The increasing amount of atmospheric carbon has been linked with changes in climate, prompting efforts to reduce the amount of carbon emissions. Estimates of forest carbon stocks and stock changes are needed, along with how these change over time, and how sequestration might be increased through forest management activities such as afforestation, reforestation, stand management, and forest protection. Carbon is accrued through increased live biomass and/or increased dead organic matter and soil carbon, whereas carbon is released to the atmosphere through respiration, decomposition, and burning. For large land areas, estimating the amount of carbon sequestration into and out of a forest system involves integrating a number of data sources and models at a variety of spatial and temporal scales. The methods used to integrate data and models across time and spatial scales vary.
In this paper, we present a discussion of methods used to obtain information on carbon stocks for very large land areas, using reported analyses as examples.
