Resumo: | The capacity of natural regeneration of native species in situations of competition with forest plantation trees can be considered an important factor in maintaining diversity. Therefore, the present study evaluated the natural regeneration of native species in the sub-forest of a settlement of Eucalyptus saligna Smith., located on the Biological Reservation of Saltinho – PE. To estimate the natural regeneration of the arboreal species, three stands of Eucalyptus saligna Smith were selected. In each one of them, 10 sub-units of 1.0 x 50 m were implanted, one being on the edge of the stand and the others with a distance of 10 m one from another. The analyses were established based on the level of inclusion of the arboreal species in natural regeneration with circumference from stem to height of 30 cm from the soil - (CAB0.30m) ≤ 15 cm, and the classes of heights were distributed as follows: Class 1- arboreal individuals with heights (H) 1.0 ≤ H ≤ 2.0; Class 2- with heights (H), 2 < H ≤ 3; and ; Class 3- with heights (H) >3.0 m. To evaluate the floristic diversity at the species level, the Shannon index was used (H´). In total, 302 live individuals were sampled, belonging to 23 botanical families, 31 genera and 39 species. Based upon the results, it is possible to conclude that the Eucalyptus saligna tree does not preclude the natural regeneration of native species in the stand understory, however the floristic structure of the community is also influenced by edaphic factors and vicinity of seed sources |

Diante disso, o presente estudo avaliou a regeneração natural de espécies nativas no sub-bosque de um povoamento de Eucalyptus saligna Smith., localizado na Reserva Biológica de Saltinho, PE. Para a análise da estimativa da regeneração natural das espécies arbóreas foram selecionados três talhões de Eucalyptus saligna Smith. Em cada um deles, foram implantadas parcelas de 1,0 x 50 m, sendo uma na extremidade do talhão e as outras distanciando 10 m de uma da outra, totalizando dez subunidades. As análises foram estabelecidas, com base no nível de inclusão das espécies arbóreas em regeneração natural com Circunferência do Caule a Altura de 30 cm do solo - (CAB0,30m) ≤ 15 cm, e as classes de alturas foram assim distribuídas: Classe 1 com indivíduos arbóreos com altura (H) 1,0 ≤ H ≤ 2,0, a Classe 2 com altura (H), 2 < H ≤ 3 e a Classe 3 com altura (H) >3,0 m. Para avaliar a diversidade florística a nível de espécie utilizou-se o índice de Shannon (H´). No total, foram amostrados 302 indíviduos vivos, pertencentes a 23 famílias botânicas, 31 gêneros e 39 espécies. Analisando-se os resultados obtidos pode-se concluir que o eucalipto possibilita a regeneração de espécies nativas no sub-bosque, contudo, a composição florística depende também de características edáficas e da proximidade de fontes de propágulos.Universidade Federal de Santa Maria2011-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/321810.5902/198050983218Ciência Florestal; Vol. 21 No. 2 (2011); 183-192Ciência Florestal; v. 21 n. 2 (2011); 183-1921980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/3218/2207Alencar, Antonia Lidiane deMarangon, Luiz CarlosFeliciano, Ana Lícia PatriotaFerreira, Rinaldo Luiz CaracioloTeixeira, Lucineide de Jesusinfo:eu-repo/semantics/openAccess2017-05-03T18:14:27Zoai:ojs.pkp.sfu.ca:article/3218Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-05-03T18:14:27Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
