Forest ecosystems in China's Three-North Shelterbelt Program region play a crucial role in capturing carbon from the atmosphere. By analyzing data from 1990 to 2015, researchers found that these forests are effective at sequestering carbon, although the overall capacity has slightly decreased over time. The economic value of this carbon sequestration shows that the program is beneficial, with a small investment leading to significant carbon storage benefits. This study provides valuable insights into the carbon sequestration potential of forests in the region, helping guide future forest management decisions.
