Forest Water Use and the Influence of Precipitation Change
Altered patterns of precipitation associated with regional or global climatic change can be expected to affect ecosystem water use in a manner that reflects, in the case of drought, the response of individual components of that system to soil-water deficits. For temperate deciduous forests, these components include overstory and understory vegetation, the distribution of size classes among seedlings, saplings, and mature trees, and the differences among the many species that occupy these different canopy strata. In addition, consideration must also be given to leaf area dynamics and potential differences among species in their response to environmental variables, including radiation, vapor pressure deficit, and soil-water content.
