Using airborne Light Detection and Ranging (LiDAR), we show a low intensity use communal rangeland has a great woody vegetation structural diversity than a neighbouring private protected area. A 3D woody vegetation structural classification was necessary to detect fine-scale, and particularly sub-canopy, change in these semi-arid savannas and should be used in preference of a 2D vegetation classification for monitoring.
