Comment on "The extent of forest in dryland biomes"

Science. 2017 Nov 17;358(6365):eaao1309. doi: 10.1126/science.aao1309.


Bastin et al (Reports, 12 May 2017, p. 635) infer forest as more globally extensive than previously estimated using tree cover data. However, their forest definition does not reflect ecosystem function or biotic composition. These structural and climatic definitions inflate forest estimates across the tropics and undermine conservation goals, leading to inappropriate management policies and practices in tropical grassy ecosystems.
