Resumo: | Protected areas by the law represent one of the strategies for biodiversity conservation, especially in regions under strong human pressure. However, many of these protected areas present barriers that prevent natural regeneration and knowing them becomes essential. In this sense, the objective of this work was to verify the regeneration potential of a restoration plantation carried out in a Conservation Unit, by quantifying the contribution of diaspores and the formation of young individuals. Seed collectors and natural regeneration plots were launched in a plantation carried out at the Fontes do Ipiranga State Park, São Paulo, SP. 54 species (41 arboreal) were identified and 24,033 propagules (17,775 of the invasive species Urochloa decumbens) were registered and regarding seedling recruitment there were 58 species (16 arboreal). The regeneration potential was still greatly influenced by the conditions of the area and the strong presence of invasive grasses, combined with the low diversity of tree species identified in the seed rain and in the recruitment of seedlings, had compromised the process. |

Porém, muitas dessas áreas protegidas apresentam barreiras impeditivas à regeneração natural e conhecê-las torna-se primordial. Nesse sentido, o objetivo deste trabalho foi verificar o potencial de regeneração de um plantio de restauração realizado em uma Unidade de Conservação, por meio da quantificação do aporte de diásporos e da formação de indivíduos jovens. Para isso, foram instalados coletores de sementes e parcelas de regeneração natural num plantio realizado no Parque Estadual das Fontes do Ipiranga, São Paulo, SP. Foram identificadas 54 espécies (41 arbóreas) e registrados 24.033 propágulos (17.775 da espécie invasora Urochloa decumbens) e quanto ao recrutamento de plântulas foram 58 espécies (16 arbóreas). O potencial de regeneração foi influenciado pelas condições da área, e a forte presença de gramíneas invasoras, aliada à baixa diversidade de espécies arbóreas identificadas na chuva de sementes e no recrutamento de plântulas, tem comprometido o processo.Universidade Federal de Santa Maria2021-06-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttps://periodicos.ufsm.br/cienciaflorestal/article/view/4365910.5902/1980509843659Ciência Florestal; Vol. 31 No. 2 (2021); 786-807Ciência Florestal; v. 31 n. 2 (2021); 786-8071980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/43659/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/43659/htmlCopyright (c) 2021 Ciência Florestalinfo:eu-repo/semantics/openAccessBarbosa, Karina CavalheiroCatharino, Eduardo Luis MartinsBarbosa, Luiz MauroCouto, Hilton Thadeu Zarate doSantos Junior, Nelson Augusto2021-08-24T13:31:11Zoai:ojs.pkp.sfu.ca:article/43659Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2021-08-24T13:31:11Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
