Abstract
This study aims to analyze the spatial-temporal changes in Natural and Planted Forests in Brazil. To achieve this, data provided by MapBiomas was used to examine the development of Brazilian forests between 1985 and 2022. The forests were categorized as either Natural or Planted, highlighting their differences. Natural Forests are characterized by their role in preserving Brazil's biodiversity, while Planted Forests are cultivated primarily for commercial purposes. The data was analyzed using percentage variation and further examined through a paired T-test, the test was used to identify the existence of statistically significant differences between the years of analysis and Location Quotient analysis. The results indicate a positive trend in the growth of Planted Forests, while areas of Natural Forests have decreased across the country. Regarding the T-Test, the results indicated that, on average, the areas of Natural Forests in the Cerrado, Caatinga, Amazon and Atlantic Forest biomes are smaller in 2022 compared to the areas observed for these biomes in 1985. Furthermore, regarding the comparisons of the areas, the test indicated that Planted Forests, on average, in the Cerrado, Amazon, Atlantic Forest, Caatinga and Pampa biomes, are larger in 2022 than the areas observed in these biomes in 1985. Thus, we have a reduction in areas of natural forests in most Brazilian biomes, as well as an increase in areas of planted forests in the same biomes, added to the Pampa biome.
