Abstract
The 1999 forest and rangeland condition indicator model is a set of independent econometric production functions for environmental outputs (measured with condition indicators) at the national scale. This report documents the development of the database and the statistical estimation required by this particular production structure with emphasis on two special characteristics of environmental output production processes: (1) the independence of ecological systems from human control, and (2) the broadscale spatial nature of these processes. Resolution of data deficiencies also is examined. Finally, the model projections are presented and discussed by using nationalscale maps.
