The study estimated the amount of carbon stored in forests in Ba Be National Park, Vietnam, to understand their role in absorbing CO2 and combating climate change. By analyzing 45 forest plots with different levels of richness, the researchers found that rich forests store the most carbon at 273.17 tons per hectare, while poor and rehabilitated forests store less. Overall, the park sequesters about 16,499 tons of carbon annually, helping to improve air quality and reduce greenhouse gas emissions.
