Field teams count and measure a sample of rows and extrapolate across the block. On estates of tens of thousands of hectares, that sample is a sliver.
Hidden losses
A missing tree is lost yield nobody sees.
Trees die, fail to establish or are never replanted. Each gap is yield lost for years, and from the air a closed canopy hides it.
Seen from above
Crowns merge; stems disappear.
Satellite and above-canopy imagery see a carpet of crowns. Where the canopy closes, telling trees apart, let alone measuring their stems, gets unreliable.
Averaged forecasts
Harvest is forecast from averages.
Yield and volume forecasts lean on planted density and growth tables, not on what is actually standing in each block.
Short-handed
Counting by hand is slow and costly.
Every manual count ties up field teams for weeks, and it has to be repeated every season.
Remote
The estates with the most trees have the least signal.
Tools that need a connection in the field don't work across remote plantations.
From capture to value
From a corridor scan to a crew list you can defend.
