FORCARB is an empirical simulation model used to estimate and predict carbon budgets in U.S. forest ecosystems. The model was formulated to characterize dynamics of carbon within forest systems and to analyze carbon flux on timber production is the U.S.

The model uses input data based on output from the Timber Assessment Market Model (TAMM) developed by Adams and Haynes (1980) as well as output from the Aggregated Timberland Assessment System (ATLAS) developed by Mills and Kincade (1992). These are estimates of forest inventory which include data by region, forest type and land ownership. From these input resources, the outputs generated by FORCARB include the inventory of carbon based on timber inventory resources.

The model produces national carbon inventories each decade based on aggregations of regional timber inventories. The carbon inventory is partitioned into that in forest soils, trees, understory vegetation and on the forest floor. Carbon in harvested products is also generated.

VI. Additional remarks

Carbon production in the U.S. and projection of carbon inventories is anessential element of global change. The changing dynamics of carbon is criticalto the planning of forest management in the U.S.
