REVEGETATION OF FILL SITES (ON-LAND SECTIONS) IN THE LOWER DELTA OF THE PARANÁ RIVER. This paper describes the restoration of vegetation cover over fill sites (on-land sections) located in a natural environment of the lower Delta of the Paraná River, where preexisting vegetation had been removed, and dredged material from the river bed had been disposed of. The main strategy was aimed at restoring vegetation observing the soil development of the filling.
