ResumenLitterfall was studied in four representative forests of Paraná River floodplain in the Pre-Delta area (Argentina) during 1998-2002 period. The objectives of this study were to describe and compare litter fall values of different forests, and analyze the relationship between litter fall and flooding pulse. Forests dominated by S. humbolditiana and by T. integrifolia had similar productivity values (5.32-8.19 Mg ha-1y-1 and 4.55-7.85 Mg ha-1y-1, respectively), but they were different from the other two studied forests. In addition, timbó blanco (A. inundata) and laurel del río (N. angustifolia) forests had different contribution rates (2.62-3.69 Mg ha-1y-1 and 8.8-10.34 Mg ha-1y-1, respectively, p<0.0001). All these values are close to other estimations for subtropicaal forest in flooded areas. Leaves are the dominant fraction in litterfall. The litter-fall has a seasonal pattern associated with the hydrological pulse.
