Forest Gain

Forests worldwide are in a state of flux, with accelerating losses in some regions and gains in others. Given the recognized importance of forest ecosystem services, quantification of global forest extent and change is needed. This map displays the forest gain during the period 2000–2018. Forest gain is defined as the inverse of loss, or a change from non-forest to forest entirely within the study period. It is expressed as either 1 (gain) or 0 (no gain).
