The study looked at how forest vegetation in Northeast China stores carbon under the Natural Forest Protection Program. They examined different types of forests and estimated the amount of carbon stored in them. The results showed that the carbon density in the forests did not vary significantly between different management areas. Overall, the forests under the program stored a total of 1045 TgC of carbon, which is a significant portion of the total carbon storage in the region. The study suggests that continuing to protect natural forests and improving their quality is important for increasing the country's forest carbon sequestration potential and promoting sustainable forest development.
