In 1983 an extraordinary flood destroyed the Panicum prionitis tall grassland in the Parana River Valley. In this paper phytosociological analyses of the communities, which in March 1988 were in the place of the tall grassland along the transect from El Rabon to Puerto Piracuacito, are presented. These are compared with a previous analysis performed immediately following the flood. It is shown that pioneer communities evolve convergently into tall grassland with slightly different variants. Panicum prionitis partially recovers and its ground cover is inversely proportional to the Cynodon dactylon cover. Floristic richness and diversity decrease. As the floristic composition change, the proportions of therophytes decrease and the phanerophytes increase. It is concluded that exposed to an extraordinary flood, the Panicum prionitis grassland is very resilient. |
