For a given time period, this indicator will spatially map changes in carbon stocks on forestlands where forests, forestland losses. forestland gains, and forest products are acting as: a) net sources of carbon dioxide through releases of carbon to the atmosphere, b) net sinks for carbon storage through the removal of carbon dioxide from the atmosphere, or c) neither sources or sinks. Through the use of this indicator, forest managers, policy makers and the public will be able to see the changes in the carbon sink capacity on the state’s forestlands from the interaction over a given period of time of disturbance, land use change, forest management, and forest product manufacture efficiency and utilization. By comparing indicator results over successive time periods,
