| description | The present study aimed to characterize the spatiotemporal variability of aboveground biomass and carbon in two fragments of Dry Tropical Forest in the Brazilian semi-arid region using the kriging interpolation technique. One fragment experienced vegetation suppression for alternative land use, while the other had no history of use or wood extraction. The vertices of 80 plots (20 m x 20 m) were georeferenced, and biomass and carbon were estimated using allometric equations adjusted for Caatinga species. Spatial analyses and mapping of aboveground biomass and carbon were performed using GS+ software, with semivariograms fitted using spherical, exponential, and Gaussian models. The research aims to fill gaps regarding the impacts of inadequate forest exploitation in Dry Tropical Forests, specifically on the spatiotemporal distribution of biomass and carbon, as anthropogenic pressure can cause significant environmental degradation, resulting in reduced stocks. This investigation seeks to elucidate these dynamics and provide insights for management and conservation strategies based on robust empirical data, in addition to answering the following questions: Does the history of anthropogenic interventions in Dry Tropical Forest areas cause variations in the spatial distribution of biomass and carbon stocks that can be detected by the kriging method? Which attributes related to conservation and anthropogenic use reflect the spatial distribution of biomass and carbon stocks in Dry Tropical Forest areas? The results showed a strong spatial dependence of biomass and carbon stocks in both studied areas, indicating the influence of the areas’ use history. The conserved fragment presented a more homogeneous spatial distribution, suggesting that the selective and unauthorized wood extraction was dispersed throughout the area. |
