The research was conducted by a WWF-led team that used satellite data to build a map of regenerated forest land. Forest regeneration involves restoring natural woodland with little intervention such as planting native trees and fencing off livestock, or not intervening at all.
Among the biggest reforested lands highlighted by the study is the Atlantic Forest of Brazil, which stretches across a land roughly the size of the Netherlands. Also, in Mongolia’s northern wilderness, 1.2 million hectares of forest have regenerated since 2000. Other regeneration hotspots include central Africa and the boreal forests of Canada.
“Deforestation still claims millions of hectares every year, vastly more than is regenerated,” added Mr. Baldwin-Cantello. “To realize the potential of forests as a climate solution, we need support for regeneration in climate delivery plans and must tackle the drivers of deforestation.”
