In misiones, Argentina, natural regeneration was examined in forests harvested by minimum diameters (MD) and uniform spacing (US). Three years after harvesting, a total of 22,300 seedlings/ha were found in the forest cut by MD, 54,300 seedlings/ha in the forest cut by US, and 33,000 seedlings/ha in undisturbed forest. The degree of canopy closure and understory plat composition were also examined. Forest harvest methods with reduced impact techniques can contribute to maintain high levels of plant diversity and habitat heterogenity. In richment trials for the rehabilitation of over-exploited forests, the most successful species were Bastardiopsis densiflora, Ocotea puberula, Enterolobim contortisiliquum, Cordia trichotoma and Peltophorum dubium. The use of non-timber species investment returns and makes this practice more profitable. These experiences are part of a CIFOR research network including Latin America and SE Asia
