Abstract

Canada’s ambitious Two Billion Trees (2BT) program aims not only to mitigate climate change but also to safeguard biodiversity and improve human well-being. Remarkably, the country has 19.1 million hectares of land suitable for forest restoration—15 times more than the area needed to meet the program’s target (1.2 million hectares). The real challenge, therefore, is not where to plant but how to plant wisely.
