Resumo
This research aimed to investigate the survival of seedlings of native forest species from the
Cerrado biome (savannah), planted in a pasture, and evaluate the natural regeneration process. The
study was part of a reforestation and forest restoration project and involved a hydrogel polymer. We planted 1,980 seedlings of 11 species. The post-planting mortality was 7.2% in the polymer compared
to 6.3% in the area without this product and was not statistically different. After 17 months of planting,
mortality was 43.7% in the area with the polymer versus 55.1% in the control area and was significantly
different from each other. In relation to natural regeneration, we found 130 individuals of 13 species and
nine botanical families. The Fabaceae was the most abundant family, representing 38.4% of the species.
The floristic diversity was 1.60 nats.indv-¹ and evenness of 0.62. The floristic similarity between the
natural regeneration and the seedling planting was 7.6%, with Myracrodruon urundeuva Allemão being
the only common species. Use of the hydrogel polymer has been considered effective to promote the
survival of the species, but the isolation area and the control of the Urochloa brizantha have become
evident to the success of the reforestation and forest restoration project.
