443Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-04-04T14:09:48Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
