Policy relevant modeling of the effects of pollutants on tree and forest growth need to achieve two goals. First, they must encapsulate the understanding of the processes by which trees grow and by which pollutants act. Second, they must provide the ability to make plausible projections of the response of trees and forests to alternative pollution scenarios in order to assess the potential effects of regulatory action. Background considerations and an account of work in progress for a modeling system of tree growth designed to meet these needs is presented. The modeling system consists of a series of related models each of which can be studied alone or in concert as they form a whole tree. These individual models are characterized by consideration of both physiology and morphology. Taken together as a Simple Whole Tree (SWT) model they can account for synergies and compensations at the level of the whole tree as it responds to pollutant effects.
