Abstract

Considering the growing need for new models for forest restoration, the present study had the objective of evaluating the high diversity of plant species, functions and density in forest restoration, resulting in the recovery of the system’s stability, and the conditions or processes that affected the restoration of ecological functionality in the systems evaluated. For this, a restoration indicator protocol was applied in a reference area and in three restoration areas, in a semideciduous seasonal forest, a dense-diverse- functional model (3 seedlings per m²), with 53 months of age and two in the model of fill and diversity (spacing 3 × 2m), with 35 and 60 months of age, respectively. The results indicate that the dense-diverse-functional model is efficient in the restoration of the ecological functionality at 53 months and differs from the system fill and diversity in relation to the conditions needed to promote soil protection and litter loading.
