Analyzes the impacts of elevated carbon dioxide & climate change on forested ecosystems, & the economic feedbacks on harvest patterns & vegetation change on private timberlands in the U.S. Used as a framework linking general circulation model output, an ecosystem model (TEM), models of the forest sector, & a carbon accounting model. Future climates are described with output from the different models. The strong demand for wood products in the future dampens any positive growth effects on forests, for all but the maximum scenario. Charts, tables & maps.
