摘要

Forest landscape restoration (FLR) models with attractive economic potential are needed to pique the interest and to be adopted by private landowners—who own most of the land in Paraguay—to connect the fragments of the Paraguayan Atlantic Forest. This chapter contextualizes the process of deforestation, degradation, and fragmentation of Paraguay’s forests while also showcasing the first forest restoration initiatives in the country and recording the incipient results for the economic approach, which considers functional groups of tree species as well as the use of forest products. To establish this economically attractive approach, an experimental plot was installed in 2021 in areas belonging to the Itaipú Binacional entity in eastern Paraguay. Eight treatments were tested in a randomized block design where strips emphasized different management goals. Monitoring was carried out for up to 18 months, and the preliminary results reveal five identified treatments delivering significant differences with superior management options with respect to the survival of the species composing the strips; in the analysis of dendrometric variables, Eucalyptus stands out as a facilitating exotic species. This experimental area serves as a demonstration site for adoption by interested parties.
