“…Although we did not evaluate the final, decisive criterion -the invasion itself (defined as the spread into areas away from the introduction sites) -some traits of R. oleracea indicated that invasion is likely to occur in the short-term. In fact, Nascimento et al (2013) showed that this palm is dispersing naturally over long distances (up to 440 m) in wetland areas of a protected area within the Atlantic Forest, where it was introduced around 1930. The combination of high productivity, high germination rates, and seed dispersal by animals, as has previously been reported for R. oleracea (Henderson et al 1995;Lorenzi et al 2004), is common in exotic invaders (Van Kleunen et al 2010;Richardson & Pyšek 2012).…”

“…This palm has been reported to be invasive, especially in the swamps of Guiana (Henderson et al 1995), in Panama (Svenning 2002), and in the Atlantic Forest of Brazil (Nascimento et al 2013). Arboreal palms can have negative effects on the seedling recruitment of other plant species due to the fact that their vegetative structures drop to the ground (Peters et al 2004).…”

Here, we investigated the population structure of the exotic palm Roystonea oleracea in a swamp on an island within the Atlantic Forest Biome, evaluating its influence on the seedling recruitment of other plant species. The population structure was analyzed in six 4 × 30 m plots, within which we categorized all individuals by ontogenetic stage. The influence of R. oleracea on the seedling recruitment of other plant species was evaluated in 2 × 2 m plots established beneath palm crowns and in adjacent areas without palms. We recorded 53 R. oleracea individuals. The majority (56.6%) of the R. oleracea population was composed of immature adults, followed by mature adults. The density, richness and diversity of seedling species differed significantly between areas beneath and away from palms, the values being lower beneath R. oleracea crowns. Our results indicate that R. oleracea recruitment does not require human intervention, the number of reproductive individuals characterizing successful naturalization. This underscores the need for management policies aimed at palm eradication in order to avoid reductions in biodiversity.

“…The introduction of R. oleracea in different habitats has been well documented, such as in the Gamboa forest, Panama (Svenning, ) and, more recently, in wetlands in the Brazilian Atlantic forest (Nascimento et al ., ). The Orinoco river delta, which is dominated by swamps with a variety of flooding conditions, appears to be an optimal environment for Roystonea species.…”

“…This species is a large, tall‐stemmed palm and, due to its beauty and elegance, it has been introduced as an ornamental all over the tropics including Central and South America. In Brazil, it has been cultivated widely since the 1920s and it is now invasive in wetlands of the Atlantic forest (Nascimento et al ., ). It is naturalized in Guyana, Suriname, French Guiana, Antigua (Henderson, Galeano & Bernal, ; Zona, ) and Panama (Svenning, ).…”

In Venezuela, Roystonea oleracea commonly forms communities in flooded and swampy areas on fertile soils mainly in the northern portion of the Orinoco river basin. The density of R. oleracea varies across its range from dominating the canopy to being rare. Communities dominated by R. oleracea are distributed across the country from the east (Sucre and Monagas States) to the south-west (Barinas State). In the western-central region the Roystonea community is mainly present along the Tocuyo, Yaracuy and Aroa river basins. In all most cases, R. oleracea is found with other palms such as Bactris major var. major, trees including Tabebuia rosea, Ficus spp., Spondias mombin, Triplaris americana, Hura crepitans or herbs (e.g. Heliconia spp.). In the western part of its range, it is found with another set of species, including Anacardium excelsum, Hirtella spp. and the large palm Attalea butyracea; in the eastern parts of its range it is found with the climbing palm Desmoncus horridus subsp. horridus and the tree Virola surinamensis and the mangroves Rhizophora racemosa and Avicennia germinans in estuarine environments of the Orinoco Delta. Human intervention in these communities has been intense due to agriculture involving clearing for sugar cane and orange plantations, hunting and extraction of young parrots (Psittacidae) from nests for the pet trade. These activities have endangered the survival and conservation of R. oleracea forests, which have been greatly reduced across the country.

“…Roystonea oleracea es nativa de la región del Caribe y ha sido introducida en muchos países tropicales (Kahn & Moussa 1997). Reportes previos catalogan a R. oleracea como una especie invasora o naturalizada en humedales en Brasil, Guyana y Panamá (Henderson et al 1995;Svenning 2002;Nascimento et al 2013). En este trabajo nos propusimos: 1) reportar la presencia de R. oleracea en Ecuador; 2) estimar la abundancia en Isla Santay y la distribución potencial en Ecuador de R. oleracea; y 3) examinar la susceptibilidad climática de otros humedales Ramsar del Ecuador al establecimiento de esta palma introducida.…”

Reporte y distribución potencial de una palma exótica ornamental (Roystonea oleracea) en Ecuador

Resumen La palma Roystonea oleracea, nativa del Caribe, ha sido introducida en varios países tropicales como planta ornamental e invade en humedales de Brasil, Guyana y Panamá. En este estudio reportamos la presencia de R. oleracea en la región de la costa del Ecuador donde es ampliamente cultivada como ornamental. Mediante una imagen de satélite estimamos la abundancia y cobertura de la especie en Isla Santay, un humedal Ramsar ubicado en el río Guayas cerca del perímetro urbano al sur de la ciudad de Guayaquil. También, realizamos un modelo de distribución potencial de R. oleracea en Ecuador, usando BIOCLIM. En Isla Santay, la especie está naturalizada y cubre alrededor de 43 hectáreas. El modelo de distribución potencial muestra que, además de Isla Santay, hay otros cinco humedales Ramsar en la costa ecuatoriana susceptibles climáticamente al establecimiento de R. oleracea. Debido al potencial invasivo de esta especie en humedales, se recomienda prohibir su uso como planta ornamental en áreas cercanas a humedales en Ecuador. Estudios que monitoreen la naturalización e impactos ecológicos de R. oleracea en humedales de Ecuador son requeridos para establecer prioridades de manejo y contribuir con la conservación de estos importantes ecosistemas.
