Abstract

The objective of the study was to evaluate which forest restoration technique provides the greatest increase in richness, density, diversity and vegetation cover in the area under restoration. The following trail plots were carried out on: T1) Conducting natural regeneration; T2) Conducting natural regeneration by seedlings planting; T2) Transposition of soil; T3) Transposition of soil with planting of seedlings. The treatments were carried out in 15 repetitions. After three years, it was observed that for richness (average of 12.14 ± 3.77 species), density (average of 510.3 ± 222.9 individuals/m2), and coverage (average of 90.26 ± 9.19 %) there was no difference between treatments. Colonization is being carried out mainly by herbaceous, native, and anemochoric species. As well as shrubs and trees similar to positive reference areas. The planted seedlings not enough to contribute to the advent of new species. However, the slow growth of trees on the field can only generate contributions in the long term. Therefore, the interventions performed improved the general parameters and the most expressive results were observed in the treatments with higher intervention. However, the lack of effectiveness of some treatments did not provide the expected difference between them.
