Abstract
A recent PNAS article (1) estimated global gross forest cover loss. Figure 1 in ref. 1 and the conclusions drawn from both refs. 1 and 2 leave the impression that tree cover losses in the southern United States are no different from deforestation activities elsewhere around the globe. Results from the Forest Service’s Forest Inventory and Analysis (FIA) program depict a different, and we think more accurate, assessment of forest conditions in the southern United States, because field plots are used to validate satellite interpretations and distinguish between land cover and land use changes.
