Forests could regrow naturally on more than 800,000 square miles of land around the tropics, without need for planting trees by hand, a new study finds.
In some places, lands are so degraded that it is necessary to plant trees by hand, but manual planting is costly and prone to failure. Forests that regrow naturally tend to fare better and host a richer array of wildlife.
For the study, researchers mapped areas where forests would be likely to regrow — areas where soils are healthy and there is already forest nearby to supply seeds. They found that, in total, these spots would cover an area larger than Mexico.
