Unmanned aerial vehicle for the assessment of woody and herbaceous phytomass in Sahelian savanna ; Un dron para la evaluación de la fitomasa leñosa y herbácea de las sabanas sahelianas ; Un drone pour l’évaluation de la phytomasse ligneuse et herbacée des savanes sahéliennes

The phytomass of herbaceous and woody plants is the main source of feed for pastoral livestock in the Sahelian savanna. The assessment of the available feedstock plays a key role in national livestock policies and generally requires many field measurements of both herbaceous and woody plants. In this study, we tested the possibility of using a red-green-blue (RGB) unmanned aerial vehicle (UAV) to evaluate the phytomass of both woody and herbaceous species. We thus mapped 38 one hectare plots with a Dji Spark UAV in Northern Senegal. The herbaceous phytomass was measured on the ground. For the... Mehr ...
