Extended Data Fig. 3: Validation of GFC-derived forest loss with high-resolution data.
From: Abrupt increase in harvested forest area over Europe after 2015
a, b, Validation of the classification of harvested areas in the years 2012 and 2017 by forest patches of sizes small (≤0.27 ha) and large (>0.27 ha and ≤4.5 ha; a), and big (>4.5 ha; b). c, Accuracy of harvest area derived from GFC-derived forest loss versus patch size (labels and circle size refer to the EU26-wise cumulative harvested forest).
