  abstract = {{T}he phytomass of herbaceous and woody plants is the main source of feed for pastoral livestock in the {S}ahelian savanna. {T}he assessment of the available feed-stock plays a key role in national livestock policies and generally requires many field measurements of both herbaceous and woody plants. {I}n 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. {W}e thus mapped 38 one-hectare plots with a {D}ji {S}park {UAV} in {N}orthern {S}enegal. {T}he herbaceous phy-tomass was measured on the ground. {F}or the woody communities, we evaluated the leaf phytomass using dendrometric parameters combined with allometric equations. {W}e performed partial-least-square regressions between {UAV}-based three-dimension and color indices and phytomass. {R}esults showed a {Q}² (cross-validation results for each response variable) of 0.57 for woody phytomass, 0.68 for herbaceous dry mass, and 0.76 for their fresh mass. {T}his study confirmed the relevance of using low-cost {RGB} {UAV} to assess savanna phytomass.},
