Conteúdo: | In Southern Brazil, caívas, agroforestry systems within patches of Araucaria Forest that include cattle production, have been used historically throughout the region. Despite their importance for biodiversity conservation, this system is being progressively replaced with high-yield agricultural crops, resulting in forest loss. However, such a loss of native vegetation could be avoided by developing appropriate technologies to optimize production and conservation, thus making caívas more attractive to farmers. This research tested two alternatives to traditional caíva (TC) management to identify strategies to increase pasture yield while also maintaining forest regeneration potential. The two alternative strategies are: 1) winter overseeding of cultivated pasture on natural pasture (WOC); 2) replacing natural pasture with giant missionary perennial pasture (GMC). The experiment was conducted in eight caívas, from October 2014 to February 2017. Pasture yield was evaluated monthly, and soils were analyzed at the beginning and end of the experiment. Richness and density of forest regeneration were also assessed through surveys carried out every six months in all plots. Results show that both alternative strategies were effective in increasing pasture yield, pH, and base saturation in soil. Further, these alternatives showed no impact on the total organic carbon content in the soil or on forest seedling diversity and richness, but with TCs showing a higher rate of forest regeneration. These results indicate how research that develops strategies to optimize use can help to improve traditional productive systems, preserving their social, economic, and environmental importance for communities.
