Resumo: | Monitoring through good ecological indicators is still a challenge in assessing the results of ecological restoration in Brazil. In this sense, the aim of this work was to evaluate ecological indicators of the restoration process by applied nucleation implanted two years and seven years ago in the south of Brazil. A total of twenty 5 m x 5 m plots were evaluated in each area, arranged systematically under the nuclei. All shrub-tree individuals with height greater than 30 cm were counted and identified. The species were classified according to the dispersion syndrome and shade tolerance. Shannon’s diversity and Pielou’s evenness indices were calculated. Canopy coverage was verified by a convex spherical densiometer. Analysis of variance (p <0.05) were used to compare floristic composition, structure and function group indicators between areas. We adjusted simple linear regression models between the area occupation of the nucleus and the richness and number of individuals of natural regeneration to verify the nuclei expansion. The results showed greater richness, diversity and canopy coverage percentage in the area with applied nucleation from seven years. There was a significant difference for composition, structure and function group indicators. The simple linear regression model for the nucleus area as a function of the number of individuals was significant (p<0.05). We concluded that the nuclei implanted seven years ago are being effective for ecological restoration. The post-implantation chronological period should be considered as a variable of influence on the effectiveness of the restoration. |

Nesse sentido, o objetivo deste trabalho é avaliar indicadores ecológicos do processo de restauração por plantio em núcleos implantados há dois e sete anos, no Rio Grande do Sul. Foram avaliadas 20 parcelas de 5 m x 5 m, em cada área, dispostas sistematicamente sob os núcleos. Todos os indivíduos arbustivo-arbóreos com altura superior a 30 cm foram contados e identificados. As espécies foram classificadas quanto à síndrome de dispersão e tolerância à sombra. Foram calculados o índice de diversidade de Shannon e a equabilidade de Pielou. A cobertura do dossel foi verificada com densiômetro esférico convexo. Análise de variância (p<0,05) foi utilizada para comparar indicadores de composição florística, estrutura e grupos funcionais entre as áreas. Modelos de regressão linear simples entre a área de ocupação dos núcleos e a riqueza e abundância da regeneração natural foram ajustados para verificar a expansão dos núcleos. Os resultados demonstraram maior riqueza, diversidade e percentual de cobertura de dossel na área com plantio em núcleos há sete anos. Houve diferença significativa para indicadores de composição, estrutura e grupos funcionais. O modelo de regressão linear simples para a área do núcleo em função do número de indivíduos foi significativo (p<0,05). Conclui-se que os núcleos implantados há sete anos estão sendo eficientes para a restauração ecológica. O período cronológico pós-implantação deve ser considerado como variável de influência na efetividade da restauração.Universidade Federal de Santa Maria2021-09-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttps://periodicos.ufsm.br/cienciaflorestal/article/view/4810510.5902/1980509848105Ciência Florestal; Vol. 31 No. 3 (2021); 1512-1534Ciência Florestal; v. 31 n. 3 (2021); 1512-15341980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/48105/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/48105/htmlCopyright (c) 2021 Ciência Florestalinfo:eu-repo/semantics/openAccessPiaia, Bruna BalestrinRovedder, Ana Paula MoreiraProcknow, DjoneyCamargo, Betina2021-09-06T21:13:38Zoai:ojs.pkp.sfu.ca:article/48105Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2021-09-06T21:13:38Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
