ABSTRACT
How does species choice influence ecological restoration outcomes? In order to answer this
question, the goal of this study was to assess the community structure and species richness of
natural regeneration beneath the canopy of four native species from the Atlantic Forest (Guarea
guidonia (L.) Sleumer; Inga edulis Mart; Nectandra membranacea (SW) Griseb; and, Piptadenia
gonoacantha (Mart.) J.F. Macbr). The research was carried out in plantations of native tree species
at the Guapiaçu Ecological Reserve, in Rio de Janeiro State, Brazil. Our results pointed that
abundance, basal area and species richness were significantly higher beneath Inga compared to
Nectandra and Guarea. Whereas the lowest values observed in Guarea may suggest its negative
effects under natural regeneration. Therefore, we highlighted that the positive or negative
biological effects of tree species, instead of their simple response (mortality and initial growth),
must be considered in ecological restoration projects.
Keywords: Atlantic Forest, ecological filter, plant-plant interaction, facilitation, Inga edulis.
