摘要

•Digital aerial photogrammetry (DAP) metrics predict woody above ground biomass (AGB).•Relationship of vegetation height metrics to AGB is stable over 4 time steps (35y)•Time gaps between image and field data capture strongly influence model performance.•DAP can provide simple, cost-effective, robust monitoring of woody AGB change.
