Description: This report summarizes the major features of logic, assumptions, structure, and functioning of an ecosystem simulation model affectionately called "SAGE" (Sagebrush And Grass Ecosystem). The SAGE simulation model addresses a generalized sagebrush-grass grazingland ecosystem type typical of those in the western U.S.A. ... The report describes the ecosystem which is modelled, the conceptual framework for the model, specific functional relationships used in the submodels, and technical aspects of the simulation methodology.
