Resumo: | The cattle grazing is a common economic activity on montane forests (MFs) in subtropical highlands of Santa Catarina state, southern Brazil. There is no study on this impact on MFs. The aim of this study was to investigate changes in floristic and structure in the MFs(~1,700m.a.s.l) with different successional and levels of impact of cattle grazing in farms not expropriated located in São Joaquim National Park. Six plots with 1000m2 were installed in the same mountain side (small variations in environmental conditions among sites) and two areas around the mountain. All arboreal component (shrubs and trees) in two classes (A= height>0,2m e DBH<1,9 cm e B= DBH≥1,9cm) were sampled. Most arboreal species of MFs tend to be tolerant of low and intermediate levels of cattle grazing. Species richness was higher in MFs with low and medium intensity impact grazing. Most other structural attributes varied their response to grazing levels and successional stage of the forest. In general, the intense grazing in understory changed over the composition and structure of the regenerative component (Alt> 0.2m and DAP <1.9cm) than with larger plants. To promote sustainable grazing systems in Legal Reserve Areas, many studies are still needed. However, passive restoration has proven effective to restore cloud forests which suffer the impact of with cattle grazing. |

Frente à abrangência deste impacto e a inexistência de estudos que avaliem a magnitude desta perturbação, foram investigadas as mudanças na composição florística e estrutura do componente arbóreo em uma cronossequência das FN em diferentes níveis de intensidade de pastoreio (fraco, médio, forte e com abandono) em áreas privadas não desapropriadas do Parque Nacional de São Joaquim, Urubici - SC. Oito parcelas de 1.000 m2 foram instaladas nas FN (seis áreas próximas e dentro de um mesmo fragmento de encosta e duas áreas de floresta em estágio inicial fora deste fragmento) e amostradas todas as espécies arbóreas (arbustos e árvores) em duas classes de tamanho (Cl.1 = Alt > 0,2 m e DAP < 1,9 cm e Cl.2 = DAP ≥ 1,9 cm). A maioria das espécies arbóreas foi tolerante aos níveis baixos e intermediários de pastoreio e, por isso, poucos padrões florísticos foram revelados entre as florestas secundárias, exceto nos estandes bem jovens e os mais antigos. De forma geral, o pastoreio intenso no sub-bosque alterou mais a composição e estrutura do componente regenerativo (Cl.1) do que as plantas já estabelecidas (Cl.2). No entanto, o uso da restauração passiva parece ser suficiente para recuperação das FN não fortemente impactadas pelo pastoreio no Planalto Catarinense.Universidade Federal de Santa Maria2020-04-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/2117910.5902/1980509821179Ciência Florestal; Vol. 30 No. 1 (2020); 1-17Ciência Florestal; v. 30 n. 1 (2020); 1-171980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/21179/23363Copyright (c) 2020 Ciência Florestalinfo:eu-repo/semantics/openAccessKilca, Ricardo VargasHiguchi, PedroSilva, Ana Carolina da2020-09-02T20:44:36Zoai:ojs.pkp.sfu.ca:article/21179Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2020-09-02T20:44:36Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
