“…Among the species reported for the lagoon, six are mentioned with occurrence in the restingas of the Southeast Region: Delonix regia, Furcraea foetida, Megathyrsus maximus, Ricinus communis, Syzygium cumini and Terminalia catappa (Ribas 2018). Furcraea foetida and Megathyrsus maximus show serious invasive behavior, as verified by Machado et al (2020) in areas close to the lagoon in Serra da Tiririca. Havel et al (2015) point out that freshwater ecosystems have greater biodiversity per surface area than marine and terrestrial ecosystems and, at the same time, have been profoundly transformed by invasive exotic species linked to a wide variety of taxonomic groups.…”

“…The presence of these species in this restinga wetland goes against conservation, as one of the factors that aggravate environmental degradation is biological contamination by exotic plants (Machado et al 2020). Among the species reported for the lagoon, six are mentioned with occurrence in the restingas of the Southeast Region: Delonix regia, Furcraea foetida, Megathyrsus maximus, Ricinus communis, Syzygium cumini and Terminalia catappa (Ribas 2018).…”

Lagoa do São Bento is a coastal restinga wetland, remnant of a paleolake, located in Maricá, RJ. The study aimed to inventory native aquatic plants, make a floristic comparison with other coastal lagoons and analyze the regeneration of this community after anthropic impacts. In the floristic analysis of aquatic plants, 45 species were listed, 39 of which are Angiosperms and six are Ferns. Aeschynomene paniculata, Hymenachne amplexicaulis, Montrichardia linifera and Torenia thouarsii are new records for the municipality and Tabebuia cassinoides is threatened. Emerging plants (21 spp.) stand out, followed by amphibians (16 spp.), free floating (4 spp.), fixed floating (3 spp.) and tolerant (1 sp.). The comparison showed greater similarity with the Jacarepiá lagoon, in Saquarema, sharing 21 species. The phytosociological inventory listed 87 species, 83 of which were Angiosperms and four Ferns. The species with the highest IVI were: Fuirena umbellata, Pleroma gaudichaudianum, Xyris jupicai, Typha domingensis, Salvinia aff. auriculata, Eleocharis interstincta, Rhynchospora gigantea, Nymphoides humboldtiana, Nymphaea caerulea and Clitoria laurifolia. Shannon, Simpson and equity indexes were 3.83, 0.03 and 0.85, respectively. Native aquatic species represent the majority of the total inventoried (54%), with a considerable supply of exotic and ruderal, whose colonization reflects the anthropic interventions.

Dune slope, not wind speed, best predicts bare sand in vegetated coastal dunes

Globally vegetation cover on coastal sand dunes has increased since at least the 1950s. With the aim of restoring or increasing biodiversity, land managers in several countries have removed vegetation and/or reprofiled dune slopes to reinvigorate geomorphic activity. However, the longevity of these interventions can be relatively short (on the order of 5 to 10 years), and further active management is required. Hypotheses for controls on geomorphic activity on dunes have frequently suggested that wind speedis the most important controlling factor. Here we show dune slope to be the best predictor of bare sand at four predominantly vegetated coastal sand dunes in England and Wales. We suggest that bare sand on steep dune slopes is maintained by three important factors: (1) Wind erosion, due to topographic acceleration (2) Granular avalanches of unconsolidated sediment and (3) Rotational slumping of unstable slopes. Our results indicate that where land managers wish to ‘rejuvenate’ areas of bare sand, efforts should focus on steep windward dune slopes and reprofiling of the dune slope should mimic the concave profiles of active slope faces on active parabolic dunes with an overall slope angle of between 18° and 23° from the dune toe to the crest.
