The study looked at how forests in Shaanxi province, China, stored carbon from 1999 to 2009. By analyzing forest data, they found that carbon storage in the forests increased by over 50% during this time. In 2009, the forests held 0.29 billion tons of carbon, with different types of forests storing varying amounts. Immature forests accounted for two-thirds of the total carbon storage. The results show that after China implemented forest restoration programs, the forests in Shaanxi have the potential to store a lot of carbon, which is good for the environment.
