I remember when Vicforests hired a firm I worked for to measure canopy loss. We used drones and satilite data.
Previously they just drove some analysts out to the most tree-covered areas and had them extrapolate from their position on the ground.
After we delivered our result to them, they went back to the old method.
They always play silly games like this. Then you end up with articles a decade later with headlines like “Australia’s deforestation worse than previously known.” With attached quotes like “we couldn’t have possibly known.”
