Annual forest expansion

Forest expansion is the sum of afforestation (the establishment of forest through planting and/or deliberate seeding) and natural forest expansion (expansion of foreststhrough natural succession on land that, until then, was under another land use).

Note: The UN FAO publish forest data as the annual average on 10- or 5-year timescales. The following year allocation applies: "1990" is the annual average from 1990 to 2000; "2000" for 2000 to 2010;"2010" for 2010 to 2015; and "2015" for 2015 to 2020.
