Comment on "The extent of forest in dryland biomes".

چکیده
Bastin et al (Reports, 12 May 2017, p. 635) claim to have discovered 467 million hectares of new dryland forest.

A second shortcoming is that not all sources of uncertainty are considered; the uncertainty could be much higher than the reported value of 3.5%.
