SUMMARY:

The study on the effects of fire and soil in Amazonian Savannas is essential for understanding the processes involved in the formation of these landscapes. However, little is still known about how the physicochemical attributes of the soil and the fire regime can shape the structure, biomass, and floristic composition of tree species in an Amazonian Savanna patch. Wildfire frequency and soil data were correlated with the structure, biomass, and species composition in plots distributed over 10,000 hectares of savannas in the Alter do Chão region, Pará. The analyses were conducted for the total set of species. A total of 3,520 tree individuals from 20 families and 28 species were recorded. Our analyses suggest that fire and soil have brought about changes in the landscape, influencing species richness and modifying their composition, as well as affecting the structure and biomass of these areas. Overall, our findings support the hypothesis that soil components, combined with fire, can induce alterations in the landscape across all its attributes in this savanna patch of the Amazon.
