Forest processes [Chapter 3]
Some of the changes to U.S. forests will be directly caused by the effects of an altered climate, such as increases in atmospheric carbon dioxide (CO2) temperature (T), and nitrogen (N) deposition on tree growth, mortality, and regeneration. Other changes will be indirectly caused by climate-induced changes in disturbances, such as droughts, fire, insect outbreaks, pathogens, and storms (see Chap. 4). In this chapter, we document current knowledge of the potential direct of climate change on biogeochemical cycling (i.e., carbon [C], nutrients, and water) and forest tree distributions.
