Abstract

CIELO-FILHO, Roque et al. Tree and shrub flora in the surroundings of the Parque Nacional do Iguaçu, Paraná State, Brazil: contribution to ecological restoration. Hoehnea [online]. 2017, vol.44, n.4, pp.473-489. ISSN 2236-8906.  https://doi.org/10.1590/2236-8906-97/2016.

Aiming to expand the regional floristic knowledge and compile species information to subsidize restoration projects, we conducted a floristic survey in native forest fragments of an area located between the Parque Nacionaldo Iguaçu and the Área de Preservação Permanente do Lago de Itaipu, in western Paraná State. We found 204 species and 51 families, being the richest Fabaceae (29 spp.), Myrtaceae (18 spp.), Solanaceae (10 spp.), Euphorbiaceae, Meliaceae and Rutaceae (nine spp. each). The zoochoric syndrome was the most common (69% of the species), followed by anemochoric (17%) and autochoric (14%). The non-pioneer species were the most frequent (64%). In general terms, these results agree qualitatively with those observed in seasonal semideciduous forests. Based on phytosociological data from other studies, we indicated 34 locally abundant species that can be used in greater proportions in restoration projects. We recorded seven species threatened and 15 exotic, of which 12 have invasive potential and require actions for controlling.
