“…Phytosociological studies (Caires 2015, Mendes 2017 inventoried forest remnants in this locality, suggesting that there are no "untouched" forests and that the regenerating forest retains the marks of this historical presence in its structure and composition (Oliveira 2015). However, some species are dispersing beyond the original point where they were initially cultivated, as is the case of the imperial palm (Roystonea oleracea) (Zucaratto et al 2020) and jackfruit tree (Artocarpus heterophyllus) (Caires 2015, Bergallo et al 2016.…”

“…Its dissemination in Brazil is associated with historical issues involving the Portuguese imperial family and its introduction as an ornamental tree, especially in old coffee farms. Once the species has reached the final stage of invasion on Ilha Grande, eradication or control measures are urgently required (Zucaratto et al 2020). Rodrigues (2021) showed, however, based on anatomical characteristics, that part of the individuals on Ilha Grande does not correspond only to Roystonea oleracea, but to two other very similar species, Roystonea brinquena and Roystonea regia.…”

“…Botanical and plant population ecology studies carried out on this island concentrated efforts in the region of Reserva Biológica Estadual da Praia do Sul (Araujo & Oliveira 1988, Oliveira 2002, Nunes-Freitas et al 2006, Cruz & Nunes-Freitas 2019 or focused on specific botanical families (Pederneiras et al 2012, Nunes-Freitas et al 2009, Santo 2016, Rosa 2017. As important as the works mentioned, there are those related to biological invasion (e.g., Ribas et al 2010, Caires 2015, Zucaratto et al 2020, endangered species (Vianna Filho et al 2020) and scientific dissemination (Caires 2021).…”

In the present study a specific and comprehensive analysis of the arboreal flora of Ilha Grande, located in the municipality of Angra dos Reis, on the southern coast of the state of Rio de Janeiro, Brazil, is presented. Unpublished data and contributions from studies already carried out at the site that investigated issues related to the composition and richness of tree species, the degree of threat, endemism and the history of occupation and/or changes in land use were gathered and analyzed. This study is part of the PPBio Mata Atlântica – Programa de Pesquisa em Biodiversidade (Biodiversity Research Program) which, through phytosociological inventories of the tree component, has been contributing, since 2010, to the increase in the floristic knowledge of Ilha Grande. The inventory identified 509 tree species, belonging to 220 genera and 74 families. Of these, 34 species were categorized as threatened, two of which are critically endangered, 18 are endangered and 14 are vulnerable. 53 exotic tree species were indicated. The results presented here reinforce the importance of these inventories as indispensable tools for the construction of strategies and actions for conservation, restoration and management of diversity in the context of the Atlantic Forest.

“…Palms are among the main groups of ornamental plants that are introduced as exotic all over the world, and some of them have become invasive (Fehr et al 2020;Zucaratto et al 2020). Studies have shown that invasive palms can reduce seedling recruitment of other plant species (Zucaratto & Pires 2014), cause the population decline of native palms (Mengardo & Pivello 2014;Condé et al 2016), and even generate cascade effects, causing, for example, an impoverishment of arthropod assemblage in invaded areas (Holmquist et al 2011).…”

Exotic palms are introduced as ornamental all over the world, with some of them become invasive. Here, we characterize the population status and the stage of invasion of the exotic palm Caryota urens in an Atlantic Forest Protected Area, southeastern Brazil. Palms were sampled in 2019 and 2020, in fifteen 10 x 10 m plots, placed from an alley of planted reproductive palms. All individuals inside plots were marked and classified in ontogenetic stages. The number of sampled individuals was 110 in 2019 and 114 in 2020; palms were recorded in six plots in 2019 (the furthest 330 m from the alley) and in eight plots in 2020 (the furthest 420 m from the alley). In 2020, most palms were on the earlier ontogenetic stages (seedlings and infants, 86 %), but we also recorded juveniles (10.5 %) and immatures (3.5 %), values similar to those found in 2019. The population structure observed and the natural expansion of the species inside the forest indicate that the palm has successfully established in the area and has become invasive. Management actions should be taken urgently in an attempt to contain the spreading to new locations or eradicate this palm from this protected area.
