Analyzing forest patch data (IMAGE) University of Maryland Baltimore County Caption Joshua Slaughter (left) and Matthew Fagan discuss a map of forest patches in Costa Rica. A global map of potential natural forest regrowth areas developed in a new Nature study led by Brooke Williams and Hawthorne Beyer and based on a global forest patch database developed by Fagan suggests that an area larger than the size of Mexico in the tropics has the potential to regrow and store 23.4 gigatons of carbon.
