Resumo: | This study had the objective to analyze the floristic, structure and diversity of regeneration of a forest fragment located in the urban area of Dois Vizinhos, Paraná State. We used the census method and the traditional phytosociological descriptors as parameters of analysis, giving indications about the ecological value of the fragment. The results showed the occurrence of 231 individuals in 2,500 m² area, distributed in 35 species of 22 botanical families. The families with the highest number of species were Lauraceae and Myrtaceae, with three species each, followed by Boraginaceae, Euphorbiaceae, Fabaceae, Meliaceae, Myrsinaceae, Rosaceae and Sapindaceae with two species each. The others were represented by one species each. Among eight exotic species, four are potential invaders, such as Ligustrum lucidum (34.0%) and Dyospyrus kaki (13.6%) that presented high coverage value (CV) and dominance with more than 50% of the registered individuals. Most of the species belong to the initial stages of succession. In the regeneration, we found 20 species, with only tree exotics and, among them, only one invasive (L. lucidum). The occurrence of exotic invasive species in urban forest fragments requires attention of public managers to the necessity of silvicultural interventions to recover their floristic and original structure. |

Foram utilizados os descritores fitossociológicos tradicionais como parâmetros de análise, dando indicações sobre o valor ecológico do fragmento. Evidenciou-se a ocorrência de 231 indivíduos em 2.500 m² de área distribuídos em 35 espécies de 22 famílias botânicas. As famílias com maior número de espécies foram Lauraceae e Myrtaceae, com três espécies cada, seguida por Boraginaceae, Euphorbiaceae, Fabaceae, Meliaceae, Myrsinaceae, Rosaceae e Sapindaceae, com duas espécies cada, ficando as demais famílias com uma espécie cada. Entre as oito espécies exóticas, quatro são invasoras potenciais, tais como Ligustrum lucidum (34,04%) e Dyospyrus kaki (13,59%), destacando-se pelo alto valor de cobertura (VC) e pela dominância, com mais de 50% dos indivíduos. A maioria das espécies encontradas pertence a estágios iniciais de sucessão. Na regeneração, foram encontradas 20 espécies, com apenas três exóticas e, dentre estas, uma invasora (L. lucidum). A ocorrência de espécies exóticas invasoras em fragmentos florestais urbanos demanda a atenção dos gestores públicos quanto à necessidade de intervenções silviculturais, visando à recuperação da florística e estrutura original.Embrapa Florestas2017-12-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/140510.4336/2017.pfb.37.92.1405Pesquisa Florestal Brasileira; v. 37 n. 92 (2017): out./dez.; 503-512Pesquisa Florestal Brasileira; Vol. 37 No. 92 (2017): out./dez.; 503-5121983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1405/609https://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessKonig Brun, Flávia GizeleBrun, Eleandro JoséLonghi, Solon JonasGorenstein, Maurício RomeroMaria, Tamara Ribeiro Botelho CarvallhoRêgo, Géssica Mylena SantanaHiga, Thatiana Tominaga2019-01-02T18:39:23Zoai:pfb.cnpf.embrapa.br/pfb:article/1405Revistahttps://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:2019-01-02T18:39:23Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
