Short summary
We used high-resolution satellite images to analyze woody vegetation (trees and shrubs) across African savannas. By delineating individual tree crowns we estimated the number of trees, sizes of crowns, and the spatial pattern of woody vegetation in the landscape. We find several interesting relationships for how vegetation properties (including the emergence of highly organized periodic vegetation patterns) are influenced by the local environment.
