For sites with less than a thousand individuals, the values of palms in the UAV mosaics were based on the count of GPS locations of palms with visible crowns in the canopy at each site. For the sites with a greater number of individuals, the reference values were the total count of manually located crowns in the UAV mosaics. The red lines show the 1:1 relationship in each case.
