Abstract
Consistent monitoring of trees inside and outside forests is crucial for sustainable land management. This study utilizes PlanetScope nanosatellite imagery to map African tree cover, revealing that 29% of tree cover exists outside previously classified forest areas. This high-resolution mapping (RMSE = 9.57%, bias = -6.9%) enables precise assessment of all tree-based ecosystems at a continental scale, potentially redefining land use impact assessments and informing natural climate solutions.
