Abstract
Forests are a major sink for carbon and play an important role in the global carbon cycle. Not only do forests contain huge amounts of carbon, they exchange it very actively with the atmosphere. On average the equivalent of the entire CO2 content of the atmosphere passes through the earth's terrestrial vegetation every 7 years, and about 70% of the entire exchange occurs through forest ecosystems. Because this exchange is so active, expanding the world's forests could present an opportunity to increase the terrestrial carbon sink, and slow the increase in atmospheric CO2 concentration. Average standing stock of carbon over a stand life cycle can range from less than 40 tons C/ha in boreal regions to over 100 tons C/ha in humid temperate regions. Values for tree plantations in the tropics are intermediate because they are often grown on short cycles that preclude high levels of biomass accumulation. Accumulation of biomass and carbon is controlled not only by growth rate, but also by the length of the rotation or life cycle. Costs varied from $99-637/ha and $3-10/ton of stored carbon. An important uncertainty in assessing the total potential of forest management to store atmospheric carbon is the area of land that is both suitable and available for establishing forests. Published estimates of suitable land area in the tropics, for example, vary by a factor of three.
