China’s biomass and forest area have markedly increased over the past decades, according to the country's international reporting of forest resources. As in the United States, such reporting is important for climate negotiations. But little is known internationally about how China measures its own forests across such a broad area or whether its measurements are consistent over time. Forest Service research ecologist Sean Healey worked with an international team of scientists to describe Chinese efforts to report the status and trends of the country’s forests. Chinese inventory methods and definitions have changed over the decades and efforts to cross-walk consistent methods across time show significant increases in the country’s forest resources. Like other countries, China has gradually integrated new technology into its inventory, and it has moved toward methods that increase consistency and precision in national estimates. China does not yet freely distribute inventory data, but collaborations like this one help make its methods and results more transparent.
