Agricultural tree cover is declining globally, and understanding why could help prevent further declines. We applied high-resolution remotely sensed data and multi-method occupancy models to test hypotheses for tree mortality in a tropical pastoral landscape. We found that larger trees - the trees with the highest ecosystem service value in a fragmented landscape- were more likely to die than smaller trees. We also found that the trees with the highest mortality risk are isolated trees, the trees closer to roads, and trees in larger landowner areas. We demonstrate how imperfect detection modeling on aerial imagery can aid landscape conservation.
