From: Sub-continental-scale carbon stocks of individual trees in African drylands
This example shows Widou Thiengoly in semi-arid Senegal surrounded by tree plantations, which are partly related to a Great Green Wall34 project aiming to increase tree density and improve livelihoods in the Sahel. a, Tree crown segmentations from the neural net mapping. b, Wood, foliage and root carbon calculated for each tree (Methods). c, Carbon density per hectare aggregated from carbon stocks of single trees to the hectare scale. d, Our viewer includes all information from a to c. This online tool provides information on crown area; foliage, wood and root carbon of single trees; and aggregates carbon to the hectare scale. These data can be accessed by policymakers and stakeholders to monitor areas of interest. The viewer can be accessed at https://trees.pgc.umn.edu/app.
