by Mike Gaworecki on 13 May 2021
As the world searches for solutions to global climate change, tree planting has become increasingly popular, with ambitious campaigns aiming to plant billions or trillions of trees.
These projects often have other environmental goals, too, like regulating water cycles, halting soil erosion and restoring wildlife habitat. They also often have socioeconomic goals, like alleviating poverty.
But how effective is planting trees at accomplishing all this, and how strong is the evidence for this effectiveness? To find out, Mongabay engaged a team of researchers who conducted a non-exhaustive review of relevant scientific literature.

For 149 years, Americans have marked Arbor Day on the last Friday in April by planting trees. Now business leaders, politicians, YouTubers and celebrities are calling for the planting of millions, billions or even trillions of trees to slow climate change.
As ecologists who study forestrestoration, we know that trees store carbon, provide habitat for animals and plants, prevent erosion and create shade in cities. But as we have explained elsewhere in detail, planting trees is not a silver bullet for solving complex environmental and social problems. And for trees to produce benefits, they need to be planted correctly â which often is not the case.
