Forests in China's Heilongjiang Province are crucial for storing carbon from the atmosphere. Over a 30-year period, researchers estimated the amount of carbon stored in the forests by looking at tree biomass and volume. They found that these forests stored increasing amounts of carbon from 1977 to 2003, indicating they were absorbing more carbon dioxide, a greenhouse gas. The total carbon storage in the forests ranged from 5.413 to 7.916 billion tons during different time periods. This suggests that with good forest management, these areas could become even better at soaking up carbon in the future, helping to combat climate change.
