摘要
•Global primary forest decreased by 2.5% (10% in the tropics) from 1990 to 2015.•98% of primary forest occurred in 25 countries, with half in developed countries.•Additional investment may be needed to improve primary forest area data quality.•Formally protected forest areas increased more than 50% from 1990 to 2015.•Changes in protection are positively correlated with changes in forest area.
