Resumo: | The Montane Ombrophilous Dense Forest belongs to Atlantic Forest’s domain, an important biodiversity hotspot. In Brazil, most of the invasion reports are related to terrestrial plants, being this forest the most affected. In this context is the Cantareira State Park (PEC), Sao Paulo. The PEC is home to a remnant that has a focus of invasion by several plant species, including Livistona chinensis (N.J. Jacquin) R. Brown ex Mart., known as Chinese Fan Palm. Given the potential for invasion of this species, a floristic-phytosociological study was conducted in order to analyse a possible inhibition effect in the natural regeneration process of the arboreous component caused by juveniles individuals of Livistona chinensis, with heights varying between 3 and 6 m. For each palm were installed 8 plots of 1 x 1 m, placed in quadrants, with the palm’s stipe in the center, in a way that half of the plots were placed under the canopy and half around the palm. In the analysis were considered arboreal and palms specimens ≥ 20 cm in height and with a Perimeter at Breast Height (PAP) ≤ 15 cm. The results pointed to a drastic reduced number of seedlings and saplings (28.95% and 29.85%) and of the species richness (16.13% and 8.33% of species) occurring under the canopies of these exotic palm trees in comparison with the surroundings (71.05% and 70.15% of the sampled individuals; and 61.29% and 58.33% of species, respectively). The study has shown the inhibiting effect of young individuals of this species on the forest regeneration in the PEC, by substantially reducing the richness of species and the abundance of arboreal individuals under the projection of their canopies, possibly because they serve as a shield and cause excessive shading of the place. |

No Brasil, a maioria dos casos de invasões biológicas deve-se a plantas terrestres, sendo essa formação vegetal a que apresenta o maior número de ocorrências. Nesse contexto está o Parque Estadual da Cantareira (PEC), em São Paulo. O PEC abriga um remanescente que apresenta focos de invasão por espécies exóticas, entre elas Livistona chinensis (N.J.Jacquin) R.Brown ex Mart., a palmeira-leque-da-China. Devido ao potencial de invasão dessa espécie, foi conduzido um estudo florístico-fitossociológico sobre o efeito de inibição da regeneração natural do componente arbóreo por indivíduos jovens de Livistona chinensis, com alturas de 3 e 6 m. Para cada palmeira, foram instaladas 8 parcelas de 1 x 1 m, distribuídas dentro de quatro quadrantes, tendo a estipe da palmeira ao centro, de forma que metade das parcelas ficaram localizadas embaixo da copa e metade ao redor. Na análise foram considerados os espécimes arbóreos e de palmeiras com altura ≥ 20 cm e com Perímetro à Altura do Peito (PAP) ≤ 15 cm. Os resultados apontaram uma drástica redução do número de indivíduos regenerantes (28,95% e 29,85% dos indivíduos amostrados) e da riqueza de espécies (16,13% e 8,33% das espécies) ocorrendo sob a projeção das copas dessas palmeiras em comparação com o entorno (71,05% e 70,15% dos indivíduos e 61,29% e 58,33% das espécies, respectivamente). O estudo mostrou o efeito de inibição de indivíduos jovens dessa espécie sobre a regeneração florestal no PEC, ao reduzir substancialmente a riqueza de espécies e a abundância de indivíduos arbóreos sob a projeção das suas copas, possivelmente por servirem de anteparo e causarem o sombreamento excessivo do local.Universidade Federal de Santa Maria2022-11-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/xmlhttps://periodicos.ufsm.br/cienciaflorestal/article/view/6856010.5902/1980509868560Ciência Florestal; Vol. 32 No. 4 (2022); 2304-2324Ciência Florestal; v. 32 n. 4 (2022); 2304-23241980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/68560/49482https://periodicos.ufsm.br/cienciaflorestal/article/view/68560/52417Copyright (c) 2022 Ciência Florestalhttp://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccessMangolini, Tânia GirãoArzolla, Frederico Alexandre Roccia Dal Pozzo2023-04-14T16:06:36Zoai:ojs.pkp.sfu.ca:article/68560Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2023-04-14T16:06:36Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
