Regional, high-resolution mapping of vegetation cover and biomass is central to understanding changes to the terrestrial carbon cycle, especially in the context of carbon management. The third phase of the Global Forest Watch project aims to provide such information on a global scale. This study focuses on the multiscale analysis of tree cover and aboveground biomass, which is essential for understanding the dynamics of the terrestrial carbon cycle. The results of this study will provide valuable insights into the changes in tree cover and aboveground biomass, and their implications for carbon management.
