Water infiltration research was carried out for this study in Andisols at 10 sites. Rainfall simulations were conducted on gentle, moderately-steep and steep slopes (10, 30 and 50%) to determine infiltration, runoff and soil loss as a function of the forest floor characteristics. The study results highlight the influential role played by the forest floor in infiltration and runoff. In pine forest, most of the rainwater remains in the duff and infiltration depends little therefore on the underlying mineral soil properties. In rainforest, the wetting front extends below the duff and the well-developed soil structure is a major factor in water infiltration. It is concluded that hydrophobic and cohesive duff layers lead to a major reduction in infiltration and that soil properties control infiltration when hydrophilic or loose duff is present. Soil erosion is not influenced by forest floor and remains low
